+More complete build documentation is available on the libarchive
+Wiki:  http://libarchive.googlecode.com/
+
+On most Unix-like systems, you should be able to install libarchive,
+bsdtar, and bsdcpio using the following common steps:
+    ./configure
+    make
+    make install
+
+If you need to customize the target directories or otherwise adjust
+the build setting, use
+    ./configure --help
+to list the configure options.
+
+If you are developing libarchive and need to update the
+configure script and other build files:
+    /bin/sh build/autogen.sh
+
+To create a distribution, please use the 'distcheck' target:
+    /bin/sh build/autogen.sh && ./configure && make distcheck
+
+On non-Unix-like systems, use the "cmake" utility (available from
+http://cmake.org/) to generate suitable build files for your platform.
+Cmake requires the name of the directory containing CmakeLists.txt and
+the "generator" to use for your build environment.  For example, to
+build with Xcode on Mac OS, you can use the following command:
+    cmake -G "Xcode" ~/libarchive-download-dir/
+The result will be appropriate makefiles, solution files, or project
+files that can be used with the corresponding development tool.
+See the libarchive Wiki or the cmake site for further documentation.

+
+Nov 07, 2008: Read filter refactor: The decompression routines just
+       consume and produce arbitrarily-sized blocks.  The reblocking
+       from read_support_compression_none() has been pulled into the
+       read core.  Also, the decompression bid now makes multiple
+       passes and stacks read filters.

+Oct 19, 2008: Internal read_ahead change: short reads are now an error
+Oct 06, 2008: bsdtar: option parser no longer uses getopt_long(),

+Sep 17, 2008: Miklos Vajna: lzma reader and test.  Note:  I still have
+       some concerns about the auto-detection (LZMA file format
+       doesn't support auto-detection well), so this is not yet
+       enabled under archive_read_support_compression_all().  For
+       now, you must call archive_read_support_compression_lzma() if
+       you want LZMA read support.
+Sep 11, 2008: Ivailo Petrov: Many fixes to Windows build, new solution files
+Jul 26, 2008: archive_entry now tracks which values have not been set.
+       This helps zip extraction (file size is often "unknown") and
+       time restores (tar usually doesn't know atime).
+Jul 26, 2008: Joerg Sonnenberger: Performance improvements to shar writer
+Jul 25, 2008: Joerg Sonnenberger: mtree write support

+
+May 16, 2008: bsdtar's test harness no longer depends on file ordering.
+        This was causing spurious test failures on a lot of systems.
+        Thanks to Bernhard R. Link for the diagnosis.
+
+May 14, 2008: Joerg Sonnenberger: -s substitution support for bsdtar
+

+
+May 11, 2008: Joerg Sonnenberger: fix hardlink extraction when

+
+April 30, 2008: Primary libarchive work has been moved into the FreeBSD

+        //depot/user/kientzle/libarchive-portable
+        Direct link: http://preview.tinyurl.com/46mdgr
+
+May 04, 2008: libarchive 2.5.3b released
+       * libarchive: Several fixes to link resolver to address bsdcpio crashes
+       * bsdcpio: -p hardlink handling fixes
+       * tar/pax: Ensure ustar dirnames end in '/'; be more careful about
+         measuring filenames when deciding what pathname fields to use
+       * libarchive: Mark which entry strings are set; be accurate about
+         distinguishing empty strings ("") from unset ones (NULL)
+       * tar: Don't crash reading entries with empty filenames
+       * libarchive_test, bsdtar_test, bsdcpio_test:  Better detaults:
+         run all tests, delete temp dirs, summarize repeated failures
+       * -no-undefined to libtool for Cygwin
+       * libarchive_test: Skip large file tests on systems with 32-bit off_t
+       * iso9660: Don't bother trying to find the body of an empty file;
+         this works around strange behavior from some ISO9660 writers
+       * tar: allow -r -T to be used together
+       * tar: allow --format with -r or -u
+       * libarchive: Don't build archive.h
+
+May 04, 2008: Simplified building: archive.h is no longer constructed
+       This may require additional #if conditionals on some platforms.
+
+Mar 30, 2008: libarchive 2.5.1b released
+
+Mar 15, 2008: libarchive 2.5.0b released
+Mar 15, 2008: bsdcpio now seems to correctly write hardlinks into newc,
+       ustar, and old cpio archives.  Just a little more testing before
+       bsdcpio 1.0 becomes a reality.
+Mar 15, 2008: I think the new linkify() interface is finally handling
+       all known hardlink strategies.
+Mar 15, 2008: Mtree read fixes from Joerg Sonnenberger.
+Mar 15, 2008: Many new bsdtar and bsdcpio options from Joerg Sonnenberger.
+Mar 15, 2008: test harnesses no longer require uudecode; they
+       now have built-in decoding logic that decodes the reference
+       files as they are needed.
+
+Mar 14, 2008: libarchive 2.4.14 released; identical to 2.4.13 except for
+       a point fix for gname/uname mixup in pax format that was introduced
+       with the UTF-8 fixes.
+
+Feb 26, 2008: libarchive 2.4.13 released
+Feb 25, 2008: Handle path, linkname, gname, or uname that can't be converted
+       to/from UTF-8.  Implement "hdrcharset" attribute from SUS-2008.
+Feb 25, 2008: Fix name clash on NetBSD.
+Feb 18, 2008: Fix writing empty 'ar' archives, per Kai Wang
+Feb 18, 2008: [bsdtar] Permit appending on block devices.
+Feb 09, 2008: New "linkify" resolver to help with newc hardlink writing;
+       bsdcpio still needs to be converted to use this.
+Feb 02, 2008: Windows compatibility fixes from Ivailo Petrov, Kees Zeelenberg
+Jan 30, 2008: Ignore hardlink size for non-POSIX tar archives.
+
+Jan 22, 2008: libarchive 2.4.12 released
+Jan 22, 2008: Fix bad padding when writing symlinks to newc cpio archives.
+Jan 22, 2008: Verify bsdcpio_test by getting it to work against GNU cpio 2.9.
+       bsdcpio_test complains about missing options (-y and -z), format
+       of informational messages (--version, --help), and a minor formatting
+       issue in odc format output.  After this update, bsdcpio_test uncovered
+       several more cosmetic issues in bsdcpio, all now fixed.
+Jan 22, 2008: Experimental support for self-extracting Zip archives.
+Jan 22, 2008: Extend hardlink restore strategy to work correctly with
+       hardlinks extracted from newc cpio files.  (Which store the body
+       only with the last occurrence of a link.)
+
+Dec 30, 2007: libarchive 2.4.11 released
+Dec 30, 2007: Fixed a compile error in bsdcpio on some systems.
+
+Dec 29, 2007: libarchive 2.4.10 released
+Dec 29, 2007: bsdcpio 0.9.0 is ready for wider use.
+Dec 29, 2007: Completed initial test harness for bsdcpio.
+
+Dec 22, 2007: libarchive 2.4.9 released
+Dec 22, 2007: Implement the remaining options for bsdcpio:  -a, -q, -L, -f,
+       pattern selection for -i and -it.
+
+Dec 13, 2007: libarchive 2.4.8 released
+Dec 13, 2007: gzip and bzip2 compression now handle zero-byte writes correctly,
+       Thanks to Damien Golding for bringing this to my attention.
+
+Dec 12, 2007: libarchive 2.4.7 released
+
+Dec 10, 2007: libarchive 2.4.6 released

+Dec 03, 2007: Thanks to Lapo Luchini for sending me a ZIP file that
+       libarchive couldn't handle.  Fixed a bug in handling of
+       "length at end" flags in ZIP files.
+Dec 03, 2007: Fixed bsdcpio -help, bsdtar -help tests.
+Dec 02, 2007: First cut at real bsdtar test harness.
+
+Dec 02, 2007: libarchive 2.4.2 released
+
+Dec 02, 2007: libarchive 2.4.1 released
+Dec 02, 2007: Minor fixes, rough cut of mdoc-to-man conversion for
+       man pages.
+
+Oct 30, 2007: libarchive 2.4.0 released
+Oct 30, 2007: Minor compile fix thanks to Joerg Schilling.
+Oct 30, 2007: Only run the format auction once at the beginning of the
+       archive.  This is simpler and supports better error recovery.
+Oct 29, 2007: Test support for very large entries in tar archives:
+       libarchive_test now exercises entries from 2GB up to 1TB.
+
+Oct 27, 2007: libarchive 2.3.5 released
+Oct 27, 2007: Correct some unnecessary internal data copying in the
+       "compression none" reader and writer; this reduces user time
+       by up to 2/3 in some tests.  (Thanks to Jan Psota for
+       publishing his performance test results to GNU tar's bug-tar
+       mailing list; those results pointed me towards this problem.)
+Oct 27, 2007: Fix for skipping archive entries that are exactly
+       a multiple of 4G on 32-bit platforms.
+Oct 25, 2007: Fix for reading very large (>8G) tar archives; this was
+       broken when I put in support for new GNU tar sparse formats.
+Oct 20, 2007: Initial work on new pattern-matching code for cpio; I
+       hope this eventually replaces the code currently in bsdtar.
+
+Oct 08, 2007: libarchive 2.3.4 released
+Oct 05, 2007: Continuing work on bsdcpio test suite.
+Oct 05, 2007: New cpio.5 manpage, updates to "History" of bsdcpio.1 and
+       bsdtar.1 manpages.
+Oct 05, 2007: Fix zip reader to immediately return EOF if you try
+       to read body of non-regular file.  In particular, this fixes
+       bsdtar extraction of zip archives.
+
+Sep 30, 2007: libarchive 2.3.3 released
+Sep 26, 2007: Rework Makefile.am so that the enable/disable options
+       actually do the right things.
+Sep 26, 2007: cpio-odc and cpio-newc archives no longer write bodies
+       for non-regular files.
+Sep 26, 2007: Test harness for bsdcpio is in place, needs more tests written.
+       This is much nicer than the ragtag collection of test scripts
+       that bsdtar has.
+
+Sep 20, 2007: libarchive 2.3.2 released
+Sep 20, 2007: libarchive 2.3.1 broke bsdtar because the archive_write_data()
+       fix was implemented incorrectly.
+
+Sep 16, 2007: libarchive 2.3.1 released
+Sep 16, 2007: Many fixes to bsdcpio 0.3:  handle hardlinks with -p, recognize
+       block size on writing, fix a couple of segfaults.
+Sep 16, 2007: Fixed return value from archive_write_data() when used
+       with archive_write_disk() to match the documentation and other
+       instances of this same function.
+Sep 15, 2007: Add archive_entry_link_resolver, archive_entry_strmode
+
+Sep 11, 2007: libarchive 2.2.8 released
+Sep 09, 2007: bsdcpio 0.2 supports most (not yet all) of the old POSIX spec.
+
+Sep 01, 2007: libarchive 2.2.7 released
+Aug 31, 2007: Support for reading mtree files, including an mtree.5 manpage
+       (A little experimental still.)
+Aug 18, 2007: Read gtar 1.17 --posix --sparse entries.
+Aug 13, 2007: Refined suid/sgid restore handling; it is no longer
+       an error if suid/sgid bits are dropped when you request
+       perm restore but don't request owner restore.
+Aug 06, 2007: Use --enable-bsdcpio if you want to try bsdcpio
+
+Aug 05, 2007: libarchive 2.2.6 released
+Aug 05, 2007: New configure option --disable-bsdtar, thanks to Joerg
+       Sonnenberger.
+Aug 05, 2007: Several bug fixes from FreeBSD CVS repo.
+
+Jul 13, 2007: libarchive 2.2.5 released
+
+Jul 12, 2007: libarchive 2.2.4 released
+Jul 12, 2007: Thanks to Colin Percival's help in diagnosing and
+       fixing several critical security bugs.  Details available at
+       http://security.freebsd.org/advisories/FreeBSD-SA-07:05.libarchive.asc
+
+May 26, 2007: libarchive 2.2.3 released
+May 26, 2007: Fix memory leaks in ZIP reader and shar writer, add some
+       missing system headers to archive_entry.h, dead code cleanup
+       from Colin Percival, more tests for gzip/bzip2, fix an
+       EOF anomaly in bzip2 decompression.
+
+May 12, 2007: libarchive 2.2.2 released
+May 12, 2007: Fix archive_write_disk permission restore by cloning
+       entry passed into write_header so that permission info is
+       still available at finish_entry time.  (archive_read_extract()
+       worked okay because it held onto the passed-in entry, but
+       direct consumers of archive_write_disk would break).  This
+       required fixing archive_entry_clone(), which now works and has
+       a reasonably complete test case.
+May 10, 2007: Skeletal cpio implementation.
+
+May 06, 2007: libarchive 2.2.1 released
+May 06, 2007: Flesh out a lot more of test_entry.c so as to catch
+       problems such as the device node breakage before releasing <sigh>.
+May 05, 2007: Fix a bad bug introduced in 2.1.9 that broke device
+       node entries in tar archives.
+May 03, 2007: Move 'struct stat' out of archive_entry core as well.
+       This removes some portability headaches and fixes a bunch
+       of corner cases that arise when manipulating archives on
+       dissimilar systems.
+
+Apr 30, 2007: libarchive 2.1.10 released
+Apr 31, 2007: Minor code cleanup.
+
+Apr 24, 2007: libarchive 2.1.9 released
+Apr 24, 2007: Fix some recently-introduced problems with libraries
+       (Just let automake handle it and it all works much better.)
+       Finish isolating major()/minor()/makedev() in archive_entry.c.
+
+Apr 23, 2007: libarchive 2.1.8 released
+Apr 23, 2007: Minor fixes found from building on MacOS X
+
+Apr 22, 2007: libarchive 2.1.7 released
+Apr 22, 2007: Eliminated all uses of 'struct stat' from the
+       format readers/writers.  This should improve portability;
+       'struct stat' is now only used in archive_entry and in
+       code that actually touches the disk.
+
+Apr 17, 2007: libarchive 2.1.6 released
+       Libarchive now compiles and passes all tests on Interix.
+
+Apr 16, 2007: libarchive 2.1.5 released
+
+Apr 15, 2007: libarchive 2.1b2 released
+Apr 15, 2007: New libarchive_internals.3 documentation of internal APIs.
+       Not complete, but should prove helpful.
+Apr 15, 2007: Experimental "read_compress_program" and "write_compress_program"
+       for using libarchive with external compression.  Not yet
+       well tested, and likely has portability issues.  Feedback
+       appreciated.
+
+Apr 14, 2007: libarchive 2.0.31 released
+Apr 14, 2007: More fixes for Interix, more 'ar' work
+
+Apr 14, 2007: libarchive 2.0.30 released
+Apr 13, 2007: libarchive now enforces trailing '/' on dirs
+       written to tar archives
+
+Apr 11, 2007: libarchive 2.0.29 released
+Apr 11, 2007: Make it easier to statically configure for different platforms.
+Apr 11, 2007: Updated config.guess, config.sub, libtool
+
+Apr 06, 2007: libarchive 2.0.28 released
+Apr 06, 2007: 'ar' format read/write support thanks to Kai Wang.
+
+Apr 01, 2007: libarchive 2.0.27 released
+Mar 31, 2007: Several minor fixes from Colin Percival and Joerg Sonnenberger.
+
+Mar 12, 2007: libarchive 2.0.25 released
+Mar 12, 2007: Fix broken --unlink flag.
+
+Mar 11, 2007: libarchive 2.0.24 released
+Mar 10, 2007: Correct an ACL blunder that causes any ACL with an entry
+    that refers to a non-existent user or group to not be restored correctly.
+    The fix both makes the parser more tolerant (so that archives created
+    with the buggy ACLs can be read now) and corrects the ACL formatter.
+Mar 10, 2007: More work on test portability to Linux.
+
+Mar 10, 2007: libarchive 2.0.22 released
+Mar 10, 2007: Header cleanups; added linux/fs.h, removed
+    some unnecessary headers, added #include guards in bsdtar.
+    If you see any obvious compile failures from this, let me know.
+Mar 10, 2007: Work on bsdtar test scripts: not yet robust enough
+    to enable as part of "make check", but getting better.
+Mar 10, 2007: libarchive now returns ARCHIVE_FAILED when
+    a header write fails in a way that only affects this item.
+    Less bad than ARCHIVE_FATAL, but worse than ARCHIVE_WARN.
+
+Mar 07, 2007: libarchive 2.0.21 released
+Mar 07, 2007: Add some ACL tests (only for the system-independent
+    portion of the ACL support for now).
+Mar 07, 2007: tar's ability to read ACLs off disk got
+    turned off for FreeBSD; re-enable it.  (ACL restores and
+    libarchive support for storing/reading ACLs from pax
+    archives was unaffected.)
+
+Mar 02, 2007: libarchive 2.0.20 released
+Mar 2, 2007:  It's not perfect, but it's pretty good.
+    Libarchive 2.0 is officially out of beta.
+
+Feb 28, 2007: libarchive 2.0b17 released
+Feb 27, 2007: Make the GID restore checks more robust by checking
+    whether the current user has too few or too many privileges.
+
+Feb 26, 2007: libarchive 2.0b15 released
+Feb 26, 2007: Don't lose symlinks when extracting from ISOs.
+    Thanks to Diego "Flameeyes" Pettenò for telling me about the
+    broken testcase on Gentoo that (finally!) led me to the cause
+    of this long-standing bug.
+
+Feb 26, 2007: libarchive 2.0b14 released
+Feb 26, 2007: Fix a broken test on platforms that lack lchmod().
+
+Feb 25, 2007: libarchive 2.0b13 released
+Feb 25, 2007: Empty archives were being written as empty files,
+    without a proper end-of-archive marker.  Fixed.
+
+Feb 23, 2007: libarchive 2.0b12 released
+Feb 22, 2007: Basic security checks added: _EXTRACT_SECURE_NODOTDOT
+    and _EXTRACT_SECURE_SYMLINK.  These checks used to be in bsdtar,
+    but they belong down in libarchive where they can be used by
+    other tools and where they can be better optimized.
+
+Feb 11, 2007: libarchive 2.0b11 released
+Feb 10, 2007: Fixed a bunch of errors in libarchive's handling
+    of EXTRACT_PERM and EXTRACT_OWNER, especially relating
+    to SUID and SGID bits.
+
+Jan 31, 2007: libarchive 2.0b9 released
+Jan 31, 2007: Added read support for "empty" archives as a
+    distinct archive format.  Bsdtar uses this to handle, e.g.,
+    "touch foo.tar; tar -rf foo.tar"
+
+Jan 22, 2007: libarchive 2.0b6 released
+Jan 22, 2007: archive_write_disk API is now in place.  It provides
+    a finer-grained interface than archive_read_extract.  In particular,
+    you can use it to create objects on disk without having an archive
+    around (just feed it archive_entry objects describing what you
+    want to create), you can override the uname/gname-to-uid/gid lookups
+    (minitar uses this to avoid getpwXXX() and getgrXXX() bloat).
+
+Jan 09, 2007: libarchive 2.0a3 released
+Jan 9, 2007: archive_extract is now much better; it handles the
+    most common cases with a minimal number of system calls.
+    Some features still need a lot of testing, especially corner
+    cases involving objects that already exist on disk.   I expect
+    the next round of API overhaul will simplify building test cases.
+Jan 9, 2007: a number of fixes thanks to Colin Percival, especially
+    corrections to the skip() framework and handling of large files.
+Jan 9, 2007: Fixes for large ISOs.  The code should correctly handle
+    very large ISOs with entries up to 4G.   Thanks to Robert Sciuk
+    for pointing out these issues.
+
+Sep 05, 2006: libarchive 1.3.1 released
+Sep 5, 2006: Bump version to 1.3 for new I/O wrappers.
+Sep 4, 2006: New memory and FILE read/write wrappers.
+Sep 4, 2006: libarchive test harness is now minimally functional;
+    it's located a few minor bugs in error-handling logic
+
+Aug 17, 2006: libarchive 1.2.54 released
+Aug 17, 2006: Outline ABI changes for libarchive 2.0; these
+   are protected behind #ifdef's until I think I've found everything
+   that needs to change.
+Aug 17, 2006: Fix error-handling in archive_read/write_close()
+   They weren't returning any errors before.
+Aug 17, 2006: Fix recursive-add logic to not trigger if it's not set
+   Fixes a bug adding files when writing archive to pipe or when
+   using archive_write_open() directly.
+Jul 2006: New "skip" handling improves performance extracting
+   single files from large uncompressed archives.
+
+Mar 21, 2006: 1.2.52 released
+Mar 21, 2006: Fix -p on platforms that don't have platform-specific
+   extended attribute code.
+Mar 20, 2006: Add NEWS file; fill in some older history from other
+   files.  I'll try to keep this file up-to-date from now on.
+
+OLDER NEWS SUMMARIES
+
+Mar 19, 2006: libarchive 1.2.51 released
+Mar 18, 2006: Many fixes to extended attribute support, including a redesign
+   of the storage format to simplify debugging.
+Mar 12, 2006: Remove 'tp' support; it was a fun idea, but not worth
+   spending much time on.
+Mar 11, 2006: Incorporated Jaakko Heinonen's still-experimental support
+   for extended attributes (Currently Linux-only.).
+Mar 11, 2006: Reorganized distribution package: There is now one tar.gz
+   file that builds both libarchive and bsdtar.
+Feb 13, 2006: Minor bug fixes: correctly read cpio device entries, write
+   Pax attribute entry names.
+Nov 7, 2005: Experimental 'tp' format support in libarchive.  Feedback
+   appreciated; this is not enabled by archive_read_support_format_all()
+   yet as I'm not quite content with the format detection heuristics.
+Nov 7, 2005: Some more portability improvements thanks to Darin Broady,
+   minor bugfixes.
+Oct 12, 2005: Use GNU libtool to build shared libraries on many systems.
+Aug 9, 2005: Correctly detect that MacOS X does not have POSIX ACLs.
+Apr 17, 2005: Kees Zeelenberg has ported libarchive and bsdtar to Windows:
+   http://gnuwin32.sourceforge.net/
+Apr 11, 2005: Extended Zip/Zip64 support thanks to Dan Nelson.  -L/-h
+   fix from Jaakko Heinonen.
+Mar 12, 2005: archive_read_extract can now handle very long
+   pathnames (I've tested with pathnames up to 1MB).
+Mar 12, 2005: Marcus Geiger has written an article about libarchive
+   http://xsnil.antbear.org/2005/02/05/archive-mit-libarchive-verarbeiten/
+   including examples of using it from Objective-C.  His MoinX
+   http://moinx.antbear.org/ desktop Wiki uses
+   libarchive for archiving and restoring Wiki pages.
+Jan 22, 2005: Preliminary ZIP extraction support,
+    new directory-walking code for bsdtar.
+Jan 16, 2005: ISO9660 extraction code added; manpage corrections.
+May 22, 2004: Many gtar-compatible long options have been added; almost
+    all FreeBSD ports extract correctly with bsdtar.
+May 18, 2004: bsdtar can read Solaris, HP-UX, Unixware, star, gtar,
+    and pdtar archives.

+README for libarchive bundle.
+
+Questions?  Issues?
+   * http://libarchive.googlecode.com/ is the home for ongoing
+     libarchive development, including issue tracker, additional
+     documentation, and links to the libarchive mailing lists.
+
+This distribution bundle includes the following components:
+   * libarchive: a library for reading and writing streaming archives
+   * tar: the 'bsdtar' program is a full-featured 'tar'
+          replacement built on libarchive
+   * cpio: the 'bsdcpio' program is a different interface to
+          essentially the same functionality
+   * examples: Some small example programs that you may find useful.
+   * examples/minitar: a compact sample demonstrating use of libarchive.
+          I use this for testing link pollution; it should produce a very
+          small executable file on most systems.
+   * contrib:  Various items sent to me by third parties;
+          please contact the authors with any questions.
+
+The top-level directory contains the following information files:
+   * NEWS - highlights of recent changes
+   * COPYING - what you can do with this
+   * INSTALL - installation instructions
+   * README - this file
+   * configure - configuration script, see INSTALL for details.
+   * CMakeLists.txt - input for "cmake" build tool, see INSTALL
+
+The following files in the top-level directory are used by the
+'configure' script:
+   * Makefile.am, aclocal.m4, configure.ac
+       - used to build this distribution, only needed by maintainers
+   * Makefile.in, config.h.in
+       - templates used by configure script
+
+Guide to Documentation installed by this system:
+ * bsdtar.1 explains the use of the bsdtar program
+ * bsdcpio.1 explains the use of the bsdcpio program
+ * libarchive.3 gives an overview of the library as a whole
+ * archive_read.3, archive_write.3, archive_write_disk.3, and
+   archive_read_disk.3 provide detailed calling sequences for the read
+   and write APIs
+ * archive_entry.3 details the "struct archive_entry" utility class
+ * archive_internals.3 provides some insight into libarchive's
+   internal structure and operation.
+ * libarchive-formats.5 documents the file formats supported by the library
+ * cpio.5, mtree.5, and tar.5 provide detailed information about these
+   popular archive formats, including hard-to-find details about
+   modern cpio and tar variants.
+The manual pages above are provided in the 'doc' directory in
+a number of different formats.
+
+You should also read the copious comments in "archive.h" and the
+source code for the sample programs for more details.  Please let me
+know about any errors or omissions you find.
+
+Currently, the library automatically detects and reads the following:
+  * gzip compression
+  * bzip2 compression
+  * compress/LZW compression
+  * lzma and xz compression
+  * GNU tar format (including GNU long filenames, long link names, and
+    sparse files)
+  * Solaris 9 extended tar format (including ACLs)
+  * Old V7 tar archives
+  * POSIX ustar
+  * POSIX pax interchange format
+  * POSIX octet-oriented cpio
+  * SVR4 ASCII cpio
+  * POSIX octet-oriented cpio
+  * Binary cpio (big-endian or little-endian)
+  * ISO9660 CD-ROM images (with optional Rockridge or Joliet extensions)
+  * ZIP archives (with uncompressed or "deflate" compressed entries)
+  * GNU and BSD 'ar' archives
+  * 'mtree' format
+
+The library can write:
+  * gzip compression
+  * bzip2 compression
+  * compress/LZW compression
+  * lzma and xz compression
+  * POSIX ustar
+  * POSIX pax interchange format
+  * "restricted" pax format, which will create ustar archives except for
+    entries that require pax extensions (for long filenames, ACLs, etc).
+  * POSIX octet-oriented cpio
+  * SVR4 "newc" cpio
+  * shar archives
+  * ZIP archives (with uncompressed or "deflate" compressed entries)
+  * GNU and BSD 'ar' archives
+  * 'mtree' format
+
+Notes about the library architecture:
+
+ * This is a heavily stream-oriented system.  There is no direct
+   support for in-place modification or random access.
+
+ * The library is designed to be extended with new compression and
+   archive formats.  The only requirement is that the format be
+   readable or writable as a stream and that each archive entry be
+   independent.  There are articles on the libarchive Wiki explaining
+   how to extend libarchive.
+
+ * On read, compression and format are always detected automatically.
+
+ * I've attempted to minimize static link pollution.  If you don't
+   explicitly invoke a particular feature (such as support for a
+   particular compression or format), it won't get pulled in.
+   In particular, if you don't explicitly enable a particular
+   compression or decompression support, you won't need to link
+   against the corresponding compression or decompression libraries.
+   This also reduces the size of statically-linked binaries in
+   environments where that matters.
+
+ * On read, the library accepts whatever blocks you hand it.
+   Your read callback is free to pass the library a byte at a time
+   or mmap the entire archive and give it to the library at once.
+   On write, the library always produces correctly-blocked output.
+
+ * The object-style approach allows you to have multiple archive streams
+   open at once.  bsdtar uses this in its "@archive" extension.
+
+ * The archive itself is read/written using callback functions.
+   You can read an archive directly from an in-memory buffer or
+   write it to a socket, if you wish.  There are some utility
+   functions to provide easy-to-use "open file," etc, capabilities.
+
+ * The read/write APIs are designed to allow individual entries
+   to be read or written to any data source:  You can create
+   a block of data in memory and add it to a tar archive without
+   first writing a temporary file.  You can also read an entry from
+   an archive and write the data directly to a socket.  If you want
+   to read/write entries to disk, there are convenience functions to
+   make this especially easy.
+
+ * Note: "pax interchange format" is really an extended tar format,
+   despite what the name says.

+# These exist entirely to fool aclocal when bootstrapping libtool.
+#
+# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
+# which have later been changed to m4_define as they aren't part of the
+# exported API, or moved to Autoconf or Automake where they belong.
+#
+# The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
+# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
+# using a macro with the same name in our local m4/libtool.m4 it'll
+# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
+# and doesn't know about Autoconf macros at all.)
+#
+# So we provide this file, which has a silly filename so it's always
+# included after everything else.  This provides aclocal with the
+# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
+# because those macros already exist, or will be overwritten later.
+# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6. 
+#
+# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
+# Yes, that means every name once taken will need to remain here until
+# we give up compatibility with versions before 1.7, at which point
+# we need to keep only those names which we still refer to.
+

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an

+# - Macro approximating the CMake 2.8 ADD_TEST(NAME) signature.
+# ADD_TEST_28(NAME <name> COMMAND <command> [arg1 [arg2 ...]])
+#  <name>    - The name of the test
+#  <command> - The test executable
+#  [argN...] - Arguments to the test executable
+# This macro approximates the ADD_TEST(NAME) signature provided in
+# CMake 2.8 but works with CMake 2.6 too.  See CMake 2.8 documentation
+# of ADD_TEST()for details.
+#
+# This macro automatically replaces a <command> that names an
+# executable target with the target location.  A generator expression
+# of the form "$<TARGET_FILE:tgt>" is supported in both the command
+# and arguments of the test.  Howerver, this macro only works for
+# targets without per-config output name properties set.
+#
+# Example usage:
+#   add_test(NAME mytest COMMAND testDriver --exe $<TARGET_FILE:myexe>)
+# This creates a test "mytest" whose command runs a testDriver tool
+# passing the full path to the executable file produced by target
+# "myexe".

+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.

+dnl @synopsis ST_LIB_ARCHIVE([ENABLED-DEFAULT])
+dnl
+dnl This macro figures out what's necessary to link a program against an
+dnl instance of the BSD libarchive package by Tim Kientzle.
+dnl 
+dnl See http://people.freebsd.org/~kientzle/libarchive/ for more info.
+dnl
+dnl It exports and substitutes the variables LIBARCHIVE_LIBS, LIBARCHIVE_LDFLAGS,
+dnl and LIBARCHIVE_CPPFLAGS to appropriate values for the identified instance of
+dnl libarchive.  The values are AC_SUBST'd, so a user could, for example, simply
+dnl include @LIBARCHIVE_CPPFLAGS@ in the definition of AM_CPPFLAGS in a Makefile.am.
+dnl
+dnl ENABLED-DEFAULT is either "yes" or "no" and determines whether the default value
+dnl is --with-libarchive or --without-libarchive.  It is not possible to specify a
+dnl default directory.  More simply, any reasonable choice for a default should just
+dnl go into the auto-detect list.
+dnl
+dnl The macro defines the symbol HAVE_LIBARCHIVE if the library is found. You
+dnl should use autoheader to include a definition for this symbol in a config.h
+dnl file. Sample usage in a C/C++ source is as follows:
+dnl
+dnl   #ifdef HAVE_LIBARCHIVE
+dnl   #include <archive.h>
+dnl   #endif /* HAVE_LIBARCHIVE */

+ODP: [Bug-tar] GNU tar, star and BSD tar speed comparision +new script
+
+Jan Psota
+Thu, 25 Oct 2007 06:51:13 -0700
+
+Latest TCP script at the bottom (3180 bytes).
+4 tests: 64bit dual core Athlon tmpfs / disk (reiserfs) - 60MB/s,
+        32bit Athlon tmpfs / disk (reiserfs) - 55MB/s
+Both machines were idle -- used for testing only.
+Tarball and extracted files were on different physical devices.
+Test data: linux 2.6.22/3 kernel sources for memory operations,
+for the other data average file size should bring enough info.
+
+2 x [...] processor means 1 processor with 2 cores (2 entries in cpuinfo).
+Archive format is set to pax (Joerg).
+Let's end with it. I only wanted to send You a new version of TCP script :-).

+TCP, version $version
+TCP stands for Tar Comparision Program here.
+It currently compares: BSD tar (bsdtar), GNU tar (gnutar) and star in archive
+creation, listing, extraction and archive-to-extracted comparision.
+Tcp prints out best time of n=$n repetitions.
+
+Tcp creates temporary archive named tcp.tar with $pax and some native
+(--seek/-no-fsync) options and extracts it to [\$3]/tcptmp/.
+If unset, third argument defaults to [\$2].
+After normal exit tcp removes tarball and extracted files.
+Tcp does not check filesystems destination directories are on for free space,
+so make sure there is enough space (a bit more than source_dir uses) for both:
+archive and extracted files.
+Do not use white space in arguments.

+.Sh NAME
+.Nm shar
+.Nd create a shell archive of files
+.Sh SYNOPSIS
+.Nm
+.Op Fl br
+.Op Fl o Ar archive-file
+.Ar
+.Sh DESCRIPTION
+The
+.Nm
+command writes a
+.Xr sh 1
+shell script which will recreate the file hierarchy specified by the command
+line operands.
+.Pp
+The
+.Nm
+command is normally used for distributing files by
+.Xr ftp 1
+or
+.Xr mail 1 .
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl b
+Use an alternative binary format.  Content of files will be uuencoded.
+This option should be used to archive binary files correctly.
+In this mode also file permissions will be stored to the archive.
+uudecode(1) is needed to extract archives created with this option.
+.It Fl o Ar archive-file
+Redirect output to
+.Ar archive-file .
+.It Fl r
+If
+.Ar file
+given on command line is a directory the entire subtree will be archived.
+Symbolic links given on command line are followed.  Other symbolic links will
+be archived as such.
+.El
+.Sh EXAMPLES
+To create a shell archive of the program
+.Xr ls 1
+and mail it to Rick:
+.Bd -literal -offset indent
+cd ls
+shar -r . \&| mail -s "ls source" rick
+.Ed
+.Pp
+To recreate the program directory:
+.Bd -literal -offset indent
+mkdir ls
+cd ls
+\&...
+<delete header lines and examine mailed archive>
+\&...
+sh archive
+.Ed
+.Sh SEE ALSO
+.Xr compress 1 ,
+.Xr mail 1 ,
+.Xr tar 1 ,
+.Xr uuencode 1 ,
+.Xr uuencode 5
+.Sh HISTORY
+The
+.Nm
+command appeared in
+.Bx 4.4 .
+This is a re-implementation based on the libarchive(3) library.
+.Sh BUGS
+The
+.Nm
+command makes no provisions for hard links.
+.Pp
+Files containing magic characters or files without a newline ('\\n') as the
+last character are not handled correctly with the default format.  Use the -b
+option for binary files.
+.Pp
+It is easy to insert trojan horses into
+.Nm
+files.
+It is strongly recommended that all shell archive files be examined
+before running them through
+.Xr sh 1 .
+Archives produced using this implementation of
+.Nm
+may be easily examined with the command:
+.Bd -literal -offset indent
+egrep -v '^[X#]' shar.file
+.Ed

+ * important differences:
+ *    * Uses less memory.  In particular, fts stores an entire directory
+ *      in memory at a time.  This package only keeps enough subdirectory
+ *      information in memory to track the traversal.  Information
+ *      about non-directories is discarded as soon as possible.
+ *    * Supports very deep logical traversals.  The fts package
+ *      uses "non-chdir" approach for logical traversals.  This
+ *      package does use a chdir approach for logical traversals
+ *      and can therefore handle pathnames much longer than
+ *      PATH_MAX.
+ *    * Supports deep physical traversals "out of the box."
+ *      Due to the memory optimizations above, there's no need to
+ *      limit dir names to 32k.

+.Sh DESCRIPTION
+.Nm
+copies files between archives and directories.
+This implementation can extract from tar, pax, cpio, zip, jar, ar,
+and ISO 9660 cdrom images and can create tar, pax, cpio, ar,
+and shar archives.
+.Pp
+The first option to
+.Nm
+is a mode indicator from the following list:
+.Bl -tag -compact -width indent
+.It Fl i
+Input.
+Read an archive from standard input (unless overriden) and extract the
+contents to disk or (if the
+.Fl t
+option is specified)
+list the contents to standard output.
+If one or more file patterns are specified, only files matching
+one of the patterns will be extracted.
+.It Fl o
+Output.
+Read a list of filenames from standard input and produce a new archive
+on standard output (unless overriden) containing the specified items.
+.It Fl p
+Pass-through.
+Read a list of filenames from standard input and copy the files to the
+specified directory.
+.El
+.Pp
+.Sh OPTIONS
+Unless specifically stated otherwise, options are applicable in
+all operating modes.

+Supported formats include:
+.Pp
+.Bl -tag -width "iso9660" -compact
+.It Ar cpio
+Synonym for
+.Ar odc .
+.It Ar newc
+The SVR4 portable cpio format.
+.It Ar odc
+The old POSIX.1 portable octet-oriented cpio format.
+.It Ar pax
+The POSIX.1 pax format, an extension of the ustar format.
+.It Ar ustar
+The POSIX.1 tar format.
+.El
+.Pp
+The default format is
+.Ar odc .
+See
+.Xr libarchive_formats 5
+for more complete information about the
+formats currently supported by the underlying
+.Xr libarchive 3
+library.
+.It Fl H Ar format
+Synonym for
+.Fl -format .
+.It Fl h , Fl -help
+Print usage information.
+.It Fl I Ar file
+Read archive from
+.Ar file .
+.It Fl i
+Input mode.
+See above for description.
+.It Fl -insecure
+(i and p mode only)
+Disable security checks during extraction or copying.
+This allows extraction via symbolic links and path names containing
+.Sq ..
+in the name.
+.It Fl J
+(o mode only)
+Compress the file with xz-compatible compression before writing it.
+In input mode, this option is ignored; xz compression is recognized
+automatically on input.
+.It Fl j
+Synonym for
+.Fl y .
+.It Fl L
+(o and p modes)
+All symbolic links will be followed.
+Normally, symbolic links are archived and copied as symbolic links.
+With this option, the target of the link will be archived or copied instead.
+.It Fl l
+(p mode only)
+Create links from the target directory to the original files,
+instead of copying.
+.It Fl lzma
+(o mode only)
+Compress the file with lzma-compatible compression before writing it.
+In input mode, this option is ignored; lzma compression is recognized
+automatically on input.
+.It Fl m
+(i and p modes)
+Set file modification time on created files to match
+those in the source.
+.It Fl n
+(i mode, only with
+.Fl t )
+Display numeric uid and gid.
+By default,
+.Nm
+displays the user and group names when they are provided in the
+archive, or looks up the user and group names in the system
+password database.
+.It Fl no-preserve-owner
+(i mode only)
+Do not attempt to restore file ownership.
+This is the default when run by non-root users.
+.It Fl O Ar file
+Write archive to
+.Ar file .
+.It Fl o
+Output mode.
+See above for description.
+.It Fl p
+Pass-through mode.
+See above for description.
+.It Fl preserve-owner
+(i mode only)
+Restore file ownership.
+This is the default when run by the root user.
+.It Fl -quiet
+Suppress unnecessary messages.
+.It Fl R Oo user Oc Ns Oo : Oc Ns Oo group Oc
+Set the owner and/or group on files in the output.
+If group is specified with no user
+(for example,
+.Fl R Ar :wheel )
+then the group will be set but not the user.
+If the user is specified with a trailing colon and no group
+(for example,
+.Fl R Ar root: )
+then the group will be set to the user's default group.
+If the user is specified with no trailing colon, then
+the user will be set but not the group.
+In
+.Fl i
+and
+.Fl p
+modes, this option can only be used by the super-user.
+(For compatibility, a period can be used in place of the colon.)
+.It Fl r
+(All modes.)
+Rename files interactively.
+For each file, a prompt is written to
+.Pa /dev/tty
+containing the name of the file and a line is read from
+.Pa /dev/tty .
+If the line read is blank, the file is skipped.
+If the line contains a single period, the file is processed normally.
+Otherwise, the line is taken to be the new name of the file.
+.It Fl t
+(i mode only)
+List the contents of the archive to stdout;
+do not restore the contents to disk.
+.It Fl u
+(i and p modes)
+Unconditionally overwrite existing files.
+Ordinarily, an older file will not overwrite a newer file on disk.
+.It Fl v
+Print the name of each file to stderr as it is processed.
+With
+.Fl t ,
+provide a detailed listing of each file.
+.It Fl -version
+Print the program version information and exit.
+.It Fl y
+(o mode only)
+Compress the archive with bzip2-compatible compression before writing it.
+In input mode, this option is ignored;
+bzip2 compression is recognized automatically on input.
+.It Fl Z
+(o mode only)
+Compress the archive with compress-compatible compression before writing it.
+In input mode, this option is ignored;
+compression is recognized automatically on input.
+.It Fl z
+(o mode only)
+Compress the archive with gzip-compatible compression before writing it.
+In input mode, this option is ignored;
+gzip compression is recognized automatically on input.
+.El
+.Sh ENVIRONMENT
+The following environment variables affect the execution of
+.Nm :
+.Bl -tag -width ".Ev BLOCKSIZE"
+.It Ev LANG
+The locale to use.
+See
+.Xr environ 7
+for more information.
+.It Ev TZ
+The timezone to use when displaying dates.
+See
+.Xr environ 7
+for more information.
+.El
+.Sh EXIT STATUS
+.Ex -std
+.Sh EXAMPLES
+The
+.Nm
+command is traditionally used to copy file heirarchies in conjunction
+with the
+.Xr find 1
+command.
+The first example here simply copies all files from
+.Pa src
+to
+.Pa dest :
+.Dl Nm find Pa src | Nm Fl pmud Pa dest
+.Pp
+By carefully selecting options to the
+.Xr find 1
+command and combining it with other standard utilities,
+it is possible to exercise very fine control over which files are copied.
+This next example copies files from
+.Pa src
+to
+.Pa dest
+that are more than 2 days old and whose names match a particular pattern:
+.Dl Nm find Pa src Fl mtime Ar +2 | Nm grep foo[bar] | Nm Fl pdmu Pa dest
+.Pp
+This example copies files from
+.Pa src
+to
+.Pa dest
+that are more than 2 days old and which contain the word
+.Do foobar Dc :
+.Dl Nm find Pa src Fl mtime Ar +2 | Nm xargs Nm grep -l foobar | Nm Fl pdmu Pa dest
+.Sh COMPATIBILITY
+The mode options i, o, and p and the options
+a, B, c, d, f, l, m, r, t, u, and v comply with SUSv2.
+.Pp
+The old POSIX.1 standard specified that only
+.Fl i ,
+.Fl o ,
+and
+.Fl p
+were interpreted as command-line options.
+Each took a single argument of a list of modifier
+characters.
+For example, the standard syntax allows
+.Fl imu
+but does not support
+.Fl miu
+or
+.Fl i Fl m Fl u ,
+since
+.Ar m
+and
+.Ar u
+are only modifiers to
+.Fl i ,
+they are not command-line options in their own right.
+The syntax supported by this implementation is backwards-compatible
+with the standard.
+For best compatibility, scripts should limit themselves to the
+standard syntax.

+.Sh STANDARDS
+There is no current POSIX standard for the cpio command; it appeared
+in
+.St -p1003.1-96
+but was dropped from
+.St -p1003.1-2001 .
+.Pp
+The cpio, ustar, and pax interchange file formats are defined by
+.St -p1003.1-2001
+for the pax command.
+.Sh HISTORY
+The original
+.Nm cpio
+and
+.Nm find
+utilities were written by Dick Haight
+while working in AT&T's Unix Support Group.
+They first appeared in 1977 in PWB/UNIX 1.0, the
+.Dq Programmer's Work Bench
+system developed for use within AT&T.
+They were first released outside of AT&T as part of System III Unix in 1981.
+As a result,
+.Nm cpio
+actually predates
+.Nm tar ,
+even though it was not well-known outside of AT&T until some time later.
+.Pp
+This is a complete re-implementation based on the
+.Xr libarchive 3
+library.
+.Sh BUGS
+The cpio archive format has several basic limitations:
+It does not store user and group names, only numbers.
+As a result, it cannot be reliably used to transfer
+files between systems with dissimilar user and group numbering.
+Older cpio formats limit the user and group numbers to
+16 or 18 bits, which is insufficient for modern systems.
+The cpio archive formats cannot support files over 4 gigabytes,
+except for the
+.Dq odc
+variant, which can support files up to 8 gigabytes.

+<p style="margin-top: 1em" valign="top"><b>DESCRIPTION</b></p>
+
+<p style="margin-left:8%;">These functions create and
+manipulate data objects that represent entries within an
+archive. You can think of a struct archive_entry as a
+heavy-duty version of struct stat: it includes everything
+from struct stat plus associated pathname, textual group and
+user names, etc. These objects are used by libarchive(3) to
+represent the metadata associated with a particular entry in
+an archive.</p>
+
+<p style="margin-left:8%; margin-top: 1em"><b>Create and
+Destroy</b> <br>
+There are functions to allocate, destroy, clear, and copy
+<i>archive_entry</i> objects:</p>
+
+<p valign="top"><b>archive_entry_clear</b>()</p>
+
+<p style="margin-left:20%;">Erases the object, resetting
+all internal fields to the same state as a newly-created
+object. This is provided to allow you to quickly recycle
+objects without thrashing the heap.</p>
+
+<p valign="top"><b>archive_entry_clone</b>()</p>
+
+<p style="margin-left:20%;">A deep copy operation; all text
+fields are duplicated.</p>
+
+<p valign="top"><b>archive_entry_free</b>()</p>
+
+<p style="margin-left:20%;">Releases the struct
+archive_entry object.</p>
+
+<p valign="top"><b>archive_entry_new</b>()</p>
+
+<p style="margin-left:20%;">Allocate and return a blank
+struct archive_entry object.</p>
+
+<p style="margin-left:8%; margin-top: 1em"><b>Set and Get
+Functions</b> <br>
+Most of the functions here set or read entries in an object.
+Such functions have one of the following forms:</p>
+
+<p valign="top"><b>archive_entry_set_XXXX</b>()</p>
+
+<p style="margin-left:20%;">Stores the provided data in the
+object. In particular, for strings, the pointer is stored,
+not the referenced string.</p>
+
+<p valign="top"><b>archive_entry_copy_XXXX</b>()</p>
+
+<p style="margin-left:20%;">As above, except that the
+referenced data is copied into the object.</p>
+
+<p valign="top"><b>archive_entry_XXXX</b>()</p>
+
+<p style="margin-left:20%;">Returns the specified data. In
+the case of strings, a const-qualified pointer to the string
+is returned.</p>
+
+<p style="margin-left:8%;">String data can be set or
+accessed as wide character strings or normal <i>char</i>
+strings. The functions that use wide character strings are
+suffixed with <b>_w</b>. Note that these are different
+representations of the same data: For example, if you store
+a narrow string and read the corresponding wide string, the
+object will transparently convert formats using the current
+locale. Similarly, if you store a wide string and then store
+a narrow string for the same data, the previously-set wide
+string will be discarded in favor of the new data.</p>
+
+<p style="margin-left:8%; margin-top: 1em">There are a few
+set/get functions that merit additional description:</p>
+
+<p valign="top"><b>archive_entry_set_link</b>()</p>
+
+<p style="margin-left:20%;">This function sets the symlink
+field if it is already set. Otherwise, it sets the hardlink
+field.</p>
+
+<p style="margin-left:8%; margin-top: 1em"><b>File
+Flags</b> <br>
+File flags are transparently converted between a bitmap
+representation and a textual format. For example, if you set
+the bitmap and ask for text, the library will build a
+canonical text format. However, if you set a text format and
+request a text format, you will get back the same text, even
+if it is ill-formed. If you need to canonicalize a textual
+flags string, you should first set the text form, then
+request the bitmap form, then use that to set the bitmap
+form. Setting the bitmap format will clear the internal text
+representation and force it to be reconstructed when you
+next request the text form.</p>
+
+<p style="margin-left:8%; margin-top: 1em">The bitmap
+format consists of two integers, one containing bits that
+should be set, the other specifying bits that should be
+cleared. Bits not mentioned in either bitmap will be
+ignored. Usually, the bitmap of bits to be cleared will be
+set to zero. In unusual circumstances, you can force a
+fully-specified set of file flags by setting the bitmap of
+flags to clear to the complement of the bitmap of flags to
+set. (This differs from fflagstostr(3), which only includes
+names for set bits.) Converting a bitmap to a textual string
+is a platform-specific operation; bits that are not
+meaningful on the current platform will be ignored.</p>
+
+<p style="margin-left:8%; margin-top: 1em">The canonical
+text format is a comma-separated list of flag names. The
+<b>archive_entry_copy_fflags_text</b>() and
+<b>archive_entry_copy_fflags_text_w</b>() functions parse
+the provided text and sets the internal bitmap values. This
+is a platform-specific operation; names that are not
+meaningful on the current platform will be ignored. The
+function returns a pointer to the start of the first name
+that was not recognized, or NULL if every name was
+recognized. Note that every name--including names that
+follow an unrecognized name--will be evaluated, and the
+bitmaps will be set to reflect every name that is
+recognized. (In particular, this differs from
+strtofflags(3), which stops parsing at the first
+unrecognized name.)</p>
+
+<p style="margin-left:8%; margin-top: 1em"><b>ACL
+Handling</b> <br>
+XXX This needs serious help. XXX</p>
+
+<p style="margin-left:8%; margin-top: 1em">An
+&lsquo;&lsquo;Access Control List&rsquo;&rsquo; (ACL) is a
+list of permissions that grant access to particular users or
+groups beyond what would normally be provided by standard
+POSIX mode bits. The ACL handling here addresses some
+deficiencies in the POSIX.1e draft 17 ACL specification. In
+particular, POSIX.1e draft 17 specifies several different
+formats, but none of those formats include both textual
+user/group names and numeric UIDs/GIDs.</p>

+
+<p style="margin-top: 1em" valign="top"><b>DESCRIPTION</b></p>
+
+<p style="margin-left:8%;">These functions provide a
+complete API for reading streaming archives. The general
+process is to first create the struct archive object, set
+options, initialize the reader, iterate over the archive
+headers and associated data, then close the archive and
+release all resources. The following summary describes the
+functions in approximately the order they would be used:</p>
+
+<p valign="top"><b>archive_read_new</b>()</p>
+
+<p style="margin-left:20%;">Allocates and initializes a
+struct archive object suitable for reading from an
+archive.</p>
+
+
+<p valign="top"><b>archive_read_support_compression_bzip2</b>(),
+<b>archive_read_support_compression_compress</b>(),
+<b>archive_read_support_compression_gzip</b>(),
+<b>archive_read_support_compression_lzma</b>(),
+<b>archive_read_support_compression_none</b>(),
+<b>archive_read_support_compression_xz</b>()</p>
+
+<p style="margin-left:20%;">Enables auto-detection code and
+decompression support for the specified compression. Returns
+<b>ARCHIVE_OK</b> if the compression is fully supported, or
+<b>ARCHIVE_WARN</b> if the compression is supported only
+through an external program. Note that decompression using
+an external program is usually slower than decompression
+through built-in libraries. Note that
+&lsquo;&lsquo;none&rsquo;&rsquo; is always enabled by
+default.</p>
+
+
+<p valign="top"><b>archive_read_support_compression_all</b>()</p>
+
+<p style="margin-left:20%;">Enables all available
+decompression filters.</p>
+
+
+<p valign="top"><b>archive_read_support_compression_program</b>()</p>
+
+<p style="margin-left:20%;">Data is fed through the
+specified external program before being dearchived. Note
+that this disables automatic detection of the compression
+format, so it makes no sense to specify this in conjunction
+with any other decompression option.</p>
+
+
+<p valign="top"><b>archive_read_support_compression_program_signature</b>()</p>
+
+<p style="margin-left:20%;">This feeds data through the
+specified external program but only if the initial bytes of
+the data match the specified signature value.</p>
+
+<p valign="top"><b>archive_read_support_format_all</b>(),
+<b>archive_read_support_format_ar</b>(),
+<b>archive_read_support_format_cpio</b>(),
+<b>archive_read_support_format_empty</b>(),
+<b>archive_read_support_format_iso9660</b>(),
+<b>archive_read_support_format_mtree</b>(),
+<b>archive_read_support_format_tar</b>(),
+<b>archive_read_support_format_zip</b>()</p>
+
+<p style="margin-left:20%;">Enables support---including
+auto-detection code---for the specified archive format. For
+example, <b>archive_read_support_format_tar</b>() enables
+support for a variety of standard tar formats, old-style
+tar, ustar, pax interchange format, and many common
+variants. For convenience,
+<b>archive_read_support_format_all</b>() enables support for
+all available formats. Only empty archives are supported by
+default.</p>
+
+
+<p valign="top"><b>archive_read_support_format_raw</b>()</p>
+
+<p style="margin-left:20%;">The
+&lsquo;&lsquo;raw&rsquo;&rsquo; format handler allows
+libarchive to be used to read arbitrary data. It treats any
+data stream as an archive with a single entry. The pathname
+of this entry is &lsquo;&lsquo;data&rsquo;&rsquo;; all other
+entry fields are unset. This is not enabled by
+<b>archive_read_support_format_all</b>() in order to avoid
+erroneous handling of damaged archives.</p>
+
+<p valign="top"><b>archive_read_set_filter_options</b>(),
+<b>archive_read_set_format_options</b>(),
+<b>archive_read_set_options</b>()</p>
+
+<p style="margin-left:20%;">Specifies options that will be
+passed to currently-registered filters (including
+decompression filters) and/or format readers. The argument
+is a comma-separated list of individual options. Individual
+options have one of the following forms:</p>
+
+<p valign="top"><i>option=value</i></p>
+
+<p style="margin-left:32%;">The option/value pair will be
+provided to every module. Modules that do not accept an
+option with this name will ignore it.</p>
+
+<p valign="top"><i>option</i></p>
+
+<p style="margin-left:32%; margin-top: 1em">The option will
+be provided to every module with a value of
+&lsquo;&lsquo;1&rsquo;&rsquo;.</p>
+
+<p valign="top"><i>!option</i></p>
+
+<p style="margin-left:32%;">The option will be provided to
+every module with a NULL value.</p>
+
+<p valign="top"><i>module:option=value</i>,
+<i>module:option</i>, <i>module:!option</i></p>
+
+<p style="margin-left:32%;">As above, but the corresponding
+option and value will be provided only to modules whose name
+matches <i>module</i>.</p>
+
+<p style="margin-left:20%;">The return value will be
+<b>ARCHIVE_OK</b> if any module accepts the option, or
+<b>ARCHIVE_WARN</b> if no module accepted the option, or
+<b>ARCHIVE_FATAL</b> if there was a fatal error while
+attempting to process the option.</p>
+
+<p style="margin-left:20%; margin-top: 1em">The currently
+supported options are:</p>
+
+<p valign="top">Format iso9660 <b><br>
+joliet</b></p>
+
+<p style="margin-left:45%; margin-top: 1em">Support Joliet
+extensions. Defaults to enabled, use <b>!joliet</b> to
+disable.</p>
+
+<p valign="top"><b>archive_read_open</b>()</p>
+
+<p style="margin-left:20%;">The same as
+<b>archive_read_open2</b>(), except that the skip callback
+is assumed to be NULL.</p>
+
+<p valign="top"><b>archive_read_open2</b>()</p>
+
+<p style="margin-left:20%;">Freeze the settings, open the
+archive, and prepare for reading entries. This is the most
+generic version of this call, which accepts four callback
+functions. Most clients will want to use
+<b>archive_read_open_filename</b>(),
+<b>archive_read_open_FILE</b>(),
+<b>archive_read_open_fd</b>(), or
+<b>archive_read_open_memory</b>() instead. The library
+invokes the client-provided functions to obtain raw bytes
+from the archive.</p>
+
+<p valign="top"><b>archive_read_open_FILE</b>()</p>
+
+<p style="margin-left:20%;">Like
+<b>archive_read_open</b>(), except that it accepts a <i>FILE
+*</i> pointer. This function should not be used with tape
+drives or other devices that require strict I/O
+blocking.</p>
+
+<p valign="top"><b>archive_read_open_fd</b>()</p>
+
+<p style="margin-left:20%;">Like
+<b>archive_read_open</b>(), except that it accepts a file
+descriptor and block size rather than a set of function
+pointers. Note that the file descriptor will not be
+automatically closed at end-of-archive. This function is
+safe for use with tape drives or other blocked devices.</p>
+
+<p valign="top"><b>archive_read_open_file</b>()</p>
+
+<p style="margin-left:20%;">This is a deprecated synonym
+for <b>archive_read_open_filename</b>().</p>
+
+<p valign="top"><b>archive_read_open_filename</b>()</p>
+
+<p style="margin-left:20%;">Like
+<b>archive_read_open</b>(), except that it accepts a simple
+filename and a block size. A NULL filename represents
+standard input. This function is safe for use with tape
+drives or other blocked devices.</p>
+
+<p valign="top"><b>archive_read_open_memory</b>()</p>
+
+<p style="margin-left:20%;">Like
+<b>archive_read_open</b>(), except that it accepts a pointer
+and size of a block of memory containing the archive
+data.</p>
+
+<p valign="top"><b>archive_read_next_header</b>()</p>
+
+<p style="margin-left:20%;">Read the header for the next
+entry and return a pointer to a struct archive_entry. This
+is a convenience wrapper around
+<b>archive_read_next_header2</b>() that reuses an internal
+struct archive_entry object for each request.</p>
+
+<p valign="top"><b>archive_read_next_header2</b>()</p>
+
+<p style="margin-left:20%;">Read the header for the next
+entry and populate the provided struct archive_entry.</p>
+
+<p valign="top"><b>archive_read_data</b>()</p>
+
+<p style="margin-left:20%;">Read data associated with the
+header just read. Internally, this is a convenience function
+that calls <b>archive_read_data_block</b>() and fills any
+gaps with nulls so that callers see a single continuous
+stream of data.</p>
+
+<p valign="top"><b>archive_read_data_block</b>()</p>
+
+<p style="margin-left:20%;">Return the next available block
+of data for this entry. Unlike <b>archive_read_data</b>(),
+the <b>archive_read_data_block</b>() function avoids copying
+data and allows you to correctly handle sparse files, as
+supported by some archive formats. The library guarantees
+that offsets will increase and that blocks will not overlap.
+Note that the blocks returned from this function can be much
+larger than the block size read from disk, due to
+compression and internal buffer optimizations.</p>
+
+<p valign="top"><b>archive_read_data_skip</b>()</p>
+
+<p style="margin-left:20%;">A convenience function that
+repeatedly calls <b>archive_read_data_block</b>() to skip
+all of the data for this archive entry.</p>
+
+<p valign="top"><b>archive_read_data_into_buffer</b>()</p>
+
+<p style="margin-left:20%;">This function is deprecated and
+will be removed. Use <b>archive_read_data</b>() instead.</p>
+
+<p valign="top"><b>archive_read_data_into_fd</b>()</p>
+
+<p style="margin-left:20%;">A convenience function that
+repeatedly calls <b>archive_read_data_block</b>() to copy
+the entire entry to the provided file descriptor.</p>
+
+<p valign="top"><b>archive_read_extract</b>(),
+<b>archive_read_extract_set_skip_file</b>()</p>
+
+<p style="margin-left:20%;">A convenience function that
+wraps the corresponding archive_write_disk(3) interfaces.
+The first call to <b>archive_read_extract</b>() creates a
+restore object using archive_write_disk_new(3) and
+archive_write_disk_set_standard_lookup(3), then
+transparently invokes archive_write_disk_set_options(3),
+archive_write_header(3), archive_write_data(3), and
+archive_write_finish_entry(3) to create the entry on disk
+and copy data into it. The <i>flags</i> argument is passed
+unmodified to archive_write_disk_set_options(3).</p>
+
+<p valign="top"><b>archive_read_extract2</b>()</p>
+
+<p style="margin-left:20%;">This is another version of
+<b>archive_read_extract</b>() that allows you to provide
+your own restore object. In particular, this allows you to
+override the standard lookup functions using
+archive_write_disk_set_group_lookup(3), and
+archive_write_disk_set_user_lookup(3). Note that
+<b>archive_read_extract2</b>() does not accept a
+<i>flags</i> argument; you should use
+<b>archive_write_disk_set_options</b>() to set the restore
+options yourself.</p>
+
+
+<p valign="top"><b>archive_read_extract_set_progress_callback</b>()</p>
+
+<p style="margin-left:20%;">Sets a pointer to a
+user-defined callback that can be used for updating progress
+displays during extraction. The progress function will be
+invoked during the extraction of large regular files. The
+progress function will be invoked with the pointer provided
+to this call. Generally, the data pointed to should include
+a reference to the archive object and the archive_entry
+object so that various statistics can be retrieved for the
+progress display.</p>
+
+<p valign="top"><b>archive_read_close</b>()</p>
+
+<p style="margin-left:20%;">Complete the archive and invoke
+the close callback.</p>
+
+<p valign="top"><b>archive_read_finish</b>()</p>
+
+<p style="margin-left:20%;">Invokes
+<b>archive_read_close</b>() if it was not invoked manually,
+then release all resources. Note: In libarchive 1.x, this
+function was declared to return <i>void</i>, which made it
+impossible to detect certain errors when
+<b>archive_read_close</b>() was invoked implicitly from this
+function. The declaration is corrected beginning with
+libarchive 2.0.</p>
+
+<p style="margin-left:8%; margin-top: 1em">Note that the
+library determines most of the relevant information about
+the archive by inspection. In particular, it automatically
+detects gzip(1) or bzip2(1) compression and transparently
+performs the appropriate decompression. It also
+automatically detects the archive format.</p>
+
+<p style="margin-left:8%; margin-top: 1em">A complete
+description of the struct archive and struct archive_entry
+objects can be found in the overview manual page for
+libarchive(3).</p>
+
+<p style="margin-top: 1em" valign="top"><b>CLIENT
+CALLBACKS</b></p>
+
+<p style="margin-left:8%;">The callback functions must
+match the following prototypes:</p>
+
+<p style="margin-left:17%; margin-top: 1em"><i>typedef
+ssize_t</i></p>
+
+
+<p valign="top"><b>archive_read_callback</b>(<i>struct&nbsp;archive&nbsp;*</i>,
+<i>void&nbsp;*client_data</i>,
+<i>const&nbsp;void&nbsp;**buffer</i>)</p>
+
+<p style="margin-left:17%; margin-top: 1em"><i>typedef
+int</i></p>
+
+
+<p valign="top"><b>archive_skip_callback</b>(<i>struct&nbsp;archive&nbsp;*</i>,
+<i>void&nbsp;*client_data</i>,
+<i>size_t&nbsp;request</i>)</p>
+
+<p style="margin-left:17%; margin-top: 1em"><i>typedef
+int</i> <b>archive_open_callback</b>(<i>struct archive
+*</i>, <i>void *client_data</i>)</p>
+
+<p style="margin-left:17%; margin-top: 1em"><i>typedef
+int</i> <b>archive_close_callback</b>(<i>struct archive
+*</i>, <i>void *client_data</i>)</p>
+
+<p style="margin-left:8%; margin-top: 1em">The open
+callback is invoked by <b>archive_open</b>(). It should
+return <b>ARCHIVE_OK</b> if the underlying file or data
+source is successfully opened. If the open fails, it should
+call <b>archive_set_error</b>() to register an error code
+and message and return <b>ARCHIVE_FATAL</b>.</p>
+
+<p style="margin-left:8%; margin-top: 1em">The read
+callback is invoked whenever the library requires raw bytes
+from the archive. The read callback should read data into a
+buffer, set the const void **buffer argument to point to the
+available data, and return a count of the number of bytes
+available. The library will invoke the read callback again
+only after it has consumed this data. The library imposes no
+constraints on the size of the data blocks returned. On
+end-of-file, the read callback should return zero. On error,
+the read callback should invoke <b>archive_set_error</b>()
+to register an error code and message and return -1.</p>
+
+<p style="margin-left:8%; margin-top: 1em">The skip
+callback is invoked when the library wants to ignore a block
+of data. The return value is the number of bytes actually
+skipped, which may differ from the request. If the callback
+cannot skip data, it should return zero. If the skip
+callback is not provided (the function pointer is NULL ),
+the library will invoke the read function instead and simply
+discard the result. A skip callback can provide significant
+performance gains when reading uncompressed archives from
+slow disk drives or other media that can skip quickly.</p>
+
+<p style="margin-left:8%; margin-top: 1em">The close
+callback is invoked by archive_close when the archive
+processing is complete. The callback should return
+<b>ARCHIVE_OK</b> on success. On failure, the callback
+should invoke <b>archive_set_error</b>() to register an
+error code and message and return <b>ARCHIVE_FATAL.</b></p>
+
+<p style="margin-top: 1em" valign="top"><b>EXAMPLE</b></p>
+
+<p style="margin-left:8%;">The following illustrates basic
+usage of the library. In this example, the callback
+functions are simply wrappers around the standard open(2),
+read(2), and close(2) system calls.</p>
+
+<p style="margin-left:17%; margin-top: 1em">void <br>

+}</p>
+
+<p style="margin-top: 1em" valign="top"><b>RETURN
+VALUES</b></p>
+
+<p style="margin-left:8%;">Most functions return zero on
+success, non-zero on error. The possible return codes
+include: <b>ARCHIVE_OK</b> (the operation succeeded),
+<b>ARCHIVE_WARN</b> (the operation succeeded but a
+non-critical error was encountered), <b>ARCHIVE_EOF</b>
+(end-of-archive was encountered), <b>ARCHIVE_RETRY</b> (the
+operation failed but can be retried), and
+<b>ARCHIVE_FATAL</b> (there was a fatal error; the archive
+should be closed immediately). Detailed error codes and
+textual descriptions are available from the
+<b>archive_errno</b>() and <b>archive_error_string</b>()
+functions.</p>
+
+
+<p style="margin-left:8%; margin-top: 1em"><b>archive_read_new</b>()
+returns a pointer to a freshly allocated struct archive
+object. It returns NULL on error.</p>
+
+
+<p style="margin-left:8%; margin-top: 1em"><b>archive_read_data</b>()
+returns a count of bytes actually read or zero at the end of
+the entry. On error, a value of <b>ARCHIVE_FATAL</b>,
+<b>ARCHIVE_WARN</b>, or <b>ARCHIVE_RETRY</b> is returned and
+an error code and textual description can be retrieved from
+the <b>archive_errno</b>() and <b>archive_error_string</b>()
+functions.</p>
+
+<p style="margin-left:8%; margin-top: 1em">The library
+expects the client callbacks to behave similarly. If there
+is an error, you can use <b>archive_set_error</b>() to set
+an appropriate error code and description, then return one
+of the non-zero values above. (Note that the value
+eventually returned to the client may not be the same; many
+errors that are not critical at the level of basic I/O can
+prevent the archive from being properly read, thus most I/O
+errors eventually cause <b>ARCHIVE_FATAL</b> to be
+returned.)</p>

+<p style="margin-top: 1em" valign="top"><b>DESCRIPTION</b></p>
+
+<p style="margin-left:8%;">These functions provide an API
+for reading information about objects on disk. In
+particular, they provide an interface for populating struct
+archive_entry objects.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>archive_read_disk_new</b>()</p>
+
+<p style="margin-left:20%;">Allocates and initializes a
+struct archive object suitable for reading object
+information from disk.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>archive_read_disk_set_symlink_logical</b>(),
+<b>archive_read_disk_set_symlink_physical</b>(),
+<b>archive_read_disk_set_symlink_hybrid</b>()</p>
+
+<p style="margin-left:20%;">This sets the mode used for
+handling symbolic links. The
+&lsquo;&lsquo;logical&rsquo;&rsquo; mode follows all
+symbolic links. The &lsquo;&lsquo;physical&rsquo;&rsquo;
+mode does not follow any symbolic links. The
+&lsquo;&lsquo;hybrid&rsquo;&rsquo; mode currently behaves
+identically to the &lsquo;&lsquo;logical&rsquo;&rsquo;
+mode.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>archive_read_disk_gname</b>(),
+<b>archive_read_disk_uname</b>()</p>
+
+<p style="margin-left:20%;">Returns a user or group name
+given a gid or uid value. By default, these always return a
+NULL string.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>archive_read_disk_set_gname_lookup</b>(),
+<b>archive_read_disk_set_uname_lookup</b>()</p>
+
+<p style="margin-left:20%;">These allow you to override the
+functions used for user and group name lookups. You may also
+provide a void * pointer to a private data structure and a
+cleanup function for that data. The cleanup function will be
+invoked when the struct archive object is destroyed or when
+new lookup functions are registered.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>archive_read_disk_set_standard_lookup</b>()</p>
+
+<p style="margin-left:20%;">This convenience function
+installs a standard set of user and group name lookup
+functions. These functions use getpwid(3) and getgrid(3) to
+convert ids to names, defaulting to NULL if the names cannot
+be looked up. These functions also implement a simple memory
+cache to reduce the number of calls to getpwid(3) and
+getgrid(3).</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>archive_read_disk_entry_from_file</b>()</p>
+
+<p style="margin-left:20%;">Populates a struct
+archive_entry object with information about a particular
+file. The archive_entry object must have already been
+created with archive_entry_new(3) and at least one of the
+source path or path fields must already be set. (If both are
+set, the source path will be used.)</p>
+
+<p style="margin-left:20%; margin-top: 1em">Information is
+read from disk using the path name from the struct
+archive_entry object. If a file descriptor is provided, some
+information will be obtained using that file descriptor, on
+platforms that support the appropriate system calls.</p>
+
+<p style="margin-left:20%; margin-top: 1em">If a pointer to
+a struct stat is provided, information from that structure
+will be used instead of reading from the disk where
+appropriate. This can provide performance benefits in
+scenarios where struct stat information has already been
+read from the disk as a side effect of some other operation.
+(For example, directory traversal libraries often provide
+this information.)</p>
+
+<p style="margin-left:20%; margin-top: 1em">Where
+necessary, user and group ids are converted to user and
+group names using the currently registered lookup functions
+above. This affects the file ownership fields and ACL values
+in the struct archive_entry object.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>archive_read_close</b>()</p>
+
+<p style="margin-left:20%;">This currently does
+nothing.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>archive_write_finish</b>()</p>
+
+<p style="margin-left:20%;">Invokes
+<b>archive_write_close</b>() if it was not invoked manually,
+then releases all resources.</p>
+
+<p style="margin-left:8%;">More information about the
+<i>struct archive</i> object and the overall design of the
+library can be found in the libarchive(3) overview.</p>
+
+<p style="margin-top: 1em" valign="top"><b>EXAMPLE</b></p>
+
+<p style="margin-left:8%;">The following illustrates basic
+usage of the library by showing how to use it to copy an

+include: <b>ARCHIVE_RETRY</b> for operations that might
+succeed if retried, <b>ARCHIVE_WARN</b> for unusual
+conditions that do not prevent further operations, and
+<b>ARCHIVE_FATAL</b> for serious errors that make remaining
+operations impossible. The archive_errno(3) and

+<p style="margin-top: 1em" valign="top"><b>HISTORY</b></p>
+
+<p style="margin-left:8%;">The <b>libarchive</b> library
+first appeared in FreeBSD&nbsp;5.3. The
+<b>archive_read_disk</b> interface was added to
+<b>libarchive 2.6</b> and first appeared in
+FreeBSD&nbsp;8.0.</p>
+
+<p style="margin-top: 1em" valign="top"><b>AUTHORS</b></p>
+
+<p style="margin-left:8%;">The <b>libarchive</b> library
+was written by Tim Kientzle
+&lang;kientzle@freebsd.org&rang;.</p>
+
+<p style="margin-top: 1em" valign="top"><b>BUGS</b></p>
+
+<p style="margin-left:8%;">The
+&lsquo;&lsquo;standard&rsquo;&rsquo; user name and group
+name lookup functions are not the defaults because
+getgrid(3) and getpwid(3) are sometimes too large for
+particular applications. The current design allows the
+application author to use a more compact implementation when
+appropriate.</p>
+
+<p style="margin-left:8%; margin-top: 1em">The full list of
+metadata read from disk by
+<b>archive_read_disk_entry_from_file</b>() is necessarily
+system-dependent.</p>
+
+<p style="margin-left:8%; margin-top: 1em">The
+<b>archive_read_disk_entry_from_file</b>() function reads as
+much information as it can from disk. Some method should be
+provided to limit this so that clients who do not need ACLs,
+for instance, can avoid the extra work needed to look up
+such information.</p>
+
+<p style="margin-left:8%; margin-top: 1em">This API should
+provide a set of methods for walking a directory tree. That
+would make it a direct parallel of the archive_read(3) API.
+When such methods are implemented, the
+&lsquo;&lsquo;hybrid&rsquo;&rsquo; symbolic link mode will
+make sense.</p>

+
+<p style="margin-left:8%;">These functions provide access
+to various information about the struct archive object used
+in the libarchive(3) library.</p>
+
+<p valign="top"><b>archive_clear_error</b>()</p>
+
+<p style="margin-left:20%;">Clears any error information
+left over from a previous call. Not generally used in client
+code.</p>
+
+<p valign="top"><b>archive_compression</b>()</p>
+
+<p style="margin-left:20%;">Returns a numeric code
+indicating the current compression. This value is set by
+<b>archive_read_open</b>().</p>
+
+<p valign="top"><b>archive_compression_name</b>()</p>
+
+<p style="margin-left:20%;">Returns a text description of
+the current compression suitable for display.</p>
+
+<p valign="top"><b>archive_copy_error</b>()</p>
+
+<p style="margin-left:20%;">Copies error information from
+one archive to another.</p>
+
+<p valign="top"><b>archive_errno</b>()</p>
+
+<p style="margin-left:20%;">Returns a numeric error code
+(see errno(2)) indicating the reason for the most recent
+error return.</p>
+
+<p valign="top"><b>archive_error_string</b>()</p>
+
+<p style="margin-left:20%;">Returns a textual error message
+suitable for display. The error message here is usually more
+specific than that obtained from passing the result of
+<b>archive_errno</b>() to strerror(3).</p>
+
+<p valign="top"><b>archive_file_count</b>()</p>
+
+<p style="margin-left:20%;">Returns a count of the number
+of files processed by this archive object. The count is
+incremented by calls to archive_write_header or
+archive_read_next_header.</p>
+
+<p valign="top"><b>archive_format</b>()</p>
+
+<p style="margin-left:20%;">Returns a numeric code
+indicating the format of the current archive entry. This
+value is set by a successful call to
+<b>archive_read_next_header</b>(). Note that it is common
+for this value to change from entry to entry. For example, a
+tar archive might have several entries that utilize GNU tar
+extensions and several entries that do not. These entries
+will have different format codes.</p>
+
+<p valign="top"><b>archive_format_name</b>()</p>
+
+<p style="margin-left:20%;">A textual description of the
+format of the current entry.</p>
+
+<p valign="top"><b>archive_set_error</b>()</p>
+
+<p style="margin-left:20%;">Sets the numeric error code and
+error description that will be returned by
+<b>archive_errno</b>() and <b>archive_error_string</b>().
+This function should be used within I/O callbacks to set
+system-specific error codes and error descriptions. This
+function accepts a printf-like format string and arguments.
+However, you should be careful to use only the following
+printf format specifiers: &lsquo;&lsquo;%c&rsquo;&rsquo;,
+&lsquo;&lsquo;%d&rsquo;&rsquo;,
+&lsquo;&lsquo;%jd&rsquo;&rsquo;,
+&lsquo;&lsquo;%jo&rsquo;&rsquo;,

+&lsquo;&lsquo;%u&rsquo;&rsquo;,
+&lsquo;&lsquo;%s&rsquo;&rsquo;,
+&lsquo;&lsquo;%x&rsquo;&rsquo;,
+&lsquo;&lsquo;%%&rsquo;&rsquo;. Field-width specifiers and
+other printf features are not uniformly supported and should
+not be used.</p>

+
+<p style="margin-top: 1em" valign="top"><b>DESCRIPTION</b></p>
+
+<p style="margin-left:8%;">These functions provide a
+complete API for creating streaming archive files. The
+general process is to first create the struct archive
+object, set any desired options, initialize the archive,
+append entries, then close the archive and release all
+resources. The following summary describes the functions in
+approximately the order they are ordinarily used:</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>archive_write_new</b>()</p>
+
+<p style="margin-left:20%;">Allocates and initializes a
+struct archive object suitable for writing a tar
+archive.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>archive_write_set_bytes_per_block</b>()</p>
+
+<p style="margin-left:20%;">Sets the block size used for
+writing the archive data. Every call to the write callback
+function, except possibly the last one, will use this value
+for the length. The third parameter is a boolean that
+specifies whether or not the final block written will be
+padded to the full block size. If it is zero, the last block
+will not be padded. If it is non-zero, padding will be added
+both before and after compression. The default is to use a
+block size of 10240 bytes and to pad the last block. Note
+that a block size of zero will suppress internal blocking
+and cause writes to be sent directly to the write callback
+as they occur.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>archive_write_get_bytes_per_block</b>()</p>
+
+<p style="margin-left:20%;">Retrieve the block size to be
+used for writing. A value of -1 here indicates that the

+that internal blocking is suppressed.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>archive_write_set_bytes_in_last_block</b>()</p>
+
+<p style="margin-left:20%;">Sets the block size used for
+writing the last block. If this value is zero, the last
+block will be padded to the same size as the other blocks.
+Otherwise, the final block will be padded to a multiple of
+this size. In particular, setting it to 1 will cause the
+final block to not be padded. For compressed output, any
+padding generated by this option is applied only after the
+compression. The uncompressed data is always unpadded. The
+default is to pad the last block to the full block size
+(note that <b>archive_write_open_filename</b>() will set
+this based on the file type). Unlike the other
+&lsquo;&lsquo;set&rsquo;&rsquo; functions, this function can
+be called after the archive is opened.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>archive_write_get_bytes_in_last_block</b>()</p>
+
+<p style="margin-left:20%;">Retrieve the currently-set
+value for last block size. A value of -1 here indicates that
+the library should use default values.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>archive_write_set_format_cpio</b>(),

+<b>archive_write_set_format_shar_binary</b>(),
+<b>archive_write_set_format_ustar</b>()</p>
+
+<p style="margin-left:20%;">Sets the format that will be
+used for the archive. The library can write POSIX
+octet-oriented cpio format archives, POSIX-standard
+&lsquo;&lsquo;pax interchange&rsquo;&rsquo; format archives,
+traditional &lsquo;&lsquo;shar&rsquo;&rsquo; archives,
+enhanced &lsquo;&lsquo;binary&rsquo;&rsquo; shar archives
+that store a variety of file attributes and handle binary
+files, and POSIX-standard &lsquo;&lsquo;ustar&rsquo;&rsquo;
+archives. The pax interchange format is a
+backwards-compatible tar format that adds key/value
+attributes to each entry and supports arbitrary filenames,
+linknames, uids, sizes, etc. &lsquo;&lsquo;Restricted pax
+interchange format&rsquo;&rsquo; is the library default;
+this is the same as pax format, but suppresses the pax
+extended header for most normal files. In most cases, this
+will result in ordinary ustar archives.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>archive_write_set_compression_bzip2</b>(),
+<b>archive_write_set_compression_compress</b>(),
+<b>archive_write_set_compression_gzip</b>(),
+<b>archive_write_set_compression_none</b>()</p>
+
+<p style="margin-left:20%;">The resulting archive will be
+compressed as specified. Note that the compressed output is
+always properly blocked.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>archive_write_set_compression_program</b>()</p>
+
+<p style="margin-left:20%;">The archive will be fed into

+
+<p style="margin-top: 1em" valign="top"><b>archive_write_set_compressor_options</b>(),
+<b>archive_write_set_format_options</b>(),
+<b>archive_write_set_options</b>()</p>
+
+<p style="margin-left:20%;">Specifies options that will be

+writer. The argument is a comma-separated list of individual
+options. Individual options have one of the following
+forms:</p>
+
+<p valign="top"><i>option=value</i></p>
+
+<p style="margin-left:32%;">The option/value pair will be

+
+<p valign="top"><i>option</i></p>
+
+<p style="margin-left:32%; margin-top: 1em">The option will

+
+<p style="margin-left:20%;">The return value will be
+<b>ARCHIVE_OK</b> if any module accepts the option, or

+<b>ARCHIVE_FATAL</b> if there was a fatal error while
+attempting to process the option.</p>
+
+<p style="margin-left:20%; margin-top: 1em">The currently

+
+<p valign="top">Compressor gzip <b><br>

+
+<p style="margin-left:45%;">The value is interpreted as a

+
+<p valign="top"><b>indent</b></p>
+
+<p style="margin-left:45%; margin-top: 1em">XXX needs
+explanation XXX</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>archive_write_open</b>()</p>
+
+<p style="margin-left:20%;">Freeze the settings, open the
+archive, and prepare for writing entries. This is the most
+generic form of this function, which accepts pointers to
+three callback functions which will be invoked by the
+compression layer to write the constructed archive.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>archive_write_open_fd</b>()</p>
+
+<p style="margin-left:20%;">A convenience form of
+<b>archive_write_open</b>() that accepts a file descriptor.
+The <b>archive_write_open_fd</b>() function is safe for use
+with tape drives or other block-oriented devices.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>archive_write_open_FILE</b>()</p>
+
+<p style="margin-left:20%;">A convenience form of
+<b>archive_write_open</b>() that accepts a <i>FILE *</i>
+pointer. Note that <b>archive_write_open_FILE</b>() is not
+safe for writing to tape drives or other devices that
+require correct blocking.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>archive_write_open_file</b>()</p>
+
+<p style="margin-left:20%;">A deprecated synonym for
+<b>archive_write_open_filename</b>().</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>archive_write_open_filename</b>()</p>
+
+<p style="margin-left:20%;">A convenience form of
+<b>archive_write_open</b>() that accepts a filename. A NULL
+argument indicates that the output should be written to
+standard output; an argument of
+&lsquo;&lsquo;-&rsquo;&rsquo; will open a file with that
+name. If you have not invoked
+<b>archive_write_set_bytes_in_last_block</b>(), then
+<b>archive_write_open_filename</b>() will adjust the
+last-block padding depending on the file: it will enable
+padding when writing to standard output or to a character or
+block device node, it will disable padding otherwise. You
+can override this by manually invoking
+<b>archive_write_set_bytes_in_last_block</b>() before
+calling <b>archive_write_open</b>(). The
+<b>archive_write_open_filename</b>() function is safe for
+use with tape drives or other block-oriented devices.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>archive_write_open_memory</b>()</p>
+
+<p style="margin-left:20%;">A convenience form of
+<b>archive_write_open</b>() that accepts a pointer to a
+block of memory that will receive the archive. The final
+<i>size_t *</i> argument points to a variable that will be
+updated after each write to reflect how much of the buffer
+is currently in use. You should be careful to ensure that
+this variable remains allocated until after the archive is
+closed.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>archive_write_header</b>()</p>
+
+<p style="margin-left:20%;">Build and write a header using
+the data in the provided struct archive_entry structure. See
+archive_entry(3) for information on creating and populating
+struct archive_entry objects.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>archive_write_data</b>()</p>
+
+<p style="margin-left:20%;">Write data corresponding to the
+header just written. Returns number of bytes written or -1
+on error.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>archive_write_finish_entry</b>()</p>
+
+<p style="margin-left:20%;">Close out the entry just
+written. In particular, this writes out the final padding
+required by some formats. Ordinarily, clients never need to
+call this, as it is called automatically by
+<b>archive_write_next_header</b>() and
+<b>archive_write_close</b>() as needed.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>archive_write_close</b>()</p>
+
+<p style="margin-left:20%;">Complete the archive and invoke
+the close callback.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>archive_write_finish</b>()</p>
+
+<p style="margin-left:20%;">Invokes
+<b>archive_write_close</b>() if it was not invoked manually,
+then releases all resources. Note that this function was
+declared to return <i>void</i> in libarchive 1.x, which made
+it impossible to detect errors when
+<b>archive_write_close</b>() was invoked implicitly from
+this function. This is corrected beginning with libarchive
+2.0.</p>
+
+<p style="margin-left:8%;">More information about the
+<i>struct archive</i> object and the overall design of the
+library can be found in the libarchive(3) overview.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>IMPLEMENTATION</b></p>
+
+<p style="margin-left:8%;">Compression support is built-in
+to libarchive, which uses zlib and bzlib to handle gzip and
+bzip2 compression, respectively.</p>
+
+<p style="margin-top: 1em" valign="top"><b>CLIENT
+CALLBACKS</b></p>
+
+<p style="margin-left:8%;">To use this library, you will
+need to define and register callback functions that will be
+invoked to write data to the resulting archive. These
+functions are registered by calling
+<b>archive_write_open</b>():</p>
+
+<p style="margin-left:17%; margin-top: 1em"><i>typedef
+int</i> <b>archive_open_callback</b>(<i>struct archive
+*</i>, <i>void *client_data</i>)</p>
+
+<p style="margin-left:8%; margin-top: 1em">The open
+callback is invoked by <b>archive_write_open</b>(). It
+should return <b>ARCHIVE_OK</b> if the underlying file or
+data source is successfully opened. If the open fails, it
+should call <b>archive_set_error</b>() to register an error
+code and message and return <b>ARCHIVE_FATAL</b>.</p>
+
+<p style="margin-left:17%; margin-top: 1em"><i>typedef
+ssize_t</i></p>
+
+
+<p valign="top"><b>archive_write_callback</b>(<i>struct&nbsp;archive&nbsp;*</i>,
+<i>void&nbsp;*client_data</i>,
+<i>const&nbsp;void&nbsp;*buffer</i>,
+<i>size_t&nbsp;length</i>)</p>
+
+<p style="margin-left:8%; margin-top: 1em">The write
+callback is invoked whenever the library needs to write raw
+bytes to the archive. For correct blocking, each call to the
+write callback function should translate into a single
+write(2) system call. This is especially critical when
+writing archives to tape drives. On success, the write
+callback should return the number of bytes actually written.
+On error, the callback should invoke
+<b>archive_set_error</b>() to register an error code and
+message and return -1.</p>
+
+<p style="margin-left:17%; margin-top: 1em"><i>typedef
+int</i> <b>archive_close_callback</b>(<i>struct archive
+*</i>, <i>void *client_data</i>)</p>
+
+<p style="margin-left:8%; margin-top: 1em">The close
+callback is invoked by archive_close when the archive
+processing is complete. The callback should return
+<b>ARCHIVE_OK</b> on success. On failure, the callback
+should invoke <b>archive_set_error</b>() to register an
+error code and message and return <b>ARCHIVE_FATAL.</b></p>
+
+<p style="margin-top: 1em" valign="top"><b>EXAMPLE</b></p>
+
+<p style="margin-left:8%;">The following sketch illustrates
+basic usage of the library. In this example, the callback
+functions are simply wrappers around the standard open(2),
+write(2), and close(2) system calls.</p>

+<p style="margin-top: 1em" valign="top"><b>HISTORY</b></p>
+
+<p style="margin-left:8%;">The <b>libarchive</b> library
+first appeared in FreeBSD&nbsp;5.3.</p>
+
+<p style="margin-top: 1em" valign="top"><b>AUTHORS</b></p>
+
+<p style="margin-left:8%;">The <b>libarchive</b> library
+was written by Tim Kientzle
+&lang;kientzle@acm.org&rang;.</p>
+
+<p style="margin-top: 1em" valign="top"><b>BUGS</b></p>
+
+<p style="margin-left:8%;">There are many peculiar bugs in
+historic tar implementations that may cause certain programs
+to reject archives written by this library. For example,
+several historic implementations calculated header checksums
+incorrectly and will thus reject valid archives; GNU tar
+does not fully support pax interchange format; some old tar
+implementations required specific field terminations.</p>
+
+<p style="margin-left:8%; margin-top: 1em">The default pax
+interchange format eliminates most of the historic tar
+limitations and provides a generic key/value attribute
+facility for vendor-defined extensions. One oversight in
+POSIX is the failure to provide a standard attribute for
+large device numbers. This library uses
+&lsquo;&lsquo;SCHILY.devminor&rsquo;&rsquo; and
+&lsquo;&lsquo;SCHILY.devmajor&rsquo;&rsquo; for device
+numbers that exceed the range supported by the
+backwards-compatible ustar header. These keys are compatible
+with Joerg Schilling&rsquo;s <b>star</b> archiver. Other
+implementations may not recognize these keys and will thus
+be unable to correctly restore device nodes with large
+device numbers from archives created by this library.</p>

+
+
+<p style="margin-top: 1em" valign="top"><b>DESCRIPTION</b></p>
+
+<p style="margin-left:8%;">These functions provide a
+complete API for creating objects on disk from struct
+archive_entry descriptions. They are most naturally used
+when extracting objects from an archive using the
+<b>archive_read</b>() interface. The general process is to
+read struct archive_entry objects from an archive, then
+write those objects to a struct archive object created using
+the <b>archive_write_disk</b>() family functions. This
+interface is deliberately very similar to the
+<b>archive_write</b>() interface used to write objects to a
+streaming archive.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>archive_write_disk_new</b>()</p>
+
+<p style="margin-left:20%;">Allocates and initializes a
+struct archive object suitable for writing objects to
+disk.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>archive_write_disk_set_skip_file</b>()</p>
+
+<p style="margin-left:20%;">Records the device and inode
+numbers of a file that should not be overwritten. This is
+typically used to ensure that an extraction process does not
+overwrite the archive from which objects are being read.
+This capability is technically unnecessary but can be a
+significant performance optimization in practice.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>archive_write_disk_set_options</b>()</p>
+
+<p style="margin-left:20%;">The options field consists of a
+bitwise OR of one or more of the following values:</p>
+
+<p valign="top"><b>ARCHIVE_EXTRACT_OWNER</b></p>
+
+<p style="margin-left:32%;">The user and group IDs should
+be set on the restored file. By default, the user and group
+IDs are not restored.</p>
+
+<p valign="top"><b>ARCHIVE_EXTRACT_PERM</b></p>
+
+<p style="margin-left:32%;">Full permissions (including
+SGID, SUID, and sticky bits) should be restored exactly as
+specified, without obeying the current umask. Note that SUID
+and SGID bits can only be restored if the user and group ID
+of the object on disk are correct. If
+<b>ARCHIVE_EXTRACT_OWNER</b> is not specified, then SUID and
+SGID bits will only be restored if the default user and
+group IDs of newly-created objects on disk happen to match
+those specified in the archive entry. By default, only basic
+permissions are restored, and umask is obeyed.</p>
+
+<p valign="top"><b>ARCHIVE_EXTRACT_TIME</b></p>
+
+<p style="margin-left:32%;">The timestamps (mtime, ctime,
+and atime) should be restored. By default, they are ignored.
+Note that restoring of atime is not currently supported.</p>
+
+<p valign="top"><b>ARCHIVE_EXTRACT_NO_OVERWRITE</b></p>
+
+<p style="margin-left:32%;">Existing files on disk will not
+be overwritten. By default, existing regular files are
+truncated and overwritten; existing directories will have
+their permissions updated; other pre-existing objects are
+unlinked and recreated from scratch.</p>
+
+<p valign="top"><b>ARCHIVE_EXTRACT_UNLINK</b></p>
+
+<p style="margin-left:32%;">Existing files on disk will be
+unlinked before any attempt to create them. In some cases,
+this can prove to be a significant performance improvement.
+By default, existing files are truncated and rewritten, but
+the file is not recreated. In particular, the default
+behavior does not break existing hard links.</p>
+
+<p valign="top"><b>ARCHIVE_EXTRACT_ACL</b></p>
+
+<p style="margin-left:32%;">Attempt to restore ACLs. By
+default, extended ACLs are ignored.</p>
+
+<p valign="top"><b>ARCHIVE_EXTRACT_FFLAGS</b></p>
+
+<p style="margin-left:32%;">Attempt to restore extended
+file flags. By default, file flags are ignored.</p>
+
+<p valign="top"><b>ARCHIVE_EXTRACT_XATTR</b></p>
+
+<p style="margin-left:32%;">Attempt to restore POSIX.1e
+extended attributes. By default, they are ignored.</p>
+
+<p valign="top"><b>ARCHIVE_EXTRACT_SECURE_SYMLINKS</b></p>
+
+<p style="margin-left:32%;">Refuse to extract any object
+whose final location would be altered by a symlink on disk.
+This is intended to help guard against a variety of mischief
+caused by archives that (deliberately or otherwise) extract
+files outside of the current directory. The default is not
+to perform this check. If <b>ARCHIVE_EXTRACT_UNLINK</b> is
+specified together with this option, the library will remove
+any intermediate symlinks it finds and return an error only
+if such symlink could not be removed.</p>
+
+<p valign="top"><b>ARCHIVE_EXTRACT_SECURE_NODOTDOT</b></p>
+
+<p style="margin-left:32%;">Refuse to extract a path that
+contains a <i>..</i> element anywhere within it. The default
+is to not refuse such paths. Note that paths ending in
+<i>..</i> always cause an error, regardless of this
+flag.</p>
+
+<p valign="top"><b>ARCHIVE_EXTRACT_SPARSE</b></p>
+
+<p style="margin-left:32%;">Scan data for blocks of NUL
+bytes and try to recreate them with holes. This results in
+sparse files, independent of whether the archive format
+supports or uses them.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>archive_write_disk_set_group_lookup</b>(),
+<b>archive_write_disk_set_user_lookup</b>()</p>
+
+<p style="margin-left:20%;">The struct archive_entry
+objects contain both names and ids that can be used to
+identify users and groups. These names and ids describe the
+ownership of the file itself and also appear in ACL lists.
+By default, the library uses the ids and ignores the names,
+but this can be overridden by registering user and group
+lookup functions. To register, you must provide a lookup
+function which accepts both a name and id and returns a
+suitable id. You may also provide a void * pointer to a
+private data structure and a cleanup function for that data.
+The cleanup function will be invoked when the struct archive
+object is destroyed.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>archive_write_disk_set_standard_lookup</b>()</p>
+
+<p style="margin-left:20%;">This convenience function
+installs a standard set of user and group lookup functions.
+These functions use getpwnam(3) and getgrnam(3) to convert
+names to ids, defaulting to the ids if the names cannot be
+looked up. These functions also implement a simple memory
+cache to reduce the number of calls to getpwnam(3) and
+getgrnam(3).</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>archive_write_header</b>()</p>
+
+<p style="margin-left:20%;">Build and write a header using
+the data in the provided struct archive_entry structure. See
+archive_entry(3) for information on creating and populating
+struct archive_entry objects.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>archive_write_data</b>()</p>
+
+<p style="margin-left:20%;">Write data corresponding to the
+header just written. Returns number of bytes written or -1
+on error.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>archive_write_finish_entry</b>()</p>
+
+<p style="margin-left:20%;">Close out the entry just
+written. Ordinarily, clients never need to call this, as it
+is called automatically by
+<b>archive_write_next_header</b>() and
+<b>archive_write_close</b>() as needed.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>archive_write_close</b>()</p>
+
+<p style="margin-left:20%;">Set any attributes that could
+not be set during the initial restore. For example,
+directory timestamps are not restored initially because
+restoring a subsequent file would alter that timestamp.
+Similarly, non-writable directories are initially created
+with write permissions (so that their contents can be
+restored). The <b>archive_write_disk_new</b> library
+maintains a list of all such deferred attributes and sets
+them when this function is invoked.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>archive_write_finish</b>()</p>
+
+<p style="margin-left:20%;">Invokes
+<b>archive_write_close</b>() if it was not invoked manually,
+then releases all resources.</p>
+
+<p style="margin-left:8%;">More information about the
+<i>struct archive</i> object and the overall design of the
+library can be found in the libarchive(3) overview. Many of
+these functions are also documented under
+archive_write(3).</p>
+
+<p style="margin-top: 1em" valign="top"><b>RETURN
+VALUES</b></p>
+
+<p style="margin-left:8%;">Most functions return
+<b>ARCHIVE_OK</b> (zero) on success, or one of several
+non-zero error codes for errors. Specific error codes
+include: <b>ARCHIVE_RETRY</b> for operations that might
+succeed if retried, <b>ARCHIVE_WARN</b> for unusual
+conditions that do not prevent further operations, and
+<b>ARCHIVE_FATAL</b> for serious errors that make remaining
+operations impossible. The <b>archive_errno</b>() and
+<b>archive_error_string</b>() functions can be used to
+retrieve an appropriate error code and a textual error
+message.</p>
+
+
+<p style="margin-left:8%; margin-top: 1em"><b>archive_write_disk_new</b>()
+returns a pointer to a newly-allocated struct archive
+object.</p>
+
+
+<p style="margin-left:8%; margin-top: 1em"><b>archive_write_data</b>()
+returns a count of the number of bytes actually written. On
+error, -1 is returned and the <b>archive_errno</b>() and
+<b>archive_error_string</b>() functions will return
+appropriate values.</p>

+<p style="margin-top: 1em" valign="top"><b>HISTORY</b></p>
+
+<p style="margin-left:8%;">The <b>libarchive</b> library
+first appeared in FreeBSD&nbsp;5.3. The
+<b>archive_write_disk</b> interface was added to
+<b>libarchive 2.0</b> and first appeared in
+FreeBSD&nbsp;6.3.</p>
+
+<p style="margin-top: 1em" valign="top"><b>AUTHORS</b></p>
+
+<p style="margin-left:8%;">The <b>libarchive</b> library
+was written by Tim Kientzle
+&lang;kientzle@acm.org&rang;.</p>
+
+<p style="margin-top: 1em" valign="top"><b>BUGS</b></p>
+
+<p style="margin-left:8%;">Directories are actually
+extracted in two distinct phases. Directories are created
+during <b>archive_write_header</b>(), but final permissions
+are not set until <b>archive_write_close</b>(). This
+separation is necessary to correctly handle borderline cases
+such as a non-writable directory containing files, but can
+cause unexpected results. In particular, directory
+permissions are not fully restored until the archive is
+closed. If you use chdir(2) to change the current directory
+between calls to <b>archive_read_extract</b>() or before
+calling <b>archive_read_close</b>(), you may confuse the
+permission-setting logic with the result that directory
+permissions are restored incorrectly.</p>
+
+<p style="margin-left:8%; margin-top: 1em">The library
+attempts to create objects with filenames longer than
+<b>PATH_MAX</b> by creating prefixes of the full path and
+changing the current directory. Currently, this logic is
+limited in scope; the fixup pass does not work correctly for
+such objects and the symlink security check option disables
+the support for very long pathnames.</p>
+
+<p style="margin-left:8%; margin-top: 1em">Restoring the
+path <i>aa/../bb</i> does create each intermediate
+directory. In particular, the directory <i>aa</i> is created
+as well as the final object <i>bb</i>. In theory, this can
+be exploited to create an entire directory heirarchy with a
+single request. Of course, this does not work if the
+<b>ARCHIVE_EXTRACT_NODOTDOT</b> option is specified.</p>
+
+<p style="margin-left:8%; margin-top: 1em">Implicit
+directories are always created obeying the current umask.
+Explicit objects are created obeying the current umask
+unless <b>ARCHIVE_EXTRACT_PERM</b> is specified, in which
+case they current umask is ignored.</p>
+
+<p style="margin-left:8%; margin-top: 1em">SGID and SUID
+bits are restored only if the correct user and group could
+be set. If <b>ARCHIVE_EXTRACT_OWNER</b> is not specified,
+then no attempt is made to set the ownership. In this case,
+SGID and SUID bits are restored only if the user and group
+of the final object happen to match those specified in the
+entry.</p>
+
+<p style="margin-left:8%; margin-top: 1em">The
+&lsquo;&lsquo;standard&rsquo;&rsquo; user-id and group-id
+lookup functions are not the defaults because getgrnam(3)
+and getpwnam(3) are sometimes too large for particular
+applications. The current design allows the application
+author to use a more compact implementation when
+appropriate.</p>
+
+<p style="margin-left:8%; margin-top: 1em">There should be
+a corresponding <b>archive_read_disk</b> interface that
+walks a directory heirarchy and returns archive entry
+objects.</p>

+
+
+<p style="margin-top: 1em" valign="top"><b>ENVIRONMENT</b></p>
+
+<p style="margin-left:8%;">The following environment
+variables affect the execution of <b>cpio</b>:</p>
+
+<p style="margin-top: 1em" valign="top">LANG</p>
+
+<p style="margin-left:25%; margin-top: 1em">The locale to
+use. See environ(7) for more information.</p>
+
+<p style="margin-top: 1em" valign="top">TZ</p>
+
+<p style="margin-left:25%; margin-top: 1em">The timezone to
+use when displaying dates. See environ(7) for more
+information.</p>
+
+<p style="margin-top: 1em" valign="top"><b>EXIT
+STATUS</b></p>
+
+<p style="margin-left:8%;">The <b>cpio</b> utility
+exits&nbsp;0 on success, and&nbsp;&gt;0 if an error
+occurs.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>EXAMPLES</b></p>
+
+<p style="margin-left:8%;">The <b>cpio</b> command is
+traditionally used to copy file heirarchies in conjunction
+with the find(1) command. The first example here simply
+copies all files from <i>src</i> to <i>dest</i>:</p>
+
+<p style="margin-left:17%;"><b>find</b> <i>src</i> |
+<b>cpio &minus;pmud</b> <i>dest</i></p>
+
+<p style="margin-left:8%; margin-top: 1em">By carefully
+selecting options to the find(1) command and combining it
+with other standard utilities, it is possible to exercise
+very fine control over which files are copied. This next
+example copies files from <i>src</i> to <i>dest</i> that are
+more than 2 days old and whose names match a particular
+pattern:</p>
+
+<p style="margin-left:17%;"><b>find</b> <i>src</i>
+<b>&minus;mtime</b> <i>+2</i> | <b>grep foo[bar]</b> |
+<b>cpio &minus;pdmu</b> <i>dest</i></p>
+
+<p style="margin-left:8%; margin-top: 1em">This example
+copies files from <i>src</i> to <i>dest</i> that are more
+than 2 days old and which contain the word
+&lsquo;&lsquo;</p>
+
+<p valign="top">foobar &rsquo;&rsquo;:</p>
+
+<p style="margin-left:17%;"><b>find</b> <i>src</i>
+<b>&minus;mtime</b> <i>+2</i> | <b>xargs grep -l foobar</b>
+| <b>cpio &minus;pdmu</b> <i>dest</i></p>
+
+
+<p style="margin-top: 1em" valign="top"><b>COMPATIBILITY</b></p>
+
+<p style="margin-left:8%;">The mode options i, o, and p and
+the options a, B, c, d, f, l, m, r, t, u, and v comply with
+SUSv2.</p>
+
+<p style="margin-left:8%; margin-top: 1em">The old POSIX.1
+standard specified that only <b>&minus;i</b>,
+<b>&minus;o</b>, and <b>&minus;p</b> were interpreted as
+command-line options. Each took a single argument of a list
+of modifier characters. For example, the standard syntax
+allows <b>&minus;imu</b> but does not support
+<b>&minus;miu</b> or <b>&minus;i &minus;m &minus;u</b>,
+since <i>m</i> and <i>u</i> are only modifiers to
+<b>&minus;i</b>, they are not command-line options in their
+own right. The syntax supported by this implementation is
+backwards-compatible with the standard. For best
+compatibility, scripts should limit themselves to the
+standard syntax.</p>
+
+<p style="margin-top: 1em" valign="top"><b>SEE ALSO</b></p>
+
+<p style="margin-left:8%;">bzip2(1), tar(1), gzip(1),
+mt(1), pax(1), libarchive(3), cpio(5),
+libarchive-formats(5), tar(5)</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>STANDARDS</b></p>
+
+<p style="margin-left:8%;">There is no current POSIX
+standard for the cpio command; it appeared in ISO/IEC
+9945-1:1996 (&lsquo;&lsquo;POSIX.1&rsquo;&rsquo;) but was
+dropped from IEEE Std 1003.1-2001
+(&lsquo;&lsquo;POSIX.1&rsquo;&rsquo;).</p>
+
+<p style="margin-left:8%; margin-top: 1em">The cpio, ustar,
+and pax interchange file formats are defined by IEEE Std
+1003.1-2001 (&lsquo;&lsquo;POSIX.1&rsquo;&rsquo;) for the
+pax command.</p>
+
+<p style="margin-top: 1em" valign="top"><b>HISTORY</b></p>
+
+<p style="margin-left:8%;">The original <b>cpio</b> and
+<b>find</b> utilities were written by Dick Haight while
+working in AT&amp;T&rsquo;s Unix Support Group. They first
+appeared in 1977 in PWB/UNIX 1.0, the
+&lsquo;&lsquo;Programmer&rsquo;s Work Bench&rsquo;&rsquo;
+system developed for use within AT&amp;T. They were first
+released outside of AT&amp;T as part of System III Unix in
+1981. As a result, <b>cpio</b> actually predates <b>tar</b>,
+even though it was not well-known outside of AT&amp;T until
+some time later.</p>
+
+<p style="margin-left:8%; margin-top: 1em">This is a
+complete re-implementation based on the libarchive(3)
+library.</p>
+
+<p style="margin-top: 1em" valign="top"><b>BUGS</b></p>
+
+<p style="margin-left:8%;">The cpio archive format has
+several basic limitations: It does not store user and group
+names, only numbers. As a result, it cannot be reliably used
+to transfer files between systems with dissimilar user and
+group numbering. Older cpio formats limit the user and group
+numbers to 16 or 18 bits, which is insufficient for modern
+systems. The cpio archive formats cannot support files over
+4 gigabytes, except for the &lsquo;&lsquo;odc&rsquo;&rsquo;
+variant, which can support files up to 8 gigabytes.</p>

+<p style="margin-top: 1em" valign="top"><b>DESCRIPTION</b></p>
+
+<p style="margin-left:8%;"><b>tar</b> creates and
+manipulates streaming archive files. This implementation can
+extract from tar, pax, cpio, zip, jar, ar, and ISO 9660
+cdrom images and can create tar, pax, cpio, ar, and shar
+archives.</p>
+
+<p style="margin-left:8%; margin-top: 1em">The first
+synopsis form shows a &lsquo;&lsquo;bundled&rsquo;&rsquo;
+option word. This usage is provided for compatibility with
+historical implementations. See COMPATIBILITY below for
+details.</p>
+
+<p style="margin-left:8%; margin-top: 1em">The other
+synopsis forms show the preferred usage. The first option to
+<b>tar</b> is a mode indicator from the following list:</p>
+
+<p valign="top"><b>&minus;c</b></p>
+
+<p style="margin-left:20%; margin-top: 1em">Create a new
+archive containing the specified items.</p>
+
+<p valign="top"><b>&minus;r</b></p>
+
+<p style="margin-left:20%; margin-top: 1em">Like
+<b>&minus;c</b>, but new entries are appended to the
+archive. Note that this only works on uncompressed archives
+stored in regular files. The <b>&minus;f</b> option is
+required.</p>
+
+<p valign="top"><b>&minus;t</b></p>
+
+<p style="margin-left:20%; margin-top: 1em">List archive
+contents to stdout.</p>
+
+<p valign="top"><b>&minus;u</b></p>
+
+<p style="margin-left:20%; margin-top: 1em">Like
+<b>&minus;r</b>, but new entries are added only if they have
+a modification date newer than the corresponding entry in
+the archive. Note that this only works on uncompressed
+archives stored in regular files. The <b>&minus;f</b> option
+is required.</p>
+
+<p valign="top"><b>&minus;x</b></p>
+
+<p style="margin-left:20%; margin-top: 1em">Extract to disk
+from the archive. If a file with the same name appears more
+than once in the archive, each copy will be extracted, with
+later copies overwriting (replacing) earlier copies.</p>
+
+<p style="margin-left:8%; margin-top: 1em">In
+<b>&minus;c</b>, <b>&minus;r</b>, or <b>&minus;u</b> mode,
+each specified file or directory is added to the archive in
+the order specified on the command line. By default, the
+contents of each directory are also archived.</p>
+
+<p style="margin-left:8%; margin-top: 1em">In extract or
+list mode, the entire command line is read and parsed before
+the archive is opened. The pathnames or patterns on the
+command line indicate which items in the archive should be
+processed. Patterns are shell-style globbing patterns as
+documented in tcsh(1).</p>
+
+<p style="margin-top: 1em" valign="top"><b>OPTIONS</b></p>
+
+<p style="margin-left:8%;">Unless specifically stated
+otherwise, options are applicable in all operating
+modes.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>@</b><i>archive</i></p>
+
+<p style="margin-left:20%;">(c and r mode only) The
+specified archive is opened and the entries in it will be
+appended to the current archive. As a simple example,</p>
+
+<p style="margin-left:29%;"><b>tar &minus;c &minus;f</b>
+<i>- newfile</i> <b>@</b><i>original.tar</i></p>
+
+<p style="margin-left:20%;">writes a new archive to
+standard output containing a file <i>newfile</i> and all of
+the entries from <i>original.tar</i>. In contrast,</p>
+
+<p style="margin-left:29%;"><b>tar &minus;c &minus;f</b>
+<i>- newfile original.tar</i></p>
+
+<p style="margin-left:20%;">creates a new archive with only
+two entries. Similarly,</p>
+
+<p style="margin-left:29%;"><b>tar &minus;czf</b> <i>-</i>
+<b>&minus;-format pax @</b><i>-</i></p>
+
+<p style="margin-left:20%;">reads an archive from standard
+input (whose format will be determined automatically) and
+converts it into a gzip-compressed pax-format archive on
+stdout. In this way, <b>tar</b> can be used to convert
+archives from one format to another.</p>
+
+<p style="margin-top: 1em" valign="top"><b>&minus;b</b>
+<i>blocksize</i></p>
+
+<p style="margin-left:20%;">Specify the block size, in
+512-byte records, for tape drive I/O. As a rule, this
+argument is only needed when reading from or writing to tape
+drives, and usually not even then as the default block size
+of 20 records (10240 bytes) is very common.</p>
+
+<p style="margin-top: 1em" valign="top"><b>&minus;C</b>
+<i>directory</i></p>
+
+<p style="margin-left:20%;">In c and r mode, this changes
+the directory before adding the following files. In x mode,
+change directories after opening the archive but before
+extracting entries from the archive.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>&minus;-check-links</b></p>
+
+<p style="margin-left:20%;">(c and r modes only) Issue a
+warning message unless all links to each file are
+archived.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>&minus;-chroot</b></p>
+
+<p style="margin-left:20%;">(x mode only) <b>chroot</b>()
+to the current directory after processing any
+<b>&minus;C</b> options and before extracting any files.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>&minus;-exclude</b>
+<i>pattern</i></p>
+
+<p style="margin-left:20%;">Do not process files or
+directories that match the specified pattern. Note that
+exclusions take precedence over patterns or filenames
+specified on the command line.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>&minus;-format</b>
+<i>format</i></p>
+
+<p style="margin-left:20%;">(c, r, u mode only) Use the
+specified format for the created archive. Supported formats
+include &lsquo;&lsquo;cpio&rsquo;&rsquo;,
+&lsquo;&lsquo;pax&rsquo;&rsquo;,
+&lsquo;&lsquo;shar&rsquo;&rsquo;, and
+&lsquo;&lsquo;ustar&rsquo;&rsquo;. Other formats may also be
+supported; see libarchive-formats(5) for more information
+about currently-supported formats. In r and u modes, when
+extending an existing archive, the format specified here
+must be compatible with the format of the existing archive
+on disk.</p>
+
+<p style="margin-top: 1em" valign="top"><b>&minus;f</b>
+<i>file</i></p>
+
+<p style="margin-left:20%;">Read the archive from or write
+the archive to the specified file. The filename can be
+<i>-</i> for standard input or standard output. If not
+specified, the default tape device will be used. (On
+FreeBSD, the default tape device is <i>/dev/sa0</i>.)</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>&minus;H</b></p>
+
+<p style="margin-left:20%; margin-top: 1em">(c and r mode
+only) Symbolic links named on the command line will be
+followed; the target of the link will be archived, not the
+link itself.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>&minus;h</b></p>
+
+<p style="margin-left:20%; margin-top: 1em">(c and r mode
+only) Synonym for <b>&minus;L</b>.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>&minus;I</b></p>
+
+<p style="margin-left:20%; margin-top: 1em">Synonym for
+<b>&minus;T</b>.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>&minus;-include</b>
+<i>pattern</i></p>
+
+<p style="margin-left:20%;">Process only files or
+directories that match the specified pattern. Note that
+exclusions specified with <b>&minus;-exclude</b> take
+precedence over inclusions. If no inclusions are explicitly
+specified, all entries are processed by default. The
+<b>&minus;-include</b> option is especially useful when
+filtering archives. For example, the command</p>
+
+<p style="margin-left:29%;"><b>tar &minus;c &minus;f</b>
+<i>new.tar</i> <b>&minus;-include=&rsquo;*foo*&rsquo;
+@</b><i>old.tgz</i></p>
+
+<p style="margin-left:20%;">creates a new archive
+<i>new.tar</i> containing only the entries from
+<i>old.tgz</i> containing the string &lsquo;foo&rsquo;.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>&minus;j</b></p>
+
+<p style="margin-left:20%; margin-top: 1em">(c mode only)
+Compress the resulting archive with bzip2(1). In extract or
+list modes, this option is ignored. Note that, unlike other
+<b>tar</b> implementations, this implementation recognizes
+bzip2 compression automatically when reading archives.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>&minus;k</b></p>
+
+<p style="margin-left:20%; margin-top: 1em">(x mode only)
+Do not overwrite existing files. In particular, if a file
+appears more than once in an archive, later copies will not
+overwrite earlier copies.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>&minus;-keep-newer-files</b></p>
+
+<p style="margin-left:20%;">(x mode only) Do not overwrite
+existing files that are newer than the versions appearing in
+the archive being extracted.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>&minus;L</b></p>
+
+<p style="margin-left:20%; margin-top: 1em">(c and r mode
+only) All symbolic links will be followed. Normally,
+symbolic links are archived as such. With this option, the
+target of the link will be archived instead.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>&minus;l</b></p>
+
+<p style="margin-left:20%; margin-top: 1em">This is a
+synonym for the <b>&minus;-check-links</b> option.</p>
+
+

+bundled command word. For example,</p>
+
+<p style="margin-left:17%;"><b>tar tbf 32</b>
+<i>file.tar</i></p>
+
+<p style="margin-left:8%;">specifies three flags <b>t</b>,
+<b>b</b>, and <b>f</b>. The <b>b</b> and <b>f</b> flags both
+require arguments, so there must be two additional items on
+the command line. The <i>32</i> is the argument to the
+<b>b</b> flag, and <i>file.tar</i> is the argument to the
+<b>f</b> flag.</p>
+
+<p style="margin-left:8%; margin-top: 1em">The mode options
+c, r, t, u, and x and the options b, f, l, m, o, v, and w
+comply with SUSv2.</p>
+
+<p style="margin-left:8%; margin-top: 1em">For maximum
+portability, scripts that invoke <b>tar</b> should use the
+bundled-argument format above, should limit themselves to
+the <b>c</b>, <b>t</b>, and <b>x</b> modes, and the
+<b>b</b>, <b>f</b>, <b>m</b>, <b>v</b>, and <b>w</b>
+options.</p>
+
+<p style="margin-left:8%; margin-top: 1em">Additional long

+
+
+<p style="margin-top: 1em" valign="top"><b>SECURITY</b></p>
+
+<p style="margin-left:8%;">Certain security issues are
+common to many archiving programs, including <b>tar</b>. In
+particular, carefully-crafted archives can request that
+<b>tar</b> extract files to locations outside of the target
+directory. This can potentially be used to cause unwitting
+users to overwrite files they did not intend to overwrite.
+If the archive is being extracted by the superuser, any file
+on the system can potentially be overwritten. There are
+three ways this can happen. Although <b>tar</b> has
+mechanisms to protect against each one, savvy users should
+be aware of the implications:</p>
+
+<p style="margin-top: 1em" valign="top"><b>&bull;</b></p>
+
+<p style="margin-left:20%;">Archive entries can have
+absolute pathnames. By default, <b>tar</b> removes the
+leading <i>/</i> character from filenames before restoring
+them to guard against this problem.</p>
+
+<p style="margin-top: 1em" valign="top"><b>&bull;</b></p>
+
+<p style="margin-left:20%;">Archive entries can have
+pathnames that include <i>..</i> components. By default,
+<b>tar</b> will not extract files containing <i>..</i>
+components in their pathname.</p>
+
+<p style="margin-top: 1em" valign="top"><b>&bull;</b></p>
+
+<p style="margin-left:20%;">Archive entries can exploit
+symbolic links to restore files to other directories. An
+archive can restore a symbolic link to another directory,
+then use that link to restore a file into that directory. To
+guard against this, <b>tar</b> checks each extracted path
+for symlinks. If the final path element is a symlink, it
+will be removed and replaced with the archive entry. If
+<b>&minus;U</b> is specified, any intermediate symlink will
+also be unconditionally removed. If neither <b>&minus;U</b>
+nor <b>&minus;P</b> is specified, <b>tar</b> will refuse to
+extract the entry.</p>
+
+<p style="margin-left:8%;">To protect yourself, you should
+be wary of any archives that come from untrusted sources.
+You should examine the contents of an archive with</p>
+
+<p style="margin-left:17%;"><b>tar &minus;tf</b>
+<i>filename</i></p>
+
+<p style="margin-left:8%;">before extraction. You should
+use the <b>&minus;k</b> option to ensure that <b>tar</b>
+will not overwrite any existing files or the <b>&minus;U</b>
+option to remove any pre-existing files. You should
+generally not extract archives while running with super-user
+privileges. Note that the <b>&minus;P</b> option to
+<b>tar</b> disables the security checks above and allows you
+to extract an archive while preserving any absolute
+pathnames, <i>..</i> components, or symlinks to other
+directories.</p>

+(&lsquo;&lsquo;POSIX.1&rsquo;&rsquo;). The options used by

+
+<p style="margin-left:8%;">A <b>tar</b> command appeared in
+Seventh Edition Unix, which was released in January, 1979.
+There have been numerous other implementations, many of
+which extended the file format. John Gilmore&rsquo;s
+<b>pdtar</b> public-domain implementation (circa November,
+1987) was quite influential, and formed the basis of GNU
+tar. GNU tar was included as the standard system tar in
+FreeBSD beginning with FreeBSD&nbsp;1.0.</p>
+
+<p style="margin-left:8%; margin-top: 1em">This is a

+<p style="margin-left:8%;">This program follows ISO/IEC
+9945-1:1996 (&lsquo;&lsquo;POSIX.1&rsquo;&rsquo;) for the
+definition of the <b>&minus;l</b> option. Note that GNU tar
+prior to version 1.15 treated <b>&minus;l</b> as a synonym
+for the <b>&minus;-one-file-system</b> option.</p>

+implementations.</p>
+
+<p style="margin-left:8%; margin-top: 1em">All archive
+output is written in correctly-sized blocks, even if the
+output is being compressed. Whether or not the last output
+block is padded to a full block size varies depending on the
+format and the output device. For tar and cpio formats, the
+last block of output is padded to a full block size if the
+output is being written to standard output or to a character
+or block device such as a tape drive. If the output is being
+written to a regular file, the last block will not be
+padded. Many compressors, including gzip(1) and bzip2(1),
+complain about the null padding when decompressing an
+archive created by <b>tar</b>, although they still extract
+it correctly.</p>
+
+<p style="margin-left:8%; margin-top: 1em">The compression

+
+<p style="margin-left:8%; margin-top: 1em">The <b>r</b> and
+<b>u</b> modes require that the archive be uncompressed and

+
+<p style="margin-left:8%; margin-top: 1em">To archive a

+
+<p style="margin-left:8%;">The <b>cpio</b> archive format
+collects any number of files, directories, and other file
+system objects (symbolic links, device nodes, etc.) into a
+single stream of bytes.</p>
+
+<p style="margin-left:8%; margin-top: 1em"><b>General
+Format</b> <br>
+Each file system object in a <b>cpio</b> archive comprises a
+header record with basic numeric metadata followed by the
+full pathname of the entry and the file data. The header
+record stores a series of integer values that generally
+follow the fields in <i>struct stat</i>. (See stat(2) for
+details.) The variants differ primarily in how they store
+those integers (binary, octal, or hexadecimal). The header
+is followed by the pathname of the entry (the length of the
+pathname is stored in the header) and any file data. The end
+of the archive is indicated by a special record with the
+pathname &lsquo;&lsquo;TRAILER!!!&rsquo;&rsquo;.</p>

+
+<p style="margin-top: 1em" valign="top"><b>DESCRIPTION</b></p>
+
+<p style="margin-left:8%;">The libarchive(3) library reads

+
+<p style="margin-left:8%; margin-top: 1em">The following
+provides a brief description of each format supported by
+libarchive, with some information about recognized
+extensions or limitations of the current library support.
+Note that just because a format is supported by libarchive
+does not imply that a program that uses libarchive will
+support that format. Applications that use libarchive
+specify which formats they wish to support, though many
+programs do use libarchive convenience functions to enable
+all supported formats.</p>

+<p style="margin-left:8%; margin-top: 1em"><b>Tar
+Formats</b> <br>
+The libarchive(3) library can read most tar archives.
+However, it only writes POSIX-standard
+&lsquo;&lsquo;ustar&rsquo;&rsquo; and &lsquo;&lsquo;pax
+interchange&rsquo;&rsquo; formats.</p>
+
+<p style="margin-left:8%; margin-top: 1em">All tar formats
+store each entry in one or more 512-byte records. The first
+record is used for file metadata, including filename,
+timestamp, and mode information, and the file data is stored
+in subsequent records. Later variants have extended this by
+either appropriating undefined areas of the header record,
+extending the header to multiple records, or by storing
+special entries that modify the interpretation of subsequent
+entries.</p>
+
+<p style="margin-top: 1em" valign="top"><b>gnutar</b></p>
+
+<p style="margin-left:20%; margin-top: 1em">The
+libarchive(3) library can read GNU-format tar archives. It
+currently supports the most popular GNU extensions,
+including modern long filename and linkname support, as well
+as atime and ctime data. The libarchive library does not
+support multi-volume archives, nor the old GNU long filename
+format. It can read GNU sparse file entries, including the
+new POSIX-based formats, but cannot write GNU sparse file
+entries.</p>
+
+<p style="margin-top: 1em" valign="top"><b>pax</b></p>
+
+<p style="margin-left:20%; margin-top: 1em">The
+libarchive(3) library can read and write POSIX-compliant pax
+interchange format archives. Pax interchange format archives
+are an extension of the older ustar format that adds a
+separate entry with additional attributes stored as
+key/value pairs immediately before each regular entry. The
+presence of these additional entries is the only difference
+between pax interchange format and the older ustar format.
+The extended attributes are of unlimited length and are
+stored as UTF-8 Unicode strings. Keywords defined in the
+standard are in all lowercase; vendors are allowed to define
+custom keys by preceding them with the vendor name in all
+uppercase. When writing pax archives, libarchive uses many
+of the SCHILY keys defined by Joerg Schilling&rsquo;s
+&lsquo;&lsquo;star&rsquo;&rsquo; archiver and a few
+LIBARCHIVE keys. The libarchive library can read most of the
+SCHILY keys and most of the GNU keys introduced by GNU tar.
+It silently ignores any keywords that it does not
+understand.</p>
+
+<p style="margin-top: 1em" valign="top"><b>restricted
+pax</b></p>
+
+<p style="margin-left:20%;">The libarchive library can also
+write pax archives in which it attempts to suppress the
+extended attributes entry whenever possible. The result will
+be identical to a ustar archive unless the extended
+attributes entry is required to store a long file name, long
+linkname, extended ACL, file flags, or if any of the
+standard ustar data (user name, group name, UID, GID, etc)
+cannot be fully represented in the ustar header. In all
+cases, the result can be dearchived by any program that can
+read POSIX-compliant pax interchange format archives.
+Programs that correctly read ustar format (see below) will
+also be able to read this format; any extended attributes
+will be extracted as separate files stored in
+<i>PaxHeader</i> directories.</p>
+
+<p style="margin-top: 1em" valign="top"><b>ustar</b></p>
+
+<p style="margin-left:20%; margin-top: 1em">The libarchive
+library can both read and write this format. This format has
+the following limitations:</p>
+
+<p valign="top"><b>&bull;</b></p>
+
+<p style="margin-left:26%;">Device major and minor numbers
+are limited to 21 bits. Nodes with larger numbers will not
+be added to the archive.</p>
+
+<p valign="top"><b>&bull;</b></p>
+
+<p style="margin-left:26%;">Path names in the archive are
+limited to 255 bytes. (Shorter if there is no / character in
+exactly the right place.)</p>
+
+<p valign="top"><b>&bull;</b></p>
+
+<p style="margin-left:26%;">Symbolic links and hard links
+are stored in the archive with the name of the referenced
+file. This name is limited to 100 bytes.</p>
+
+<p valign="top"><b>&bull;</b></p>
+
+<p style="margin-left:26%;">Extended attributes, file
+flags, and other extended security information cannot be
+stored.</p>
+
+<p valign="top"><b>&bull;</b></p>
+
+<p style="margin-left:26%;">Archive entries are limited to
+8 gigabytes in size.</p>
+
+<p style="margin-left:20%;">Note that the pax interchange
+format has none of these restrictions.</p>
+
+<p style="margin-left:8%; margin-top: 1em">The libarchive
+library also reads a variety of commonly-used extensions to
+the basic tar format. These extensions are recognized
+automatically whenever they appear.</p>
+
+<p style="margin-top: 1em" valign="top">Numeric
+extensions.</p>
+
+<p style="margin-left:20%;">The POSIX standards require
+fixed-length numeric fields to be written with some
+character position reserved for terminators. Libarchive
+allows these fields to be written without terminator
+characters. This extends the allowable range; in particular,
+ustar archives with this extension can support entries up to
+64 gigabytes in size. Libarchive also recognizes base-256
+values in most numeric fields. This essentially removes all
+limitations on file size, modification time, and device
+numbers.</p>
+
+<p style="margin-top: 1em" valign="top">Solaris
+extensions</p>
+
+<p style="margin-left:20%;">Libarchive recognizes ACL and
+extended attribute records written by Solaris tar.
+Currently, libarchive only has support for old-style ACLs;
+the newer NFSv4 ACLs are recognized but discarded.</p>
+
+<p style="margin-left:8%; margin-top: 1em">The first tar
+program appeared in Seventh Edition Unix in 1979. The first
+official standard for the tar file format was the
+&lsquo;&lsquo;ustar&rsquo;&rsquo; (Unix Standard Tar) format
+defined by POSIX in 1988. POSIX.1-2001 extended the ustar
+format to create the &lsquo;&lsquo;pax
+interchange&rsquo;&rsquo; format.</p>
+
+<p style="margin-left:8%; margin-top: 1em"><b>Cpio
+Formats</b> <br>
+The libarchive library can read a number of common cpio
+variants and can write &lsquo;&lsquo;odc&rsquo;&rsquo; and
+&lsquo;&lsquo;newc&rsquo;&rsquo; format archives. A cpio
+archive stores each entry as a fixed-size header followed by
+a variable-length filename and variable-length data. Unlike
+the tar format, the cpio format does only minimal padding of
+the header or file data. There are several cpio variants,
+which differ primarily in how they store the initial header:
+some store the values as octal or hexadecimal numbers in
+ASCII, others as binary values of varying byte order and
+length.</p>
+
+<p style="margin-top: 1em" valign="top"><b>binary</b></p>
+
+<p style="margin-left:20%; margin-top: 1em">The libarchive
+library transparently reads both big-endian and
+little-endian variants of the original binary cpio format.
+This format used 32-bit binary values for file size and
+mtime, and 16-bit binary values for the other fields.</p>
+
+<p style="margin-top: 1em" valign="top"><b>odc</b></p>
+
+<p style="margin-left:20%; margin-top: 1em">The libarchive
+library can both read and write this POSIX-standard format,
+which is officially known as the &lsquo;&lsquo;cpio
+interchange format&rsquo;&rsquo; or the
+&lsquo;&lsquo;octet-oriented cpio archive
+format&rsquo;&rsquo; and sometimes unofficially referred to
+as the &lsquo;&lsquo;old character format&rsquo;&rsquo;.
+This format stores the header contents as octal values in
+ASCII. It is standard, portable, and immune from byte-order
+confusion. File sizes and mtime are limited to 33 bits (8GB
+file size), other fields are limited to 18 bits.</p>
+
+<p style="margin-top: 1em" valign="top"><b>SVR4</b></p>
+
+<p style="margin-left:20%; margin-top: 1em">The libarchive
+library can read both CRC and non-CRC variants of this
+format. The SVR4 format uses eight-digit hexadecimal values
+for all header fields. This limits file size to 4GB, and
+also limits the mtime and other fields to 32 bits. The SVR4
+format can optionally include a CRC of the file contents,
+although libarchive does not currently verify this CRC.</p>
+
+<p style="margin-left:8%; margin-top: 1em">Cpio first
+appeared in PWB/UNIX 1.0, which was released within AT&amp;T
+in 1977. PWB/UNIX 1.0 formed the basis of System III Unix,
+released outside of AT&amp;T in 1981. This makes cpio older
+than tar, although cpio was not included in Version 7
+AT&amp;T Unix. As a result, the tar command became much
+better known in universities and research groups that used
+Version 7. The combination of the <b>find</b> and
+<b>cpio</b> utilities provided very precise control over
+file selection. Unfortunately, the format has many
+limitations that make it unsuitable for widespread use. Only
+the POSIX format permits files over 4GB, and its 18-bit
+limit for most other fields makes it unsuitable for modern
+systems. In addition, cpio formats only store numeric
+UID/GID values (not usernames and group names), which can
+make it very difficult to correctly transfer archives across
+systems with dissimilar user numbering.</p>
+
+<p style="margin-left:8%; margin-top: 1em"><b>Shar
+Formats</b> <br>
+A &lsquo;&lsquo;shell archive&rsquo;&rsquo; is a shell
+script that, when executed on a POSIX-compliant system, will
+recreate a collection of file system objects. The libarchive
+library can write two different kinds of shar archives:</p>
+
+<p style="margin-top: 1em" valign="top"><b>shar</b></p>
+
+<p style="margin-left:20%; margin-top: 1em">The traditional
+shar format uses a limited set of POSIX commands, including
+echo(1), mkdir(1), and sed(1). It is suitable for portably
+archiving small collections of plain text files. However, it
+is not generally well-suited for large archives (many
+implementations of sh(1) have limits on the size of a
+script) nor should it be used with non-text files.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>shardump</b></p>
+
+<p style="margin-left:20%;">This format is similar to shar
+but encodes files using uuencode(1) so that the result will
+be a plain text file regardless of the file contents. It
+also includes additional shell commands that attempt to
+reproduce as many file attributes as possible, including
+owner, mode, and flags. The additional commands used to
+restore file attributes make shardump archives less portable
+than plain shar archives.</p>
+
+<p style="margin-left:8%; margin-top: 1em"><b>ISO9660
+format</b> <br>
+Libarchive can read and extract from files containing
+ISO9660-compliant CDROM images. In many cases, this can
+remove the need to burn a physical CDROM just in order to
+read the files contained in an ISO9660 image. It also avoids
+security and complexity issues that come with virtual mounts
+and loopback devices. Libarchive supports the most common
+Rockridge extensions and has partial support for Joliet
+extensions. If both extensions are present, the Joliet
+extensions will be used and the Rockridge extensions will be
+ignored. In particular, this can create problems with
+hardlinks and symlinks, which are supported by Rockridge but
+not by Joliet.</p>
+
+<p style="margin-left:8%; margin-top: 1em"><b>Zip
+format</b> <br>
+Libarchive can read and write zip format archives that have
+uncompressed entries and entries compressed with the
+&lsquo;&lsquo;deflate&rsquo;&rsquo; algorithm. Older zip
+compression algorithms are not supported. It can extract jar
+archives, archives that use Zip64 extensions and many
+self-extracting zip archives. Libarchive reads Zip archives
+as they are being streamed, which allows it to read archives
+of arbitrary size. It currently does not use the central
+directory; this limits libarchive&rsquo;s ability to support
+some self-extracting archives and ones that have been
+modified in certain ways.</p>
+
+<p style="margin-left:8%; margin-top: 1em"><b>Archive
+(library) file format</b> <br>
+The Unix archive format (commonly created by the ar(1)
+archiver) is a general-purpose format which is used almost
+exclusively for object files to be read by the link editor
+ld(1). The ar format has never been standardised. There are
+two common variants: the GNU format derived from SVR4, and
+the BSD format, which first appeared in 4.4BSD. The two
+differ primarily in their handling of filenames longer than
+15 characters: the GNU/SVR4 variant writes a filename table
+at the beginning of the archive; the BSD format stores each
+long filename in an extension area adjacent to the entry.
+Libarchive can read both extensions, including archives that
+may include both types of long filenames. Programs using
+libarchive can write GNU/SVR4 format if they provide a
+filename table to be written into the archive before any of
+the entries. Any entries whose names are not in the filename
+table will be written using BSD-style long filenames. This
+can cause problems for programs such as GNU ld that do not
+support the BSD-style long filenames.</p>
+
+<p style="margin-left:8%; margin-top: 1em"><b>mtree</b>
+<br>
+Libarchive can read and write files in mtree(5) format. This
+format is not a true archive format, but rather a textual
+description of a file hierarchy in which each line specifies
+the name of a file and provides specific metadata about that
+file. Libarchive can read all of the keywords supported by
+both the NetBSD and FreeBSD versions of mtree(1), although
+many of the keywords cannot currently be stored in an
+archive_entry object. When writing, libarchive supports use
+of the archive_write_set_options(3) interface to specify
+which keywords should be included in the output. If
+libarchive was compiled with access to suitable
+cryptographic libraries (such as the OpenSSL libraries), it
+can compute hash entries such as <b>sha512</b> or <b>md5</b>
+from file data being written to the mtree writer.</p>
+
+<p style="margin-left:8%; margin-top: 1em">When reading an
+mtree file, libarchive will locate the corresponding files
+on disk using the <b>contents</b> keyword if present or the
+regular filename. If it can locate and open the file on
+disk, it will use that to fill in any metadata that is
+missing from the mtree file and will read the file contents
+and return those to the program using libarchive. If it
+cannot locate and open the file on disk, libarchive will
+return an error for any attempt to read the entry body.</p>

+<p style="margin-top: 1em" valign="top"><b>OVERVIEW</b></p>
+
+<p style="margin-left:8%;">The <b>libarchive</b> library
+provides a flexible interface for reading and writing
+streaming archive files such as tar and cpio. The library is
+inherently stream-oriented; readers serially iterate through
+the archive, writers serially add things to the archive. In
+particular, note that there is no built-in support for
+random access nor for in-place modification.</p>
+
+<p style="margin-left:8%; margin-top: 1em">When reading an
+archive, the library automatically detects the format and

+extension of the tar archive format that eliminates
+essentially all of the limitations of historic tar formats
+in a standard fashion that is supported by POSIX-compliant
+pax(1) implementations on many systems as well as several
+newer implementations of tar(1). Note that the default write
+format will suppress the pax extended attributes for most
+entries; explicitly requesting pax format will enable those
+attributes for all entries.</p>
+
+<p style="margin-left:8%; margin-top: 1em">The read and
+write APIs are accessed through the
+<b>archive_read_XXX</b>() functions and the
+<b>archive_write_XXX</b>() functions, respectively, and
+either can be used independently of the other.</p>
+
+<p style="margin-left:8%; margin-top: 1em">The rest of this
+manual page provides an overview of the library operation.
+More detailed information can be found in the individual
+manual pages for each API or utility function.</p>
+
+<p style="margin-top: 1em" valign="top"><b>READING AN
+ARCHIVE</b></p>
+
+<p style="margin-left:8%;">To read an archive, you must
+first obtain an initialized struct archive object from
+<b>archive_read_new</b>(). You can then modify this object
+for the desired operations with the various
+<b>archive_read_set_XXX</b>() and
+<b>archive_read_support_XXX</b>() functions. In particular,
+you will need to invoke appropriate
+<b>archive_read_support_XXX</b>() functions to enable the
+corresponding compression and format support. Note that
+these latter functions perform two distinct operations: they
+cause the corresponding support code to be linked into your
+program, and they enable the corresponding auto-detect code.
+Unless you have specific constraints, you will generally
+want to invoke <b>archive_read_support_compression_all</b>()
+and <b>archive_read_support_format_all</b>() to enable
+auto-detect for all formats and compression types currently
+supported by the library.</p>
+
+<p style="margin-left:8%; margin-top: 1em">Once you have
+prepared the struct archive object, you call
+<b>archive_read_open</b>() to actually open the archive and
+prepare it for reading. There are several variants of this
+function; the most basic expects you to provide pointers to
+several functions that can provide blocks of bytes from the
+archive. There are convenience forms that allow you to
+specify a filename, file descriptor, <i>FILE *</i> object,
+or a block of memory from which to read the archive data.
+Note that the core library makes no assumptions about the
+size of the blocks read; callback functions are free to read
+whatever block size is most appropriate for the medium.</p>
+
+<p style="margin-left:8%; margin-top: 1em">Each archive
+entry consists of a header followed by a certain amount of
+data. You can obtain the next header with
+<b>archive_read_next_header</b>(), which returns a pointer
+to an struct archive_entry structure with information about
+the current archive element. If the entry is a regular file,
+then the header will be followed by the file data. You can
+use <b>archive_read_data</b>() (which works much like the
+read(2) system call) to read this data from the archive. You
+may prefer to use the higher-level
+<b>archive_read_data_skip</b>(), which reads and discards
+the data for this entry,
+<b>archive_read_data_to_buffer</b>(), which reads the data
+into an in-memory buffer,
+<b>archive_read_data_to_file</b>(), which copies the data to
+the provided file descriptor, or
+<b>archive_read_extract</b>(), which recreates the specified
+entry on disk and copies data from the archive. In
+particular, note that <b>archive_read_extract</b>() uses the
+struct archive_entry structure that you provide it, which
+may differ from the entry just read from the archive. In
+particular, many applications will want to override the
+pathname, file permissions, or ownership.</p>
+
+<p style="margin-left:8%; margin-top: 1em">Once you have
+finished reading data from the archive, you should call
+<b>archive_read_close</b>() to close the archive, then call
+<b>archive_read_finish</b>() to release all resources,
+including all memory allocated by the library.</p>
+
+<p style="margin-left:8%; margin-top: 1em">The
+archive_read(3) manual page provides more detailed calling
+information for this API.</p>
+
+<p style="margin-top: 1em" valign="top"><b>WRITING AN
+ARCHIVE</b></p>
+
+<p style="margin-left:8%;">You use a similar process to
+write an archive. The <b>archive_write_new</b>() function
+creates an archive object useful for writing, the various
+<b>archive_write_set_XXX</b>() functions are used to set
+parameters for writing the archive, and
+<b>archive_write_open</b>() completes the setup and opens
+the archive for writing.</p>
+
+<p style="margin-left:8%; margin-top: 1em">Individual
+archive entries are written in a three-step process: You
+first initialize a struct archive_entry structure with
+information about the new entry. At a minimum, you should
+set the pathname of the entry and provide a <i>struct
+stat</i> with a valid <i>st_mode</i> field, which specifies
+the type of object and <i>st_size</i> field, which specifies
+the size of the data portion of the object. The
+<b>archive_write_header</b>() function actually writes the
+header data to the archive. You can then use
+<b>archive_write_data</b>() to write the actual data.</p>
+
+<p style="margin-left:8%; margin-top: 1em">After all
+entries have been written, use the
+<b>archive_write_finish</b>() function to release all
+resources.</p>
+
+<p style="margin-left:8%; margin-top: 1em">The
+archive_write(3) manual page provides more detailed calling
+information for this API.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>DESCRIPTION</b></p>
+
+<p style="margin-left:8%;">Detailed descriptions of each
+function are provided by the corresponding manual pages.</p>
+
+<p style="margin-left:8%; margin-top: 1em">All of the
+functions utilize an opaque struct archive datatype that
+provides access to the archive contents.</p>
+
+<p style="margin-left:8%; margin-top: 1em">The struct
+archive_entry structure contains a complete description of a
+single archive entry. It uses an opaque interface that is
+fully documented in archive_entry(3).</p>
+
+<p style="margin-left:8%; margin-top: 1em">Users familiar
+with historic formats should be aware that the newer
+variants have eliminated most restrictions on the length of
+textual fields. Clients should not assume that filenames,
+link names, user names, or group names are limited in
+length. In particular, pax interchange format can easily
+accommodate pathnames in arbitrary character sets that
+exceed <i>PATH_MAX</i>.</p>
+
+<p style="margin-top: 1em" valign="top"><b>RETURN
+VALUES</b></p>
+
+<p style="margin-left:8%;">Most functions return zero on
+success, non-zero on error. The return value indicates the
+general severity of the error, ranging from
+<b>ARCHIVE_WARN</b>, which indicates a minor problem that
+should probably be reported to the user, to
+<b>ARCHIVE_FATAL</b>, which indicates a serious problem that
+will prevent any further operations on this archive. On
+error, the <b>archive_errno</b>() function can be used to
+retrieve a numeric error code (see errno(2)). The
+<b>archive_error_string</b>() returns a textual error
+message suitable for display.</p>

+Manual LIBARCHIVE(3)</p>
+
+<p style="margin-top: 1em" valign="top"><b>NAME</b></p>
+
+<p style="margin-left:8%;"><b>libarchive_internals</b>
+&mdash; description of libarchive internal interfaces</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>OVERVIEW</b></p>
+
+<p style="margin-left:8%;">The <b>libarchive</b> library
+provides a flexible interface for reading and writing
+streaming archive files such as tar and cpio. Internally, it
+follows a modular layered design that should make it easy to
+add new archive and compression formats.</p>
+
+<p style="margin-top: 1em" valign="top"><b>GENERAL
+ARCHITECTURE</b></p>
+
+<p style="margin-left:8%;">Externally, libarchive exposes
+most operations through an opaque, object-style interface.
+The archive_entry(1) objects store information about a
+single filesystem object. The rest of the library provides
+facilities to write archive_entry(1) objects to archive
+files, read them from archive files, and write them to disk.
+(There are plans to add a facility to read archive_entry(1)
+objects from disk as well.)</p>
+
+<p style="margin-left:8%; margin-top: 1em">The read and
+write APIs each have four layers: a public API layer, a
+format layer that understands the archive file format, a
+compression layer, and an I/O layer. The I/O layer is
+completely exposed to clients who can replace it entirely
+with their own functions.</p>
+
+<p style="margin-left:8%; margin-top: 1em">In order to
+provide as much consistency as possible for clients, some
+public functions are virtualized. Eventually, it should be
+possible for clients to open an archive or disk writer, and
+then use a single set of code to select and write entries,
+regardless of the target.</p>
+
+<p style="margin-top: 1em" valign="top"><b>READ
+ARCHITECTURE</b></p>
+
+<p style="margin-left:8%;">From the outside, clients use
+the archive_read(3) API to manipulate an <b>archive</b>
+object to read entries and bodies from an archive stream.
+Internally, the <b>archive</b> object is cast to an
+<b>archive_read</b> object, which holds all read-specific
+data. The API has four layers: The lowest layer is the I/O
+layer. This layer can be overridden by clients, but most
+clients use the packaged I/O callbacks provided, for
+example, by archive_read_open_memory(3), and
+archive_read_open_fd(3). The compression layer calls the I/O
+layer to read bytes and decompresses them for the format
+layer. The format layer unpacks a stream of uncompressed
+bytes and creates <b>archive_entry</b> objects from the
+incoming data. The API layer tracks overall state (for
+example, it prevents clients from reading data before
+reading a header) and invokes the format and compression
+layer operations through registered function pointers. In
+particular, the API layer drives the format-detection
+process: When opening the archive, it reads an initial block
+of data and offers it to each registered compression
+handler. The one with the highest bid is initialized with
+the first block. Similarly, the format handlers are polled
+to see which handler is the best for each archive. (Prior to
+2.4.0, the format bidders were invoked for each entry, but
+this design hindered error recovery.)</p>
+
+<p style="margin-left:8%; margin-top: 1em"><b>I/O Layer and
+Client Callbacks</b> <br>
+The read API goes to some lengths to be nice to clients. As
+a result, there are few restrictions on the behavior of the
+client callbacks.</p>
+
+<p style="margin-left:8%; margin-top: 1em">The client read
+callback is expected to provide a block of data on each
+call. A zero-length return does indicate end of file, but
+otherwise blocks may be as small as one byte or as large as
+the entire file. In particular, blocks may be of different
+sizes.</p>
+
+<p style="margin-left:8%; margin-top: 1em">The client skip
+callback returns the number of bytes actually skipped, which
+may be much smaller than the skip requested. The only
+requirement is that the skip not be larger. In particular,
+clients are allowed to return zero for any skip that they
+don&rsquo;t want to handle. The skip callback must never be
+invoked with a negative value.</p>
+
+<p style="margin-left:8%; margin-top: 1em">Keep in mind
+that not all clients are reading from disk: clients reading
+from networks may provide different-sized blocks on every
+request and cannot skip at all; advanced clients may use
+mmap(2) to read the entire file into memory at once and
+return the entire file to libarchive as a single block;
+other clients may begin asynchronous I/O operations for the
+next block on each request.</p>
+
+
+<p style="margin-left:8%; margin-top: 1em"><b>Decompresssion
+Layer</b> <br>
+The decompression layer not only handles decompression, it
+also buffers data so that the format handlers see a much
+nicer I/O model. The decompression API is a two stage
+peek/consume model. A read_ahead request specifies a minimum
+read amount; the decompression layer must provide a pointer
+to at least that much data. If more data is immediately
+available, it should return more: the format layer handles
+bulk data reads by asking for a minimum of one byte and then
+copying as much data as is available.</p>
+
+<p style="margin-left:8%; margin-top: 1em">A subsequent
+call to the <b>consume</b>() function advances the read
+pointer. Note that data returned from a <b>read_ahead</b>()
+call is guaranteed to remain in place until the next call to
+<b>read_ahead</b>(). Intervening calls to <b>consume</b>()
+should not cause the data to move.</p>
+
+<p style="margin-left:8%; margin-top: 1em">Skip requests
+must always be handled exactly. Decompression handlers that
+cannot seek forward should not register a skip handler; the
+API layer fills in a generic skip handler that reads and
+discards data.</p>
+
+<p style="margin-left:8%; margin-top: 1em">A decompression
+handler has a specific lifecycle:</p>
+
+<p valign="top">Registration/Configuration</p>
+
+<p style="margin-left:20%;">When the client invokes the
+public support function, the decompression handler invokes
+the internal <b>__archive_read_register_compression</b>()
+function to provide bid and initialization functions. This
+function returns <b>NULL</b> on error or else a pointer to a
+<b>struct decompressor_t</b>. This structure contains a
+<i>void * config</i> slot that can be used for storing any
+customization information.</p>
+
+<p valign="top">Bid</p>
+
+<p style="margin-left:20%; margin-top: 1em">The bid
+function is invoked with a pointer and size of a block of
+data. The decompressor can access its config data through
+the <i>decompressor</i> element of the <b>archive_read</b>
+object. The bid function is otherwise stateless. In
+particular, it must not perform any I/O operations.</p>
+
+<p style="margin-left:20%; margin-top: 1em">The value
+returned by the bid function indicates its suitability for
+handling this data stream. A bid of zero will ensure that
+this decompressor is never invoked. Return zero if magic
+number checks fail. Otherwise, your initial implementation
+should return the number of bits actually checked. For
+example, if you verify two full bytes and three bits of
+another byte, bid 19. Note that the initial block may be
+very short; be careful to only inspect the data you are
+given. (The current decompressors require two bytes for
+correct bidding.)</p>
+
+<p valign="top">Initialize</p>
+
+<p style="margin-left:20%;">The winning bidder will have
+its init function called. This function should initialize
+the remaining slots of the <i>struct decompressor_t</i>
+object pointed to by the <i>decompressor</i> element of the
+<i>archive_read</i> object. In particular, it should
+allocate any working data it needs in the <i>data</i> slot
+of that structure. The init function is called with the
+block of data that was used for tasting. At this point, the
+decompressor is responsible for all I/O requests to the
+client callbacks. The decompressor is free to read more data
+as and when necessary.</p>
+
+<p valign="top">Satisfy I/O requests</p>
+
+<p style="margin-left:20%;">The format handler will invoke
+the <i>read_ahead</i>, <i>consume</i>, and <i>skip</i>
+functions as needed.</p>
+
+<p valign="top">Finish</p>
+
+<p style="margin-left:20%; margin-top: 1em">The finish
+method is called only once when the archive is closed. It
+should release anything stored in the <i>data</i> and
+<i>config</i> slots of the <i>decompressor</i> object. It
+should not invoke the client close callback.</p>
+
+<p style="margin-left:8%; margin-top: 1em"><b>Format
+Layer</b> <br>
+The read formats have a similar lifecycle to the
+decompression handlers:</p>
+
+<p valign="top">Registration</p>
+
+<p style="margin-left:20%;">Allocate your private data and
+initialize your pointers.</p>
+
+<p valign="top">Bid</p>
+
+<p style="margin-left:20%; margin-top: 1em">Formats bid by
+invoking the <b>read_ahead</b>() decompression method but
+not calling the <b>consume</b>() method. This allows each
+bidder to look ahead in the input stream. Bidders should not
+look further ahead than necessary, as long look aheads put
+pressure on the decompression layer to buffer lots of data.
+Most formats only require a few hundred bytes of look ahead;
+look aheads of a few kilobytes are reasonable. (The ISO9660
+reader sometimes looks ahead by 48k, which should be
+considered an upper limit.)</p>
+
+<p valign="top">Read header</p>
+
+<p style="margin-left:20%;">The header read is usually the
+most complex part of any format. There are a few strategies
+worth mentioning: For formats such as tar or cpio, reading
+and parsing the header is straightforward since headers
+alternate with data. For formats that store all header data
+at the beginning of the file, the first header read request
+may have to read all headers into memory and store that
+data, sorted by the location of the file data. Subsequent
+header read requests will skip forward to the beginning of
+the file data and return the corresponding header.</p>
+
+<p valign="top">Read Data</p>
+
+<p style="margin-left:20%;">The read data interface
+supports sparse files; this requires that each call return a
+block of data specifying the file offset and size. This may
+require you to carefully track the location so that you can
+return accurate file offsets for each read. Remember that
+the decompressor will return as much data as it has.
+Generally, you will want to request one byte, examine the
+return value to see how much data is available, and possibly
+trim that to the amount you can use. You should invoke
+consume for each block just before you return it.</p>
+
+<p valign="top">Skip All Data</p>
+
+<p style="margin-left:20%;">The skip data call should skip
+over all file data and trailing padding. This is called
+automatically by the API layer just before each header read.
+It is also called in response to the client calling the
+public <b>data_skip</b>() function.</p>
+
+<p valign="top">Cleanup</p>
+
+<p style="margin-left:20%;">On cleanup, the format should
+release all of its allocated memory.</p>
+
+<p style="margin-left:8%; margin-top: 1em"><b>API Layer</b>
+<br>
+XXX to do XXX</p>
+
+<p style="margin-top: 1em" valign="top"><b>WRITE
+ARCHITECTURE</b></p>
+
+<p style="margin-left:8%;">The write API has a similar set
+of four layers: an API layer, a format layer, a compression
+layer, and an I/O layer. The registration here is much
+simpler because only one format and one compression can be
+registered at a time.</p>
+
+<p style="margin-left:8%; margin-top: 1em"><b>I/O Layer and
+Client Callbacks</b> <br>
+XXX To be written XXX</p>
+
+<p style="margin-left:8%; margin-top: 1em"><b>Compression
+Layer</b> <br>
+XXX To be written XXX</p>
+
+<p style="margin-left:8%; margin-top: 1em"><b>Format
+Layer</b> <br>
+XXX To be written XXX</p>
+
+<p style="margin-left:8%; margin-top: 1em"><b>API Layer</b>
+<br>
+XXX To be written XXX</p>
+
+<p style="margin-top: 1em" valign="top"><b>WRITE_DISK
+ARCHITECTURE</b></p>
+
+<p style="margin-left:8%;">The write_disk API is intended
+to look just like the write API to clients. Since it does
+not handle multiple formats or compression, it is not
+layered internally.</p>
+
+<p style="margin-top: 1em" valign="top"><b>GENERAL
+SERVICES</b></p>
+
+<p style="margin-left:8%;">The <b>archive_read</b>,
+<b>archive_write</b>, and <b>archive_write_disk</b> objects
+all contain an initial <b>archive</b> object which provides
+common support for a set of standard services. (Recall that
+ANSI/ISO C90 guarantees that you can cast freely between a
+pointer to a structure and a pointer to the first element of
+that structure.) The <b>archive</b> object has a magic value
+that indicates which API this object is associated with,
+slots for storing error information, and function pointers
+for virtualized API functions.</p>
+
+<p style="margin-top: 1em" valign="top"><b>MISCELLANEOUS
+NOTES</b></p>
+
+<p style="margin-left:8%;">Connecting existing archiving
+libraries into libarchive is generally quite difficult. In
+particular, many existing libraries strongly assume that you
+are reading from a file; they seek forwards and backwards as
+necessary to locate various pieces of information. In
+contrast, libarchive never seeks backwards in its input,
+which sometimes requires very different approaches.</p>
+
+<p style="margin-left:8%; margin-top: 1em">For example,
+libarchive&rsquo;s ISO9660 support operates very differently
+from most ISO9660 readers. The libarchive support utilizes a
+work-queue design that keeps a list of known entries sorted
+by their location in the input. Whenever libarchive&rsquo;s
+ISO9660 implementation is asked for the next header, checks
+this list to find the next item on the disk. Directories are
+parsed when they are encountered and new items are added to
+the list. This design relies heavily on the ISO9660 image
+being optimized so that directories always occur earlier on
+the disk than the files they describe.</p>
+
+<p style="margin-left:8%; margin-top: 1em">Depending on the
+specific format, such approaches may not be possible. The
+ZIP format specification, for example, allows archivers to
+store key information only at the end of the file. In
+theory, it is possible to create ZIP archives that cannot be
+read without seeking. Fortunately, such archives are very
+rare, and libarchive can read most ZIP archives, though it
+cannot always extract as much information as a dedicated ZIP
+program.</p>

+<p style="margin-left:8%;"><b>mtree</b> &mdash; format of
+mtree dir hierarchy files</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>DESCRIPTION</b></p>
+
+<p style="margin-left:8%;">The <b>mtree</b> format is a
+textual format that describes a collection of filesystem
+objects. Such files are typically used to create or verify
+directory hierarchies.</p>
+
+<p style="margin-left:8%; margin-top: 1em"><b>General
+Format</b> <br>
+An <b>mtree</b> file consists of a series of lines, each
+providing information about a single filesystem object.
+Leading whitespace is always ignored.</p>
+
+<p style="margin-left:8%; margin-top: 1em">When encoding
+file or pathnames, any backslash character or character
+outside of the 95 printable ASCII characters must be encoded
+as a a backslash followed by three octal digits. When
+reading mtree files, any appearance of a backslash followed
+by three octal digits should be converted into the
+corresponding character.</p>
+
+<p style="margin-left:8%; margin-top: 1em">Each line is
+interpreted independently as one of the following types:</p>
+
+<p style="margin-top: 1em" valign="top">Signature</p>
+
+<p style="margin-left:26%; margin-top: 1em">The first line
+of any mtree file must begin with
+&lsquo;&lsquo;#mtree&rsquo;&rsquo;. If a file contains any
+full path entries, the first line should begin with
+&lsquo;&lsquo;#mtree v2.0&rsquo;&rsquo;, otherwise, the
+first line should begin with &lsquo;&lsquo;#mtree
+v1.0&rsquo;&rsquo;.</p>
+
+<p style="margin-top: 1em" valign="top">Blank</p>
+
+<p style="margin-left:26%; margin-top: 1em">Blank lines are
+ignored.</p>
+
+<p style="margin-top: 1em" valign="top">Comment</p>
+
+<p style="margin-left:26%; margin-top: 1em">Lines beginning
+with <b>#</b> are ignored.</p>
+
+<p style="margin-top: 1em" valign="top">Special</p>
+
+<p style="margin-left:26%; margin-top: 1em">Lines beginning
+with <b>/</b> are special commands that influence the
+interpretation of later lines.</p>
+
+<p style="margin-top: 1em" valign="top">Relative</p>
+
+<p style="margin-left:26%; margin-top: 1em">If the first
+whitespace-delimited word has no <b>/</b> characters, it is
+the name of a file in the current directory. Any relative
+entry that describes a directory changes the current
+directory.</p>
+
+<p style="margin-top: 1em" valign="top">dot-dot</p>
+
+<p style="margin-left:26%; margin-top: 1em">As a special
+case, a relative entry with the filename <i>..</i> changes
+the current directory to the parent directory. Options on
+dot-dot entries are always ignored.</p>
+
+<p style="margin-top: 1em" valign="top">Full</p>
+
+<p style="margin-left:26%; margin-top: 1em">If the first
+whitespace-delimited word has a <b>/</b> character after the
+first character, it is the pathname of a file relative to
+the starting directory. There can be multiple full entries
+describing the same file.</p>
+
+<p style="margin-left:8%; margin-top: 1em">Some tools that
+process <b>mtree</b> files may require that multiple lines
+describing the same file occur consecutively. It is not
+permitted for the same file to be mentioned using both a
+relative and a full file specification.</p>
+
+<p style="margin-left:8%; margin-top: 1em"><b>Special
+commands</b> <br>
+Two special commands are currently defined:</p>
+
+<p style="margin-top: 1em" valign="top"><b>/set</b></p>
+
+<p style="margin-left:26%; margin-top: 1em">This command
+defines default values for one or more keywords. It is
+followed on the same line by one or more
+whitespace-separated keyword definitions. These definitions
+apply to all following files that do not specify a value for
+that keyword.</p>
+
+<p style="margin-top: 1em" valign="top"><b>/unset</b></p>
+
+<p style="margin-left:26%; margin-top: 1em">This command
+removes any default value set by a previous <b>/set</b>
+command. It is followed on the same line by one or more
+keywords separated by whitespace.</p>
+
+<p style="margin-left:8%; margin-top: 1em"><b>Keywords</b>
+<br>
+After the filename, a full or relative entry consists of
+zero or more whitespace-separated keyword definitions. Each
+such definition consists of a key from the following list
+immediately followed by an &rsquo;=&rsquo; sign and a value.
+Software programs reading mtree files should warn about
+unrecognized keywords.</p>
+
+<p style="margin-left:8%; margin-top: 1em">Currently
+supported keywords are as follows:</p>
+
+<p style="margin-top: 1em" valign="top"><b>cksum</b></p>
+
+<p style="margin-left:26%; margin-top: 1em">The checksum of
+the file using the default algorithm specified by the
+cksum(1) utility.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>contents</b></p>
+
+<p style="margin-left:26%; margin-top: 1em">The full
+pathname of a file that holds the contents of this file.</p>
+
+<p style="margin-top: 1em" valign="top"><b>flags</b></p>
+
+<p style="margin-left:26%; margin-top: 1em">The file flags
+as a symbolic name. See chflags(1) for information on these
+names. If no flags are to be set the string
+&lsquo;&lsquo;none&rsquo;&rsquo; may be used to override the

+attacks have demonstrated weaknesses in MD5. The SHA-256

+<p style="margin-top: 1em" valign="top"><b>NAME</b></p>
+
+<p style="margin-left:8%;"><b>tar</b> &mdash; format of
+tape archive files</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>DESCRIPTION</b></p>
+
+<p style="margin-left:8%;">The <b>tar</b> archive format
+collects any number of files, directories, and other file
+system objects (symbolic links, device nodes, etc.) into a
+single stream of bytes. The format was originally designed
+to be used with tape drives that operate with fixed-size
+blocks, but is widely used as a general packaging
+mechanism.</p>
+
+<p style="margin-left:8%; margin-top: 1em"><b>General
+Format</b> <br>
+A <b>tar</b> archive consists of a series of 512-byte
+records. Each file system object requires a header record
+which stores basic metadata (pathname, owner, permissions,
+etc.) and zero or more records containing any file data. The
+end of the archive is indicated by two records consisting
+entirely of zero bytes.</p>
+
+<p style="margin-left:8%; margin-top: 1em">For
+compatibility with tape drives that use fixed block sizes,
+programs that read or write tar files always read or write a
+fixed number of records with each I/O operation. These
+&lsquo;&lsquo;blocks&rsquo;&rsquo; are always a multiple of
+the record size. The maximum block size supported by early
+implementations was 10240 bytes or 20 records. This is still
+the default for most implementations although block sizes of
+1MiB (2048 records) or larger are commonly used with modern
+high-speed tape drives. (Note: the terms
+&lsquo;&lsquo;block&rsquo;&rsquo; and
+&lsquo;&lsquo;record&rsquo;&rsquo; here are not entirely
+standard; this document follows the convention established
+by John Gilmore in documenting <b>pdtar</b>.)</p>
+
+<p style="margin-left:8%; margin-top: 1em"><b>Old-Style
+Archive Format</b> <br>
+The original tar archive format has been extended many times
+to include additional information that various implementors
+found necessary. This section describes the variant
+implemented by the tar command included in Version&nbsp;7
+AT&amp;T UNIX, which seems to be the earliest widely-used
+version of the tar program.</p>
+
+<p style="margin-left:8%; margin-top: 1em">The header
+record for an old-style <b>tar</b> archive consists of the
+following:</p>
+
+<p style="margin-left:17%; margin-top: 1em">struct
+header_old_tar {</p>

+
+<p style="margin-left:17%;">};</p>
+
+<p style="margin-left:8%;">All unused bytes in the header
+record are filled with nulls.</p>
+
+<p style="margin-top: 1em" valign="top"><i>name</i></p>
+
+<p style="margin-left:20%; margin-top: 1em">Pathname,
+stored as a null-terminated string. Early tar
+implementations only stored regular files (including
+hardlinks to those files). One common early convention used
+a trailing &quot;/&quot; character to indicate a directory
+name, allowing directory permissions and owner information
+to be archived and restored.</p>

+
+<p style="margin-left:20%; margin-top: 1em">Size of file,
+as octal number in ASCII. For regular files only, this
+indicates the amount of data that follows the header. In
+particular, this field was ignored by early tar
+implementations when extracting hardlinks. Modern writers
+should always store a zero length for hardlink entries.</p>
+
+<p style="margin-top: 1em" valign="top"><i>mtime</i></p>
+
+<p style="margin-left:20%; margin-top: 1em">Modification
+time of file, as an octal number in ASCII. This indicates
+the number of seconds since the start of the epoch, 00:00:00
+UTC January 1, 1970. Note that negative values should be
+avoided here, as they are handled inconsistently.</p>
+
+
+<p style="margin-top: 1em" valign="top"><i>checksum</i></p>
+
+<p style="margin-left:20%;">Header checksum, stored as an
+octal number in ASCII. To compute the checksum, set the
+checksum field to all spaces, then sum all bytes in the
+header using unsigned arithmetic. This field should be
+stored as six octal digits followed by a null and a space
+character. Note that many early implementations of tar used
+signed arithmetic for the checksum field, which can cause
+interoperability problems when transferring archives between
+systems. Modern robust readers compute the checksum both
+ways and accept the header if either computation
+matches.</p>
+
+<p style="margin-top: 1em" valign="top"><i>linkflag</i>,
+<i>linkname</i></p>
+
+<p style="margin-left:20%;">In order to preserve hardlinks
+and conserve tape, a file with multiple links is only
+written to the archive the first time it is encountered. The
+next time it is encountered, the <i>linkflag</i> is set to
+an ASCII &lsquo;1&rsquo; and the <i>linkname</i> field holds
+the first name under which this file appears. (Note that
+regular files have a null value in the <i>linkflag</i>
+field.)</p>
+
+<p style="margin-left:8%; margin-top: 1em">Early tar
+implementations varied in how they terminated these fields.
+The tar command in Version&nbsp;7 AT&amp;T UNIX used the
+following conventions (this is also documented in early BSD
+manpages): the pathname must be null-terminated; the mode,
+uid, and gid fields must end in a space and a null byte; the
+size and mtime fields must end in a space; the checksum is
+terminated by a null and a space. Early implementations
+filled the numeric fields with leading spaces. This seems to
+have been common practice until the IEEE Std 1003.1-1988
+(&lsquo;&lsquo;POSIX.1&rsquo;&rsquo;) standard was released.
+For best portability, modern implementations should fill the
+numeric fields with leading zeros.</p>
+
+<p style="margin-left:8%; margin-top: 1em"><b>Pre-POSIX
+Archives</b> <br>
+An early draft of IEEE Std 1003.1-1988
+(&lsquo;&lsquo;POSIX.1&rsquo;&rsquo;) served as the basis
+for John Gilmore&rsquo;s <b>pdtar</b> program and many
+system implementations from the late 1980s and early 1990s.
+These archives generally follow the POSIX ustar format
+described below with the following variations:</p>
+
+<p valign="top"><b>&bull;</b></p>
+
+<p style="margin-left:20%;">The magic value is
+&lsquo;&lsquo;ustar&nbsp;&rsquo;&rsquo; (note the following
+space). The version field contains a space character
+followed by a null.</p>
+
+<p valign="top"><b>&bull;</b></p>
+
+<p style="margin-left:20%;">The numeric fields are
+generally filled with leading spaces (not leading zeros as
+recommended in the final standard).</p>
+
+<p valign="top"><b>&bull;</b></p>
+
+<p style="margin-left:20%;">The prefix field is often not
+used, limiting pathnames to the 100 characters of old-style
+archives.</p>
+
+<p style="margin-left:8%; margin-top: 1em"><b>POSIX ustar
+Archives</b> <br>
+IEEE Std 1003.1-1988 (&lsquo;&lsquo;POSIX.1&rsquo;&rsquo;)
+defined a standard tar file format to be read and written by
+compliant implementations of tar(1). This format is often
+called the &lsquo;&lsquo;ustar&rsquo;&rsquo; format, after
+the magic value used in the header. (The name is an acronym
+for &lsquo;&lsquo;Unix Standard TAR&rsquo;&rsquo;.) It
+extends the historic format with new fields:</p>

+<p style="margin-left:20%;">It is worth noting that the

+going into the prefix field. If the prefix field is not
+empty, the reader will prepend the prefix value and a
+<i>/</i> character to the regular name field to obtain the

+reasons.</p>

+
+<p style="margin-left:8%; margin-top: 1em">Field

+and <i>gname</i> fields must have a trailing NUL. The
+<i>pathname</i>, <i>linkname</i>, and <i>prefix</i> fields
+must have a trailing NUL unless they fill the entire field.
+(In particular, it is possible to store a 256-character
+pathname if it happens to have a <i>/</i> as the 156th
+character.) POSIX requires numeric fields to be zero-padded
+in the front, and requires them to be terminated with either
+space or NUL characters.</p>
+
+<p style="margin-left:8%; margin-top: 1em">Currently, most
+tar implementations comply with the ustar format,
+occasionally extending it by adding new fields to the blank
+area at the end of the header record.</p>
+
+<p style="margin-left:8%; margin-top: 1em"><b>Pax
+Interchange Format</b> <br>
+There are many attributes that cannot be portably stored in
+a POSIX ustar archive. IEEE Std 1003.1-2001
+(&lsquo;&lsquo;POSIX.1&rsquo;&rsquo;) defined a
+&lsquo;&lsquo;pax interchange format&rsquo;&rsquo; that uses
+two new types of entries to hold text-formatted metadata
+that applies to following entries. Note that a pax
+interchange format archive is a ustar archive in every
+respect. The new data is stored in ustar-compatible archive
+entries that use the &lsquo;&lsquo;x&rsquo;&rsquo; or
+&lsquo;&lsquo;g&rsquo;&rsquo; typeflag. In particular, older
+implementations that do not fully support these extensions
+will extract the metadata into regular files, where the
+metadata can be examined as necessary.</p>
+
+<p style="margin-left:8%; margin-top: 1em">An entry in a
+pax interchange format archive consists of one or two
+standard ustar entries, each with its own header and data.
+The first optional entry stores the extended attributes for
+the following entry. This optional first entry has an
+&quot;x&quot; typeflag and a size field that indicates the
+total size of the extended attributes. The extended
+attributes themselves are stored as a series of text-format
+lines encoded in the portable UTF-8 encoding. Each line
+consists of a decimal number, a space, a key string, an
+equals sign, a value string, and a new line. The decimal
+number indicates the length of the entire line, including
+the initial length field and the trailing newline. An
+example of such a field is:</p>
+
+<p style="margin-left:17%;">25 ctime=1084839148.1212\n</p>
+
+<p style="margin-left:8%;">Keys in all lowercase are
+standard keys. Vendors can add their own keys by prefixing
+them with an all uppercase vendor name and a period. Note
+that, unlike the historic header, numeric values are stored
+using decimal, not octal. A description of some common keys
+follows:</p>
+
+<p style="margin-top: 1em" valign="top"><b>atime</b>,
+<b>ctime</b>, <b>mtime</b></p>
+
+<p style="margin-left:20%;">File access, inode change, and
+modification times. These fields can be negative or include
+a decimal point and a fractional value.</p>
+
+<p style="margin-top: 1em" valign="top"><b>uname</b>,
+<b>uid</b>, <b>gname</b>, <b>gid</b></p>
+
+<p style="margin-left:20%;">User name, group name, and
+numeric UID and GID values. The user name and group name
+stored here are encoded in UTF8 and can thus include
+non-ASCII characters. The UID and GID fields can be of
+arbitrary length.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>linkpath</b></p>
+
+<p style="margin-left:20%;">The full path of the linked-to

+non-ASCII characters.</p>
+
+<p style="margin-top: 1em" valign="top"><b>path</b></p>
+
+<p style="margin-left:20%; margin-top: 1em">The full

+
+<p style="margin-top: 1em" valign="top"><b>realtime.*</b>,

+
+<p style="margin-left:20%;">These keys are reserved and may
+be used for future standardization.</p>
+
+<p style="margin-top: 1em" valign="top"><b>size</b></p>
+
+<p style="margin-left:20%; margin-top: 1em">The size of the

+
+
+<p style="margin-top: 1em" valign="top"><b>SCHILY.acl.access</b>,

+
+<p style="margin-left:20%;">Stores the access and default
+ACLs as textual strings in a format that is an extension of
+the format specified by POSIX.1e draft 17. In particular,
+each user or group access specification can include a fourth

+
+<p style="margin-left:8%; margin-top: 1em">Any values
+stored in an extended attribute override the corresponding
+values in the regular tar header. Note that compliant
+readers should ignore the regular fields when they are
+overridden. This is important, as existing archivers are
+known to store non-compliant values in the standard header
+fields in this situation. There are no limits on length for
+any of these fields. In particular, numeric fields can be
+arbitrarily large. All text fields are encoded in UTF8.
+Compliant writers should store only portable 7-bit ASCII
+characters in the standard ustar header and use extended
+attributes whenever a text value contains non-ASCII
+characters.</p>
+
+<p style="margin-left:8%; margin-top: 1em">In addition to
+the <b>x</b> entry described above, the pax interchange
+format also supports a <b>g</b> entry. The <b>g</b> entry is
+identical in format, but specifies attributes that serve as
+defaults for all subsequent archive entries. The <b>g</b>
+entry is not widely used.</p>
+
+<p style="margin-left:8%; margin-top: 1em">Besides the new
+<b>x</b> and <b>g</b> entries, the pax interchange format
+has a few other minor variations from the earlier ustar
+format. The most troubling one is that hardlinks are
+permitted to have data following them. This allows readers
+to restore any hardlink to a file without having to rewind
+the archive to find an earlier entry. However, it creates
+complications for robust readers, as it is no longer clear
+whether or not they should ignore the size field for
+hardlink entries.</p>
+
+<p style="margin-left:8%; margin-top: 1em"><b>GNU Tar
+Archives</b> <br>
+The GNU tar program started with a pre-POSIX format similar
+to that described earlier and has extended it using several
+different mechanisms: It added new fields to the empty space
+in the header (some of which was later used by POSIX for
+conflicting purposes); it allowed the header to be continued
+over multiple records; and it defined new entries that
+modify following entries (similar in principle to the
+<b>x</b> entry described above, but each GNU special entry
+is single-purpose, unlike the general-purpose <b>x</b>
+entry). As a result, GNU tar archives are not POSIX
+compatible, although more lenient POSIX-compliant readers
+can successfully extract most GNU tar archives.</p>

+or &quot;N&quot; if the file is not stored in this archive.
+Each name is terminated with a null, and an extra null marks

+<p style="margin-left:20%;">A binary representation of the
+file&rsquo;s complete size, with a much larger range than
+the POSIX file size. In particular, with <b>M</b> type
+files, the current entry is only a portion of the file. In
+that case, the POSIX size field will indicate the size of
+this entry; the <i>realsize</i> field will indicate the
+total size of the file.</p>
+
+<p style="margin-left:8%; margin-top: 1em"><b>GNU tar pax
+archives</b> <br>
+GNU tar 1.14 (XXX check this XXX) and later will write pax
+interchange format archives when you specify the
+<b>&minus;-posix</b> flag. This format uses custom keywords
+to store sparse file information. There have been three
+iterations of this support, referred to as
+&lsquo;&lsquo;0.0&rsquo;&rsquo;,
+&lsquo;&lsquo;0.1&rsquo;&rsquo;, and
+&lsquo;&lsquo;1.0&rsquo;&rsquo;.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>GNU.sparse.numblocks</b>,
+<b>GNU.sparse.offset</b>, <b>GNU.sparse.numbytes</b>,
+<b>GNU.sparse.size</b></p>
+
+<p style="margin-left:20%;">The
+&lsquo;&lsquo;0.0&rsquo;&rsquo; format used an initial
+<b>GNU.sparse.numblocks</b> attribute to indicate the number
+of blocks in the file, a pair of <b>GNU.sparse.offset</b>
+and <b>GNU.sparse.numbytes</b> to indicate the offset and
+size of each block, and a single <b>GNU.sparse.size</b> to
+indicate the full size of the file. This is not the same as
+the size in the tar header because the latter value does not
+include the size of any holes. This format required that the
+order of attributes be preserved and relied on readers
+accepting multiple appearances of the same attribute names,
+which is not officially permitted by the standards.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>GNU.sparse.map</b></p>
+
+<p style="margin-left:20%;">The
+&lsquo;&lsquo;0.1&rsquo;&rsquo; format used a single
+attribute that stored a comma-separated list of decimal
+numbers. Each pair of numbers indicated the offset and size,
+respectively, of a block of data. This does not work well if
+the archive is extracted by an archiver that does not
+recognize this extension, since many pax implementations
+simply discard unrecognized attributes.</p>
+
+
+<p style="margin-top: 1em" valign="top"><b>GNU.sparse.major</b>,
+<b>GNU.sparse.minor</b>, <b>GNU.sparse.name</b>,
+<b>GNU.sparse.realsize</b></p>
+
+<p style="margin-left:20%;">The
+&lsquo;&lsquo;1.0&rsquo;&rsquo; format stores the sparse
+block map in one or more 512-byte blocks prepended to the
+file data in the entry body. The pax attributes indicate the
+existence of this map (via the <b>GNU.sparse.major</b> and
+<b>GNU.sparse.minor</b> fields) and the full size of the
+file. The <b>GNU.sparse.name</b> holds the true name of the
+file. To avoid confusion, the name stored in the regular tar
+header is a modified name so that extraction errors will be
+apparent to users.</p>
+
+<p style="margin-left:8%; margin-top: 1em"><b>Solaris
+Tar</b> <br>
+XXX More Details Needed XXX</p>
+
+<p style="margin-left:8%; margin-top: 1em">Solaris tar
+(beginning with SunOS XXX 5.7 ?? XXX) supports an
+&lsquo;&lsquo;extended&rsquo;&rsquo; format that is
+fundamentally similar to pax interchange format, with the
+following differences:</p>
+
+<p valign="top"><b>&bull;</b></p>
+
+<p style="margin-left:20%;">Extended attributes are stored
+in an entry whose type is <b>X</b>, not <b>x</b>, as used by
+pax interchange format. The detailed format of this entry
+appears to be the same as detailed above for the <b>x</b>
+entry.</p>
+
+<p valign="top"><b>&bull;</b></p>
+
+<p style="margin-left:20%;">An additional <b>A</b> entry is
+used to store an ACL for the following regular entry. The
+body of this entry contains a seven-digit octal number
+followed by a zero byte, followed by the textual ACL
+description. The octal value is the number of ACL entries
+plus a constant that indicates the ACL type: 01000000 for
+POSIX.1e ACLs and 03000000 for NFSv4 ACLs.</p>
+
+<p style="margin-left:8%; margin-top: 1em"><b>AIX Tar</b>
+<br>
+XXX More details needed XXX</p>
+
+<p style="margin-left:8%; margin-top: 1em"><b>Mac OS X
+Tar</b> <br>
+The tar distributed with Apple&rsquo;s Mac OS X stores most
+regular files as two separate entries in the tar archive.
+The two entries have the same name except that the first one
+has &lsquo;&lsquo;._&rsquo;&rsquo; added to the beginning of
+the name. This first entry stores the &lsquo;&lsquo;resource
+fork&rsquo;&rsquo; with additional attributes for the file.
+The Mac OS X <b>CopyFile</b>() API is used to separate a
+file on disk into separate resource and data streams and to
+reassemble those separate streams when the file is restored
+to disk.</p>
+
+<p style="margin-left:8%; margin-top: 1em"><b>Other
+Extensions</b> <br>
+One obvious extension to increase the size of files is to
+eliminate the terminating characters from the various
+numeric fields. For example, the standard only allows the
+size field to contain 11 octal digits, reserving the twelfth
+byte for a trailing NUL character. Allowing 12 octal digits
+allows file sizes up to 64 GB.</p>
+
+<p style="margin-left:8%; margin-top: 1em">Another
+extension, utilized by GNU tar, star, and other newer
+<b>tar</b> implementations, permits binary numbers in the
+standard numeric fields. This is flagged by setting the high
+bit of the first byte. This permits 95-bit values for the
+length and time fields and 63-bit values for the uid, gid,
+and device numbers. GNU tar supports this extension for the
+length, mtime, ctime, and atime fields. Joerg
+Schilling&rsquo;s star program supports this extension for
+all numeric fields. Note that this extension is largely
+obsoleted by the extended attribute record provided by the
+pax interchange format.</p>
+
+<p style="margin-left:8%; margin-top: 1em">Another early
+GNU extension allowed base-64 values rather than octal. This
+extension was short-lived and is no longer supported by any
+implementation.</p>

+
+
+<p style="margin-top: 1em" valign="top"><b>STANDARDS</b></p>
+
+<p style="margin-left:8%;">The <b>tar</b> utility is no
+longer a part of POSIX or the Single Unix Standard. It last
+appeared in Version&nbsp;2 of the Single UNIX Specification
+(&lsquo;&lsquo;SUSv2&rsquo;&rsquo;). It has been supplanted
+in subsequent standards by pax(1). The ustar format is
+currently part of the specification for the pax(1) utility.
+The pax interchange file format is new with IEEE Std
+1003.1-2001 (&lsquo;&lsquo;POSIX.1&rsquo;&rsquo;).</p>
+
+<p style="margin-top: 1em" valign="top"><b>HISTORY</b></p>
+
+<p style="margin-left:8%;">A <b>tar</b> command appeared in
+Seventh Edition Unix, which was released in January, 1979.
+It replaced the <b>tp</b> program from Fourth Edition Unix
+which in turn replaced the <b>tap</b> program from First
+Edition Unix. John Gilmore&rsquo;s <b>pdtar</b>
+public-domain implementation (circa 1987) was highly
+influential and formed the basis of <b>GNU tar</b> (circa
+1988). Joerg Shilling&rsquo;s <b>star</b> archiver is
+another open-source (GPL) archiver (originally developed
+circa 1985) which features complete support for pax
+interchange format.</p>

+.SH DESCRIPTION
+.ad l
+These functions create and manipulate data objects that
+represent entries within an archive.
+You can think of a
+Tn struct archive_entry
+as a heavy-duty version of
+Tn struct stat:
+it includes everything from
+Tn struct stat
+plus associated pathname, textual group and user names, etc.
+These objects are used by
+\fBlibarchive\fP(3)
+to represent the metadata associated with a particular
+entry in an archive.
+.SS Create and Destroy
+There are functions to allocate, destroy, clear, and copy
+\fIarchive_entry\fP
+objects:
+.RS 5
+.TP
+\fB\%archive_entry_clear\fP()
+Erases the object, resetting all internal fields to the
+same state as a newly-created object.
+This is provided to allow you to quickly recycle objects
+without thrashing the heap.
+.TP
+\fB\%archive_entry_clone\fP()
+A deep copy operation; all text fields are duplicated.
+.TP
+\fB\%archive_entry_free\fP()
+Releases the
+Tn struct archive_entry
+object.
+.TP
+\fB\%archive_entry_new\fP()
+Allocate and return a blank
+Tn struct archive_entry
+object.
+.RE
+.SS Set and Get Functions
+Most of the functions here set or read entries in an object.
+Such functions have one of the following forms:
+.RS 5
+.TP
+\fB\%archive_entry_set_XXXX\fP()
+Stores the provided data in the object.
+In particular, for strings, the pointer is stored,
+not the referenced string.
+.TP
+\fB\%archive_entry_copy_XXXX\fP()
+As above, except that the referenced data is copied
+into the object.
+.TP
+\fB\%archive_entry_XXXX\fP()
+Returns the specified data.
+In the case of strings, a const-qualified pointer to
+the string is returned.
+.RE
+String data can be set or accessed as wide character strings
+or normal
+\fIchar\fP
+strings.
+The functions that use wide character strings are suffixed with
+\fB_w\fP.
+Note that these are different representations of the same data:
+For example, if you store a narrow string and read the corresponding
+wide string, the object will transparently convert formats
+using the current locale.
+Similarly, if you store a wide string and then store a
+narrow string for the same data, the previously-set wide string will
+be discarded in favor of the new data.
+.PP
+There are a few set/get functions that merit additional description:
+.RS 5
+.TP
+\fB\%archive_entry_set_link\fP()
+This function sets the symlink field if it is already set.
+Otherwise, it sets the hardlink field.
+.RE
+.SS File Flags
+File flags are transparently converted between a bitmap
+representation and a textual format.
+For example, if you set the bitmap and ask for text, the library
+will build a canonical text format.
+However, if you set a text format and request a text format,
+you will get back the same text, even if it is ill-formed.
+If you need to canonicalize a textual flags string, you should first set the
+text form, then request the bitmap form, then use that to set the bitmap form.
+Setting the bitmap format will clear the internal text representation
+and force it to be reconstructed when you next request the text form.
+.PP
+The bitmap format consists of two integers, one containing bits
+that should be set, the other specifying bits that should be
+cleared.
+Bits not mentioned in either bitmap will be ignored.
+Usually, the bitmap of bits to be cleared will be set to zero.
+In unusual circumstances, you can force a fully-specified set
+of file flags by setting the bitmap of flags to clear to the complement
+of the bitmap of flags to set.
+(This differs from
+\fBfflagstostr\fP(3),
+which only includes names for set bits.)
+Converting a bitmap to a textual string is a platform-specific
+operation; bits that are not meaningful on the current platform
+will be ignored.
+.PP
+The canonical text format is a comma-separated list of flag names.
+The
+\fB\%archive_entry_copy_fflags_text\fP()
+and
+\fB\%archive_entry_copy_fflags_text_w\fP()
+functions parse the provided text and sets the internal bitmap values.
+This is a platform-specific operation; names that are not meaningful
+on the current platform will be ignored.
+The function returns a pointer to the start of the first name that was not
+recognized, or NULL if every name was recognized.
+Note that every name--including names that follow an unrecognized name--will
+be evaluated, and the bitmaps will be set to reflect every name that is
+recognized.
+(In particular, this differs from
+\fBstrtofflags\fP(3),
+which stops parsing at the first unrecognized name.)
+.SS ACL Handling
+XXX This needs serious help.
+XXX
+.PP
+An
+``Access Control List''
+(ACL) is a list of permissions that grant access to particular users or
+groups beyond what would normally be provided by standard POSIX mode bits.
+The ACL handling here addresses some deficiencies in the POSIX.1e draft 17 ACL
+specification.
+In particular, POSIX.1e draft 17 specifies several different formats, but
+none of those formats include both textual user/group names and numeric
+UIDs/GIDs.
+.PP
+XXX explain ACL stuff XXX

+.SH DESCRIPTION
+.ad l
+These functions provide a complete API for reading streaming archives.
+The general process is to first create the
+Tn struct archive
+object, set options, initialize the reader, iterate over the archive
+headers and associated data, then close the archive and release all
+resources.
+The following summary describes the functions in approximately the
+order they would be used:
+.RS 5
+.TP
+\fB\%archive_read_new\fP()
+Allocates and initializes a
+Tn struct archive
+object suitable for reading from an archive.
+.TP
+\fB\%archive_read_support_compression_bzip2\fP(),
+\fB\%archive_read_support_compression_compress\fP(),
+\fB\%archive_read_support_compression_gzip\fP(),
+\fB\%archive_read_support_compression_lzma\fP(),
+\fB\%archive_read_support_compression_none\fP(),
+\fB\%archive_read_support_compression_xz\fP()
+Enables auto-detection code and decompression support for the
+specified compression.
+Returns
+\fBARCHIVE_OK\fP
+if the compression is fully supported, or
+\fBARCHIVE_WARN\fP
+if the compression is supported only through an external program.
+Note that decompression using an external program is usually slower than
+decompression through built-in libraries.
+Note that
+``none''
+is always enabled by default.
+.TP
+\fB\%archive_read_support_compression_all\fP()
+Enables all available decompression filters.
+.TP
+\fB\%archive_read_support_compression_program\fP()
+Data is fed through the specified external program before being dearchived.
+Note that this disables automatic detection of the compression format,
+so it makes no sense to specify this in conjunction with any other
+decompression option.
+.TP
+\fB\%archive_read_support_compression_program_signature\fP()
+This feeds data through the specified external program
+but only if the initial bytes of the data match the specified
+signature value.
+.TP
+\fB\%archive_read_support_format_all\fP(),
+\fB\%archive_read_support_format_ar\fP(),
+\fB\%archive_read_support_format_cpio\fP(),
+\fB\%archive_read_support_format_empty\fP(),
+\fB\%archive_read_support_format_iso9660\fP(),
+\fB\%archive_read_support_format_mtree\fP(),
+\fB\%archive_read_support_format_tar\fP(),
+\fB\%archive_read_support_format_zip\fP()
+Enables support---including auto-detection code---for the
+specified archive format.
+For example,
+\fB\%archive_read_support_format_tar\fP()
+enables support for a variety of standard tar formats, old-style tar,
+ustar, pax interchange format, and many common variants.
+For convenience,
+\fB\%archive_read_support_format_all\fP()
+enables support for all available formats.
+Only empty archives are supported by default.
+.TP
+\fB\%archive_read_support_format_raw\fP()
+The
+``raw''
+format handler allows libarchive to be used to read arbitrary data.
+It treats any data stream as an archive with a single entry.
+The pathname of this entry is
+``data ;''
+all other entry fields are unset.
+This is not enabled by
+\fB\%archive_read_support_format_all\fP()
+in order to avoid erroneous handling of damaged archives.
+.TP
+\fB\%archive_read_set_filter_options\fP(),
+\fB\%archive_read_set_format_options\fP(),
+\fB\%archive_read_set_options\fP()
+Specifies options that will be passed to currently-registered
+filters (including decompression filters) and/or format readers.
+The argument is a comma-separated list of individual options.
+Individual options have one of the following forms:
+.RS 5
+.TP
+\fIoption=value\fP
+The option/value pair will be provided to every module.
+Modules that do not accept an option with this name will ignore it.
+.TP
+\fIoption\fP
+The option will be provided to every module with a value of
+``1''.
+.TP
+\fI!option\fP
+The option will be provided to every module with a NULL value.
+.TP
+\fImodule:option=value\fP, \fImodule:option\fP, \fImodule:!option\fP
+As above, but the corresponding option and value will be provided
+only to modules whose name matches
+\fImodule\fP.
+.RE
+The return value will be
+\fBARCHIVE_OK\fP
+if any module accepts the option, or
+\fBARCHIVE_WARN\fP
+if no module accepted the option, or
+\fBARCHIVE_FATAL\fP
+if there was a fatal error while attempting to process the option.
+.PP
+The currently supported options are:
+.RS 5
+.TP
+Format iso9660
+.RS 5
+.TP
+\fBjoliet\fP
+Support Joliet extensions.
+Defaults to enabled, use
+\fB!joliet\fP
+to disable.
+.RE
+.RE
+.TP
+\fB\%archive_read_open\fP()
+The same as
+\fB\%archive_read_open2\fP(),
+except that the skip callback is assumed to be
+.BR NULL.
+.TP
+\fB\%archive_read_open2\fP()
+Freeze the settings, open the archive, and prepare for reading entries.
+This is the most generic version of this call, which accepts
+four callback functions.
+Most clients will want to use
+\fB\%archive_read_open_filename\fP(),
+\fB\%archive_read_open_FILE\fP(),
+\fB\%archive_read_open_fd\fP(),
+or
+\fB\%archive_read_open_memory\fP()
+instead.
+The library invokes the client-provided functions to obtain
+raw bytes from the archive.
+.TP
+\fB\%archive_read_open_FILE\fP()
+Like
+\fB\%archive_read_open\fP(),
+except that it accepts a
+\fIFILE *\fP
+pointer.
+This function should not be used with tape drives or other devices
+that require strict I/O blocking.
+.TP
+\fB\%archive_read_open_fd\fP()
+Like
+\fB\%archive_read_open\fP(),
+except that it accepts a file descriptor and block size rather than
+a set of function pointers.
+Note that the file descriptor will not be automatically closed at
+end-of-archive.
+This function is safe for use with tape drives or other blocked devices.
+.TP
+\fB\%archive_read_open_file\fP()
+This is a deprecated synonym for
+\fB\%archive_read_open_filename\fP().
+.TP
+\fB\%archive_read_open_filename\fP()
+Like
+\fB\%archive_read_open\fP(),
+except that it accepts a simple filename and a block size.
+A NULL filename represents standard input.
+This function is safe for use with tape drives or other blocked devices.
+.TP
+\fB\%archive_read_open_memory\fP()
+Like
+\fB\%archive_read_open\fP(),
+except that it accepts a pointer and size of a block of
+memory containing the archive data.
+.TP
+\fB\%archive_read_next_header\fP()
+Read the header for the next entry and return a pointer to
+a
+Tn struct archive_entry.
+This is a convenience wrapper around
+\fB\%archive_read_next_header2\fP()
+that reuses an internal
+Tn struct archive_entry
+object for each request.
+.TP
+\fB\%archive_read_next_header2\fP()
+Read the header for the next entry and populate the provided
+Tn struct archive_entry.
+.TP
+\fB\%archive_read_data\fP()
+Read data associated with the header just read.
+Internally, this is a convenience function that calls
+\fB\%archive_read_data_block\fP()
+and fills any gaps with nulls so that callers see a single
+continuous stream of data.
+.TP
+\fB\%archive_read_data_block\fP()
+Return the next available block of data for this entry.
+Unlike
+\fB\%archive_read_data\fP(),
+the
+\fB\%archive_read_data_block\fP()
+function avoids copying data and allows you to correctly handle
+sparse files, as supported by some archive formats.
+The library guarantees that offsets will increase and that blocks
+will not overlap.
+Note that the blocks returned from this function can be much larger
+than the block size read from disk, due to compression
+and internal buffer optimizations.
+.TP
+\fB\%archive_read_data_skip\fP()
+A convenience function that repeatedly calls
+\fB\%archive_read_data_block\fP()
+to skip all of the data for this archive entry.
+.TP
+\fB\%archive_read_data_into_buffer\fP()
+This function is deprecated and will be removed.
+Use
+\fB\%archive_read_data\fP()
+instead.
+.TP
+\fB\%archive_read_data_into_fd\fP()
+A convenience function that repeatedly calls
+\fB\%archive_read_data_block\fP()
+to copy the entire entry to the provided file descriptor.
+.TP
+\fB\%archive_read_extract\fP(), \fB\%archive_read_extract_set_skip_file\fP()
+A convenience function that wraps the corresponding
+\fBarchive_write_disk\fP(3)
+interfaces.
+The first call to
+\fB\%archive_read_extract\fP()
+creates a restore object using
+\fBarchive_write_disk_new\fP(3)
+and
+\fBarchive_write_disk_set_standard_lookup\fP(3),
+then transparently invokes
+\fBarchive_write_disk_set_options\fP(3),
+\fBarchive_write_header\fP(3),
+\fBarchive_write_data\fP(3),
+and
+\fBarchive_write_finish_entry\fP(3)
+to create the entry on disk and copy data into it.
+The
+\fIflags\fP
+argument is passed unmodified to
+\fBarchive_write_disk_set_options\fP(3).
+.TP
+\fB\%archive_read_extract2\fP()
+This is another version of
+\fB\%archive_read_extract\fP()
+that allows you to provide your own restore object.
+In particular, this allows you to override the standard lookup functions
+using
+\fBarchive_write_disk_set_group_lookup\fP(3),
+and
+\fBarchive_write_disk_set_user_lookup\fP(3).
+Note that
+\fB\%archive_read_extract2\fP()
+does not accept a
+\fIflags\fP
+argument; you should use
+\fB\%archive_write_disk_set_options\fP()
+to set the restore options yourself.
+.TP
+\fB\%archive_read_extract_set_progress_callback\fP()
+Sets a pointer to a user-defined callback that can be used
+for updating progress displays during extraction.
+The progress function will be invoked during the extraction of large
+regular files.
+The progress function will be invoked with the pointer provided to this call.
+Generally, the data pointed to should include a reference to the archive
+object and the archive_entry object so that various statistics
+can be retrieved for the progress display.
+.TP
+\fB\%archive_read_close\fP()
+Complete the archive and invoke the close callback.
+.TP
+\fB\%archive_read_finish\fP()
+Invokes
+\fB\%archive_read_close\fP()
+if it was not invoked manually, then release all resources.
+Note: In libarchive 1.x, this function was declared to return
+\fIvoid ,\fP
+which made it impossible to detect certain errors when
+\fB\%archive_read_close\fP()
+was invoked implicitly from this function.
+The declaration is corrected beginning with libarchive 2.0.
+.RE
+.PP
+Note that the library determines most of the relevant information about
+the archive by inspection.
+In particular, it automatically detects
+\fBgzip\fP(1)
+or
+\fBbzip2\fP(1)
+compression and transparently performs the appropriate decompression.
+It also automatically detects the archive format.

+Tn struct archive
+and
+Tn struct archive_entry
+objects can be found in the overview manual page for
+\fBlibarchive\fP(3).
+.SH CLIENT CALLBACKS
+.ad l
+The callback functions must match the following prototypes:
+.RS 5
+.IP
+\fItypedef ssize_t\fP
+\fB\%archive_read_callback\fP(\fI\%struct\ archive\ *\fP, \fI\%void\ *client_data\fP, \fI\%const\ void\ **buffer\fP)
+.IP
+\fItypedef int\fP
+\fB\%archive_skip_callback\fP(\fI\%struct\ archive\ *\fP, \fI\%void\ *client_data\fP, \fI\%size_t\ request\fP)
+.IP
+\fItypedef int\fP
+\fB\%archive_open_callback\fP(\fI\%struct\ archive\ *\fP, \fI\%void\ *client_data\fP)
+.IP
+\fItypedef int\fP
+\fB\%archive_close_callback\fP(\fI\%struct\ archive\ *\fP, \fI\%void\ *client_data\fP)
+.RE
+.PP
+The open callback is invoked by
+\fB\%archive_open\fP().
+It should return
+\fBARCHIVE_OK\fP
+if the underlying file or data source is successfully
+opened.
+If the open fails, it should call
+\fB\%archive_set_error\fP()
+to register an error code and message and return
+\fBARCHIVE_FATAL\fP.
+.PP
+The read callback is invoked whenever the library
+requires raw bytes from the archive.
+The read callback should read data into a buffer,
+set the
+.RS 4
+const void **buffer
+.RE
+argument to point to the available data, and
+return a count of the number of bytes available.
+The library will invoke the read callback again
+only after it has consumed this data.
+The library imposes no constraints on the size
+of the data blocks returned.
+On end-of-file, the read callback should
+return zero.
+On error, the read callback should invoke
+\fB\%archive_set_error\fP()
+to register an error code and message and
+return -1.
+.PP
+The skip callback is invoked when the
+library wants to ignore a block of data.
+The return value is the number of bytes actually
+skipped, which may differ from the request.
+If the callback cannot skip data, it should return
+zero.
+If the skip callback is not provided (the
+function pointer is
+.BR NULL ),
+the library will invoke the read function
+instead and simply discard the result.
+A skip callback can provide significant
+performance gains when reading uncompressed
+archives from slow disk drives or other media
+that can skip quickly.
+.PP
+The close callback is invoked by archive_close when
+the archive processing is complete.
+The callback should return
+\fBARCHIVE_OK\fP
+on success.
+On failure, the callback should invoke
+\fB\%archive_set_error\fP()
+to register an error code and message and
+return
+\fBARCHIVE_FATAL.\fP
+.SH EXAMPLE
+.ad l
+The following illustrates basic usage of the library.
+In this example,
+the callback functions are simply wrappers around the standard
+\fBopen\fP(2),
+\fBread\fP(2),
+and
+\fBclose\fP(2)
+system calls.

+.RE
+.SH RETURN VALUES
+.ad l
+Most functions return zero on success, non-zero on error.
+The possible return codes include:
+\fBARCHIVE_OK\fP
+(the operation succeeded),
+\fBARCHIVE_WARN\fP
+(the operation succeeded but a non-critical error was encountered),
+\fBARCHIVE_EOF\fP
+(end-of-archive was encountered),
+\fBARCHIVE_RETRY\fP
+(the operation failed but can be retried),
+and
+\fBARCHIVE_FATAL\fP
+(there was a fatal error; the archive should be closed immediately).
+Detailed error codes and textual descriptions are available from the
+\fB\%archive_errno\fP()
+and
+\fB\%archive_error_string\fP()
+functions.
+.PP
+\fB\%archive_read_new\fP()
+returns a pointer to a freshly allocated
+Tn struct archive
+object.
+It returns
+.BR NULL
+on error.
+.PP
+\fB\%archive_read_data\fP()
+returns a count of bytes actually read or zero at the end of the entry.
+On error, a value of
+\fBARCHIVE_FATAL\fP,
+\fBARCHIVE_WARN\fP,
+or
+\fBARCHIVE_RETRY\fP
+is returned and an error code and textual description can be retrieved from the
+\fB\%archive_errno\fP()
+and
+\fB\%archive_error_string\fP()
+functions.
+.PP
+The library expects the client callbacks to behave similarly.
+If there is an error, you can use
+\fB\%archive_set_error\fP()
+to set an appropriate error code and description,
+then return one of the non-zero values above.
+(Note that the value eventually returned to the client may
+not be the same; many errors that are not critical at the level
+of basic I/O can prevent the archive from being properly read,
+thus most I/O errors eventually cause
+\fBARCHIVE_FATAL\fP
+to be returned.)

+.SH DESCRIPTION
+.ad l
+These functions provide an API for reading information about
+objects on disk.
+In particular, they provide an interface for populating
+Tn struct archive_entry
+objects.
+.RS 5
+.TP
+\fB\%archive_read_disk_new\fP()
+Allocates and initializes a
+Tn struct archive
+object suitable for reading object information from disk.
+.TP
+\fB\%archive_read_disk_set_symlink_logical\fP(),
+\fB\%archive_read_disk_set_symlink_physical\fP(),
+\fB\%archive_read_disk_set_symlink_hybrid\fP()
+This sets the mode used for handling symbolic links.
+The
+``logical''
+mode follows all symbolic links.
+The
+``physical''
+mode does not follow any symbolic links.
+The
+``hybrid''
+mode currently behaves identically to the
+``logical''
+mode.
+.TP
+\fB\%archive_read_disk_gname\fP(),
+\fB\%archive_read_disk_uname\fP()
+Returns a user or group name given a gid or uid value.
+By default, these always return a NULL string.
+.TP
+\fB\%archive_read_disk_set_gname_lookup\fP(),
+\fB\%archive_read_disk_set_uname_lookup\fP()
+These allow you to override the functions used for
+user and group name lookups.
+You may also provide a
+Tn void *
+pointer to a private data structure and a cleanup function for
+that data.
+The cleanup function will be invoked when the
+Tn struct archive
+object is destroyed or when new lookup functions are registered.
+.TP
+\fB\%archive_read_disk_set_standard_lookup\fP()
+This convenience function installs a standard set of user
+and group name lookup functions.
+These functions use
+\fBgetpwid\fP(3)
+and
+\fBgetgrid\fP(3)
+to convert ids to names, defaulting to NULL if the names cannot
+be looked up.
+These functions also implement a simple memory cache to reduce
+the number of calls to
+\fBgetpwid\fP(3)
+and
+\fBgetgrid\fP(3).
+.TP
+\fB\%archive_read_disk_entry_from_file\fP()
+Populates a
+Tn struct archive_entry
+object with information about a particular file.
+The
+Tn archive_entry
+object must have already been created with
+\fBarchive_entry_new\fP(3)
+and at least one of the source path or path fields must already be set.
+(If both are set, the source path will be used.)
+.PP
+Information is read from disk using the path name from the
+Tn struct archive_entry
+object.
+If a file descriptor is provided, some information will be obtained using
+that file descriptor, on platforms that support the appropriate
+system calls.
+.PP
+If a pointer to a
+Tn struct stat
+is provided, information from that structure will be used instead
+of reading from the disk where appropriate.
+This can provide performance benefits in scenarios where
+Tn struct stat
+information has already been read from the disk as a side effect
+of some other operation.
+(For example, directory traversal libraries often provide this information.)
+.PP
+Where necessary, user and group ids are converted to user and group names
+using the currently registered lookup functions above.
+This affects the file ownership fields and ACL values in the
+Tn struct archive_entry
+object.
+.TP
+\fB\%archive_read_close\fP()
+This currently does nothing.
+.TP
+\fB\%archive_write_finish\fP()
+Invokes
+\fB\%archive_write_close\fP()
+if it was not invoked manually, then releases all resources.
+.RE
+More information about the
+\fIstruct\fP archive
+object and the overall design of the library can be found in the
+\fBlibarchive\fP(3)
+overview.

+.RE
+.SH RETURN VALUES
+.ad l
+Most functions return
+\fBARCHIVE_OK\fP
+(zero) on success, or one of several negative
+error codes for errors.
+Specific error codes include:
+\fBARCHIVE_RETRY\fP
+for operations that might succeed if retried,
+\fBARCHIVE_WARN\fP
+for unusual conditions that do not prevent further operations, and
+\fBARCHIVE_FATAL\fP
+for serious errors that make remaining operations impossible.
+The
+\fBarchive_errno\fP(3)
+and
+\fBarchive_error_string\fP(3)
+functions can be used to retrieve an appropriate error code and a
+textual error message.
+(See
+\fBarchive_util\fP(3)
+for details.)
+.PP
+\fB\%archive_read_disk_new\fP()
+returns a pointer to a newly-allocated
+Tn struct archive
+object or NULL if the allocation failed for any reason.
+.PP
+\fB\%archive_read_disk_gname\fP()
+and
+\fB\%archive_read_disk_uname\fP()

+callers should copy the string if they need to continue accessing it.

+function reads as much information as it can from disk.
+Some method should be provided to limit this so that clients who

+object used in the
+\fBlibarchive\fP(3)
+library.
+.RS 5
+.TP
+\fB\%archive_clear_error\fP()
+Clears any error information left over from a previous call.
+Not generally used in client code.
+.TP
+\fB\%archive_compression\fP()
+Returns a numeric code indicating the current compression.
+This value is set by
+\fB\%archive_read_open\fP().
+.TP
+\fB\%archive_compression_name\fP()
+Returns a text description of the current compression suitable for display.
+.TP
+\fB\%archive_copy_error\fP()
+Copies error information from one archive to another.
+.TP
+\fB\%archive_errno\fP()
+Returns a numeric error code (see
+\fBerrno\fP(2))
+indicating the reason for the most recent error return.
+.TP
+\fB\%archive_error_string\fP()
+Returns a textual error message suitable for display.
+The error message here is usually more specific than that
+obtained from passing the result of
+\fB\%archive_errno\fP()
+to
+\fBstrerror\fP(3).
+.TP
+\fB\%archive_file_count\fP()
+Returns a count of the number of files processed by this archive object.
+The count is incremented by calls to
+\fBarchive_write_header\fP()
+or
+\fBarchive_read_next_header\fP(.)
+.TP
+\fB\%archive_format\fP()
+Returns a numeric code indicating the format of the current
+archive entry.
+This value is set by a successful call to
+\fB\%archive_read_next_header\fP().
+Note that it is common for this value to change from
+entry to entry.
+For example, a tar archive might have several entries that
+utilize GNU tar extensions and several entries that do not.
+These entries will have different format codes.
+.TP
+\fB\%archive_format_name\fP()
+A textual description of the format of the current entry.
+.TP
+\fB\%archive_set_error\fP()
+Sets the numeric error code and error description that will be returned
+by
+\fB\%archive_errno\fP()
+and
+\fB\%archive_error_string\fP().
+This function should be used within I/O callbacks to set system-specific
+error codes and error descriptions.
+This function accepts a printf-like format string and arguments.
+However, you should be careful to use only the following printf
+format specifiers:
+``%c'',
+``%d'',
+``%jd'',
+``%jo'',
+``%ju'',
+``%jx'',
+``%ld'',
+``%lo'',

+.SH DESCRIPTION
+.ad l
+These functions provide a complete API for creating streaming
+archive files.
+The general process is to first create the
+Tn struct archive
+object, set any desired options, initialize the archive, append entries, then
+close the archive and release all resources.
+The following summary describes the functions in approximately
+the order they are ordinarily used:
+.RS 5
+.TP
+\fB\%archive_write_new\fP()
+Allocates and initializes a
+Tn struct archive
+object suitable for writing a tar archive.
+.TP
+\fB\%archive_write_set_bytes_per_block\fP()
+Sets the block size used for writing the archive data.
+Every call to the write callback function, except possibly the last one, will
+use this value for the length.
+The third parameter is a boolean that specifies whether or not the final block
+written will be padded to the full block size.
+If it is zero, the last block will not be padded.
+If it is non-zero, padding will be added both before and after compression.
+The default is to use a block size of 10240 bytes and to pad the last block.
+Note that a block size of zero will suppress internal blocking
+and cause writes to be sent directly to the write callback as they occur.
+.TP
+\fB\%archive_write_get_bytes_per_block\fP()
+Retrieve the block size to be used for writing.
+A value of -1 here indicates that the library should use default values.
+A value of zero indicates that internal blocking is suppressed.
+.TP
+\fB\%archive_write_set_bytes_in_last_block\fP()
+Sets the block size used for writing the last block.
+If this value is zero, the last block will be padded to the same size
+as the other blocks.
+Otherwise, the final block will be padded to a multiple of this size.
+In particular, setting it to 1 will cause the final block to not be padded.
+For compressed output, any padding generated by this option
+is applied only after the compression.
+The uncompressed data is always unpadded.
+The default is to pad the last block to the full block size (note that
+\fB\%archive_write_open_filename\fP()
+will set this based on the file type).
+Unlike the other
+``set''
+functions, this function can be called after the archive is opened.
+.TP
+\fB\%archive_write_get_bytes_in_last_block\fP()
+Retrieve the currently-set value for last block size.
+A value of -1 here indicates that the library should use default values.
+.TP
+\fB\%archive_write_set_format_cpio\fP(),
+\fB\%archive_write_set_format_pax\fP(),
+\fB\%archive_write_set_format_pax_restricted\fP(),
+\fB\%archive_write_set_format_shar\fP(),
+\fB\%archive_write_set_format_shar_binary\fP(),
+\fB\%archive_write_set_format_ustar\fP()
+Sets the format that will be used for the archive.
+The library can write
+POSIX octet-oriented cpio format archives,
+POSIX-standard
+``pax interchange''
+format archives,
+traditional
+``shar''
+archives,
+enhanced
+``binary''
+shar archives that store a variety of file attributes and handle binary files,
+and
+POSIX-standard
+``ustar''
+archives.
+The pax interchange format is a backwards-compatible tar format that
+adds key/value attributes to each entry and supports arbitrary
+filenames, linknames, uids, sizes, etc.
+``Restricted pax interchange format''
+is the library default; this is the same as pax format, but suppresses
+the pax extended header for most normal files.
+In most cases, this will result in ordinary ustar archives.
+.TP
+\fB\%archive_write_set_compression_bzip2\fP(),
+\fB\%archive_write_set_compression_compress\fP(),
+\fB\%archive_write_set_compression_gzip\fP(),
+\fB\%archive_write_set_compression_none\fP()
+The resulting archive will be compressed as specified.
+Note that the compressed output is always properly blocked.
+.TP
+\fB\%archive_write_set_compression_program\fP()
+The archive will be fed into the specified compression program.
+The output of that program is blocked and written to the client
+write callbacks.
+.TP
+\fB\%archive_write_set_compressor_options\fP(),
+\fB\%archive_write_set_format_options\fP(),
+\fB\%archive_write_set_options\fP()
+Specifies options that will be passed to the currently-enabled
+compressor and/or format writer.
+The argument is a comma-separated list of individual options.
+Individual options have one of the following forms:
+.RS 5
+.TP
+\fIoption=value\fP
+The option/value pair will be provided to every module.
+Modules that do not accept an option with this name will ignore it.
+.TP
+\fIoption\fP
+The option will be provided to every module with a value of
+``1''.
+.TP
+\fI!option\fP
+The option will be provided to every module with a NULL value.
+.TP
+\fImodule:option=value\fP, \fImodule:option\fP, \fImodule:!option\fP
+As above, but the corresponding option and value will be provided
+only to modules whose name matches
+\fImodule\fP.
+.RE
+The return value will be
+\fBARCHIVE_OK\fP
+if any module accepts the option, or
+\fBARCHIVE_WARN\fP
+if no module accepted the option, or
+\fBARCHIVE_FATAL\fP
+if there was a fatal error while attempting to process the option.
+.PP
+The currently supported options are:
+.RS 5
+.TP
+Compressor gzip
+.RS 5
+.TP
+\fBcompression-level\fP
+The value is interpreted as a decimal integer specifying the
+gzip compression level.
+.RE
+.TP
+Compressor xz
+.RS 5
+.TP
+\fBcompression-level\fP
+The value is interpreted as a decimal integer specifying the
+compression level.
+.RE
+.TP
+Format mtree
+.RS 5
+.TP
+\fBcksum\fP, \fBdevice\fP, \fBflags\fP, \fBgid\fP, \fBgname\fP, \fBindent\fP, \fBlink\fP, \fBmd5\fP, \fBmode\fP, \fBnlink\fP, \fBrmd160\fP, \fBsha1\fP, \fBsha256\fP, \fBsha384\fP, \fBsha512\fP, \fBsize\fP, \fBtime\fP, \fBuid\fP, \fBuname\fP
+Enable a particular keyword in the mtree output.
+Prefix with an exclamation mark to disable the corresponding keyword.
+The default is equivalent to
+``device, flags, gid, gname, link, mode, nlink, size, time, type, uid, uname''.
+.TP
+\fBall\fP
+Enables all of the above keywords.
+.TP
+\fBuse-set\fP
+Enables generation of
+\fB/set\fP
+lines that specify default values for the following files and/or directories.
+.TP
+\fBindent\fP
+XXX needs explanation XXX
+.RE
+.RE
+.TP
+\fB\%archive_write_open\fP()
+Freeze the settings, open the archive, and prepare for writing entries.
+This is the most generic form of this function, which accepts
+pointers to three callback functions which will be invoked by
+the compression layer to write the constructed archive.
+.TP
+\fB\%archive_write_open_fd\fP()
+A convenience form of
+\fB\%archive_write_open\fP()
+that accepts a file descriptor.
+The
+\fB\%archive_write_open_fd\fP()
+function is safe for use with tape drives or other
+block-oriented devices.
+.TP
+\fB\%archive_write_open_FILE\fP()
+A convenience form of
+\fB\%archive_write_open\fP()
+that accepts a
+\fIFILE *\fP
+pointer.
+Note that
+\fB\%archive_write_open_FILE\fP()
+is not safe for writing to tape drives or other devices
+that require correct blocking.
+.TP
+\fB\%archive_write_open_file\fP()
+A deprecated synonym for
+\fB\%archive_write_open_filename\fP().
+.TP
+\fB\%archive_write_open_filename\fP()
+A convenience form of
+\fB\%archive_write_open\fP()
+that accepts a filename.
+A NULL argument indicates that the output should be written to standard output;
+an argument of
+``-''
+will open a file with that name.
+If you have not invoked
+\fB\%archive_write_set_bytes_in_last_block\fP(),
+then
+\fB\%archive_write_open_filename\fP()
+will adjust the last-block padding depending on the file:
+it will enable padding when writing to standard output or
+to a character or block device node, it will disable padding otherwise.
+You can override this by manually invoking
+\fB\%archive_write_set_bytes_in_last_block\fP()
+before calling
+\fB\%archive_write_open\fP().
+The
+\fB\%archive_write_open_filename\fP()
+function is safe for use with tape drives or other
+block-oriented devices.
+.TP
+\fB\%archive_write_open_memory\fP()
+A convenience form of
+\fB\%archive_write_open\fP()
+that accepts a pointer to a block of memory that will receive
+the archive.
+The final
+\fIsize_t *\fP
+argument points to a variable that will be updated
+after each write to reflect how much of the buffer
+is currently in use.
+You should be careful to ensure that this variable
+remains allocated until after the archive is
+closed.
+.TP
+\fB\%archive_write_header\fP()
+Build and write a header using the data in the provided
+Tn struct archive_entry
+structure.
+See
+\fBarchive_entry\fP(3)
+for information on creating and populating
+Tn struct archive_entry
+objects.
+.TP
+\fB\%archive_write_data\fP()
+Write data corresponding to the header just written.
+Returns number of bytes written or -1 on error.
+.TP
+\fB\%archive_write_finish_entry\fP()
+Close out the entry just written.
+In particular, this writes out the final padding required by some formats.
+Ordinarily, clients never need to call this, as it
+is called automatically by
+\fB\%archive_write_next_header\fP()
+and
+\fB\%archive_write_close\fP()
+as needed.
+.TP
+\fB\%archive_write_close\fP()
+Complete the archive and invoke the close callback.
+.TP
+\fB\%archive_write_finish\fP()
+Invokes
+\fB\%archive_write_close\fP()
+if it was not invoked manually, then releases all resources.
+Note that this function was declared to return
+\fIvoid\fP
+in libarchive 1.x, which made it impossible to detect errors when
+\fB\%archive_write_close\fP()
+was invoked implicitly from this function.
+This is corrected beginning with libarchive 2.0.
+.RE
+More information about the
+\fIstruct\fP archive
+object and the overall design of the library can be found in the
+\fBlibarchive\fP(3)
+overview.
+.SH IMPLEMENTATION
+.ad l
+Compression support is built-in to libarchive, which uses zlib and bzlib
+to handle gzip and bzip2 compression, respectively.
+.SH CLIENT CALLBACKS
+.ad l
+To use this library, you will need to define and register
+callback functions that will be invoked to write data to the
+resulting archive.
+These functions are registered by calling
+\fB\%archive_write_open\fP():
+.RS 5
+.IP
+\fItypedef int\fP
+\fB\%archive_open_callback\fP(\fI\%struct\ archive\ *\fP, \fI\%void\ *client_data\fP)
+.RE
+.PP
+The open callback is invoked by
+\fB\%archive_write_open\fP().
+It should return
+\fBARCHIVE_OK\fP
+if the underlying file or data source is successfully
+opened.
+If the open fails, it should call
+\fB\%archive_set_error\fP()
+to register an error code and message and return
+\fBARCHIVE_FATAL\fP.
+.RS 5
+.IP
+\fItypedef ssize_t\fP
+\fB\%archive_write_callback\fP(\fI\%struct\ archive\ *\fP, \fI\%void\ *client_data\fP, \fI\%const\ void\ *buffer\fP, \fI\%size_t\ length\fP)
+.RE
+.PP
+The write callback is invoked whenever the library
+needs to write raw bytes to the archive.
+For correct blocking, each call to the write callback function
+should translate into a single
+\fBwrite\fP(2)
+system call.
+This is especially critical when writing archives to tape drives.
+On success, the write callback should return the
+number of bytes actually written.
+On error, the callback should invoke
+\fB\%archive_set_error\fP()
+to register an error code and message and return -1.
+.RS 5
+.IP
+\fItypedef int\fP
+\fB\%archive_close_callback\fP(\fI\%struct\ archive\ *\fP, \fI\%void\ *client_data\fP)
+.RE
+.PP
+The close callback is invoked by archive_close when
+the archive processing is complete.
+The callback should return
+\fBARCHIVE_OK\fP
+on success.
+On failure, the callback should invoke
+\fB\%archive_set_error\fP()
+to register an error code and message and
+return
+\fBARCHIVE_FATAL.\fP
+.SH EXAMPLE
+.ad l
+The following sketch illustrates basic usage of the library.
+In this example,
+the callback functions are simply wrappers around the standard
+\fBopen\fP(2),
+\fBwrite\fP(2),
+and
+\fBclose\fP(2)
+system calls.

+.SH RETURN VALUES
+.ad l
+Most functions return
+\fBARCHIVE_OK\fP
+(zero) on success, or one of several non-zero
+error codes for errors.
+Specific error codes include:
+\fBARCHIVE_RETRY\fP
+for operations that might succeed if retried,
+\fBARCHIVE_WARN\fP
+for unusual conditions that do not prevent further operations, and
+\fBARCHIVE_FATAL\fP
+for serious errors that make remaining operations impossible.
+The
+\fB\%archive_errno\fP()
+and
+\fB\%archive_error_string\fP()
+functions can be used to retrieve an appropriate error code and a
+textual error message.
+.PP
+\fB\%archive_write_new\fP()
+returns a pointer to a newly-allocated
+Tn struct archive
+object.
+.PP
+\fB\%archive_write_data\fP()
+returns a count of the number of bytes actually written.
+On error, -1 is returned and the
+\fB\%archive_errno\fP()
+and
+\fB\%archive_error_string\fP()
+functions will return appropriate values.
+Note that if the client-provided write callback function
+returns a non-zero value, that error will be propagated back to the caller
+through whatever API function resulted in that call, which
+may include
+\fB\%archive_write_header\fP(),
+\fB\%archive_write_data\fP(),
+\fB\%archive_write_close\fP(),
+or
+\fB\%archive_write_finish\fP().
+The client callback can call
+\fB\%archive_set_error\fP()

+\fB\%archive_errno\fP()
+and
+\fB\%archive_error_string\fP().

+The
+\fB\%libarchive\fP
+library was written by
+Tim Kientzle \%<kientzle@acm.org.>
+.SH BUGS
+.ad l
+There are many peculiar bugs in historic tar implementations that may cause
+certain programs to reject archives written by this library.
+For example, several historic implementations calculated header checksums
+incorrectly and will thus reject valid archives; GNU tar does not fully support
+pax interchange format; some old tar implementations required specific
+field terminations.
+.PP
+The default pax interchange format eliminates most of the historic
+tar limitations and provides a generic key/value attribute facility
+for vendor-defined extensions.
+One oversight in POSIX is the failure to provide a standard attribute
+for large device numbers.
+This library uses
+``SCHILY.devminor''
+and
+``SCHILY.devmajor''
+for device numbers that exceed the range supported by the backwards-compatible
+ustar header.
+These keys are compatible with Joerg Schilling's
+\fB\%star\fP
+archiver.
+Other implementations may not recognize these keys and will thus be unable
+to correctly restore device nodes with large device numbers from archives
+created by this library.

+.SH DESCRIPTION
+.ad l
+These functions provide a complete API for creating objects on
+disk from
+Tn struct archive_entry
+descriptions.
+They are most naturally used when extracting objects from an archive
+using the
+\fB\%archive_read\fP()
+interface.
+The general process is to read
+Tn struct archive_entry
+objects from an archive, then write those objects to a
+Tn struct archive
+object created using the
+\fB\%archive_write_disk\fP()
+family functions.
+This interface is deliberately very similar to the
+\fB\%archive_write\fP()
+interface used to write objects to a streaming archive.
+.RS 5
+.TP
+\fB\%archive_write_disk_new\fP()
+Allocates and initializes a
+Tn struct archive
+object suitable for writing objects to disk.
+.TP
+\fB\%archive_write_disk_set_skip_file\fP()
+Records the device and inode numbers of a file that should not be
+overwritten.
+This is typically used to ensure that an extraction process does not
+overwrite the archive from which objects are being read.
+This capability is technically unnecessary but can be a significant
+performance optimization in practice.
+.TP
+\fB\%archive_write_disk_set_options\fP()
+The options field consists of a bitwise OR of one or more of the
+following values:
+.RS 5
+.TP
+\fBARCHIVE_EXTRACT_OWNER\fP
+The user and group IDs should be set on the restored file.
+By default, the user and group IDs are not restored.
+.TP
+\fBARCHIVE_EXTRACT_PERM\fP
+Full permissions (including SGID, SUID, and sticky bits) should
+be restored exactly as specified, without obeying the
+current umask.
+Note that SUID and SGID bits can only be restored if the
+user and group ID of the object on disk are correct.
+If
+\fBARCHIVE_EXTRACT_OWNER\fP
+is not specified, then SUID and SGID bits will only be restored
+if the default user and group IDs of newly-created objects on disk
+happen to match those specified in the archive entry.
+By default, only basic permissions are restored, and umask is obeyed.
+.TP
+\fBARCHIVE_EXTRACT_TIME\fP
+The timestamps (mtime, ctime, and atime) should be restored.
+By default, they are ignored.
+Note that restoring of atime is not currently supported.
+.TP
+\fBARCHIVE_EXTRACT_NO_OVERWRITE\fP
+Existing files on disk will not be overwritten.
+By default, existing regular files are truncated and overwritten;
+existing directories will have their permissions updated;
+other pre-existing objects are unlinked and recreated from scratch.
+.TP
+\fBARCHIVE_EXTRACT_UNLINK\fP
+Existing files on disk will be unlinked before any attempt to
+create them.
+In some cases, this can prove to be a significant performance improvement.
+By default, existing files are truncated and rewritten, but
+the file is not recreated.
+In particular, the default behavior does not break existing hard links.
+.TP
+\fBARCHIVE_EXTRACT_ACL\fP
+Attempt to restore ACLs.
+By default, extended ACLs are ignored.
+.TP
+\fBARCHIVE_EXTRACT_FFLAGS\fP
+Attempt to restore extended file flags.
+By default, file flags are ignored.
+.TP
+\fBARCHIVE_EXTRACT_XATTR\fP
+Attempt to restore POSIX.1e extended attributes.
+By default, they are ignored.
+.TP
+\fBARCHIVE_EXTRACT_SECURE_SYMLINKS\fP
+Refuse to extract any object whose final location would be altered
+by a symlink on disk.
+This is intended to help guard against a variety of mischief
+caused by archives that (deliberately or otherwise) extract
+files outside of the current directory.
+The default is not to perform this check.
+If
+\fBARCHIVE_EXTRACT_UNLINK\fP
+is specified together with this option, the library will
+remove any intermediate symlinks it finds and return an
+error only if such symlink could not be removed.
+.TP
+\fBARCHIVE_EXTRACT_SECURE_NODOTDOT\fP
+Refuse to extract a path that contains a
+\fI\& ..\fP
+element anywhere within it.
+The default is to not refuse such paths.
+Note that paths ending in
+\fI\& ..\fP
+always cause an error, regardless of this flag.
+.TP
+\fBARCHIVE_EXTRACT_SPARSE\fP
+Scan data for blocks of NUL bytes and try to recreate them with holes.
+This results in sparse files, independent of whether the archive format
+supports or uses them.
+.RE
+.TP
+\fB\%archive_write_disk_set_group_lookup\fP(),
+\fB\%archive_write_disk_set_user_lookup\fP()
+The
+Tn struct archive_entry
+objects contain both names and ids that can be used to identify users
+and groups.
+These names and ids describe the ownership of the file itself and
+also appear in ACL lists.
+By default, the library uses the ids and ignores the names, but
+this can be overridden by registering user and group lookup functions.
+To register, you must provide a lookup function which
+accepts both a name and id and returns a suitable id.
+You may also provide a
+Tn void *
+pointer to a private data structure and a cleanup function for
+that data.
+The cleanup function will be invoked when the
+Tn struct archive
+object is destroyed.
+.TP
+\fB\%archive_write_disk_set_standard_lookup\fP()
+This convenience function installs a standard set of user
+and group lookup functions.
+These functions use
+\fBgetpwnam\fP(3)
+and
+\fBgetgrnam\fP(3)
+to convert names to ids, defaulting to the ids if the names cannot
+be looked up.
+These functions also implement a simple memory cache to reduce
+the number of calls to
+\fBgetpwnam\fP(3)
+and
+\fBgetgrnam\fP(3).
+.TP
+\fB\%archive_write_header\fP()
+Build and write a header using the data in the provided
+Tn struct archive_entry
+structure.
+See
+\fBarchive_entry\fP(3)
+for information on creating and populating
+Tn struct archive_entry
+objects.
+.TP
+\fB\%archive_write_data\fP()
+Write data corresponding to the header just written.
+Returns number of bytes written or -1 on error.
+.TP
+\fB\%archive_write_finish_entry\fP()
+Close out the entry just written.
+Ordinarily, clients never need to call this, as it
+is called automatically by
+\fB\%archive_write_next_header\fP()
+and
+\fB\%archive_write_close\fP()
+as needed.
+.TP
+\fB\%archive_write_close\fP()
+Set any attributes that could not be set during the initial restore.
+For example, directory timestamps are not restored initially because
+restoring a subsequent file would alter that timestamp.
+Similarly, non-writable directories are initially created with
+write permissions (so that their contents can be restored).
+The
+\fB\%archive_write_disk_new\fP
+library maintains a list of all such deferred attributes and
+sets them when this function is invoked.
+.TP
+\fB\%archive_write_finish\fP()
+Invokes
+\fB\%archive_write_close\fP()
+if it was not invoked manually, then releases all resources.
+.RE
+More information about the
+\fIstruct\fP archive
+object and the overall design of the library can be found in the
+\fBlibarchive\fP(3)
+overview.
+Many of these functions are also documented under
+\fBarchive_write\fP(3).
+.SH RETURN VALUES
+.ad l
+Most functions return
+\fBARCHIVE_OK\fP
+(zero) on success, or one of several non-zero
+error codes for errors.
+Specific error codes include:
+\fBARCHIVE_RETRY\fP
+for operations that might succeed if retried,
+\fBARCHIVE_WARN\fP
+for unusual conditions that do not prevent further operations, and
+\fBARCHIVE_FATAL\fP
+for serious errors that make remaining operations impossible.
+The
+\fB\%archive_errno\fP()
+and
+\fB\%archive_error_string\fP()
+functions can be used to retrieve an appropriate error code and a
+textual error message.
+.PP
+\fB\%archive_write_disk_new\fP()
+returns a pointer to a newly-allocated
+Tn struct archive
+object.
+.PP
+\fB\%archive_write_data\fP()
+returns a count of the number of bytes actually written.
+On error, -1 is returned and the
+\fB\%archive_errno\fP()
+and
+\fB\%archive_error_string\fP()
+functions will return appropriate values.

+.ad l
+The
+\fB\%libarchive\fP
+library first appeared in

+The
+\fB\%archive_write_disk\fP
+interface was added to
+\fB\%libarchive\fP 2.0
+and first appeared in

+.SH AUTHORS
+.ad l
+-nosplit
+The
+\fB\%libarchive\fP
+library was written by
+Tim Kientzle \%<kientzle@acm.org.>
+.SH BUGS
+.ad l
+Directories are actually extracted in two distinct phases.
+Directories are created during
+\fB\%archive_write_header\fP(),
+but final permissions are not set until
+\fB\%archive_write_close\fP().
+This separation is necessary to correctly handle borderline
+cases such as a non-writable directory containing
+files, but can cause unexpected results.
+In particular, directory permissions are not fully
+restored until the archive is closed.
+If you use
+\fBchdir\fP(2)
+to change the current directory between calls to
+\fB\%archive_read_extract\fP()
+or before calling
+\fB\%archive_read_close\fP(),
+you may confuse the permission-setting logic with
+the result that directory permissions are restored
+incorrectly.
+.PP
+The library attempts to create objects with filenames longer than
+\fBPATH_MAX\fP
+by creating prefixes of the full path and changing the current directory.
+Currently, this logic is limited in scope; the fixup pass does
+not work correctly for such objects and the symlink security check
+option disables the support for very long pathnames.
+.PP
+Restoring the path
+\fIaa/../bb\fP
+does create each intermediate directory.
+In particular, the directory
+\fIaa\fP
+is created as well as the final object
+\fIbb\fP.
+In theory, this can be exploited to create an entire directory heirarchy
+with a single request.
+Of course, this does not work if the
+\fBARCHIVE_EXTRACT_NODOTDOT\fP
+option is specified.
+.PP
+Implicit directories are always created obeying the current umask.
+Explicit objects are created obeying the current umask unless
+\fBARCHIVE_EXTRACT_PERM\fP
+is specified, in which case they current umask is ignored.
+.PP
+SGID and SUID bits are restored only if the correct user and
+group could be set.
+If
+\fBARCHIVE_EXTRACT_OWNER\fP
+is not specified, then no attempt is made to set the ownership.
+In this case, SGID and SUID bits are restored only if the
+user and group of the final object happen to match those specified
+in the entry.
+.PP
+The
+``standard''
+user-id and group-id lookup functions are not the defaults because
+\fBgetgrnam\fP(3)
+and
+\fBgetpwnam\fP(3)
+are sometimes too large for particular applications.
+The current design allows the application author to use a more
+compact implementation when appropriate.
+.PP
+There should be a corresponding
+\fB\%archive_read_disk\fP
+interface that walks a directory heirarchy and returns archive
+entry objects.

+.SH HISTORY
+.ad l
+The original
+\fB\%cpio\fP
+and
+\fB\%find\fP
+utilities were written by Dick Haight
+while working in AT&T's Unix Support Group.
+They first appeared in 1977 in PWB/UNIX 1.0, the
+``Programmer's Work Bench''
+system developed for use within AT&T.
+They were first released outside of AT&T as part of System III Unix in 1981.
+As a result,
+\fB\%cpio\fP
+actually predates
+\fB\%tar\fP,
+even though it was not well-known outside of AT&T until some time later.
+.PP
+This is a complete re-implementation based on the
+\fBlibarchive\fP(3)
+library.
+.SH BUGS
+.ad l
+The cpio archive format has several basic limitations:
+It does not store user and group names, only numbers.
+As a result, it cannot be reliably used to transfer
+files between systems with dissimilar user and group numbering.
+Older cpio formats limit the user and group numbers to
+16 or 18 bits, which is insufficient for modern systems.
+The cpio archive formats cannot support files over 4 gigabytes,
+except for the
+``odc''
+variant, which can support files up to 8 gigabytes.

+.SH DESCRIPTION
+.ad l
+\fB\%tar\fP
+creates and manipulates streaming archive files.
+This implementation can extract from tar, pax, cpio, zip, jar, ar,
+and ISO 9660 cdrom images and can create tar, pax, cpio, ar,
+and shar archives.
+.PP
+The first synopsis form shows a
+``bundled''
+option word.
+This usage is provided for compatibility with historical implementations.
+See COMPATIBILITY below for details.
+.PP
+The other synopsis forms show the preferred usage.
+The first option to
+\fB\%tar\fP
+is a mode indicator from the following list:
+.RS 5
+.TP
+\fB\-c\fP
+Create a new archive containing the specified items.
+.TP
+\fB\-r\fP
+Like
+\fB\-c\fP,
+but new entries are appended to the archive.
+Note that this only works on uncompressed archives stored in regular files.
+The
+\fB\-f\fP
+option is required.
+.TP
+\fB\-t\fP
+List archive contents to stdout.
+.TP
+\fB\-u\fP
+Like
+\fB\-r\fP,
+but new entries are added only if they have a modification date
+newer than the corresponding entry in the archive.
+Note that this only works on uncompressed archives stored in regular files.
+The
+\fB\-f\fP
+option is required.
+.TP
+\fB\-x\fP
+Extract to disk from the archive.
+If a file with the same name appears more than once in the archive,
+each copy will be extracted, with later copies overwriting (replacing)
+earlier copies.
+.RE
+.PP
+In
+\fB\-c\fP,
+\fB\-r\fP,
+or
+\fB\-u\fP
+mode, each specified file or directory is added to the
+archive in the order specified on the command line.
+By default, the contents of each directory are also archived.
+.PP
+In extract or list mode, the entire command line
+is read and parsed before the archive is opened.
+The pathnames or patterns on the command line indicate
+which items in the archive should be processed.
+Patterns are shell-style globbing patterns as
+documented in
+\fBtcsh\fP(1).
+.SH OPTIONS
+.ad l
+Unless specifically stated otherwise, options are applicable in
+all operating modes.
+.RS 5
+.TP
+\fB@\fP \fIarchive\fP
+(c and r mode only)
+The specified archive is opened and the entries
+in it will be appended to the current archive.
+As a simple example,
+.RS 4
+\fB\%tar\fP \fB\-c\fP \fB\-f\fP \fI-\fP \fInewfile\fP \fB@\fP \fIoriginal.tar\fP
+.RE
+writes a new archive to standard output containing a file
+\fInewfile\fP
+and all of the entries from
+\fIoriginal.tar\fP.
+In contrast,
+.RS 4
+\fB\%tar\fP \fB\-c\fP \fB\-f\fP \fI-\fP \fInewfile\fP \fIoriginal.tar\fP
+.RE
+creates a new archive with only two entries.
+Similarly,
+.RS 4
+\fB\%tar\fP \fB\-czf\fP \fI-\fP \fB\--format\fP \fBpax\fP \fB@\fP \fI-\fP
+.RE
+reads an archive from standard input (whose format will be determined
+automatically) and converts it into a gzip-compressed
+pax-format archive on stdout.
+In this way,
+\fB\%tar\fP
+can be used to convert archives from one format to another.
+.TP
+\fB\-b\fP \fIblocksize\fP
+Specify the block size, in 512-byte records, for tape drive I/O.
+As a rule, this argument is only needed when reading from or writing
+to tape drives, and usually not even then as the default block size of
+20 records (10240 bytes) is very common.
+.TP
+\fB\-C\fP \fIdirectory\fP
+In c and r mode, this changes the directory before adding
+the following files.
+In x mode, change directories after opening the archive
+but before extracting entries from the archive.
+.TP
+\fB\--check-links\fP
+(c and r modes only)
+Issue a warning message unless all links to each file are archived.
+.TP
+\fB\--chroot\fP
+(x mode only)
+\fB\%chroot\fP()
+to the current directory after processing any
+\fB\-C\fP
+options and before extracting any files.
+.TP
+\fB\--exclude\fP \fIpattern\fP
+Do not process files or directories that match the
+specified pattern.
+Note that exclusions take precedence over patterns or filenames
+specified on the command line.
+.TP
+\fB\--format\fP \fIformat\fP
+(c, r, u mode only)
+Use the specified format for the created archive.
+Supported formats include
+``cpio'',
+``pax'',
+``shar'',
+and
+``ustar''.
+Other formats may also be supported; see
+\fBlibarchive-formats\fP(5)
+for more information about currently-supported formats.
+In r and u modes, when extending an existing archive, the format specified
+here must be compatible with the format of the existing archive on disk.
+.TP
+\fB\-f\fP \fIfile\fP
+Read the archive from or write the archive to the specified file.
+The filename can be
+\fI-\fP
+for standard input or standard output.
+If not specified, the default tape device will be used.
+(On
+FreeBSD,
+the default tape device is
+\fI/dev/sa0\fP.)
+.TP
+\fB\-H\fP
+(c and r mode only)
+Symbolic links named on the command line will be followed; the
+target of the link will be archived, not the link itself.
+.TP
+\fB\-h\fP
+(c and r mode only)
+Synonym for
+\fB\-L\fP.
+.TP
+\fB\-I\fP
+Synonym for
+\fB\-T\fP.
+.TP
+\fB\--include\fP \fIpattern\fP
+Process only files or directories that match the specified pattern.
+Note that exclusions specified with
+\fB\--exclude\fP
+take precedence over inclusions.
+If no inclusions are explicitly specified, all entries are processed by
+default.
+The
+\fB\--include\fP
+option is especially useful when filtering archives.
+For example, the command
+.RS 4
+\fB\%tar\fP \fB\-c\fP \fB\-f\fP \fInew.tar\fP \fB\--include='*foo*'\fP \fB@\fP \fIold.tgz\fP
+.RE
+creates a new archive
+\fInew.tar\fP
+containing only the entries from
+\fIold.tgz\fP
+containing the string
+Sq foo.
+.TP
+\fB\-j\fP
+(c mode only)
+Compress the resulting archive with
+\fBbzip2\fP(1).
+In extract or list modes, this option is ignored.
+Note that, unlike other
+\fB\%tar\fP
+implementations, this implementation recognizes bzip2 compression
+automatically when reading archives.
+.TP
+\fB\-k\fP
+(x mode only)
+Do not overwrite existing files.
+In particular, if a file appears more than once in an archive,
+later copies will not overwrite earlier copies.
+.TP
+\fB\--keep-newer-files\fP
+(x mode only)
+Do not overwrite existing files that are newer than the
+versions appearing in the archive being extracted.
+.TP
+\fB\-L\fP
+(c and r mode only)
+All symbolic links will be followed.
+Normally, symbolic links are archived as such.
+With this option, the target of the link will be archived instead.
+.TP
+\fB\-l\fP
+This is a synonym for the
+\fB\--check-links\fP
+option.
+.TP
+\fB\-m\fP
+(x mode only)
+Do not extract modification time.
+By default, the modification time is set to the time stored in the archive.
+.TP
+\fB\-n\fP
+(c, r, u modes only)
+Do not recursively archive the contents of directories.
+.TP
+\fB\--newer\fP \fIdate\fP
+(c, r, u modes only)
+Only include files and directories newer than the specified date.
+This compares ctime entries.
+.TP
+\fB\--newer-mtime\fP \fIdate\fP
+(c, r, u modes only)
+Like
+\fB\--newer\fP,
+except it compares mtime entries instead of ctime entries.
+.TP
+\fB\--newer-than\fP \fIfile\fP
+(c, r, u modes only)
+Only include files and directories newer than the specified file.
+This compares ctime entries.
+.TP
+\fB\--newer-mtime-than\fP \fIfile\fP
+(c, r, u modes only)
+Like
+\fB\--newer-than\fP,
+except it compares mtime entries instead of ctime entries.
+.TP
+\fB\--nodump\fP
+(c and r modes only)
+Honor the nodump file flag by skipping this file.
+.TP
+\fB\--null\fP
+(use with
+\fB\-I\fP,
+\fB\-T\fP,
+or
+\fB\-X\fP)
+Filenames or patterns are separated by null characters,
+not by newlines.
+This is often used to read filenames output by the
+\fB\-print0\fP
+option to
+\fBfind\fP(1).
+.TP
+\fB\--numeric-owner\fP
+(x mode only)
+Ignore symbolic user and group names when restoring archives to disk,
+only numeric uid and gid values will be obeyed.
+.TP
+\fB\-O\fP
+(x, t modes only)
+In extract (-x) mode, files will be written to standard out rather than
+being extracted to disk.
+In list (-t) mode, the file listing will be written to stderr rather than
+the usual stdout.
+.TP
+\fB\-o\fP
+(x mode)
+Use the user and group of the user running the program rather
+than those specified in the archive.
+Note that this has no significance unless
+\fB\-p\fP
+is specified, and the program is being run by the root user.
+In this case, the file modes and flags from
+the archive will be restored, but ACLs or owner information in
+the archive will be discarded.
+.TP
+\fB\-o\fP
+(c, r, u mode)
+A synonym for
+\fB\--format\fP \fIustar\fP
+.TP
+\fB\--one-file-system\fP
+(c, r, and u modes)
+Do not cross mount points.
+.TP
+\fB\--options\fP \fIoptions\fP
+Select optional behaviors for particular modules.
+The argument is a text string containing comma-separated
+keywords and values.
+These are passed to the modules that handle particular
+formats to control how those formats will behave.
+Each option has one of the following forms:
+.RS 5
+.TP
+\fIkey=value\fP
+The key will be set to the specified value in every module that supports it.
+Modules that do not support this key will ignore it.
+.TP
+\fIkey\fP
+The key will be enabled in every module that supports it.
+This is equivalent to
+\fIkey\fP \fB=1\fP.
+.TP
+\fI!key\fP
+The key will be disabled in every module that supports it.
+.TP
+\fImodule:key=value\fP, \fImodule:key\fP, \fImodule:!key\fP
+As above, but the corresponding key and value will be provided
+only to modules whose name matches
+\fImodule\fP.
+.RE
+The currently supported modules and keys are:
+.RS 5
+.TP
+\fBiso9660:joliet\fP
+Support Joliet extensions.
+This is enabled by default, use
+\fB!joliet\fP
+or
+\fBiso9660:!joliet\fP
+to disable.
+.TP
+\fBiso9660:rockridge\fP
+Support Rock Ridge extensions.
+This is enabled by default, use
+\fB!rockridge\fP
+or
+\fBiso9660:!rockridge\fP
+to disable.
+.TP
+\fBgzip:compression-level\fP
+A decimal integer from 0 to 9 specifying the gzip compression level.
+.TP
+\fBxz:compression-level\fP
+A decimal integer from 0 to 9 specifying the xz compression level.
+.TP
+\fBmtree:\fP \fIkeyword\fP
+The mtree writer module allows you to specify which mtree keywords
+will be included in the output.
+Supported keywords include:
+\fBcksum\fP, \fBdevice\fP, \fBflags\fP, \fBgid\fP, \fBgname\fP, \fBindent\fP,
+\fBlink\fP, \fBmd5\fP, \fBmode\fP, \fBnlink\fP, \fBrmd160\fP, \fBsha1\fP, \fBsha256\fP,
+\fBsha384\fP, \fBsha512\fP, \fBsize\fP, \fBtime\fP, \fBuid\fP, \fBuname\fP.
+The default is equivalent to:
+``device, flags, gid, gname, link, mode, nlink, size, time, type, uid, uname''.
+.TP
+\fBmtree:all\fP
+Enables all of the above keywords.
+You can also use
+\fBmtree:!all\fP
+to disable all keywords.
+.TP
+\fBmtree:use-set\fP
+Enable generation of
+\fB/set\fP
+lines in the output.
+.TP
+\fBmtree:indent\fP
+Produce human-readable output by indenting options and splitting lines
+to fit into 80 columns.
+.TP
+\fBzip:compression\fP=\fItype\fP
+Use
+\fItype\fP
+as compression method.
+Supported values are store (uncompressed) and deflate (gzip algorithm).
+.RE
+If a provided option is not supported by any module, that
+is a fatal error.
+.TP
+\fB\-P\fP
+Preserve pathnames.
+By default, absolute pathnames (those that begin with a /
+character) have the leading slash removed both when creating archives
+and extracting from them.
+Also,
+\fB\%tar\fP
+will refuse to extract archive entries whose pathnames contain
+\fI\& ..\fP
+or whose target directory would be altered by a symlink.
+This option suppresses these behaviors.
+.TP
+\fB\-p\fP
+(x mode only)
+Preserve file permissions.
+Attempt to restore the full permissions, including owner, file modes, file
+flags and ACLs, if available, for each item extracted from the archive.
+By default, newly-created files are owned by the user running
+\fB\%tar\fP,
+the file mode is restored for newly-created regular files, and
+all other types of entries receive default permissions.
+If
+\fB\%tar\fP
+is being run by root, the default is to restore the owner unless the
+\fB\-o\fP
+option is also specified.
+.TP
+\fB\-q\fP (\fB\--fast-read\fP)
+(x and t mode only)
+Extract or list only the first archive entry that matches each pattern
+or filename operand.
+Exit as soon as each specified pattern or filename has been matched.
+By default, the archive is always read to the very end, since
+there can be multiple entries with the same name and, by convention,
+later entries overwrite earlier entries.
+This option is provided as a performance optimization.
+.TP
+\fB\-S\fP
+(x mode only)
+Extract files as sparse files.
+For every block on disk, check first if it contains only NULL bytes and seek
+over it otherwise.
+This works similiar to the conv=sparse option of dd.
+.TP
+\fB\--strip-components\fP \fIcount\fP
+(x mode only)
+Remove the specified number of leading path elements.
+Pathnames with fewer elements will be silently skipped.
+Note that the pathname is edited after checking inclusion/exclusion patterns
+but before security checks.
+.TP
+\fB\-s\fP \fIpattern\fP
+Modify file or archive member names according to
+\fIpattern\fP.
+The pattern has the format
+\fI/old/new/\fP [gps]
+where
+\fIold\fP
+is a basic regular expression,
+\fInew\fP
+is the replacement string of the matched part,
+and the optional trailing letters modify
+how the replacement is handled.
+If
+\fIold\fP
+is not matched, the pattern is skipped.
+Within
+\fInew\fP,
+~ is substituted with the match, \1 to \9 with the content of
+the corresponding captured group.
+The optional trailing g specifies that matching should continue
+after the matched part and stopped on the first unmatched pattern.
+The optional trailing s specifies that the pattern applies to the value
+of symbolic links.
+The optional trailing p specifies that after a successful substitution
+the original path name and the new path name should be printed to
+standard error.
+.TP
+\fB\-T\fP \fIfilename\fP
+In x or t mode,
+\fB\%tar\fP
+will read the list of names to be extracted from
+\fIfilename\fP.
+In c mode,
+\fB\%tar\fP
+will read names to be archived from
+\fIfilename\fP.
+The special name
+``-C''
+on a line by itself will cause the current directory to be changed to
+the directory specified on the following line.
+Names are terminated by newlines unless
+\fB\--null\fP
+is specified.
+Note that
+\fB\--null\fP
+also disables the special handling of lines containing
+``-C''.
+.TP
+\fB\-U\fP
+(x mode only)
+Unlink files before creating them.
+Without this option,
+\fB\%tar\fP
+overwrites existing files, which preserves existing hardlinks.
+With this option, existing hardlinks will be broken, as will any
+symlink that would affect the location of an extracted file.
+.TP
+\fB\--use-compress-program\fP \fIprogram\fP
+Pipe the input (in x or t mode) or the output (in c mode) through
+\fIprogram\fP
+instead of using the builtin compression support.
+.TP
+\fB\-v\fP
+Produce verbose output.
+In create and extract modes,
+\fB\%tar\fP
+will list each file name as it is read from or written to

+.SH SECURITY
+.ad l
+Certain security issues are common to many archiving programs, including
+\fB\%tar\fP.
+In particular, carefully-crafted archives can request that
+\fB\%tar\fP
+extract files to locations outside of the target directory.
+This can potentially be used to cause unwitting users to overwrite
+files they did not intend to overwrite.
+If the archive is being extracted by the superuser, any file
+on the system can potentially be overwritten.
+There are three ways this can happen.
+Although
+\fB\%tar\fP
+has mechanisms to protect against each one,
+savvy users should be aware of the implications:
+.RS 5
+.IP \(bu
+Archive entries can have absolute pathnames.
+By default,
+\fB\%tar\fP
+removes the leading
+\fI/\fP
+character from filenames before restoring them to guard against this problem.
+.IP \(bu
+Archive entries can have pathnames that include
+\fI\& ..\fP
+components.
+By default,
+\fB\%tar\fP
+will not extract files containing
+\fI\& ..\fP
+components in their pathname.
+.IP \(bu
+Archive entries can exploit symbolic links to restore
+files to other directories.
+An archive can restore a symbolic link to another directory,
+then use that link to restore a file into that directory.
+To guard against this,
+\fB\%tar\fP
+checks each extracted path for symlinks.

+A
+\fB\%tar\fP
+command appeared in Seventh Edition Unix, which was released in January, 1979.
+There have been numerous other implementations,
+many of which extended the file format.
+John Gilmore's
+\fB\%pdtar\fP
+public-domain implementation (circa November, 1987)
+was quite influential, and formed the basis of GNU tar.
+GNU tar was included as the standard system tar
+in
+FreeBSD
+beginning with
+FreeBSD 1.0.
+.PP
+This is a complete re-implementation based on the
+\fBlibarchive\fP(3)
+library.
+.SH BUGS
+.ad l
+This program follows
+ISO/IEC 9945-1:1996 (``POSIX.1'')
+for the definition of the
+\fB\-l\fP
+option.
+Note that GNU tar prior to version 1.15 treated
+\fB\-l\fP
+as a synonym for the
+\fB\--one-file-system\fP
+option.
+.PP
+The
+\fB\-C\fP \fIdir\fP
+option may differ from historic implementations.
+.PP
+All archive output is written in correctly-sized blocks, even
+if the output is being compressed.
+Whether or not the last output block is padded to a full
+block size varies depending on the format and the
+output device.
+For tar and cpio formats, the last block of output is padded
+to a full block size if the output is being
+written to standard output or to a character or block device such as
+a tape drive.
+If the output is being written to a regular file, the last block
+will not be padded.
+Many compressors, including
+\fBgzip\fP(1)
+and
+\fBbzip2\fP(1),
+complain about the null padding when decompressing an archive created by
+\fB\%tar\fP,
+although they still extract it correctly.

+The compression and decompression is implemented internally, so

+The default should be to read and write archives to the standard I/O paths,
+but tradition (and POSIX) dictates otherwise.
+.PP
+The
+\fBr\fP

+There needs to be better support for file selection on both create

+.SH NAME
+.ad l
+\fB\%cpio\fP
+\- format of cpio archive files
+.SH DESCRIPTION
+.ad l
+The
+\fB\%cpio\fP
+archive format collects any number of files, directories, and other
+file system objects (symbolic links, device nodes, etc.) into a single
+stream of bytes.
+.SS General Format
+Each file system object in a
+\fB\%cpio\fP
+archive comprises a header record with basic numeric metadata
+followed by the full pathname of the entry and the file data.
+The header record stores a series of integer values that generally
+follow the fields in
+\fIstruct\fP stat.
+(See
+\fBstat\fP(2)
+for details.)
+The variants differ primarily in how they store those integers
+(binary, octal, or hexadecimal).
+The header is followed by the pathname of the
+entry (the length of the pathname is stored in the header)
+and any file data.
+The end of the archive is indicated by a special record with
+the pathname
+``TRAILER!!!''.
+.SS PWB format
+XXX Any documentation of the original PWB/UNIX 1.0 format? XXX
+.SS Old Binary Format
+The old binary
+\fB\%cpio\fP
+format stores numbers as 2-byte and 4-byte binary values.
+Each entry begins with a header in the following format:
+.RS 4
+.nf
+struct header_old_cpio {
+        unsigned short   c_magic;
+        unsigned short   c_dev;
+        unsigned short   c_ino;

+        unsigned short   c_rdev;
+       unsigned short   c_mtime[2];
+        unsigned short   c_namesize;
+       unsigned short   c_filesize[2];
+};
+.RE
+.PP
+The
+\fIunsigned\fP short
+fields here are 16-bit integer values; the
+\fIunsigned\fP int
+fields are 32-bit integer values.
+The fields are as follows
+.RS 5
+.TP
+\fImagic\fP
+The integer value octal 070707.
+This value can be used to determine whether this archive is
+written with little-endian or big-endian integers.
+.TP
+\fIdev\fP, \fIino\fP
+The device and inode numbers from the disk.
+These are used by programs that read
+\fB\%cpio\fP
+archives to determine when two entries refer to the same file.
+Programs that synthesize
+\fB\%cpio\fP
+archives should be careful to set these to distinct values for each entry.
+.TP
+\fImode\fP
+The mode specifies both the regular permissions and the file type.
+It consists of several bit fields as follows:
+.RS 5
+.TP
+0170000
+This masks the file type bits.
+.TP
+0140000
+File type value for sockets.
+.TP
+0120000
+File type value for symbolic links.
+For symbolic links, the link body is stored as file data.
+.TP
+0100000
+File type value for regular files.
+.TP
+0060000
+File type value for block special devices.
+.TP
+0040000
+File type value for directories.
+.TP
+0020000
+File type value for character special devices.
+.TP
+0010000
+File type value for named pipes or FIFOs.
+.TP
+0004000
+SUID bit.
+.TP
+0002000
+SGID bit.
+.TP
+0001000
+Sticky bit.
+On some systems, this modifies the behavior of executables and/or directories.
+.TP
+0000777
+The lower 9 bits specify read/write/execute permissions
+for world, group, and user following standard POSIX conventions.
+.RE
+.TP
+\fIuid\fP, \fIgid\fP
+The numeric user id and group id of the owner.
+.TP
+\fInlink\fP
+The number of links to this file.
+Directories always have a value of at least two here.
+Note that hardlinked files include file data with every copy in the archive.
+.TP
+\fIrdev\fP
+For block special and character special entries,
+this field contains the associated device number.
+For all other entry types, it should be set to zero by writers
+and ignored by readers.
+.TP
+\fImtime\fP
+Modification time of the file, indicated as the number
+of seconds since the start of the epoch,
+00:00:00 UTC January 1, 1970.
+The four-byte integer is stored with the most-significant 16 bits first
+followed by the least-significant 16 bits.
+Each of the two 16 bit values are stored in machine-native byte order.
+.TP
+\fInamesize\fP
+The number of bytes in the pathname that follows the header.
+This count includes the trailing NUL byte.
+.TP
+\fIfilesize\fP
+The size of the file.
+Note that this archive format is limited to
+four gigabyte file sizes.
+See
+\fImtime\fP
+above for a description of the storage of four-byte integers.
+.RE
+.PP
+The pathname immediately follows the fixed header.
+If the
+\fBnamesize\fP
+is odd, an additional NUL byte is added after the pathname.
+The file data is then appended, padded with NUL
+bytes to an even length.
+.PP
+Hardlinked files are not given special treatment;
+the full file contents are included with each copy of the
+file.
+.SS Portable ASCII Format
+Version 2 of the Single UNIX Specification (``SUSv2'')
+standardized an ASCII variant that is portable across all
+platforms.
+It is commonly known as the
+``old character''
+format or as the
+``odc''
+format.
+It stores the same numeric fields as the old binary format, but
+represents them as 6-character or 11-character octal values.

+.RE
+.PP
+The fields are identical to those in the old binary format.
+The name and file body follow the fixed header.
+Unlike the old binary format, there is no additional padding
+after the pathname or file contents.
+If the files being archived are themselves entirely ASCII, then
+the resulting archive will be entirely ASCII, except for the
+NUL byte that terminates the name field.
+.SS New ASCII Format
+The "new" ASCII format uses 8-byte hexadecimal fields for
+all numbers and separates device numbers into separate fields
+for major and minor numbers.

+\fB\%libarchive-formats\fP
+\- archive formats supported by the libarchive library
+.SH DESCRIPTION
+.ad l
+The
+\fBlibarchive\fP(3)
+library reads and writes a variety of streaming archive formats.
+Generally speaking, all of these archive formats consist of a series of
+``entries''.
+Each entry stores a single file system object, such as a file, directory,
+or symbolic link.
+.PP
+The following provides a brief description of each format supported
+by libarchive, with some information about recognized extensions or
+limitations of the current library support.
+Note that just because a format is supported by libarchive does not
+imply that a program that uses libarchive will support that format.
+Applications that use libarchive specify which formats they wish
+to support, though many programs do use libarchive convenience
+functions to enable all supported formats.
+.SS Tar Formats
+The
+\fBlibarchive\fP(3)
+library can read most tar archives.
+However, it only writes POSIX-standard
+``ustar''
+and
+``pax interchange''
+formats.
+.PP
+All tar formats store each entry in one or more 512-byte records.
+The first record is used for file metadata, including filename,
+timestamp, and mode information, and the file data is stored in
+subsequent records.
+Later variants have extended this by either appropriating undefined
+areas of the header record, extending the header to multiple records,
+or by storing special entries that modify the interpretation of
+subsequent entries.
+.PP
+.RS 5
+.TP
+\fBgnutar\fP
+The
+\fBlibarchive\fP(3)
+library can read GNU-format tar archives.
+It currently supports the most popular GNU extensions, including
+modern long filename and linkname support, as well as atime and ctime data.
+The libarchive library does not support multi-volume
+archives, nor the old GNU long filename format.
+It can read GNU sparse file entries, including the new POSIX-based
+formats, but cannot write GNU sparse file entries.
+.TP
+\fBpax\fP
+The
+\fBlibarchive\fP(3)
+library can read and write POSIX-compliant pax interchange format
+archives.
+Pax interchange format archives are an extension of the older ustar
+format that adds a separate entry with additional attributes stored
+as key/value pairs immediately before each regular entry.
+The presence of these additional entries is the only difference between
+pax interchange format and the older ustar format.
+The extended attributes are of unlimited length and are stored
+as UTF-8 Unicode strings.
+Keywords defined in the standard are in all lowercase; vendors are allowed
+to define custom keys by preceding them with the vendor name in all uppercase.
+When writing pax archives, libarchive uses many of the SCHILY keys
+defined by Joerg Schilling's
+``star''
+archiver and a few LIBARCHIVE keys.
+The libarchive library can read most of the SCHILY keys
+and most of the GNU keys introduced by GNU tar.
+It silently ignores any keywords that it does not understand.
+.TP
+\fBrestricted\fP pax
+The libarchive library can also write pax archives in which it
+attempts to suppress the extended attributes entry whenever
+possible.
+The result will be identical to a ustar archive unless the
+extended attributes entry is required to store a long file
+name, long linkname, extended ACL, file flags, or if any of the standard
+ustar data (user name, group name, UID, GID, etc) cannot be fully
+represented in the ustar header.
+In all cases, the result can be dearchived by any program that
+can read POSIX-compliant pax interchange format archives.
+Programs that correctly read ustar format (see below) will also be
+able to read this format; any extended attributes will be extracted as
+separate files stored in
+\fIPaxHeader\fP
+directories.
+.TP
+\fBustar\fP
+The libarchive library can both read and write this format.
+This format has the following limitations:
+.RS 5
+.IP \(bu
+Device major and minor numbers are limited to 21 bits.
+Nodes with larger numbers will not be added to the archive.
+.IP \(bu
+Path names in the archive are limited to 255 bytes.
+(Shorter if there is no / character in exactly the right place.)
+.IP \(bu
+Symbolic links and hard links are stored in the archive with
+the name of the referenced file.
+This name is limited to 100 bytes.
+.IP \(bu
+Extended attributes, file flags, and other extended
+security information cannot be stored.
+.IP \(bu
+Archive entries are limited to 8 gigabytes in size.
+.RE
+Note that the pax interchange format has none of these restrictions.
+.RE
+.PP
+The libarchive library also reads a variety of commonly-used extensions to
+the basic tar format.
+These extensions are recognized automatically whenever they appear.
+.RS 5
+.TP
+Numeric extensions.
+The POSIX standards require fixed-length numeric fields to be written with
+some character position reserved for terminators.
+Libarchive allows these fields to be written without terminator characters.
+This extends the allowable range; in particular, ustar archives with this
+extension can support entries up to 64 gigabytes in size.
+Libarchive also recognizes base-256 values in most numeric fields.
+This essentially removes all limitations on file size, modification time,
+and device numbers.
+.TP
+Solaris extensions
+Libarchive recognizes ACL and extended attribute records written
+by Solaris tar.
+Currently, libarchive only has support for old-style ACLs; the
+newer NFSv4 ACLs are recognized but discarded.
+.RE
+.PP
+The first tar program appeared in Seventh Edition Unix in 1979.
+The first official standard for the tar file format was the
+``ustar''
+(Unix Standard Tar) format defined by POSIX in 1988.
+POSIX.1-2001 extended the ustar format to create the
+``pax interchange''
+format.
+.SS Cpio Formats
+The libarchive library can read a number of common cpio variants and can write
+``odc''
+and
+``newc''
+format archives.
+A cpio archive stores each entry as a fixed-size header followed
+by a variable-length filename and variable-length data.
+Unlike the tar format, the cpio format does only minimal padding
+of the header or file data.
+There are several cpio variants, which differ primarily in
+how they store the initial header: some store the values as
+octal or hexadecimal numbers in ASCII, others as binary values of
+varying byte order and length.
+.RS 5
+.TP
+\fBbinary\fP
+The libarchive library transparently reads both big-endian and little-endian
+variants of the original binary cpio format.
+This format used 32-bit binary values for file size and mtime,
+and 16-bit binary values for the other fields.
+.TP
+\fBodc\fP
+The libarchive library can both read and write this
+POSIX-standard format, which is officially known as the
+``cpio interchange format''
+or the
+``octet-oriented cpio archive format''
+and sometimes unofficially referred to as the
+``old character format''.
+This format stores the header contents as octal values in ASCII.
+It is standard, portable, and immune from byte-order confusion.
+File sizes and mtime are limited to 33 bits (8GB file size),
+other fields are limited to 18 bits.
+.TP
+\fBSVR4\fP
+The libarchive library can read both CRC and non-CRC variants of
+this format.
+The SVR4 format uses eight-digit hexadecimal values for
+all header fields.
+This limits file size to 4GB, and also limits the mtime and
+other fields to 32 bits.
+The SVR4 format can optionally include a CRC of the file
+contents, although libarchive does not currently verify this CRC.
+.RE
+.PP
+Cpio first appeared in PWB/UNIX 1.0, which was released within
+AT&T in 1977.
+PWB/UNIX 1.0 formed the basis of System III Unix, released outside
+of AT&T in 1981.
+This makes cpio older than tar, although cpio was not included
+in Version 7 AT&T Unix.
+As a result, the tar command became much better known in universities
+and research groups that used Version 7.
+The combination of the
+\fB\%find\fP
+and
+\fB\%cpio\fP
+utilities provided very precise control over file selection.
+Unfortunately, the format has many limitations that make it unsuitable
+for widespread use.
+Only the POSIX format permits files over 4GB, and its 18-bit
+limit for most other fields makes it unsuitable for modern systems.
+In addition, cpio formats only store numeric UID/GID values (not
+usernames and group names), which can make it very difficult to correctly
+transfer archives across systems with dissimilar user numbering.
+.SS Shar Formats
+A
+``shell archive''
+is a shell script that, when executed on a POSIX-compliant
+system, will recreate a collection of file system objects.
+The libarchive library can write two different kinds of shar archives:
+.RS 5
+.TP
+\fBshar\fP
+The traditional shar format uses a limited set of POSIX
+commands, including
+\fBecho\fP(1),
+\fBmkdir\fP(1),
+and
+\fBsed\fP(1).
+It is suitable for portably archiving small collections of plain text files.
+However, it is not generally well-suited for large archives
+(many implementations of
+\fBsh\fP(1)
+have limits on the size of a script) nor should it be used with non-text files.
+.TP
+\fBshardump\fP
+This format is similar to shar but encodes files using
+\fBuuencode\fP(1)
+so that the result will be a plain text file regardless of the file contents.
+It also includes additional shell commands that attempt to reproduce as
+many file attributes as possible, including owner, mode, and flags.
+The additional commands used to restore file attributes make
+shardump archives less portable than plain shar archives.
+.RE
+.SS ISO9660 format
+Libarchive can read and extract from files containing ISO9660-compliant
+CDROM images.
+In many cases, this can remove the need to burn a physical CDROM
+just in order to read the files contained in an ISO9660 image.
+It also avoids security and complexity issues that come with
+virtual mounts and loopback devices.
+Libarchive supports the most common Rockridge extensions and has partial
+support for Joliet extensions.
+If both extensions are present, the Joliet extensions will be
+used and the Rockridge extensions will be ignored.
+In particular, this can create problems with hardlinks and symlinks,
+which are supported by Rockridge but not by Joliet.
+.SS Zip format
+Libarchive can read and write zip format archives that have
+uncompressed entries and entries compressed with the
+``deflate''
+algorithm.
+Older zip compression algorithms are not supported.
+It can extract jar archives, archives that use Zip64 extensions and many
+self-extracting zip archives.
+Libarchive reads Zip archives as they are being streamed,
+which allows it to read archives of arbitrary size.
+It currently does not use the central directory; this
+limits libarchive's ability to support some self-extracting
+archives and ones that have been modified in certain ways.
+.SS Archive (library) file format
+The Unix archive format (commonly created by the
+\fBar\fP(1)
+archiver) is a general-purpose format which is
+used almost exclusively for object files to be
+read by the link editor
+\fBld\fP(1).
+The ar format has never been standardised.
+There are two common variants:
+the GNU format derived from SVR4,
+and the BSD format, which first appeared in 4.4BSD.
+The two differ primarily in their handling of filenames
+longer than 15 characters:
+the GNU/SVR4 variant writes a filename table at the beginning of the archive;
+the BSD format stores each long filename in an extension
+area adjacent to the entry.
+Libarchive can read both extensions,
+including archives that may include both types of long filenames.
+Programs using libarchive can write GNU/SVR4 format
+if they provide a filename table to be written into
+the archive before any of the entries.
+Any entries whose names are not in the filename table
+will be written using BSD-style long filenames.
+This can cause problems for programs such as
+GNU ld that do not support the BSD-style long filenames.
+.SS mtree
+Libarchive can read and write files in
+\fBmtree\fP(5)
+format.
+This format is not a true archive format, but rather a textual description
+of a file hierarchy in which each line specifies the name of a file and
+provides specific metadata about that file.
+Libarchive can read all of the keywords supported by both
+the NetBSD and FreeBSD versions of
+\fBmtree\fP(1),
+although many of the keywords cannot currently be stored in an
+Tn archive_entry
+object.
+When writing, libarchive supports use of the
+\fBarchive_write_set_options\fP(3)
+interface to specify which keywords should be included in the
+output.
+If libarchive was compiled with access to suitable
+cryptographic libraries (such as the OpenSSL libraries),
+it can compute hash entries such as
+\fBsha512\fP
+or
+\fBmd5\fP
+from file data being written to the mtree writer.
+.PP
+When reading an mtree file, libarchive will locate the corresponding
+files on disk using the
+\fBcontents\fP
+keyword if present or the regular filename.
+If it can locate and open the file on disk, it will use that
+to fill in any metadata that is missing from the mtree file
+and will read the file contents and return those to the program
+using libarchive.
+If it cannot locate and open the file on disk, libarchive
+will return an error for any attempt to read the entry
+body.

+.SH LIBRARY
+.ad l
+Lb libarchive
+.SH OVERVIEW
+.ad l
+The
+\fB\%libarchive\fP
+library provides a flexible interface for reading and writing
+streaming archive files such as tar and cpio.
+The library is inherently stream-oriented; readers serially iterate through
+the archive, writers serially add things to the archive.
+In particular, note that there is no built-in support for
+random access nor for in-place modification.
+.PP
+When reading an archive, the library automatically detects the
+format and the compression.
+The library currently has read support for:
+.RS 5
+.IP \(bu
+old-style tar archives,
+.IP \(bu
+most variants of the POSIX

+.RE
+The library automatically detects archives compressed with
+\fBgzip\fP(1),
+\fBbzip2\fP(1),
+or
+\fBcompress\fP(1)
+and decompresses them transparently.
+.PP
+When writing an archive, you can specify the compression
+to be used and the format to use.
+The library can write
+.RS 5
+.IP \(bu
+POSIX-standard
+``ustar''
+archives,
+.IP \(bu
+POSIX
+``pax interchange format''
+archives,
+.IP \(bu
+POSIX octet-oriented cpio archives,
+.IP \(bu
+two different variants of shar archives.
+.RE
+Pax interchange format is an extension of the tar archive format that
+eliminates essentially all of the limitations of historic tar formats
+in a standard fashion that is supported
+by POSIX-compliant
+\fBpax\fP(1)
+implementations on many systems as well as several newer implementations of
+\fBtar\fP(1).
+Note that the default write format will suppress the pax extended
+attributes for most entries; explicitly requesting pax format will
+enable those attributes for all entries.
+.PP
+The read and write APIs are accessed through the
+\fB\%archive_read_XXX\fP()
+functions and the
+\fB\%archive_write_XXX\fP()
+functions, respectively, and either can be used independently
+of the other.
+.PP
+The rest of this manual page provides an overview of the library
+operation.
+More detailed information can be found in the individual manual
+pages for each API or utility function.
+.SH READING AN ARCHIVE
+.ad l
+To read an archive, you must first obtain an initialized
+Tn struct archive
+object from
+\fB\%archive_read_new\fP().
+You can then modify this object for the desired operations with the
+various
+\fB\%archive_read_set_XXX\fP()
+and
+\fB\%archive_read_support_XXX\fP()
+functions.
+In particular, you will need to invoke appropriate
+\fB\%archive_read_support_XXX\fP()
+functions to enable the corresponding compression and format
+support.
+Note that these latter functions perform two distinct operations:
+they cause the corresponding support code to be linked into your
+program, and they enable the corresponding auto-detect code.
+Unless you have specific constraints, you will generally want
+to invoke
+\fB\%archive_read_support_compression_all\fP()
+and
+\fB\%archive_read_support_format_all\fP()
+to enable auto-detect for all formats and compression types
+currently supported by the library.
+.PP
+Once you have prepared the
+Tn struct archive
+object, you call
+\fB\%archive_read_open\fP()
+to actually open the archive and prepare it for reading.
+There are several variants of this function;
+the most basic expects you to provide pointers to several
+functions that can provide blocks of bytes from the archive.
+There are convenience forms that allow you to
+specify a filename, file descriptor,
+\fIFILE *\fP
+object, or a block of memory from which to read the archive data.
+Note that the core library makes no assumptions about the
+size of the blocks read;
+callback functions are free to read whatever block size is
+most appropriate for the medium.
+.PP
+Each archive entry consists of a header followed by a certain
+amount of data.
+You can obtain the next header with
+\fB\%archive_read_next_header\fP(),
+which returns a pointer to an
+Tn struct archive_entry
+structure with information about the current archive element.
+If the entry is a regular file, then the header will be followed
+by the file data.
+You can use
+\fB\%archive_read_data\fP()
+(which works much like the
+\fBread\fP(2)
+system call)
+to read this data from the archive.
+You may prefer to use the higher-level
+\fB\%archive_read_data_skip\fP(),
+which reads and discards the data for this entry,
+\fB\%archive_read_data_to_buffer\fP(),
+which reads the data into an in-memory buffer,
+\fB\%archive_read_data_to_file\fP(),
+which copies the data to the provided file descriptor, or
+\fB\%archive_read_extract\fP(),
+which recreates the specified entry on disk and copies data
+from the archive.
+In particular, note that
+\fB\%archive_read_extract\fP()
+uses the
+Tn struct archive_entry
+structure that you provide it, which may differ from the
+entry just read from the archive.
+In particular, many applications will want to override the
+pathname, file permissions, or ownership.
+.PP
+Once you have finished reading data from the archive, you
+should call
+\fB\%archive_read_close\fP()
+to close the archive, then call
+\fB\%archive_read_finish\fP()
+to release all resources, including all memory allocated by the library.
+.PP
+The
+\fBarchive_read\fP(3)
+manual page provides more detailed calling information for this API.
+.SH WRITING AN ARCHIVE
+.ad l
+You use a similar process to write an archive.
+The
+\fB\%archive_write_new\fP()
+function creates an archive object useful for writing,
+the various
+\fB\%archive_write_set_XXX\fP()
+functions are used to set parameters for writing the archive, and
+\fB\%archive_write_open\fP()
+completes the setup and opens the archive for writing.
+.PP
+Individual archive entries are written in a three-step
+process:
+You first initialize a
+Tn struct archive_entry
+structure with information about the new entry.
+At a minimum, you should set the pathname of the
+entry and provide a
+\fIstruct\fP stat
+with a valid
+\fIst_mode\fP
+field, which specifies the type of object and
+\fIst_size\fP
+field, which specifies the size of the data portion of the object.
+The
+\fB\%archive_write_header\fP()
+function actually writes the header data to the archive.
+You can then use
+\fB\%archive_write_data\fP()
+to write the actual data.
+.PP
+After all entries have been written, use the
+\fB\%archive_write_finish\fP()
+function to release all resources.
+.PP
+The
+\fBarchive_write\fP(3)
+manual page provides more detailed calling information for this API.
+.SH DESCRIPTION
+.ad l
+Detailed descriptions of each function are provided by the
+corresponding manual pages.
+.PP
+All of the functions utilize an opaque
+Tn struct archive
+datatype that provides access to the archive contents.
+.PP
+The
+Tn struct archive_entry
+structure contains a complete description of a single archive
+entry.
+It uses an opaque interface that is fully documented in
+\fBarchive_entry\fP(3).
+.PP
+Users familiar with historic formats should be aware that the newer
+variants have eliminated most restrictions on the length of textual fields.
+Clients should not assume that filenames, link names, user names, or
+group names are limited in length.
+In particular, pax interchange format can easily accommodate pathnames
+in arbitrary character sets that exceed
+\fIPATH_MAX\fP.
+.SH RETURN VALUES
+.ad l
+Most functions return zero on success, non-zero on error.
+The return value indicates the general severity of the error, ranging
+from
+\fBARCHIVE_WARN\fP,
+which indicates a minor problem that should probably be reported
+to the user, to
+\fBARCHIVE_FATAL\fP,
+which indicates a serious problem that will prevent any further
+operations on this archive.
+On error, the
+\fB\%archive_errno\fP()
+function can be used to retrieve a numeric error code (see
+\fBerrno\fP(2)).
+The
+\fB\%archive_error_string\fP()
+returns a textual error message suitable for display.
+.PP
+\fB\%archive_read_new\fP()
+and
+\fB\%archive_write_new\fP()
+return pointers to an allocated and initialized
+Tn struct archive
+object.
+.PP
+\fB\%archive_read_data\fP()
+and
+\fB\%archive_write_data\fP()
+return a count of the number of bytes actually read or written.
+A value of zero indicates the end of the data for this entry.
+A negative value indicates an error, in which case the
+\fB\%archive_errno\fP()
+and
+\fB\%archive_error_string\fP()
+functions can be used to obtain more information.
+.SH ENVIRONMENT

+\fBarchive_entry\fP(3)
+functions that are impacted by the currently-selected locale.

+Some archive formats support information that is not supported by

+.TH LIBARCHIVE 3 "April 16, 2007" ""
+.SH NAME
+.ad l
+\fB\%libarchive_internals\fP
+\- description of libarchive internal interfaces
+.SH OVERVIEW
+.ad l
+The
+\fB\%libarchive\fP
+library provides a flexible interface for reading and writing
+streaming archive files such as tar and cpio.
+Internally, it follows a modular layered design that should
+make it easy to add new archive and compression formats.
+.SH GENERAL ARCHITECTURE
+.ad l
+Externally, libarchive exposes most operations through an
+opaque, object-style interface.
+The
+\fBarchive_entry\fP(1)
+objects store information about a single filesystem object.
+The rest of the library provides facilities to write
+\fBarchive_entry\fP(1)
+objects to archive files,
+read them from archive files,
+and write them to disk.
+(There are plans to add a facility to read
+\fBarchive_entry\fP(1)
+objects from disk as well.)
+.PP
+The read and write APIs each have four layers: a public API
+layer, a format layer that understands the archive file format,
+a compression layer, and an I/O layer.
+The I/O layer is completely exposed to clients who can replace
+it entirely with their own functions.
+.PP
+In order to provide as much consistency as possible for clients,
+some public functions are virtualized.
+Eventually, it should be possible for clients to open
+an archive or disk writer, and then use a single set of
+code to select and write entries, regardless of the target.
+.SH READ ARCHITECTURE
+.ad l
+From the outside, clients use the
+\fBarchive_read\fP(3)
+API to manipulate an
+\fB\%archive\fP
+object to read entries and bodies from an archive stream.
+Internally, the
+\fB\%archive\fP
+object is cast to an
+\fB\%archive_read\fP
+object, which holds all read-specific data.
+The API has four layers:
+The lowest layer is the I/O layer.
+This layer can be overridden by clients, but most clients use
+the packaged I/O callbacks provided, for example, by
+\fBarchive_read_open_memory\fP(3),
+and
+\fBarchive_read_open_fd\fP(3).
+The compression layer calls the I/O layer to
+read bytes and decompresses them for the format layer.
+The format layer unpacks a stream of uncompressed bytes and
+creates
+\fB\%archive_entry\fP
+objects from the incoming data.
+The API layer tracks overall state
+(for example, it prevents clients from reading data before reading a header)
+and invokes the format and compression layer operations
+through registered function pointers.
+In particular, the API layer drives the format-detection process:
+When opening the archive, it reads an initial block of data
+and offers it to each registered compression handler.
+The one with the highest bid is initialized with the first block.
+Similarly, the format handlers are polled to see which handler
+is the best for each archive.
+(Prior to 2.4.0, the format bidders were invoked for each
+entry, but this design hindered error recovery.)
+.SS I/O Layer and Client Callbacks
+The read API goes to some lengths to be nice to clients.
+As a result, there are few restrictions on the behavior of
+the client callbacks.
+.PP
+The client read callback is expected to provide a block
+of data on each call.
+A zero-length return does indicate end of file, but otherwise
+blocks may be as small as one byte or as large as the entire file.
+In particular, blocks may be of different sizes.
+.PP
+The client skip callback returns the number of bytes actually
+skipped, which may be much smaller than the skip requested.
+The only requirement is that the skip not be larger.
+In particular, clients are allowed to return zero for any
+skip that they don't want to handle.
+The skip callback must never be invoked with a negative value.
+.PP
+Keep in mind that not all clients are reading from disk:
+clients reading from networks may provide different-sized
+blocks on every request and cannot skip at all;
+advanced clients may use
+\fBmmap\fP(2)
+to read the entire file into memory at once and return the
+entire file to libarchive as a single block;
+other clients may begin asynchronous I/O operations for the
+next block on each request.
+.SS Decompresssion Layer
+The decompression layer not only handles decompression,
+it also buffers data so that the format handlers see a
+much nicer I/O model.
+The decompression API is a two stage peek/consume model.
+A read_ahead request specifies a minimum read amount;
+the decompression layer must provide a pointer to at least
+that much data.
+If more data is immediately available, it should return more:
+the format layer handles bulk data reads by asking for a minimum
+of one byte and then copying as much data as is available.
+.PP
+A subsequent call to the
+\fB\%consume\fP()
+function advances the read pointer.
+Note that data returned from a
+\fB\%read_ahead\fP()
+call is guaranteed to remain in place until
+the next call to
+\fB\%read_ahead\fP().
+Intervening calls to
+\fB\%consume\fP()
+should not cause the data to move.
+.PP
+Skip requests must always be handled exactly.
+Decompression handlers that cannot seek forward should
+not register a skip handler;
+the API layer fills in a generic skip handler that reads and discards data.
+.PP
+A decompression handler has a specific lifecycle:
+.RS 5
+.TP
+Registration/Configuration
+When the client invokes the public support function,
+the decompression handler invokes the internal
+\fB\%__archive_read_register_compression\fP()
+function to provide bid and initialization functions.
+This function returns
+\fBNULL\fP
+on error or else a pointer to a
+\fBstruct\fP decompressor_t.
+This structure contains a
+\fIvoid\fP * config
+slot that can be used for storing any customization information.
+.TP
+Bid
+The bid function is invoked with a pointer and size of a block of data.
+The decompressor can access its config data
+through the
+\fIdecompressor\fP
+element of the
+\fBarchive_read\fP
+object.
+The bid function is otherwise stateless.
+In particular, it must not perform any I/O operations.
+.PP
+The value returned by the bid function indicates its suitability
+for handling this data stream.
+A bid of zero will ensure that this decompressor is never invoked.
+Return zero if magic number checks fail.
+Otherwise, your initial implementation should return the number of bits
+actually checked.
+For example, if you verify two full bytes and three bits of another
+byte, bid 19.
+Note that the initial block may be very short;
+be careful to only inspect the data you are given.
+(The current decompressors require two bytes for correct bidding.)
+.TP
+Initialize
+The winning bidder will have its init function called.
+This function should initialize the remaining slots of the
+\fIstruct\fP decompressor_t
+object pointed to by the
+\fIdecompressor\fP
+element of the
+\fIarchive_read\fP
+object.
+In particular, it should allocate any working data it needs
+in the
+\fIdata\fP
+slot of that structure.
+The init function is called with the block of data that
+was used for tasting.
+At this point, the decompressor is responsible for all I/O
+requests to the client callbacks.
+The decompressor is free to read more data as and when
+necessary.
+.TP
+Satisfy I/O requests
+The format handler will invoke the
+\fIread_ahead\fP,
+\fIconsume\fP,
+and
+\fIskip\fP
+functions as needed.
+.TP
+Finish
+The finish method is called only once when the archive is closed.
+It should release anything stored in the
+\fIdata\fP
+and
+\fIconfig\fP
+slots of the
+\fIdecompressor\fP
+object.
+It should not invoke the client close callback.
+.RE
+.SS Format Layer
+The read formats have a similar lifecycle to the decompression handlers:
+.RS 5
+.TP
+Registration
+Allocate your private data and initialize your pointers.
+.TP
+Bid
+Formats bid by invoking the
+\fB\%read_ahead\fP()
+decompression method but not calling the
+\fB\%consume\fP()
+method.
+This allows each bidder to look ahead in the input stream.
+Bidders should not look further ahead than necessary, as long
+look aheads put pressure on the decompression layer to buffer
+lots of data.
+Most formats only require a few hundred bytes of look ahead;
+look aheads of a few kilobytes are reasonable.
+(The ISO9660 reader sometimes looks ahead by 48k, which
+should be considered an upper limit.)
+.TP
+Read header
+The header read is usually the most complex part of any format.
+There are a few strategies worth mentioning:
+For formats such as tar or cpio, reading and parsing the header is
+straightforward since headers alternate with data.
+For formats that store all header data at the beginning of the file,
+the first header read request may have to read all headers into
+memory and store that data, sorted by the location of the file
+data.
+Subsequent header read requests will skip forward to the
+beginning of the file data and return the corresponding header.
+.TP
+Read Data
+The read data interface supports sparse files; this requires that
+each call return a block of data specifying the file offset and
+size.
+This may require you to carefully track the location so that you
+can return accurate file offsets for each read.
+Remember that the decompressor will return as much data as it has.
+Generally, you will want to request one byte,
+examine the return value to see how much data is available, and
+possibly trim that to the amount you can use.
+You should invoke consume for each block just before you return it.
+.TP
+Skip All Data
+The skip data call should skip over all file data and trailing padding.
+This is called automatically by the API layer just before each
+header read.
+It is also called in response to the client calling the public
+\fB\%data_skip\fP()
+function.
+.TP
+Cleanup
+On cleanup, the format should release all of its allocated memory.
+.RE

+.SH WRITE ARCHITECTURE
+.ad l
+The write API has a similar set of four layers:

+.SH WRITE_DISK ARCHITECTURE
+.ad l
+The write_disk API is intended to look just like the write API
+to clients.
+Since it does not handle multiple formats or compression, it
+is not layered internally.
+.SH GENERAL SERVICES
+.ad l
+The
+\fB\%archive_read\fP,
+\fB\%archive_write\fP,
+and
+\fB\%archive_write_disk\fP
+objects all contain an initial
+\fB\%archive\fP
+object which provides common support for a set of standard services.
+(Recall that ANSI/ISO C90 guarantees that you can cast freely between
+a pointer to a structure and a pointer to the first element of that
+structure.)
+The
+\fB\%archive\fP
+object has a magic value that indicates which API this object
+is associated with,
+slots for storing error information,
+and function pointers for virtualized API functions.
+.SH MISCELLANEOUS NOTES
+.ad l
+Connecting existing archiving libraries into libarchive is generally
+quite difficult.
+In particular, many existing libraries strongly assume that you
+are reading from a file; they seek forwards and backwards as necessary
+to locate various pieces of information.
+In contrast, libarchive never seeks backwards in its input, which
+sometimes requires very different approaches.
+.PP
+For example, libarchive's ISO9660 support operates very differently
+from most ISO9660 readers.
+The libarchive support utilizes a work-queue design that
+keeps a list of known entries sorted by their location in the input.
+Whenever libarchive's ISO9660 implementation is asked for the next
+header, checks this list to find the next item on the disk.
+Directories are parsed when they are encountered and new
+items are added to the list.
+This design relies heavily on the ISO9660 image being optimized so that
+directories always occur earlier on the disk than the files they
+describe.
+.PP
+Depending on the specific format, such approaches may not be possible.
+The ZIP format specification, for example, allows archivers to store
+key information only at the end of the file.
+In theory, it is possible to create ZIP archives that cannot
+be read without seeking.
+Fortunately, such archives are very rare, and libarchive can read
+most ZIP archives, though it cannot always extract as much information
+as a dedicated ZIP program.

+.SH NAME
+.ad l
+\fB\%mtree\fP
+\- format of mtree dir hierarchy files
+.SH DESCRIPTION
+.ad l
+The
+\fB\%mtree\fP
+format is a textual format that describes a collection of filesystem objects.
+Such files are typically used to create or verify directory hierarchies.
+.SS General Format
+An
+\fB\%mtree\fP
+file consists of a series of lines, each providing information
+about a single filesystem object.
+Leading whitespace is always ignored.
+.PP
+When encoding file or pathnames, any backslash character or
+character outside of the 95 printable ASCII characters must be
+encoded as a a backslash followed by three
+octal digits.
+When reading mtree files, any appearance of a backslash
+followed by three octal digits should be converted into the
+corresponding character.
+.PP
+Each line is interpreted independently as one of the following types:
+.RS 5
+.TP
+Signature
+The first line of any mtree file must begin with
+``#mtree''.
+If a file contains any full path entries, the first line should
+begin with
+``#mtree v2.0'',
+otherwise, the first line should begin with
+``#mtree v1.0''.
+.TP
+Blank
+Blank lines are ignored.
+.TP
+Comment
+Lines beginning with
+\fB#\fP
+are ignored.
+.TP
+Special
+Lines beginning with
+\fB/\fP
+are special commands that influence
+the interpretation of later lines.
+.TP
+Relative
+If the first whitespace-delimited word has no
+\fB/\fP
+characters,
+it is the name of a file in the current directory.
+Any relative entry that describes a directory changes the
+current directory.
+.TP
+dot-dot
+As a special case, a relative entry with the filename
+\fI\& ..\fP
+changes the current directory to the parent directory.
+Options on dot-dot entries are always ignored.
+.TP
+Full
+If the first whitespace-delimited word has a
+\fB/\fP
+character after
+the first character, it is the pathname of a file relative to the
+starting directory.
+There can be multiple full entries describing the same file.
+.RE
+.PP
+Some tools that process
+\fB\%mtree\fP
+files may require that multiple lines describing the same file
+occur consecutively.
+It is not permitted for the same file to be mentioned using
+both a relative and a full file specification.
+.SS Special commands
+Two special commands are currently defined:
+.RS 5
+.TP
+\fB/set\fP
+This command defines default values for one or more keywords.
+It is followed on the same line by one or more whitespace-separated
+keyword definitions.
+These definitions apply to all following files that do not specify
+a value for that keyword.
+.TP
+\fB/unset\fP
+This command removes any default value set by a previous
+\fB/set\fP
+command.
+It is followed on the same line by one or more keywords
+separated by whitespace.
+.RE
+.SS Keywords
+After the filename, a full or relative entry consists of zero
+or more whitespace-separated keyword definitions.
+Each such definition consists of a key from the following
+list immediately followed by an '=' sign
+and a value.
+Software programs reading mtree files should warn about
+unrecognized keywords.
+.PP
+Currently supported keywords are as follows:
+.RS 5
+.TP
+\fBcksum\fP
+The checksum of the file using the default algorithm specified by
+the
+\fBcksum\fP(1)
+utility.
+.TP
+\fBcontents\fP
+The full pathname of a file that holds the contents of this file.
+.TP
+\fBflags\fP
+The file flags as a symbolic name.
+See
+\fBchflags\fP(1)
+for information on these names.
+If no flags are to be set the string
+``none''
+may be used to override the current default.
+.TP
+\fBgid\fP
+The file group as a numeric value.
+.TP
+\fBgname\fP
+The file group as a symbolic name.

+.SH NAME
+.ad l
+\fB\%tar\fP
+\- format of tape archive files
+.SH DESCRIPTION
+.ad l
+The
+\fB\%tar\fP
+archive format collects any number of files, directories, and other
+file system objects (symbolic links, device nodes, etc.) into a single
+stream of bytes.
+The format was originally designed to be used with
+tape drives that operate with fixed-size blocks, but is widely used as
+a general packaging mechanism.
+.SS General Format
+A
+\fB\%tar\fP
+archive consists of a series of 512-byte records.
+Each file system object requires a header record which stores basic metadata
+(pathname, owner, permissions, etc.) and zero or more records containing any
+file data.
+The end of the archive is indicated by two records consisting
+entirely of zero bytes.
+.PP
+For compatibility with tape drives that use fixed block sizes,
+programs that read or write tar files always read or write a fixed
+number of records with each I/O operation.
+These
+``blocks''
+are always a multiple of the record size.
+The maximum block size supported by early
+implementations was 10240 bytes or 20 records.
+This is still the default for most implementations
+although block sizes of 1MiB (2048 records) or larger are
+commonly used with modern high-speed tape drives.
+(Note: the terms
+``block''
+and
+``record''
+here are not entirely standard; this document follows the
+convention established by John Gilmore in documenting
+\fB\%pdtar\fP.)
+.SS Old-Style Archive Format
+The original tar archive format has been extended many times to
+include additional information that various implementors found
+necessary.
+This section describes the variant implemented by the tar command
+included in
+At v7,
+which seems to be the earliest widely-used version of the tar program.
+.PP
+The header record for an old-style
+\fB\%tar\fP
+archive consists of the following:
+.RS 4
+.nf
+struct header_old_tar {
+       char name[100];
+       char mode[8];
+       char uid[8];
+       char gid[8];
+       char size[12];
+       char mtime[12];
+       char checksum[8];
+       char linkflag[1];
+       char linkname[100];
+       char pad[255];
+};
+.RE
+All unused bytes in the header record are filled with nulls.
+.RS 5
+.TP
+\fIname\fP
+Pathname, stored as a null-terminated string.
+Early tar implementations only stored regular files (including
+hardlinks to those files).
+One common early convention used a trailing "/" character to indicate
+a directory name, allowing directory permissions and owner information
+to be archived and restored.
+.TP
+\fImode\fP
+File mode, stored as an octal number in ASCII.
+.TP
+\fIuid\fP, \fIgid\fP
+User id and group id of owner, as octal numbers in ASCII.
+.TP
+\fIsize\fP
+Size of file, as octal number in ASCII.
+For regular files only, this indicates the amount of data
+that follows the header.
+In particular, this field was ignored by early tar implementations
+when extracting hardlinks.
+Modern writers should always store a zero length for hardlink entries.
+.TP
+\fImtime\fP
+Modification time of file, as an octal number in ASCII.
+This indicates the number of seconds since the start of the epoch,
+00:00:00 UTC January 1, 1970.
+Note that negative values should be avoided
+here, as they are handled inconsistently.
+.TP
+\fIchecksum\fP
+Header checksum, stored as an octal number in ASCII.
+To compute the checksum, set the checksum field to all spaces,
+then sum all bytes in the header using unsigned arithmetic.
+This field should be stored as six octal digits followed by a null and a space
+character.
+Note that many early implementations of tar used signed arithmetic
+for the checksum field, which can cause interoperability problems
+when transferring archives between systems.
+Modern robust readers compute the checksum both ways and accept the
+header if either computation matches.
+.TP
+\fIlinkflag\fP, \fIlinkname\fP
+In order to preserve hardlinks and conserve tape, a file
+with multiple links is only written to the archive the first
+time it is encountered.
+The next time it is encountered, the
+\fIlinkflag\fP
+is set to an ASCII
+Sq 1
+and the
+\fIlinkname\fP
+field holds the first name under which this file appears.
+(Note that regular files have a null value in the
+\fIlinkflag\fP
+field.)
+.RE
+.PP
+Early tar implementations varied in how they terminated these fields.
+The tar command in
+At v7
+used the following conventions (this is also documented in early BSD manpages):
+the pathname must be null-terminated;
+the mode, uid, and gid fields must end in a space and a null byte;
+the size and mtime fields must end in a space;
+the checksum is terminated by a null and a space.
+Early implementations filled the numeric fields with leading spaces.
+This seems to have been common practice until the
+IEEE Std 1003.1-1988 (``POSIX.1'')
+standard was released.
+For best portability, modern implementations should fill the numeric
+fields with leading zeros.
+.SS Pre-POSIX Archives
+An early draft of
+IEEE Std 1003.1-1988 (``POSIX.1'')
+served as the basis for John Gilmore's
+\fB\%pdtar\fP
+program and many system implementations from the late 1980s
+and early 1990s.
+These archives generally follow the POSIX ustar
+format described below with the following variations:
+.RS 5
+.IP \(bu
+The magic value is
+``ustar\ \&''
+(note the following space).
+The version field contains a space character followed by a null.
+.IP \(bu
+The numeric fields are generally filled with leading spaces
+(not leading zeros as recommended in the final standard).
+.IP \(bu
+The prefix field is often not used, limiting pathnames to
+the 100 characters of old-style archives.
+.RE
+.SS POSIX ustar Archives
+IEEE Std 1003.1-1988 (``POSIX.1'')
+defined a standard tar file format to be read and written
+by compliant implementations of
+\fBtar\fP(1).
+This format is often called the
+``ustar''
+format, after the magic value used
+in the header.
+(The name is an acronym for
+``Unix Standard TAR''.)
+It extends the historic format with new fields:
+.RS 4
+.nf
+struct header_posix_ustar {
+       char name[100];
+       char mode[8];
+       char uid[8];

+       char pad[12];
+};
+.RE
+.RS 5
+.TP
+\fItypeflag\fP
+Type of entry.
+POSIX extended the earlier
+\fIlinkflag\fP
+field with several new type values:
+.RS 5
+.TP
+``0''
+Regular file.
+NUL should be treated as a synonym, for compatibility purposes.
+.TP
+``1''
+Hard link.
+.TP
+``2''
+Symbolic link.
+.TP
+``3''
+Character device node.
+.TP
+``4''
+Block device node.
+.TP
+``5''
+Directory.
+.TP
+``6''
+FIFO node.
+.TP
+``7''
+Reserved.
+.TP
+Other
+A POSIX-compliant implementation must treat any unrecognized typeflag value
+as a regular file.
+In particular, writers should ensure that all entries
+have a valid filename so that they can be restored by readers that do not
+support the corresponding extension.
+Uppercase letters "A" through "Z" are reserved for custom extensions.
+Note that sockets and whiteout entries are not archivable.
+.RE
+It is worth noting that the
+\fIsize\fP
+field, in particular, has different meanings depending on the type.
+For regular files, of course, it indicates the amount of data
+following the header.
+For directories, it may be used to indicate the total size of all
+files in the directory, for use by operating systems that pre-allocate
+directory space.
+For all other types, it should be set to zero by writers and ignored
+by readers.
+.TP
+\fImagic\fP
+Contains the magic value
+``ustar''
+followed by a NUL byte to indicate that this is a POSIX standard archive.
+Full compliance requires the uname and gname fields be properly set.
+.TP
+\fIversion\fP
+Version.
+This should be
+``00''
+(two copies of the ASCII digit zero) for POSIX standard archives.
+.TP
+\fIuname\fP, \fIgname\fP
+User and group names, as null-terminated ASCII strings.
+These should be used in preference to the uid/gid values
+when they are set and the corresponding names exist on
+the system.
+.TP
+\fIdevmajor\fP, \fIdevminor\fP
+Major and minor numbers for character device or block device entry.
+.TP
+\fIname\fP, \fIprefix\fP
+If the pathname is too long to fit in the 100 bytes provided by the standard
+format, it can be split at any
+\fI/\fP
+character with the first portion going into the prefix field.
+If the prefix field is not empty, the reader will prepend
+the prefix value and a
+\fI/\fP
+character to the regular name field to obtain the full pathname.
+The standard does not require a trailing
+\fI/\fP
+character on directory names, though most implementations still
+include this for compatibility reasons.
+.RE
+.PP
+Note that all unused bytes must be set to
+.BR NUL.
+.PP
+Field termination is specified slightly differently by POSIX
+than by previous implementations.
+The
+\fImagic\fP,
+\fIuname\fP,
+and
+\fIgname\fP
+fields must have a trailing
+.BR NUL.
+The
+\fIpathname\fP,
+\fIlinkname\fP,
+and
+\fIprefix\fP
+fields must have a trailing
+.BR NUL
+unless they fill the entire field.
+(In particular, it is possible to store a 256-character pathname if it
+happens to have a
+\fI/\fP
+as the 156th character.)
+POSIX requires numeric fields to be zero-padded in the front, and requires
+them to be terminated with either space or
+.BR NUL
+characters.
+.PP
+Currently, most tar implementations comply with the ustar
+format, occasionally extending it by adding new fields to the
+blank area at the end of the header record.
+.SS Pax Interchange Format
+There are many attributes that cannot be portably stored in a
+POSIX ustar archive.
+IEEE Std 1003.1-2001 (``POSIX.1'')
+defined a
+``pax interchange format''
+that uses two new types of entries to hold text-formatted
+metadata that applies to following entries.
+Note that a pax interchange format archive is a ustar archive in every
+respect.
+The new data is stored in ustar-compatible archive entries that use the
+``x''
+or
+``g''
+typeflag.
+In particular, older implementations that do not fully support these
+extensions will extract the metadata into regular files, where the
+metadata can be examined as necessary.
+.PP
+An entry in a pax interchange format archive consists of one or
+two standard ustar entries, each with its own header and data.
+The first optional entry stores the extended attributes
+for the following entry.
+This optional first entry has an "x" typeflag and a size field that
+indicates the total size of the extended attributes.
+The extended attributes themselves are stored as a series of text-format
+lines encoded in the portable UTF-8 encoding.
+Each line consists of a decimal number, a space, a key string, an equals
+sign, a value string, and a new line.
+The decimal number indicates the length of the entire line, including the
+initial length field and the trailing newline.
+An example of such a field is:
+.RS 4
+25 ctime=1084839148.1212\en
+.RE
+Keys in all lowercase are standard keys.
+Vendors can add their own keys by prefixing them with an all uppercase
+vendor name and a period.
+Note that, unlike the historic header, numeric values are stored using
+decimal, not octal.
+A description of some common keys follows:
+.RS 5
+.TP
+\fBatime\fP, \fBctime\fP, \fBmtime\fP
+File access, inode change, and modification times.
+These fields can be negative or include a decimal point and a fractional value.
+.TP
+\fBuname\fP, \fBuid\fP, \fBgname\fP, \fBgid\fP
+User name, group name, and numeric UID and GID values.
+The user name and group name stored here are encoded in UTF8
+and can thus include non-ASCII characters.
+The UID and GID fields can be of arbitrary length.
+.TP
+\fBlinkpath\fP
+The full path of the linked-to file.
+Note that this is encoded in UTF8 and can thus include non-ASCII characters.
+.TP
+\fBpath\fP
+The full pathname of the entry.
+Note that this is encoded in UTF8 and can thus include non-ASCII characters.
+.TP
+\fBrealtime.*\fP, \fBsecurity.*\fP
+These keys are reserved and may be used for future standardization.
+.TP
+\fBsize\fP
+The size of the file.
+Note that there is no length limit on this field, allowing conforming
+archives to store files much larger than the historic 8GB limit.
+.TP
+\fBSCHILY.*\fP
+Vendor-specific attributes used by Joerg Schilling's
+\fB\%star\fP
+implementation.
+.TP
+\fBSCHILY.acl.access\fP, \fBSCHILY.acl.default\fP
+Stores the access and default ACLs as textual strings in a format
+that is an extension of the format specified by POSIX.1e draft 17.
+In particular, each user or group access specification can include a fourth
+colon-separated field with the numeric UID or GID.
+This allows ACLs to be restored on systems that may not have complete
+user or group information available (such as when NIS/YP or LDAP services
+are temporarily unavailable).
+.TP
+\fBSCHILY.devminor\fP, \fBSCHILY.devmajor\fP
+The full minor and major numbers for device nodes.
+.TP
+\fBSCHILY.fflags\fP
+The file flags.
+.TP
+\fBSCHILY.realsize\fP
+The full size of the file on disk.
+XXX explain? XXX
+.TP
+\fBSCHILY.dev,\fP \fBSCHILY.ino\fP, \fBSCHILY.nlinks\fP
+The device number, inode number, and link count for the entry.
+In particular, note that a pax interchange format archive using Joerg
+Schilling's
+\fBSCHILY.*\fP
+extensions can store all of the data from
+\fIstruct\fP stat.
+.TP
+\fBLIBARCHIVE.xattr.\fP \fInamespace\fP.\fIkey\fP
+Libarchive stores POSIX.1e-style extended attributes using
+keys of this form.
+The
+\fIkey\fP
+value is URL-encoded:
+All non-ASCII characters and the two special characters
+``=''
+and
+``%''
+are encoded as
+``%''
+followed by two uppercase hexadecimal digits.
+The value of this key is the extended attribute value
+encoded in base 64.
+XXX Detail the base-64 format here XXX
+.TP
+\fBVENDOR.*\fP
+XXX document other vendor-specific extensions XXX
+.RE
+.PP
+Any values stored in an extended attribute override the corresponding
+values in the regular tar header.
+Note that compliant readers should ignore the regular fields when they
+are overridden.
+This is important, as existing archivers are known to store non-compliant
+values in the standard header fields in this situation.
+There are no limits on length for any of these fields.
+In particular, numeric fields can be arbitrarily large.
+All text fields are encoded in UTF8.
+Compliant writers should store only portable 7-bit ASCII characters in
+the standard ustar header and use extended
+attributes whenever a text value contains non-ASCII characters.
+.PP
+In addition to the
+\fBx\fP
+entry described above, the pax interchange format
+also supports a
+\fBg\fP
+entry.
+The
+\fBg\fP
+entry is identical in format, but specifies attributes that serve as
+defaults for all subsequent archive entries.
+The
+\fBg\fP
+entry is not widely used.
+.PP
+Besides the new
+\fBx\fP
+and
+\fBg\fP
+entries, the pax interchange format has a few other minor variations
+from the earlier ustar format.
+The most troubling one is that hardlinks are permitted to have
+data following them.
+This allows readers to restore any hardlink to a file without
+having to rewind the archive to find an earlier entry.
+However, it creates complications for robust readers, as it is no longer
+clear whether or not they should ignore the size field for hardlink entries.
+.SS GNU Tar Archives
+The GNU tar program started with a pre-POSIX format similar to that
+described earlier and has extended it using several different mechanisms:
+It added new fields to the empty space in the header (some of which was later
+used by POSIX for conflicting purposes);
+it allowed the header to be continued over multiple records;
+and it defined new entries that modify following entries
+(similar in principle to the
+\fBx\fP
+entry described above, but each GNU special entry is single-purpose,
+unlike the general-purpose
+\fBx\fP
+entry).
+As a result, GNU tar archives are not POSIX compatible, although
+more lenient POSIX-compliant readers can successfully extract most
+GNU tar archives.

+GNU tar treats type "7" records identically to type "0" records,
+except on one obscure RTOS where they are used to indicate the
+pre-allocation of a contiguous file on disk.
+.TP
+D
+This indicates a directory entry.
+Unlike the POSIX-standard "5"
+typeflag, the header is followed by data records listing the names
+of files in this directory.
+Each name is preceded by an ASCII "Y"
+if the file is stored in this archive or "N" if the file is not
+stored in this archive.
+Each name is terminated with a null, and
+an extra null marks the end of the name list.
+The purpose of this
+entry is to support incremental backups; a program restoring from
+such an archive may wish to delete files on disk that did not exist
+in the directory when the archive was made.
+.PP
+Note that the "D" typeflag specifically violates POSIX, which requires
+that unrecognized typeflags be restored as normal files.
+In this case, restoring the "D" entry as a file could interfere
+with subsequent creation of the like-named directory.
+.TP
+K
+The data for this entry is a long linkname for the following regular entry.
+.TP
+L
+The data for this entry is a long pathname for the following regular entry.
+.TP
+M
+This is a continuation of the last file on the previous volume.
+GNU multi-volume archives guarantee that each volume begins with a valid
+entry header.
+To ensure this, a file may be split, with part stored at the end of one volume,
+and part stored at the beginning of the next volume.
+The "M" typeflag indicates that this entry continues an existing file.
+Such entries can only occur as the first or second entry
+in an archive (the latter only if the first entry is a volume label).
+The
+\fIsize\fP
+field specifies the size of this entry.
+The
+\fIoffset\fP
+field at bytes 369-380 specifies the offset where this file fragment
+begins.
+The
+\fIrealsize\fP
+field specifies the total size of the file (which must equal
+\fIsize\fP
+plus
+\fIoffset\fP).
+When extracting, GNU tar checks that the header file name is the one it is
+expecting, that the header offset is in the correct sequence, and that
+the sum of offset and size is equal to realsize.
+.TP
+N
+Type "N" records are no longer generated by GNU tar.
+They contained a
+list of files to be renamed or symlinked after extraction; this was
+originally used to support long names.
+The contents of this record
+are a text description of the operations to be done, in the form
+``Rename %s to %s\en''
+or
+``Symlink %s to %s\en ;''
+in either case, both
+filenames are escaped using K&R C syntax.
+Due to security concerns, "N" records are now generally ignored
+when reading archives.
+.TP
+S
+This is a
+``sparse''
+regular file.
+Sparse files are stored as a series of fragments.
+The header contains a list of fragment offset/length pairs.
+If more than four such entries are required, the header is
+extended as necessary with
+``extra''
+header extensions (an older format that is no longer used), or
+``sparse''
+extensions.
+.TP
+V
+The
+\fIname\fP
+field should be interpreted as a tape/volume header name.
+This entry should generally be ignored on extraction.
+.RE
+.TP
+\fImagic\fP
+The magic field holds the five characters
+``ustar''
+followed by a space.
+Note that POSIX ustar archives have a trailing null.
+.TP
+\fIversion\fP
+The version field holds a space character followed by a null.
+Note that POSIX ustar archives use two copies of the ASCII digit
+``0''.
+.TP
+\fIatime\fP, \fIctime\fP
+The time the file was last accessed and the time of
+last change of file information, stored in octal as with
+\fImtime\fP.
+.TP
+\fIlongnames\fP
+This field is apparently no longer used.
+.TP
+Sparse \fIoffset\fP / \fInumbytes\fP
+Each such structure specifies a single fragment of a sparse
+file.
+The two fields store values as octal numbers.
+The fragments are each padded to a multiple of 512 bytes
+in the archive.
+On extraction, the list of fragments is collected from the
+header (including any extension headers), and the data
+is then read and written to the file at appropriate offsets.
+.TP
+\fIisextended\fP
+If this is set to non-zero, the header will be followed by additional
+``sparse header''
+records.
+Each such record contains information about as many as 21 additional
+sparse blocks as shown here:
+.RS 4
+.nf
+struct gnu_sparse_header {
+       struct {
+               char offset[12];
+               char numbytes[12];
+       } sparse[21];
+       char    isextended[1];
+       char    padding[7];
+};
+.RE
+.TP
+\fIrealsize\fP
+A binary representation of the file's complete size, with a much larger range
+than the POSIX file size.
+In particular, with
+\fBM\fP
+type files, the current entry is only a portion of the file.
+In that case, the POSIX size field will indicate the size of this
+entry; the
+\fIrealsize\fP
+field will indicate the total size of the file.
+.RE
+.SS GNU tar pax archives
+GNU tar 1.14 (XXX check this XXX) and later will write
+pax interchange format archives when you specify the
+\fB\--posix\fP
+flag.
+This format uses custom keywords to store sparse file information.
+There have been three iterations of this support, referred to
+as
+``0.0'',
+``0.1'',
+and
+``1.0''.
+.RS 5
+.TP
+\fBGNU.sparse.numblocks\fP, \fBGNU.sparse.offset\fP, \fBGNU.sparse.numbytes\fP, \fBGNU.sparse.size\fP
+The
+``0.0''
+format used an initial
+\fBGNU.sparse.numblocks\fP
+attribute to indicate the number of blocks in the file, a pair of
+\fBGNU.sparse.offset\fP
+and
+\fBGNU.sparse.numbytes\fP
+to indicate the offset and size of each block,
+and a single
+\fBGNU.sparse.size\fP
+to indicate the full size of the file.
+This is not the same as the size in the tar header because the
+latter value does not include the size of any holes.
+This format required that the order of attributes be preserved and
+relied on readers accepting multiple appearances of the same attribute
+names, which is not officially permitted by the standards.
+.TP
+\fBGNU.sparse.map\fP
+The
+``0.1''
+format used a single attribute that stored a comma-separated
+list of decimal numbers.
+Each pair of numbers indicated the offset and size, respectively,
+of a block of data.
+This does not work well if the archive is extracted by an archiver
+that does not recognize this extension, since many pax implementations
+simply discard unrecognized attributes.
+.TP
+\fBGNU.sparse.major\fP, \fBGNU.sparse.minor\fP, \fBGNU.sparse.name\fP, \fBGNU.sparse.realsize\fP
+The
+``1.0''
+format stores the sparse block map in one or more 512-byte blocks
+prepended to the file data in the entry body.
+The pax attributes indicate the existence of this map
+(via the
+\fBGNU.sparse.major\fP
+and
+\fBGNU.sparse.minor\fP
+fields)
+and the full size of the file.
+The
+\fBGNU.sparse.name\fP
+holds the true name of the file.
+To avoid confusion, the name stored in the regular tar header
+is a modified name so that extraction errors will be apparent
+to users.
+.RE
+.SS Solaris Tar
+XXX More Details Needed XXX
+.PP
+Solaris tar (beginning with SunOS XXX 5.7 ?? XXX) supports an
+``extended''
+format that is fundamentally similar to pax interchange format,
+with the following differences:
+.RS 5
+.IP \(bu
+Extended attributes are stored in an entry whose type is
+\fBX\fP,
+not
+\fBx\fP,
+as used by pax interchange format.
+The detailed format of this entry appears to be the same
+as detailed above for the
+\fBx\fP
+entry.
+.IP \(bu
+An additional
+\fBA\fP
+entry is used to store an ACL for the following regular entry.
+The body of this entry contains a seven-digit octal number
+followed by a zero byte, followed by the
+textual ACL description.
+The octal value is the number of ACL entries
+plus a constant that indicates the ACL type: 01000000
+for POSIX.1e ACLs and 03000000 for NFSv4 ACLs.
+.RE
+.SS AIX Tar
+XXX More details needed XXX
+.SS Mac OS X Tar
+The tar distributed with Apple's Mac OS X stores most regular files
+as two separate entries in the tar archive.
+The two entries have the same name except that the first
+one has
+``._''
+added to the beginning of the name.
+This first entry stores the
+``resource fork''
+with additional attributes for the file.
+The Mac OS X
+\fB\%CopyFile\fP()
+API is used to separate a file on disk into separate
+resource and data streams and to reassemble those separate
+streams when the file is restored to disk.
+.SS Other Extensions
+One obvious extension to increase the size of files is to
+eliminate the terminating characters from the various
+numeric fields.
+For example, the standard only allows the size field to contain
+11 octal digits, reserving the twelfth byte for a trailing
+NUL character.
+Allowing 12 octal digits allows file sizes up to 64 GB.
+.PP
+Another extension, utilized by GNU tar, star, and other newer
+\fB\%tar\fP
+implementations, permits binary numbers in the standard numeric fields.
+This is flagged by setting the high bit of the first byte.
+This permits 95-bit values for the length and time fields
+and 63-bit values for the uid, gid, and device numbers.
+GNU tar supports this extension for the
+length, mtime, ctime, and atime fields.
+Joerg Schilling's star program supports this extension for
+all numeric fields.
+Note that this extension is largely obsoleted by the extended attribute
+record provided by the pax interchange format.
+.PP
+Another early GNU extension allowed base-64 values rather than octal.
+This extension was short-lived and is no longer supported by any
+implementation.

+
+DESCRIPTION
+     These functions create and manipulate data objects that represent entries
+     within an archive.  You can think of a struct archive_entry as a heavy-
+     duty version of struct stat: it includes everything from struct stat plus
+     associated pathname, textual group and user names, etc.  These objects
+     are used by libarchive(3) to represent the metadata associated with a
+     particular entry in an archive.
+
+   Create and Destroy
+     There are functions to allocate, destroy, clear, and copy archive_entry
+     objects:
+     archive_entry_clear()
+            Erases the object, resetting all internal fields to the same
+            state as a newly-created object.  This is provided to allow you
+            to quickly recycle objects without thrashing the heap.
+     archive_entry_clone()
+            A deep copy operation; all text fields are duplicated.
+     archive_entry_free()
+            Releases the struct archive_entry object.
+     archive_entry_new()
+            Allocate and return a blank struct archive_entry object.
+
+   Set and Get Functions
+     Most of the functions here set or read entries in an object.  Such func-
+     tions have one of the following forms:
+     archive_entry_set_XXXX()
+            Stores the provided data in the object.  In particular, for
+            strings, the pointer is stored, not the referenced string.
+     archive_entry_copy_XXXX()
+            As above, except that the referenced data is copied into the
+            object.
+     archive_entry_XXXX()
+            Returns the specified data.  In the case of strings, a const-
+            qualified pointer to the string is returned.
+     String data can be set or accessed as wide character strings or normal
+     char strings.  The functions that use wide character strings are suffixed
+     with _w.  Note that these are different representations of the same data:
+     For example, if you store a narrow string and read the corresponding wide
+     string, the object will transparently convert formats using the current
+     locale.  Similarly, if you store a wide string and then store a narrow
+     string for the same data, the previously-set wide string will be dis-
+     carded in favor of the new data.
+
+     There are a few set/get functions that merit additional description:
+     archive_entry_set_link()
+            This function sets the symlink field if it is already set.  Oth-
+            erwise, it sets the hardlink field.
+
+   File Flags
+     File flags are transparently converted between a bitmap representation
+     and a textual format.  For example, if you set the bitmap and ask for
+     text, the library will build a canonical text format.  However, if you
+     set a text format and request a text format, you will get back the same
+     text, even if it is ill-formed.  If you need to canonicalize a textual
+     flags string, you should first set the text form, then request the bitmap
+     form, then use that to set the bitmap form.  Setting the bitmap format
+     will clear the internal text representation and force it to be recon-
+     structed when you next request the text form.
+
+     The bitmap format consists of two integers, one containing bits that
+     should be set, the other specifying bits that should be cleared.  Bits
+     not mentioned in either bitmap will be ignored.  Usually, the bitmap of
+     bits to be cleared will be set to zero.  In unusual circumstances, you
+     can force a fully-specified set of file flags by setting the bitmap of
+     flags to clear to the complement of the bitmap of flags to set.  (This
+     differs from fflagstostr(3), which only includes names for set bits.)
+     Converting a bitmap to a textual string is a platform-specific operation;
+     bits that are not meaningful on the current platform will be ignored.
+
+     The canonical text format is a comma-separated list of flag names.  The
+     archive_entry_copy_fflags_text() and archive_entry_copy_fflags_text_w()
+     functions parse the provided text and sets the internal bitmap values.
+     This is a platform-specific operation; names that are not meaningful on
+     the current platform will be ignored.  The function returns a pointer to
+     the start of the first name that was not recognized, or NULL if every
+     name was recognized.  Note that every name--including names that follow
+     an unrecognized name--will be evaluated, and the bitmaps will be set to
+     reflect every name that is recognized.  (In particular, this differs from
+     strtofflags(3), which stops parsing at the first unrecognized name.)
+
+   ACL Handling
+     XXX This needs serious help.  XXX
+
+     An ``Access Control List'' (ACL) is a list of permissions that grant
+     access to particular users or groups beyond what would normally be pro-
+     vided by standard POSIX mode bits.  The ACL handling here addresses some
+     deficiencies in the POSIX.1e draft 17 ACL specification.  In particular,
+     POSIX.1e draft 17 specifies several different formats, but none of those
+     formats include both textual user/group names and numeric UIDs/GIDs.
+
+     XXX explain ACL stuff XXX

+DESCRIPTION
+     These functions provide a complete API for reading streaming archives.
+     The general process is to first create the struct archive object, set
+     options, initialize the reader, iterate over the archive headers and
+     associated data, then close the archive and release all resources.  The
+     following summary describes the functions in approximately the order they
+     would be used:
+     archive_read_new()
+            Allocates and initializes a struct archive object suitable for
+            reading from an archive.
+     archive_read_support_compression_bzip2(),
+            archive_read_support_compression_compress(),
+            archive_read_support_compression_gzip(),
+            archive_read_support_compression_lzma(),
+            archive_read_support_compression_none(),
+            archive_read_support_compression_xz()
+            Enables auto-detection code and decompression support for the
+            specified compression.  Returns ARCHIVE_OK if the compression is
+            fully supported, or ARCHIVE_WARN if the compression is supported
+            only through an external program.  Note that decompression using
+            an external program is usually slower than decompression through
+            built-in libraries.  Note that ``none'' is always enabled by
+            default.
+     archive_read_support_compression_all()
+            Enables all available decompression filters.
+     archive_read_support_compression_program()
+            Data is fed through the specified external program before being
+            dearchived.  Note that this disables automatic detection of the
+            compression format, so it makes no sense to specify this in con-
+            junction with any other decompression option.
+     archive_read_support_compression_program_signature()
+            This feeds data through the specified external program but only
+            if the initial bytes of the data match the specified signature
+            value.
+     archive_read_support_format_all(), archive_read_support_format_ar(),
+            archive_read_support_format_cpio(),
+            archive_read_support_format_empty(),
+            archive_read_support_format_iso9660(),
+            archive_read_support_format_mtree(),
+            archive_read_support_format_tar(),
+            archive_read_support_format_zip()
+            Enables support---including auto-detection code---for the speci-
+            fied archive format.  For example,
+            archive_read_support_format_tar() enables support for a variety
+            of standard tar formats, old-style tar, ustar, pax interchange
+            format, and many common variants.  For convenience,
+            archive_read_support_format_all() enables support for all avail-
+            able formats.  Only empty archives are supported by default.
+     archive_read_support_format_raw()
+            The ``raw'' format handler allows libarchive to be used to read
+            arbitrary data.  It treats any data stream as an archive with a
+            single entry.  The pathname of this entry is ``data''; all other
+            entry fields are unset.  This is not enabled by
+            archive_read_support_format_all() in order to avoid erroneous
+            handling of damaged archives.
+     archive_read_set_filter_options(), archive_read_set_format_options(),
+            archive_read_set_options()
+            Specifies options that will be passed to currently-registered
+            filters (including decompression filters) and/or format readers.
+            The argument is a comma-separated list of individual options.
+            Individual options have one of the following forms:
+            option=value
+                    The option/value pair will be provided to every module.
+                    Modules that do not accept an option with this name will
+                    ignore it.
+            option  The option will be provided to every module with a value
+                    of ``1''.
+            !option
+                    The option will be provided to every module with a NULL
+                    value.
+            module:option=value, module:option, module:!option
+                    As above, but the corresponding option and value will be
+                    provided only to modules whose name matches module.
+            The return value will be ARCHIVE_OK if any module accepts the
+            option, or ARCHIVE_WARN if no module accepted the option, or
+            ARCHIVE_FATAL if there was a fatal error while attempting to
+            process the option.
+
+            The currently supported options are:
+            Format iso9660
+                    joliet  Support Joliet extensions.  Defaults to enabled,
+                            use !joliet to disable.
+     archive_read_open()
+            The same as archive_read_open2(), except that the skip callback
+            is assumed to be NULL.
+     archive_read_open2()
+            Freeze the settings, open the archive, and prepare for reading
+            entries.  This is the most generic version of this call, which
+            accepts four callback functions.  Most clients will want to use
+            archive_read_open_filename(), archive_read_open_FILE(),
+            archive_read_open_fd(), or archive_read_open_memory() instead.
+            The library invokes the client-provided functions to obtain raw
+            bytes from the archive.
+     archive_read_open_FILE()
+            Like archive_read_open(), except that it accepts a FILE *
+            pointer.  This function should not be used with tape drives or
+            other devices that require strict I/O blocking.
+     archive_read_open_fd()
+            Like archive_read_open(), except that it accepts a file descrip-
+            tor and block size rather than a set of function pointers.  Note
+            that the file descriptor will not be automatically closed at end-
+            of-archive.  This function is safe for use with tape drives or
+            other blocked devices.
+     archive_read_open_file()
+            This is a deprecated synonym for archive_read_open_filename().
+     archive_read_open_filename()
+            Like archive_read_open(), except that it accepts a simple file-
+            name and a block size.  A NULL filename represents standard
+            input.  This function is safe for use with tape drives or other
+            blocked devices.
+     archive_read_open_memory()
+            Like archive_read_open(), except that it accepts a pointer and
+            size of a block of memory containing the archive data.
+     archive_read_next_header()
+            Read the header for the next entry and return a pointer to a
+            struct archive_entry.  This is a convenience wrapper around
+            archive_read_next_header2() that reuses an internal struct
+            archive_entry object for each request.
+     archive_read_next_header2()
+            Read the header for the next entry and populate the provided
+            struct archive_entry.
+     archive_read_data()
+            Read data associated with the header just read.  Internally, this
+            is a convenience function that calls archive_read_data_block()
+            and fills any gaps with nulls so that callers see a single con-
+            tinuous stream of data.
+     archive_read_data_block()
+            Return the next available block of data for this entry.  Unlike
+            archive_read_data(), the archive_read_data_block() function
+            avoids copying data and allows you to correctly handle sparse
+            files, as supported by some archive formats.  The library guaran-
+            tees that offsets will increase and that blocks will not overlap.
+            Note that the blocks returned from this function can be much
+            larger than the block size read from disk, due to compression and
+            internal buffer optimizations.
+     archive_read_data_skip()
+            A convenience function that repeatedly calls
+            archive_read_data_block() to skip all of the data for this ar-
+            chive entry.
+     archive_read_data_into_buffer()
+            This function is deprecated and will be removed.  Use
+            archive_read_data() instead.
+     archive_read_data_into_fd()
+            A convenience function that repeatedly calls
+            archive_read_data_block() to copy the entire entry to the pro-
+            vided file descriptor.
+     archive_read_extract(), archive_read_extract_set_skip_file()
+            A convenience function that wraps the corresponding
+            archive_write_disk(3) interfaces.  The first call to
+            archive_read_extract() creates a restore object using
+            archive_write_disk_new(3) and
+            archive_write_disk_set_standard_lookup(3), then transparently
+            invokes archive_write_disk_set_options(3),
+            archive_write_header(3), archive_write_data(3), and
+            archive_write_finish_entry(3) to create the entry on disk and
+            copy data into it.  The flags argument is passed unmodified to
+            archive_write_disk_set_options(3).
+     archive_read_extract2()
+            This is another version of archive_read_extract() that allows you
+            to provide your own restore object.  In particular, this allows
+            you to override the standard lookup functions using
+            archive_write_disk_set_group_lookup(3), and
+            archive_write_disk_set_user_lookup(3).  Note that
+            archive_read_extract2() does not accept a flags argument; you
+            should use archive_write_disk_set_options() to set the restore
+            options yourself.
+     archive_read_extract_set_progress_callback()
+            Sets a pointer to a user-defined callback that can be used for
+            updating progress displays during extraction.  The progress func-
+            tion will be invoked during the extraction of large regular
+            files.  The progress function will be invoked with the pointer
+            provided to this call.  Generally, the data pointed to should
+            include a reference to the archive object and the archive_entry
+            object so that various statistics can be retrieved for the
+            progress display.
+     archive_read_close()
+            Complete the archive and invoke the close callback.
+     archive_read_finish()
+            Invokes archive_read_close() if it was not invoked manually, then
+            release all resources.  Note: In libarchive 1.x, this function
+            was declared to return void, which made it impossible to detect
+            certain errors when archive_read_close() was invoked implicitly
+            from this function.  The declaration is corrected beginning with
+            libarchive 2.0.
+
+     Note that the library determines most of the relevant information about
+     the archive by inspection.  In particular, it automatically detects
+     gzip(1) or bzip2(1) compression and transparently performs the appropri-
+     ate decompression.  It also automatically detects the archive format.
+
+     A complete description of the struct archive and struct archive_entry
+     objects can be found in the overview manual page for libarchive(3).
+
+CLIENT CALLBACKS
+     The callback functions must match the following prototypes:
+
+          typedef ssize_t archive_read_callback(struct archive *,
+          void *client_data, const void **buffer)
+
+          typedef int archive_skip_callback(struct archive *,
+          void *client_data, size_t request)
+
+          typedef int archive_open_callback(struct archive *, void
+          *client_data)
+
+          typedef int archive_close_callback(struct archive *, void
+          *client_data)
+
+     The open callback is invoked by archive_open().  It should return
+     ARCHIVE_OK if the underlying file or data source is successfully opened.
+     If the open fails, it should call archive_set_error() to register an
+     error code and message and return ARCHIVE_FATAL.
+
+     The read callback is invoked whenever the library requires raw bytes from
+     the archive.  The read callback should read data into a buffer, set the
+     const void **buffer argument to point to the available data, and return a
+     count of the number of bytes available.  The library will invoke the read
+     callback again only after it has consumed this data.  The library imposes
+     no constraints on the size of the data blocks returned.  On end-of-file,
+     the read callback should return zero.  On error, the read callback should
+     invoke archive_set_error() to register an error code and message and
+     return -1.
+
+     The skip callback is invoked when the library wants to ignore a block of
+     data.  The return value is the number of bytes actually skipped, which
+     may differ from the request.  If the callback cannot skip data, it should
+     return zero.  If the skip callback is not provided (the function pointer
+     is NULL ), the library will invoke the read function instead and simply
+     discard the result.  A skip callback can provide significant performance
+     gains when reading uncompressed archives from slow disk drives or other
+     media that can skip quickly.
+
+     The close callback is invoked by archive_close when the archive process-
+     ing is complete.  The callback should return ARCHIVE_OK on success.  On
+     failure, the callback should invoke archive_set_error() to register an
+     error code and message and return ARCHIVE_FATAL.
+
+EXAMPLE
+     The following illustrates basic usage of the library.  In this example,
+     the callback functions are simply wrappers around the standard open(2),
+     read(2), and close(2) system calls.
+
+          void
+          list_archive(const char *name)
+          {
+            struct mydata *mydata;
+            struct archive *a;
+            struct archive_entry *entry;
+
+            mydata = malloc(sizeof(struct mydata));
+            a = archive_read_new();
+            mydata->name = name;
+            archive_read_support_compression_all(a);
+            archive_read_support_format_all(a);
+            archive_read_open(a, mydata, myopen, myread, myclose);
+            while (archive_read_next_header(a, &entry) == ARCHIVE_OK) {
+              printf("%s\n",archive_entry_pathname(entry));
+              archive_read_data_skip(a);
+            }
+            archive_read_finish(a);
+            free(mydata);
+          }
+
+          ssize_t
+          myread(struct archive *a, void *client_data, const void **buff)
+          {
+            struct mydata *mydata = client_data;
+

+
+RETURN VALUES
+     Most functions return zero on success, non-zero on error. The possible
+     return codes include: ARCHIVE_OK (the operation succeeded), ARCHIVE_WARN
+     (the operation succeeded but a non-critical error was encountered),
+     ARCHIVE_EOF (end-of-archive was encountered), ARCHIVE_RETRY (the opera-
+     tion failed but can be retried), and ARCHIVE_FATAL (there was a fatal
+     error; the archive should be closed immediately). Detailed error codes
+     and textual descriptions are available from the archive_errno() and
+     archive_error_string() functions.
+
+     archive_read_new() returns a pointer to a freshly allocated struct
+     archive object.  It returns NULL on error.
+
+     archive_read_data() returns a count of bytes actually read or zero at the
+     end of the entry. On error, a value of ARCHIVE_FATAL, ARCHIVE_WARN, or
+     ARCHIVE_RETRY is returned and an error code and textual description can
+     be retrieved from the archive_errno() and archive_error_string() func-
+     tions.
+
+     The library expects the client callbacks to behave similarly.  If there
+     is an error, you can use archive_set_error() to set an appropriate error
+     code and description, then return one of the non-zero values above.
+     (Note that the value eventually returned to the client may not be the
+     same; many errors that are not critical at the level of basic I/O can
+     prevent the archive from being properly read, thus most I/O errors even-
+     tually cause ARCHIVE_FATAL to be returned.)

+BUGS
+     Many traditional archiver programs treat empty files as valid empty ar-
+     chives.  For example, many implementations of tar(1) allow you to append
+     entries to an empty file. Of course, it is impossible to determine the
+     format of an empty file by inspecting the contents, so this library
+     treats empty files as having a special ``empty'' format.

+
+DESCRIPTION
+     These functions provide an API for reading information about objects on
+     disk.  In particular, they provide an interface for populating struct
+     archive_entry objects.
+
+     archive_read_disk_new()
+            Allocates and initializes a struct archive object suitable for
+            reading object information from disk.
+
+     archive_read_disk_set_symlink_logical(),
+            archive_read_disk_set_symlink_physical(),
+            archive_read_disk_set_symlink_hybrid()
+            This sets the mode used for handling symbolic links.  The
+            ``logical'' mode follows all symbolic links.  The ``physical''
+            mode does not follow any symbolic links.  The ``hybrid'' mode
+            currently behaves identically to the ``logical'' mode.
+
+     archive_read_disk_gname(), archive_read_disk_uname()
+            Returns a user or group name given a gid or uid value.  By
+            default, these always return a NULL string.
+
+     archive_read_disk_set_gname_lookup(),
+            archive_read_disk_set_uname_lookup()
+            These allow you to override the functions used for user and group
+            name lookups.  You may also provide a void * pointer to a private
+            data structure and a cleanup function for that data.  The cleanup
+            function will be invoked when the struct archive object is
+            destroyed or when new lookup functions are registered.
+
+     archive_read_disk_set_standard_lookup()
+            This convenience function installs a standard set of user and
+            group name lookup functions.  These functions use getpwid(3) and
+            getgrid(3) to convert ids to names, defaulting to NULL if the
+            names cannot be looked up.  These functions also implement a sim-
+            ple memory cache to reduce the number of calls to getpwid(3) and
+            getgrid(3).
+
+     archive_read_disk_entry_from_file()
+            Populates a struct archive_entry object with information about a
+            particular file.  The archive_entry object must have already been
+            created with archive_entry_new(3) and at least one of the source
+            path or path fields must already be set.  (If both are set, the
+            source path will be used.)
+
+            Information is read from disk using the path name from the struct
+            archive_entry object.  If a file descriptor is provided, some
+            information will be obtained using that file descriptor, on plat-
+            forms that support the appropriate system calls.
+
+            If a pointer to a struct stat is provided, information from that
+            structure will be used instead of reading from the disk where
+            appropriate.  This can provide performance benefits in scenarios
+            where struct stat information has already been read from the disk
+            as a side effect of some other operation.  (For example, direc-
+            tory traversal libraries often provide this information.)
+
+            Where necessary, user and group ids are converted to user and
+            group names using the currently registered lookup functions
+            above.  This affects the file ownership fields and ACL values in
+            the struct archive_entry object.
+
+     archive_read_close()
+            This currently does nothing.
+
+     archive_write_finish()
+            Invokes archive_write_close() if it was not invoked manually,
+            then releases all resources.
+     More information about the struct archive object and the overall design
+     of the library can be found in the libarchive(3) overview.
+
+EXAMPLE
+     The following illustrates basic usage of the library by showing how to
+     use it to copy an item on disk into an archive.
+
+          void
+          file_to_archive(struct archive *a, const char *name)
+          {
+            char buff[8192];
+            size_t bytes_read;
+            struct archive *ard;
+            struct archive_entry *entry;
+            int fd;
+
+            ard = archive_read_disk_new();
+            archive_read_disk_set_standard_lookup(ard);
+            entry = archive_entry_new();
+            fd = open(name, O_RDONLY);
+            if (fd < 0)
+               return;
+            archive_entry_copy_sourcepath(entry, name);
+            archive_read_disk_entry_from_file(ard, entry, fd, NULL);
+            archive_write_header(a, entry);
+            while ((bytes_read = read(fd, buff, sizeof(buff))) > 0)
+              archive_write_data(a, buff, bytes_read);
+            archive_write_finish_entry(a);
+            archive_read_finish(ard);
+            archive_entry_free(entry);
+          }
+
+RETURN VALUES
+     Most functions return ARCHIVE_OK (zero) on success, or one of several
+     negative error codes for errors.  Specific error codes include:
+     ARCHIVE_RETRY for operations that might succeed if retried, ARCHIVE_WARN
+     for unusual conditions that do not prevent further operations, and
+     ARCHIVE_FATAL for serious errors that make remaining operations impossi-
+     ble.  The archive_errno(3) and archive_error_string(3) functions can be
+     used to retrieve an appropriate error code and a textual error message.
+     (See archive_util(3) for details.)
+
+     archive_read_disk_new() returns a pointer to a newly-allocated struct
+     archive object or NULL if the allocation failed for any reason.
+
+     archive_read_disk_gname() and archive_read_disk_uname() return const char
+     * pointers to the textual name or NULL if the lookup failed for any rea-
+     son.  The returned pointer points to internal storage that may be reused
+     on the next call to either of these functions; callers should copy the
+     string if they need to continue accessing it.

+
+HISTORY
+     The libarchive library first appeared in FreeBSD 5.3.  The
+     archive_read_disk interface was added to libarchive 2.6 and first
+     appeared in FreeBSD 8.0.
+
+AUTHORS
+     The libarchive library was written by Tim Kientzle
+     <kientzle@freebsd.org>.
+
+BUGS
+     The ``standard'' user name and group name lookup functions are not the
+     defaults because getgrid(3) and getpwid(3) are sometimes too large for
+     particular applications.  The current design allows the application
+     author to use a more compact implementation when appropriate.
+
+     The full list of metadata read from disk by
+     archive_read_disk_entry_from_file() is necessarily system-dependent.
+
+     The archive_read_disk_entry_from_file() function reads as much informa-
+     tion as it can from disk. Some method should be provided to limit this
+     so that clients who do not need ACLs, for instance, can avoid the extra
+     work needed to look up such information.
+
+     This API should provide a set of methods for walking a directory tree.
+     That would make it a direct parallel of the archive_read(3) API.  When
+     such methods are implemented, the ``hybrid'' symbolic link mode will make
+     sense.

+
+DESCRIPTION
+     These functions provide access to various information about the struct
+     archive object used in the libarchive(3) library.
+     archive_clear_error()
+            Clears any error information left over from a previous call.  Not
+            generally used in client code.
+     archive_compression()
+            Returns a numeric code indicating the current compression.  This
+            value is set by archive_read_open().
+     archive_compression_name()
+            Returns a text description of the current compression suitable
+            for display.
+     archive_copy_error()
+            Copies error information from one archive to another.
+     archive_errno()
+            Returns a numeric error code (see errno(2)) indicating the reason
+            for the most recent error return.
+     archive_error_string()
+            Returns a textual error message suitable for display.  The error
+            message here is usually more specific than that obtained from
+            passing the result of archive_errno() to strerror(3).
+     archive_file_count()
+            Returns a count of the number of files processed by this archive
+            object.  The count is incremented by calls to
+            archive_write_header or archive_read_next_header.
+     archive_format()
+            Returns a numeric code indicating the format of the current ar-
+            chive entry.  This value is set by a successful call to
+            archive_read_next_header().  Note that it is common for this
+            value to change from entry to entry.  For example, a tar archive
+            might have several entries that utilize GNU tar extensions and
+            several entries that do not.  These entries will have different
+            format codes.
+     archive_format_name()
+            A textual description of the format of the current entry.
+     archive_set_error()
+            Sets the numeric error code and error description that will be
+            returned by archive_errno() and archive_error_string().  This
+            function should be used within I/O callbacks to set system-spe-
+            cific error codes and error descriptions.  This function accepts
+            a printf-like format string and arguments.  However, you should
+            be careful to use only the following printf format specifiers:
+            ``%c'', ``%d'', ``%jd'', ``%jo'', ``%ju'', ``%jx'', ``%ld'',
+            ``%lo'', ``%lu'', ``%lx'', ``%o'', ``%u'', ``%s'', ``%x'',
+            ``%%''.  Field-width specifiers and other printf features are not
+            uniformly supported and should not be used.

+     close the archive and release all resources.  The following summary
+     describes the functions in approximately the order they are ordinarily
+     used:

+     archive_write_new()
+            Allocates and initializes a struct archive object suitable for
+            writing a tar archive.
+
+     archive_write_set_bytes_per_block()
+            Sets the block size used for writing the archive data.  Every
+            call to the write callback function, except possibly the last
+            one, will use this value for the length.  The third parameter is
+            a boolean that specifies whether or not the final block written
+            will be padded to the full block size.  If it is zero, the last
+            block will not be padded.  If it is non-zero, padding will be
+            added both before and after compression.  The default is to use a
+            block size of 10240 bytes and to pad the last block.  Note that a
+            block size of zero will suppress internal blocking and cause
+            writes to be sent directly to the write callback as they occur.
+
+     archive_write_get_bytes_per_block()
+            Retrieve the block size to be used for writing.  A value of -1
+            here indicates that the library should use default values.  A
+            value of zero indicates that internal blocking is suppressed.
+
+     archive_write_set_bytes_in_last_block()
+            Sets the block size used for writing the last block.  If this
+            value is zero, the last block will be padded to the same size as
+            the other blocks.  Otherwise, the final block will be padded to a
+            multiple of this size.  In particular, setting it to 1 will cause
+            the final block to not be padded.  For compressed output, any
+            padding generated by this option is applied only after the com-
+            pression.  The uncompressed data is always unpadded.  The default
+            is to pad the last block to the full block size (note that
+            archive_write_open_filename() will set this based on the file
+            type).  Unlike the other ``set'' functions, this function can be
+            called after the archive is opened.
+
+     archive_write_get_bytes_in_last_block()
+            Retrieve the currently-set value for last block size.  A value of
+            -1 here indicates that the library should use default values.

+            archive_write_set_format_ustar()
+            Sets the format that will be used for the archive.  The library
+            can write POSIX octet-oriented cpio format archives, POSIX-stan-
+            dard ``pax interchange'' format archives, traditional ``shar''
+            archives, enhanced ``binary'' shar archives that store a variety
+            of file attributes and handle binary files, and POSIX-standard
+            ``ustar'' archives.  The pax interchange format is a backwards-
+            compatible tar format that adds key/value attributes to each
+            entry and supports arbitrary filenames, linknames, uids, sizes,
+            etc.  ``Restricted pax interchange format'' is the library
+            default; this is the same as pax format, but suppresses the pax
+            extended header for most normal files.  In most cases, this will
+            result in ordinary ustar archives.

+
+     archive_write_set_compression_program()

+
+     archive_write_set_compressor_options(),

+            rated list of individual options.  Individual options have one of
+            the following forms:
+            option=value
+                    The option/value pair will be provided to every module.
+                    Modules that do not accept an option with this name will
+                    ignore it.
+            option  The option will be provided to every module with a value
+                    of ``1''.
+            !option
+                    The option will be provided to every module with a NULL
+                    value.
+            module:option=value, module:option, module:!option
+                    As above, but the corresponding option and value will be
+                    provided only to modules whose name matches module.
+            The return value will be ARCHIVE_OK if any module accepts the
+            option, or ARCHIVE_WARN if no module accepted the option, or
+            ARCHIVE_FATAL if there was a fatal error while attempting to
+            process the option.
+
+            The currently supported options are:
+            Compressor gzip
+                    compression-level
+                            The value is interpreted as a decimal integer
+                            specifying the gzip compression level.
+            Compressor xz
+                    compression-level
+                            The value is interpreted as a decimal integer
+                            specifying the compression level.
+            Format mtree
+                    cksum, device, flags, gid, gname, indent, link, md5,
+                            mode, nlink, rmd160, sha1, sha256, sha384,

+                            Enable a particular keyword in the mtree output.
+                            Prefix with an exclamation mark to disable the
+                            corresponding keyword.  The default is equivalent
+                            to ``device, flags, gid, gname, link, mode,

+                    use-set
+                            Enables generation of /set lines that specify
+                            default values for the following files and/or
+                            directories.

+
+     archive_write_open()
+            Freeze the settings, open the archive, and prepare for writing
+            entries.  This is the most generic form of this function, which
+            accepts pointers to three callback functions which will be
+            invoked by the compression layer to write the constructed ar-
+            chive.
+
+     archive_write_open_fd()
+            A convenience form of archive_write_open() that accepts a file
+            descriptor.  The archive_write_open_fd() function is safe for use
+            with tape drives or other block-oriented devices.
+
+     archive_write_open_FILE()
+            A convenience form of archive_write_open() that accepts a FILE *
+            pointer.  Note that archive_write_open_FILE() is not safe for
+            writing to tape drives or other devices that require correct
+            blocking.
+
+     archive_write_open_file()
+            A deprecated synonym for archive_write_open_filename().
+
+     archive_write_open_filename()
+            A convenience form of archive_write_open() that accepts a file-
+            name.  A NULL argument indicates that the output should be writ-
+            ten to standard output; an argument of ``-'' will open a file
+            with that name.  If you have not invoked
+            archive_write_set_bytes_in_last_block(), then
+            archive_write_open_filename() will adjust the last-block padding
+            depending on the file: it will enable padding when writing to
+            standard output or to a character or block device node, it will
+            disable padding otherwise.  You can override this by manually
+            invoking archive_write_set_bytes_in_last_block() before calling
+            archive_write_open().  The archive_write_open_filename() function
+            is safe for use with tape drives or other block-oriented devices.
+
+     archive_write_open_memory()
+            A convenience form of archive_write_open() that accepts a pointer
+            to a block of memory that will receive the archive.  The final
+            size_t * argument points to a variable that will be updated after
+            each write to reflect how much of the buffer is currently in use.
+            You should be careful to ensure that this variable remains allo-
+            cated until after the archive is closed.
+
+     archive_write_header()
+            Build and write a header using the data in the provided struct
+            archive_entry structure.  See archive_entry(3) for information on
+            creating and populating struct archive_entry objects.
+
+     archive_write_data()
+            Write data corresponding to the header just written.  Returns
+            number of bytes written or -1 on error.
+
+     archive_write_finish_entry()
+            Close out the entry just written.  In particular, this writes out
+            the final padding required by some formats.  Ordinarily, clients
+            never need to call this, as it is called automatically by
+            archive_write_next_header() and archive_write_close() as needed.
+
+     archive_write_close()
+            Complete the archive and invoke the close callback.
+
+     archive_write_finish()
+            Invokes archive_write_close() if it was not invoked manually,
+            then releases all resources.  Note that this function was
+            declared to return void in libarchive 1.x, which made it impossi-
+            ble to detect errors when archive_write_close() was invoked
+            implicitly from this function.  This is corrected beginning with
+            libarchive 2.0.
+     More information about the struct archive object and the overall design
+     of the library can be found in the libarchive(3) overview.
+
+IMPLEMENTATION
+     Compression support is built-in to libarchive, which uses zlib and bzlib
+     to handle gzip and bzip2 compression, respectively.
+
+CLIENT CALLBACKS
+     To use this library, you will need to define and register callback func-
+     tions that will be invoked to write data to the resulting archive.  These
+     functions are registered by calling archive_write_open():
+
+          typedef int archive_open_callback(struct archive *, void
+          *client_data)
+
+     The open callback is invoked by archive_write_open().  It should return
+     ARCHIVE_OK if the underlying file or data source is successfully opened.
+     If the open fails, it should call archive_set_error() to register an
+     error code and message and return ARCHIVE_FATAL.
+
+          typedef ssize_t archive_write_callback(struct archive *,
+          void *client_data, const void *buffer, size_t length)
+
+     The write callback is invoked whenever the library needs to write raw
+     bytes to the archive.  For correct blocking, each call to the write call-
+     back function should translate into a single write(2) system call.  This
+     is especially critical when writing archives to tape drives.  On success,
+     the write callback should return the number of bytes actually written.
+     On error, the callback should invoke archive_set_error() to register an
+     error code and message and return -1.
+
+          typedef int archive_close_callback(struct archive *, void
+          *client_data)
+
+     The close callback is invoked by archive_close when the archive process-
+     ing is complete.  The callback should return ARCHIVE_OK on success.  On
+     failure, the callback should invoke archive_set_error() to register an
+     error code and message and return ARCHIVE_FATAL.
+
+EXAMPLE
+     The following sketch illustrates basic usage of the library.  In this
+     example, the callback functions are simply wrappers around the standard
+     open(2), write(2), and close(2) system calls.

+
+RETURN VALUES
+     Most functions return ARCHIVE_OK (zero) on success, or one of several
+     non-zero error codes for errors.  Specific error codes include:
+     ARCHIVE_RETRY for operations that might succeed if retried, ARCHIVE_WARN
+     for unusual conditions that do not prevent further operations, and
+     ARCHIVE_FATAL for serious errors that make remaining operations impossi-
+     ble.  The archive_errno() and archive_error_string() functions can be
+     used to retrieve an appropriate error code and a textual error message.
+
+     archive_write_new() returns a pointer to a newly-allocated struct archive
+     object.
+
+     archive_write_data() returns a count of the number of bytes actually
+     written.  On error, -1 is returned and the archive_errno() and
+     archive_error_string() functions will return appropriate values.  Note
+     that if the client-provided write callback function returns a non-zero
+     value, that error will be propagated back to the caller through whatever
+     API function resulted in that call, which may include
+     archive_write_header(), archive_write_data(), archive_write_close(), or
+     archive_write_finish().  The client callback can call archive_set_error()
+     to provide values that can then be retrieved by archive_errno() and
+     archive_error_string().

+
+HISTORY
+     The libarchive library first appeared in FreeBSD 5.3.
+
+AUTHORS
+     The libarchive library was written by Tim Kientzle <kientzle@acm.org>.
+
+BUGS
+     There are many peculiar bugs in historic tar implementations that may
+     cause certain programs to reject archives written by this library.  For
+     example, several historic implementations calculated header checksums
+     incorrectly and will thus reject valid archives; GNU tar does not fully
+     support pax interchange format; some old tar implementations required
+     specific field terminations.
+
+     The default pax interchange format eliminates most of the historic tar
+     limitations and provides a generic key/value attribute facility for ven-
+     dor-defined extensions.  One oversight in POSIX is the failure to provide
+     a standard attribute for large device numbers.  This library uses
+     ``SCHILY.devminor'' and ``SCHILY.devmajor'' for device numbers that
+     exceed the range supported by the backwards-compatible ustar header.
+     These keys are compatible with Joerg Schilling's star archiver.  Other
+     implementations may not recognize these keys and will thus be unable to
+     correctly restore device nodes with large device numbers from archives
+     created by this library.

+DESCRIPTION
+     These functions provide a complete API for creating objects on disk from
+     struct archive_entry descriptions.  They are most naturally used when
+     extracting objects from an archive using the archive_read() interface.
+     The general process is to read struct archive_entry objects from an ar-
+     chive, then write those objects to a struct archive object created using
+     the archive_write_disk() family functions.  This interface is deliber-
+     ately very similar to the archive_write() interface used to write objects
+     to a streaming archive.
+
+     archive_write_disk_new()
+            Allocates and initializes a struct archive object suitable for
+            writing objects to disk.
+
+     archive_write_disk_set_skip_file()
+            Records the device and inode numbers of a file that should not be
+            overwritten.  This is typically used to ensure that an extraction
+            process does not overwrite the archive from which objects are
+            being read.  This capability is technically unnecessary but can
+            be a significant performance optimization in practice.
+
+     archive_write_disk_set_options()
+            The options field consists of a bitwise OR of one or more of the
+            following values:
+            ARCHIVE_EXTRACT_OWNER
+                    The user and group IDs should be set on the restored
+                    file.  By default, the user and group IDs are not
+                    restored.
+            ARCHIVE_EXTRACT_PERM
+                    Full permissions (including SGID, SUID, and sticky bits)
+                    should be restored exactly as specified, without obeying
+                    the current umask.  Note that SUID and SGID bits can only
+                    be restored if the user and group ID of the object on
+                    disk are correct.  If ARCHIVE_EXTRACT_OWNER is not speci-
+                    fied, then SUID and SGID bits will only be restored if
+                    the default user and group IDs of newly-created objects
+                    on disk happen to match those specified in the archive
+                    entry.  By default, only basic permissions are restored,
+                    and umask is obeyed.
+            ARCHIVE_EXTRACT_TIME
+                    The timestamps (mtime, ctime, and atime) should be
+                    restored.  By default, they are ignored.  Note that
+                    restoring of atime is not currently supported.
+            ARCHIVE_EXTRACT_NO_OVERWRITE
+                    Existing files on disk will not be overwritten.  By
+                    default, existing regular files are truncated and over-
+                    written; existing directories will have their permissions
+                    updated; other pre-existing objects are unlinked and
+                    recreated from scratch.
+            ARCHIVE_EXTRACT_UNLINK
+                    Existing files on disk will be unlinked before any
+                    attempt to create them.  In some cases, this can prove to
+                    be a significant performance improvement.  By default,
+                    existing files are truncated and rewritten, but the file
+                    is not recreated.  In particular, the default behavior
+                    does not break existing hard links.
+            ARCHIVE_EXTRACT_ACL
+                    Attempt to restore ACLs.  By default, extended ACLs are
+                    ignored.
+            ARCHIVE_EXTRACT_FFLAGS
+                    Attempt to restore extended file flags.  By default, file
+                    flags are ignored.
+            ARCHIVE_EXTRACT_XATTR
+                    Attempt to restore POSIX.1e extended attributes.  By
+                    default, they are ignored.
+            ARCHIVE_EXTRACT_SECURE_SYMLINKS
+                    Refuse to extract any object whose final location would
+                    be altered by a symlink on disk.  This is intended to
+                    help guard against a variety of mischief caused by ar-
+                    chives that (deliberately or otherwise) extract files
+                    outside of the current directory.  The default is not to
+                    perform this check.  If ARCHIVE_EXTRACT_UNLINK is speci-
+                    fied together with this option, the library will remove
+                    any intermediate symlinks it finds and return an error
+                    only if such symlink could not be removed.
+            ARCHIVE_EXTRACT_SECURE_NODOTDOT
+                    Refuse to extract a path that contains a .. element any-
+                    where within it.  The default is to not refuse such
+                    paths.  Note that paths ending in .. always cause an
+                    error, regardless of this flag.
+            ARCHIVE_EXTRACT_SPARSE
+                    Scan data for blocks of NUL bytes and try to recreate
+                    them with holes.  This results in sparse files, indepen-
+                    dent of whether the archive format supports or uses them.
+
+     archive_write_disk_set_group_lookup(),
+            archive_write_disk_set_user_lookup()
+            The struct archive_entry objects contain both names and ids that
+            can be used to identify users and groups.  These names and ids
+            describe the ownership of the file itself and also appear in ACL
+            lists.  By default, the library uses the ids and ignores the
+            names, but this can be overridden by registering user and group
+            lookup functions.  To register, you must provide a lookup func-
+            tion which accepts both a name and id and returns a suitable id.
+            You may also provide a void * pointer to a private data structure
+            and a cleanup function for that data.  The cleanup function will
+            be invoked when the struct archive object is destroyed.
+
+     archive_write_disk_set_standard_lookup()
+            This convenience function installs a standard set of user and
+            group lookup functions.  These functions use getpwnam(3) and
+            getgrnam(3) to convert names to ids, defaulting to the ids if the
+            names cannot be looked up.  These functions also implement a sim-
+            ple memory cache to reduce the number of calls to getpwnam(3) and
+            getgrnam(3).
+
+     archive_write_header()
+            Build and write a header using the data in the provided struct
+            archive_entry structure.  See archive_entry(3) for information on
+            creating and populating struct archive_entry objects.
+
+     archive_write_data()
+            Write data corresponding to the header just written.  Returns
+            number of bytes written or -1 on error.
+
+     archive_write_finish_entry()
+            Close out the entry just written.  Ordinarily, clients never need
+            to call this, as it is called automatically by
+            archive_write_next_header() and archive_write_close() as needed.
+
+     archive_write_close()
+            Set any attributes that could not be set during the initial
+            restore.  For example, directory timestamps are not restored ini-
+            tially because restoring a subsequent file would alter that time-
+            stamp.  Similarly, non-writable directories are initially created
+            with write permissions (so that their contents can be restored).
+            The archive_write_disk_new library maintains a list of all such
+            deferred attributes and sets them when this function is invoked.
+
+     archive_write_finish()
+            Invokes archive_write_close() if it was not invoked manually,
+            then releases all resources.
+     More information about the struct archive object and the overall design
+     of the library can be found in the libarchive(3) overview.  Many of these
+     functions are also documented under archive_write(3).
+
+RETURN VALUES
+     Most functions return ARCHIVE_OK (zero) on success, or one of several
+     non-zero error codes for errors.  Specific error codes include:
+     ARCHIVE_RETRY for operations that might succeed if retried, ARCHIVE_WARN
+     for unusual conditions that do not prevent further operations, and
+     ARCHIVE_FATAL for serious errors that make remaining operations impossi-
+     ble.  The archive_errno() and archive_error_string() functions can be
+     used to retrieve an appropriate error code and a textual error message.
+
+     archive_write_disk_new() returns a pointer to a newly-allocated struct
+     archive object.
+
+     archive_write_data() returns a count of the number of bytes actually
+     written.  On error, -1 is returned and the archive_errno() and
+     archive_error_string() functions will return appropriate values.

+
+HISTORY
+     The libarchive library first appeared in FreeBSD 5.3.  The
+     archive_write_disk interface was added to libarchive 2.0 and first
+     appeared in FreeBSD 6.3.
+
+AUTHORS
+     The libarchive library was written by Tim Kientzle <kientzle@acm.org>.
+
+BUGS
+     Directories are actually extracted in two distinct phases.  Directories
+     are created during archive_write_header(), but final permissions are not
+     set until archive_write_close().  This separation is necessary to cor-
+     rectly handle borderline cases such as a non-writable directory contain-
+     ing files, but can cause unexpected results.  In particular, directory
+     permissions are not fully restored until the archive is closed.  If you
+     use chdir(2) to change the current directory between calls to
+     archive_read_extract() or before calling archive_read_close(), you may
+     confuse the permission-setting logic with the result that directory per-
+     missions are restored incorrectly.
+
+     The library attempts to create objects with filenames longer than
+     PATH_MAX by creating prefixes of the full path and changing the current
+     directory.  Currently, this logic is limited in scope; the fixup pass
+     does not work correctly for such objects and the symlink security check
+     option disables the support for very long pathnames.
+
+     Restoring the path aa/../bb does create each intermediate directory.  In
+     particular, the directory aa is created as well as the final object bb.
+     In theory, this can be exploited to create an entire directory heirarchy
+     with a single request.  Of course, this does not work if the
+     ARCHIVE_EXTRACT_NODOTDOT option is specified.
+
+     Implicit directories are always created obeying the current umask.
+     Explicit objects are created obeying the current umask unless
+     ARCHIVE_EXTRACT_PERM is specified, in which case they current umask is
+     ignored.
+
+     SGID and SUID bits are restored only if the correct user and group could
+     be set.  If ARCHIVE_EXTRACT_OWNER is not specified, then no attempt is
+     made to set the ownership.  In this case, SGID and SUID bits are restored
+     only if the user and group of the final object happen to match those
+     specified in the entry.
+
+     The ``standard'' user-id and group-id lookup functions are not the
+     defaults because getgrnam(3) and getpwnam(3) are sometimes too large for
+     particular applications.  The current design allows the application
+     author to use a more compact implementation when appropriate.
+
+     There should be a corresponding archive_read_disk interface that walks a
+     directory heirarchy and returns archive entry objects.

+NAME
+     cpio -- copy files to and from archives
+
+SYNOPSIS
+     cpio {-i} [options] [pattern ...] [< archive]
+     cpio {-o} [options] < name-list [> archive]
+     cpio {-p} [options] dest-dir < name-list
+
+DESCRIPTION
+     cpio copies files between archives and directories.  This implementation
+     can extract from tar, pax, cpio, zip, jar, ar, and ISO 9660 cdrom images
+     and can create tar, pax, cpio, ar, and shar archives.
+
+     The first option to cpio is a mode indicator from the following list:
+     -i      Input.  Read an archive from standard input (unless overriden)
+            and extract the contents to disk or (if the -t option is speci-
+            fied) list the contents to standard output.  If one or more file
+            patterns are specified, only files matching one of the patterns
+            will be extracted.
+     -o      Output.  Read a list of filenames from standard input and produce
+            a new archive on standard output (unless overriden) containing
+            the specified items.
+     -p      Pass-through.  Read a list of filenames from standard input and
+            copy the files to the specified directory.
+
+OPTIONS
+     Unless specifically stated otherwise, options are applicable in all oper-
+     ating modes.
+
+     -0      Read filenames separated by NUL characters instead of newlines.
+            This is necessary if any of the filenames being read might con-
+            tain newlines.
+
+     -A      (o mode only) Append to the specified archive.  (Not yet imple-
+            mented.)
+
+     -a      (o and p modes) Reset access times on files after they are read.
+
+     -B      (o mode only) Block output to records of 5120 bytes.
+
+     -C size
+            (o mode only) Block output to records of size bytes.
+
+     -c      (o mode only) Use the old POSIX portable character format.
+            Equivalent to --format odc.
+
+     -d      (i and p modes) Create directories as necessary.
+
+     -E file
+            (i mode only) Read list of file name patterns from file to list
+            and extract.
+
+     -F file
+            Read archive from or write archive to file.
+
+     -f pattern
+            (i mode only) Ignore files that match pattern.
+
+     --format format
+            (o mode only) Produce the output archive in the specified format.
+            Supported formats include:
+
+            cpio     Synonym for odc.
+            newc     The SVR4 portable cpio format.
+            odc      The old POSIX.1 portable octet-oriented cpio format.
+            pax      The POSIX.1 pax format, an extension of the ustar for-
+                     mat.
+            ustar    The POSIX.1 tar format.
+
+            The default format is odc.  See libarchive_formats(5) for more
+            complete information about the formats currently supported by the
+            underlying libarchive(3) library.
+
+     -H format
+            Synonym for --format.
+
+     -h, --help
+            Print usage information.
+
+     -I file
+            Read archive from file.
+
+     -i      Input mode.  See above for description.
+
+     --insecure
+            (i and p mode only) Disable security checks during extraction or
+            copying.  This allows extraction via symbolic links and path
+            names containing `..' in the name.
+
+     -J      (o mode only) Compress the file with xz-compatible compression
+            before writing it.  In input mode, this option is ignored; xz
+            compression is recognized automatically on input.
+
+     -j      Synonym for -y.
+
+     -L      (o and p modes) All symbolic links will be followed.  Normally,
+            symbolic links are archived and copied as symbolic links.  With
+            this option, the target of the link will be archived or copied
+            instead.
+
+     -l      (p mode only) Create links from the target directory to the orig-
+            inal files, instead of copying.
+
+     -lzma   (o mode only) Compress the file with lzma-compatible compression
+            before writing it.  In input mode, this option is ignored; lzma
+            compression is recognized automatically on input.
+
+     -m      (i and p modes) Set file modification time on created files to
+            match those in the source.
+
+     -n      (i mode, only with -t) Display numeric uid and gid.  By default,
+            cpio displays the user and group names when they are provided in
+            the archive, or looks up the user and group names in the system
+            password database.
+
+     -no-preserve-owner
+            (i mode only) Do not attempt to restore file ownership.  This is
+            the default when run by non-root users.
+
+     -O file
+            Write archive to file.
+
+     -o      Output mode.  See above for description.
+
+     -p      Pass-through mode.  See above for description.
+
+     -preserve-owner
+            (i mode only) Restore file ownership.  This is the default when
+            run by the root user.
+
+     --quiet
+            Suppress unnecessary messages.
+
+     -R [user][:][group]
+            Set the owner and/or group on files in the output.  If group is
+            specified with no user (for example, -R :wheel) then the group
+            will be set but not the user.  If the user is specified with a
+            trailing colon and no group (for example, -R root:) then the
+            group will be set to the user's default group.  If the user is
+            specified with no trailing colon, then the user will be set but
+            not the group.  In -i and -p modes, this option can only be used
+            by the super-user.  (For compatibility, a period can be used in
+            place of the colon.)
+
+     -r      (All modes.)  Rename files interactively. For each file, a
+            prompt is written to /dev/tty containing the name of the file and
+            a line is read from /dev/tty.  If the line read is blank, the
+            file is skipped.  If the line contains a single period, the file
+            is processed normally.  Otherwise, the line is taken to be the
+            new name of the file.
+
+     -t      (i mode only) List the contents of the archive to stdout; do not
+            restore the contents to disk.
+
+     -u      (i and p modes) Unconditionally overwrite existing files. Ordi-
+            narily, an older file will not overwrite a newer file on disk.
+
+     -v      Print the name of each file to stderr as it is processed. With
+            -t, provide a detailed listing of each file.
+
+     --version
+            Print the program version information and exit.
+
+     -y      (o mode only) Compress the archive with bzip2-compatible compres-
+            sion before writing it.  In input mode, this option is ignored;
+            bzip2 compression is recognized automatically on input.
+
+     -Z      (o mode only) Compress the archive with compress-compatible com-
+            pression before writing it.  In input mode, this option is
+            ignored; compression is recognized automatically on input.
+
+     -z      (o mode only) Compress the archive with gzip-compatible compres-
+            sion before writing it.  In input mode, this option is ignored;
+            gzip compression is recognized automatically on input.

+     TZ        The timezone to use when displaying dates.  See environ(7) for
+               more information.
+
+EXIT STATUS
+     The cpio utility exits 0 on success, and >0 if an error occurs.
+
+EXAMPLES
+     The cpio command is traditionally used to copy file heirarchies in con-
+     junction with the find(1) command.  The first example here simply copies
+     all files from src to dest:
+          find src | cpio -pmud dest
+
+     By carefully selecting options to the find(1) command and combining it
+     with other standard utilities, it is possible to exercise very fine con-
+     trol over which files are copied. This next example copies files from
+     src to dest that are more than 2 days old and whose names match a partic-
+     ular pattern:
+          find src -mtime +2 | grep foo[bar] | cpio -pdmu dest
+
+     This example copies files from src to dest that are more than 2 days old
+     and which contain the word ``foobar'':
+          find src -mtime +2 | xargs grep -l foobar | cpio -pdmu dest
+
+COMPATIBILITY
+     The mode options i, o, and p and the options a, B, c, d, f, l, m, r, t,
+     u, and v comply with SUSv2.
+
+     The old POSIX.1 standard specified that only -i, -o, and -p were inter-
+     preted as command-line options.  Each took a single argument of a list of
+     modifier characters.  For example, the standard syntax allows -imu but
+     does not support -miu or -i -m -u, since m and u are only modifiers to
+     -i, they are not command-line options in their own right. The syntax
+     supported by this implementation is backwards-compatible with the stan-
+     dard.  For best compatibility, scripts should limit themselves to the
+     standard syntax.

+
+STANDARDS
+     There is no current POSIX standard for the cpio command; it appeared in
+     ISO/IEC 9945-1:1996 (``POSIX.1'') but was dropped from IEEE Std
+     1003.1-2001 (``POSIX.1'').
+
+     The cpio, ustar, and pax interchange file formats are defined by IEEE Std
+     1003.1-2001 (``POSIX.1'') for the pax command.
+
+HISTORY
+     The original cpio and find utilities were written by Dick Haight while
+     working in AT&T's Unix Support Group.  They first appeared in 1977 in
+     PWB/UNIX 1.0, the ``Programmer's Work Bench'' system developed for use
+     within AT&T.  They were first released outside of AT&T as part of System
+     III Unix in 1981. As a result, cpio actually predates tar, even though
+     it was not well-known outside of AT&T until some time later.
+
+     This is a complete re-implementation based on the libarchive(3) library.
+
+BUGS
+     The cpio archive format has several basic limitations: It does not store
+     user and group names, only numbers.  As a result, it cannot be reliably
+     used to transfer files between systems with dissimilar user and group
+     numbering.  Older cpio formats limit the user and group numbers to 16 or
+     18 bits, which is insufficient for modern systems.  The cpio archive for-
+     mats cannot support files over 4 gigabytes, except for the ``odc'' vari-
+     ant, which can support files up to 8 gigabytes.

+NAME
+     tar -- manipulate tape archives
+
+SYNOPSIS
+     tar [bundled-flags <args>] [<file> | <pattern> ...]
+     tar {-c} [options] [files | directories]
+     tar {-r | -u} -f archive-file [options] [files | directories]
+     tar {-t | -x} [options] [patterns]
+
+DESCRIPTION
+     tar creates and manipulates streaming archive files.  This implementation
+     can extract from tar, pax, cpio, zip, jar, ar, and ISO 9660 cdrom images
+     and can create tar, pax, cpio, ar, and shar archives.
+
+     The first synopsis form shows a ``bundled'' option word.  This usage is
+     provided for compatibility with historical implementations.  See COMPATI-
+     BILITY below for details.
+
+     The other synopsis forms show the preferred usage.  The first option to
+     tar is a mode indicator from the following list:
+     -c      Create a new archive containing the specified items.
+     -r      Like -c, but new entries are appended to the archive.  Note that
+            this only works on uncompressed archives stored in regular files.
+            The -f option is required.
+     -t      List archive contents to stdout.
+     -u      Like -r, but new entries are added only if they have a modifica-
+            tion date newer than the corresponding entry in the archive.
+            Note that this only works on uncompressed archives stored in reg-
+            ular files.  The -f option is required.
+     -x      Extract to disk from the archive. If a file with the same name
+            appears more than once in the archive, each copy will be
+            extracted, with later copies overwriting (replacing) earlier
+            copies.
+
+     In -c, -r, or -u mode, each specified file or directory is added to the
+     archive in the order specified on the command line.  By default, the con-
+     tents of each directory are also archived.
+
+     In extract or list mode, the entire command line is read and parsed
+     before the archive is opened.  The pathnames or patterns on the command
+     line indicate which items in the archive should be processed.  Patterns
+     are shell-style globbing patterns as documented in tcsh(1).
+
+OPTIONS
+     Unless specifically stated otherwise, options are applicable in all oper-
+     ating modes.
+
+     @archive
+            (c and r mode only) The specified archive is opened and the
+            entries in it will be appended to the current archive.  As a sim-
+            ple example,
+                  tar -c -f - newfile @original.tar
+            writes a new archive to standard output containing a file newfile
+            and all of the entries from original.tar.  In contrast,
+                  tar -c -f - newfile original.tar
+            creates a new archive with only two entries.  Similarly,
+                  tar -czf - --format pax @-
+            reads an archive from standard input (whose format will be deter-
+            mined automatically) and converts it into a gzip-compressed pax-
+            format archive on stdout.  In this way, tar can be used to con-
+            vert archives from one format to another.
+
+     -b blocksize
+            Specify the block size, in 512-byte records, for tape drive I/O.
+            As a rule, this argument is only needed when reading from or
+            writing to tape drives, and usually not even then as the default
+            block size of 20 records (10240 bytes) is very common.
+
+     -C directory
+            In c and r mode, this changes the directory before adding the
+            following files.  In x mode, change directories after opening the
+            archive but before extracting entries from the archive.
+
+     --check-links
+            (c and r modes only) Issue a warning message unless all links to
+            each file are archived.
+
+     --chroot
+            (x mode only) chroot() to the current directory after processing
+            any -C options and before extracting any files.
+
+     --exclude pattern
+            Do not process files or directories that match the specified pat-
+            tern.  Note that exclusions take precedence over patterns or
+            filenames specified on the command line.
+
+     --format format
+            (c, r, u mode only) Use the specified format for the created ar-
+            chive.  Supported formats include ``cpio'', ``pax'', ``shar'',
+            and ``ustar''.  Other formats may also be supported; see
+            libarchive-formats(5) for more information about currently-sup-
+            ported formats.  In r and u modes, when extending an existing ar-
+            chive, the format specified here must be compatible with the for-
+            mat of the existing archive on disk.
+
+     -f file
+            Read the archive from or write the archive to the specified file.
+            The filename can be - for standard input or standard output.  If
+            not specified, the default tape device will be used.  (On
+            FreeBSD, the default tape device is /dev/sa0.)
+
+     -H      (c and r mode only) Symbolic links named on the command line will
+            be followed; the target of the link will be archived, not the
+            link itself.
+
+     -h      (c and r mode only) Synonym for -L.
+
+     -I      Synonym for -T.
+
+     --include pattern
+            Process only files or directories that match the specified pat-
+            tern.  Note that exclusions specified with --exclude take prece-
+            dence over inclusions.  If no inclusions are explicitly speci-
+            fied, all entries are processed by default.  The --include option
+            is especially useful when filtering archives.  For example, the
+            command
+                  tar -c -f new.tar --include='*foo*' @old.tgz
+            creates a new archive new.tar containing only the entries from
+            old.tgz containing the string `foo'.
+
+     -j      (c mode only) Compress the resulting archive with bzip2(1).  In
+            extract or list modes, this option is ignored.  Note that, unlike
+            other tar implementations, this implementation recognizes bzip2
+            compression automatically when reading archives.
+
+     -k      (x mode only) Do not overwrite existing files.  In particular, if
+            a file appears more than once in an archive, later copies will
+            not overwrite earlier copies.
+
+     --keep-newer-files
+            (x mode only) Do not overwrite existing files that are newer than
+            the versions appearing in the archive being extracted.
+
+     -L      (c and r mode only) All symbolic links will be followed.  Nor-
+            mally, symbolic links are archived as such.  With this option,
+            the target of the link will be archived instead.
+
+     -l      This is a synonym for the --check-links option.
+
+     -m      (x mode only) Do not extract modification time.  By default, the
+            modification time is set to the time stored in the archive.
+
+     -n      (c, r, u modes only) Do not recursively archive the contents of
+            directories.
+
+     --newer date
+            (c, r, u modes only) Only include files and directories newer
+            than the specified date.  This compares ctime entries.
+
+     --newer-mtime date
+            (c, r, u modes only) Like --newer, except it compares mtime
+            entries instead of ctime entries.
+
+     --newer-than file
+            (c, r, u modes only) Only include files and directories newer
+            than the specified file.  This compares ctime entries.
+
+     --newer-mtime-than file
+            (c, r, u modes only) Like --newer-than, except it compares mtime
+            entries instead of ctime entries.
+
+     --nodump
+            (c and r modes only) Honor the nodump file flag by skipping this
+            file.
+
+     --null  (use with -I, -T, or -X) Filenames or patterns are separated by
+            null characters, not by newlines.  This is often used to read
+            filenames output by the -print0 option to find(1).
+
+     --numeric-owner
+            (x mode only) Ignore symbolic user and group names when restoring
+            archives to disk, only numeric uid and gid values will be obeyed.
+
+     -O      (x, t modes only) In extract (-x) mode, files will be written to
+            standard out rather than being extracted to disk.  In list (-t)
+            mode, the file listing will be written to stderr rather than the
+            usual stdout.
+
+     -o      (x mode) Use the user and group of the user running the program
+            rather than those specified in the archive.  Note that this has
+            no significance unless -p is specified, and the program is being
+            run by the root user.  In this case, the file modes and flags
+            from the archive will be restored, but ACLs or owner information
+            in the archive will be discarded.
+
+     -o      (c, r, u mode) A synonym for --format ustar
+
+     --one-file-system
+            (c, r, and u modes) Do not cross mount points.
+
+     --options options
+            Select optional behaviors for particular modules.  The argument
+            is a text string containing comma-separated keywords and values.
+            These are passed to the modules that handle particular formats to
+            control how those formats will behave.  Each option has one of
+            the following forms:
+            key=value
+                    The key will be set to the specified value in every mod-
+                    ule that supports it.  Modules that do not support this
+                    key will ignore it.
+            key     The key will be enabled in every module that supports it.
+                    This is equivalent to key=1.
+            !key    The key will be disabled in every module that supports
+                    it.
+            module:key=value, module:key, module:!key
+                    As above, but the corresponding key and value will be
+                    provided only to modules whose name matches module.
+            The currently supported modules and keys are:
+            iso9660:joliet
+                    Support Joliet extensions.  This is enabled by default,
+                    use !joliet or iso9660:!joliet to disable.
+            iso9660:rockridge
+                    Support Rock Ridge extensions.  This is enabled by
+                    default, use !rockridge or iso9660:!rockridge to disable.
+            gzip:compression-level
+                    A decimal integer from 0 to 9 specifying the gzip com-
+                    pression level.
+            xz:compression-level
+                    A decimal integer from 0 to 9 specifying the xz compres-
+                    sion level.
+            mtree:keyword
+                    The mtree writer module allows you to specify which mtree
+                    keywords will be included in the output.  Supported key-
+                    words include: cksum, device, flags, gid, gname, indent,
+                    link, md5, mode, nlink, rmd160, sha1, sha256, sha384,
+                    sha512, size, time, uid, uname.  The default is equiva-
+                    lent to: ``device, flags, gid, gname, link, mode, nlink,
+                    size, time, type, uid, uname''.
+            mtree:all
+                    Enables all of the above keywords.  You can also use
+                    mtree:!all to disable all keywords.
+            mtree:use-set
+                    Enable generation of /set lines in the output.
+            mtree:indent
+                    Produce human-readable output by indenting options and
+                    splitting lines to fit into 80 columns.
+            zip:compression=type
+                    Use type as compression method.  Supported values are
+                    store (uncompressed) and deflate (gzip algorithm).
+            If a provided option is not supported by any module, that is a
+            fatal error.
+
+     -P      Preserve pathnames.  By default, absolute pathnames (those that
+            begin with a / character) have the leading slash removed both
+            when creating archives and extracting from them.  Also, tar will
+            refuse to extract archive entries whose pathnames contain .. or
+            whose target directory would be altered by a symlink.  This
+            option suppresses these behaviors.
+
+     -p      (x mode only) Preserve file permissions.  Attempt to restore the
+            full permissions, including owner, file modes, file flags and
+            ACLs, if available, for each item extracted from the archive.  By
+            default, newly-created files are owned by the user running tar,
+            the file mode is restored for newly-created regular files, and
+            all other types of entries receive default permissions.  If tar
+            is being run by root, the default is to restore the owner unless
+            the -o option is also specified.
+
+     -q (--fast-read)
+            (x and t mode only) Extract or list only the first archive entry
+            that matches each pattern or filename operand.  Exit as soon as
+            each specified pattern or filename has been matched.  By default,
+            the archive is always read to the very end, since there can be
+            multiple entries with the same name and, by convention, later
+            entries overwrite earlier entries.  This option is provided as a
+            performance optimization.
+
+     -S      (x mode only) Extract files as sparse files.  For every block on
+            disk, check first if it contains only NULL bytes and seek over it
+            otherwise.  This works similiar to the conv=sparse option of dd.
+
+     --strip-components count
+            (x mode only) Remove the specified number of leading path ele-
+            ments.  Pathnames with fewer elements will be silently skipped.
+            Note that the pathname is edited after checking inclusion/exclu-
+            sion patterns but before security checks.
+
+     -s pattern
+            Modify file or archive member names according to pattern.  The
+            pattern has the format /old/new/[gps] where old is a basic regu-
+            lar expression, new is the replacement string of the matched
+            part, and the optional trailing letters modify how the replace-
+            ment is handled.  If old is not matched, the pattern is skipped.
+            Within new, ~ is substituted with the match, 1 to 9 with the con-
+            tent of the corresponding captured group.  The optional trailing
+            g specifies that matching should continue after the matched part
+            and stopped on the first unmatched pattern.  The optional trail-
+            ing s specifies that the pattern applies to the value of symbolic
+            links.  The optional trailing p specifies that after a successful
+            substitution the original path name and the new path name should
+            be printed to standard error.
+
+     -T filename
+            In x or t mode, tar will read the list of names to be extracted
+            from filename.  In c mode, tar will read names to be archived
+            from filename.  The special name ``-C'' on a line by itself will
+            cause the current directory to be changed to the directory speci-
+            fied on the following line.  Names are terminated by newlines
+            unless --null is specified.  Note that --null also disables the
+            special handling of lines containing ``-C''.
+
+     -U      (x mode only) Unlink files before creating them.  Without this
+            option, tar overwrites existing files, which preserves existing
+            hardlinks.  With this option, existing hardlinks will be broken,
+            as will any symlink that would affect the location of an
+            extracted file.
+
+     --use-compress-program program
+            Pipe the input (in x or t mode) or the output (in c mode) through
+            program instead of using the builtin compression support.
+
+     -v      Produce verbose output.  In create and extract modes, tar will
+            list each file name as it is read from or written to the archive.
+            In list mode, tar will produce output similar to that of ls(1).
+            Additional -v options will provide additional detail.
+
+     --version
+            Print version of tar and libarchive, and exit.
+
+     -w      Ask for confirmation for every action.
+
+     -X filename
+            Read a list of exclusion patterns from the specified file.  See
+            --exclude for more information about the handling of exclusions.
+
+     -y      (c mode only) Compress the resulting archive with bzip2(1).  In
+            extract or list modes, this option is ignored.  Note that, unlike
+            other tar implementations, this implementation recognizes bzip2
+            compression automatically when reading archives.
+
+     -z      (c mode only) Compress the resulting archive with gzip(1).  In
+            extract or list modes, this option is ignored.  Note that, unlike
+            other tar implementations, this implementation recognizes gzip
+            compression automatically when reading archives.
+
+     -Z      (c mode only) Compress the resulting archive with compress(1).
+            In extract or list modes, this option is ignored.  Note that,
+            unlike other tar implementations, this implementation recognizes
+            compress compression automatically when reading archives.
+
+ENVIRONMENT
+     The following environment variables affect the execution of tar:
+
+     LANG      The locale to use.  See environ(7) for more information.
+
+     TAPE      The default tape device.  The -f option overrides this.
+
+     TZ        The timezone to use when displaying dates.  See environ(7) for
+               more information.
+
+FILES
+     /dev/sa0  The default tape device, if not overridden by the TAPE envi-
+               ronment variable or the -f option.
+
+EXIT STATUS
+     The tar utility exits 0 on success, and >0 if an error occurs.
+
+EXAMPLES
+     The following creates a new archive called file.tar.gz that contains two
+     files source.c and source.h:
+          tar -czf file.tar.gz source.c source.h
+
+     To view a detailed table of contents for this archive:
+          tar -tvf file.tar.gz
+
+     To extract all entries from the archive on the default tape drive:
+          tar -x
+
+     To examine the contents of an ISO 9660 cdrom image:
+          tar -tf image.iso
+
+     To move file hierarchies, invoke tar as
+          tar -cf - -C srcdir . | tar -xpf - -C destdir
+     or more traditionally
+          cd srcdir ; tar -cf - . | (cd destdir ; tar -xpf -)
+
+     In create mode, the list of files and directories to be archived can also
+     include directory change instructions of the form -Cfoo/baz and archive
+     inclusions of the form @archive-file.  For example, the command line
+          tar -c -f new.tar foo1 @old.tgz -C/tmp foo2
+     will create a new archive new.tar.  tar will read the file foo1 from the
+     current directory and add it to the output archive.  It will then read
+     each entry from old.tgz and add those entries to the output archive.
+     Finally, it will switch to the /tmp directory and add foo2 to the output
+     archive.
+
+     An input file in mtree(5) format can be used to create an output archive
+     with arbitrary ownership, permissions, or names that differ from existing
+     data on disk:
+
+          $ cat input.mtree
+          #mtree
+          usr/bin uid=0 gid=0 mode=0755 type=dir
+          usr/bin/ls uid=0 gid=0 mode=0755 type=file content=myls
+          $ tar -cvf output.tar @input.mtree
+
+     The --newer and --newer-mtime switches accept a variety of common date
+     and time specifications, including ``12 Mar 2005 7:14:29pm'',
+     ``2005-03-12 19:14'', ``5 minutes ago'', and ``19:14 PST May 1''.
+
+     The --options argument can be used to control various details of archive
+     generation or reading.  For example, you can generate mtree output which
+     only contains type, time, and uid keywords:
+          tar -cf file.tar --format=mtree --options='!all,type,time,uid' dir
+     or you can set the compression level used by gzip or xz compression:
+          tar -czf file.tar --options='compression-level=9'.
+     For more details, see the explanation of the archive_read_set_options()
+     and archive_write_set_options() API calls that are described in
+     archive_read(3) and archive_write(3).
+
+COMPATIBILITY
+     The bundled-arguments format is supported for compatibility with historic
+     implementations.  It consists of an initial word (with no leading - char-
+     acter) in which each character indicates an option.  Arguments follow as
+     separate words.  The order of the arguments must match the order of the
+     corresponding characters in the bundled command word.  For example,
+          tar tbf 32 file.tar
+     specifies three flags t, b, and f.  The b and f flags both require argu-
+     ments, so there must be two additional items on the command line. The 32
+     is the argument to the b flag, and file.tar is the argument to the f
+     flag.
+
+     The mode options c, r, t, u, and x and the options b, f, l, m, o, v, and
+     w comply with SUSv2.
+
+     For maximum portability, scripts that invoke tar should use the bundled-
+     argument format above, should limit themselves to the c, t, and x modes,
+     and the b, f, m, v, and w options.
+
+     Additional long options are provided to improve compatibility with other
+     tar implementations.
+
+SECURITY
+     Certain security issues are common to many archiving programs, including
+     tar.  In particular, carefully-crafted archives can request that tar
+     extract files to locations outside of the target directory.  This can
+     potentially be used to cause unwitting users to overwrite files they did
+     not intend to overwrite.  If the archive is being extracted by the supe-
+     ruser, any file on the system can potentially be overwritten.  There are
+     three ways this can happen.  Although tar has mechanisms to protect
+     against each one, savvy users should be aware of the implications:
+
+     o      Archive entries can have absolute pathnames.  By default, tar
+            removes the leading / character from filenames before restoring
+            them to guard against this problem.
+
+     o      Archive entries can have pathnames that include .. components.
+            By default, tar will not extract files containing .. components
+            in their pathname.
+
+     o      Archive entries can exploit symbolic links to restore files to
+            other directories.  An archive can restore a symbolic link to
+            another directory, then use that link to restore a file into that
+            directory.  To guard against this, tar checks each extracted path
+            for symlinks.  If the final path element is a symlink, it will be
+            removed and replaced with the archive entry.  If -U is specified,
+            any intermediate symlink will also be unconditionally removed.
+            If neither -U nor -P is specified, tar will refuse to extract the
+            entry.
+     To protect yourself, you should be wary of any archives that come from
+     untrusted sources.  You should examine the contents of an archive with
+          tar -tf filename
+     before extraction.  You should use the -k option to ensure that tar will
+     not overwrite any existing files or the -U option to remove any pre-
+     existing files.  You should generally not extract archives while running
+     with super-user privileges.  Note that the -P option to tar disables the
+     security checks above and allows you to extract an archive while preserv-
+     ing any absolute pathnames, .. components, or symlinks to other directo-
+     ries.

+
+STANDARDS
+     There is no current POSIX standard for the tar command; it appeared in
+     ISO/IEC 9945-1:1996 (``POSIX.1'') but was dropped from IEEE Std
+     1003.1-2001 (``POSIX.1'').  The options used by this implementation were
+     developed by surveying a number of existing tar implementations as well
+     as the old POSIX specification for tar and the current POSIX specifica-
+     tion for pax.
+
+     The ustar and pax interchange file formats are defined by IEEE Std
+     1003.1-2001 (``POSIX.1'') for the pax command.
+
+HISTORY
+     A tar command appeared in Seventh Edition Unix, which was released in
+     January, 1979.  There have been numerous other implementations, many of
+     which extended the file format.  John Gilmore's pdtar public-domain
+     implementation (circa November, 1987) was quite influential, and formed
+     the basis of GNU tar.  GNU tar was included as the standard system tar in
+     FreeBSD beginning with FreeBSD 1.0.
+
+     This is a complete re-implementation based on the libarchive(3) library.
+
+BUGS
+     This program follows ISO/IEC 9945-1:1996 (``POSIX.1'') for the definition
+     of the -l option. Note that GNU tar prior to version 1.15 treated -l as
+     a synonym for the --one-file-system option.
+
+     The -C dir option may differ from historic implementations.
+
+     All archive output is written in correctly-sized blocks, even if the out-
+     put is being compressed.  Whether or not the last output block is padded
+     to a full block size varies depending on the format and the output
+     device.  For tar and cpio formats, the last block of output is padded to
+     a full block size if the output is being written to standard output or to
+     a character or block device such as a tape drive. If the output is being
+     written to a regular file, the last block will not be padded.  Many com-
+     pressors, including gzip(1) and bzip2(1), complain about the null padding
+     when decompressing an archive created by tar, although they still extract
+     it correctly.
+
+     The compression and decompression is implemented internally, so there may
+     be insignificant differences between the compressed output generated by
+          tar -czf - file
+     and that generated by
+          tar -cf - file | gzip
+
+     The default should be to read and write archives to the standard I/O
+     paths, but tradition (and POSIX) dictates otherwise.
+
+     The r and u modes require that the archive be uncompressed and located in
+     a regular file on disk.  Other archives can be modified using c mode with
+     the @archive-file extension.
+
+     To archive a file called @foo or -foo you must specify it as ./@foo or
+     ./-foo, respectively.
+
+     In create mode, a leading ./ is always removed.  A leading / is stripped
+     unless the -P option is specified.
+
+     There needs to be better support for file selection on both create and
+     extract.
+
+     There is not yet any support for multi-volume archives or for archiving
+     sparse files.
+
+     Converting between dissimilar archive formats (such as tar and cpio)
+     using the @- convention can cause hard link information to be lost.
+     (This is a consequence of the incompatible ways that different archive
+     formats store hardlink information.)
+
+     There are alternative long options for many of the short options that are
+     deliberately not documented.

+NAME
+     cpio -- format of cpio archive files
+
+DESCRIPTION
+     The cpio archive format collects any number of files, directories, and
+     other file system objects (symbolic links, device nodes, etc.) into a
+     single stream of bytes.
+
+   General Format
+     Each file system object in a cpio archive comprises a header record with
+     basic numeric metadata followed by the full pathname of the entry and the
+     file data.  The header record stores a series of integer values that gen-
+     erally follow the fields in struct stat.  (See stat(2) for details.)  The
+     variants differ primarily in how they store those integers (binary,
+     octal, or hexadecimal).  The header is followed by the pathname of the
+     entry (the length of the pathname is stored in the header) and any file
+     data.  The end of the archive is indicated by a special record with the
+     pathname ``TRAILER!!!''.
+
+   PWB format
+     XXX Any documentation of the original PWB/UNIX 1.0 format? XXX
+
+   Old Binary Format
+     The old binary cpio format stores numbers as 2-byte and 4-byte binary
+     values.  Each entry begins with a header in the following format:
+
+          struct header_old_cpio {
+                  unsigned short   c_magic;
+                  unsigned short   c_dev;
+                  unsigned short   c_ino;
+                  unsigned short   c_mode;
+                  unsigned short   c_uid;
+                  unsigned short   c_gid;
+                  unsigned short   c_nlink;
+                  unsigned short   c_rdev;
+                  unsigned short   c_mtime[2];
+                  unsigned short   c_namesize;
+                  unsigned short   c_filesize[2];
+          };
+
+     The unsigned short fields here are 16-bit integer values; the unsigned
+     int fields are 32-bit integer values.  The fields are as follows
+
+     magic   The integer value octal 070707.  This value can be used to deter-
+            mine whether this archive is written with little-endian or big-
+            endian integers.
+
+     dev, ino
+            The device and inode numbers from the disk.  These are used by
+            programs that read cpio archives to determine when two entries
+            refer to the same file.  Programs that synthesize cpio archives
+            should be careful to set these to distinct values for each entry.
+
+     mode    The mode specifies both the regular permissions and the file
+            type.  It consists of several bit fields as follows:
+            0170000  This masks the file type bits.
+            0140000  File type value for sockets.
+            0120000  File type value for symbolic links.  For symbolic links,
+                     the link body is stored as file data.
+            0100000  File type value for regular files.
+            0060000  File type value for block special devices.
+            0040000  File type value for directories.
+            0020000  File type value for character special devices.
+            0010000  File type value for named pipes or FIFOs.
+            0004000  SUID bit.
+            0002000  SGID bit.
+            0001000  Sticky bit.  On some systems, this modifies the behavior
+                     of executables and/or directories.
+            0000777  The lower 9 bits specify read/write/execute permissions
+                     for world, group, and user following standard POSIX con-
+                     ventions.
+
+     uid, gid
+            The numeric user id and group id of the owner.
+
+     nlink   The number of links to this file. Directories always have a
+            value of at least two here.  Note that hardlinked files include
+            file data with every copy in the archive.
+
+     rdev    For block special and character special entries, this field con-
+            tains the associated device number.  For all other entry types,
+            it should be set to zero by writers and ignored by readers.
+
+     mtime   Modification time of the file, indicated as the number of seconds
+            since the start of the epoch, 00:00:00 UTC January 1, 1970.  The
+            four-byte integer is stored with the most-significant 16 bits
+            first followed by the least-significant 16 bits.  Each of the two
+            16 bit values are stored in machine-native byte order.
+
+     namesize
+            The number of bytes in the pathname that follows the header.
+            This count includes the trailing NUL byte.
+
+     filesize
+            The size of the file.  Note that this archive format is limited
+            to four gigabyte file sizes.  See mtime above for a description
+            of the storage of four-byte integers.
+
+     The pathname immediately follows the fixed header.  If the namesize is
+     odd, an additional NUL byte is added after the pathname.  The file data
+     is then appended, padded with NUL bytes to an even length.
+
+     Hardlinked files are not given special treatment; the full file contents
+     are included with each copy of the file.
+
+   Portable ASCII Format
+     Version 2 of the Single UNIX Specification (``SUSv2'') standardized an
+     ASCII variant that is portable across all platforms.  It is commonly
+     known as the ``old character'' format or as the ``odc'' format.  It
+     stores the same numeric fields as the old binary format, but represents
+     them as 6-character or 11-character octal values.
+
+          struct cpio_odc_header {
+                  char    c_magic[6];
+                  char    c_dev[6];
+                  char    c_ino[6];
+                  char    c_mode[6];
+                  char    c_uid[6];
+                  char    c_gid[6];
+                  char    c_nlink[6];
+                  char    c_rdev[6];
+                  char    c_mtime[11];
+                  char    c_namesize[6];
+                  char    c_filesize[11];
+          };
+
+     The fields are identical to those in the old binary format.  The name and
+     file body follow the fixed header.  Unlike the old binary format, there
+     is no additional padding after the pathname or file contents.  If the
+     files being archived are themselves entirely ASCII, then the resulting
+     archive will be entirely ASCII, except for the NUL byte that terminates
+     the name field.
+
+   New ASCII Format
+     The "new" ASCII format uses 8-byte hexadecimal fields for all numbers and
+     separates device numbers into separate fields for major and minor num-
+     bers.
+
+          struct cpio_newc_header {
+                  char    c_magic[6];
+                  char    c_ino[8];
+                  char    c_mode[8];
+                  char    c_uid[8];
+                  char    c_gid[8];
+                  char    c_nlink[8];
+                  char    c_mtime[8];
+                  char    c_filesize[8];
+                  char    c_devmajor[8];
+                  char    c_devminor[8];
+                  char    c_rdevmajor[8];
+                  char    c_rdevminor[8];
+                  char    c_namesize[8];
+                  char    c_check[8];
+          };
+
+     Except as specified below, the fields here match those specified for the
+     old binary format above.
+
+     magic   The string ``070701''.
+
+     check   This field is always set to zero by writers and ignored by read-
+            ers.  See the next section for more details.
+
+     The pathname is followed by NUL bytes so that the total size of the fixed
+     header plus pathname is a multiple of four.  Likewise, the file data is
+     padded to a multiple of four bytes.  Note that this format supports only
+     4 gigabyte files (unlike the older ASCII format, which supports 8 giga-
+     byte files).
+
+     In this format, hardlinked files are handled by setting the filesize to
+     zero for each entry except the last one that appears in the archive.
+
+   New CRC Format
+     The CRC format is identical to the new ASCII format described in the pre-
+     vious section except that the magic field is set to ``070702'' and the
+     check field is set to the sum of all bytes in the file data.  This sum is
+     computed treating all bytes as unsigned values and using unsigned arith-
+     metic.  Only the least-significant 32 bits of the sum are stored.
+
+   HP variants
+     The cpio implementation distributed with HPUX used XXXX but stored device
+     numbers differently XXX.
+
+   Other Extensions and Variants
+     Sun Solaris uses additional file types to store extended file data,
+     including ACLs and extended attributes, as special entries in cpio ar-
+     chives.
+
+     XXX Others? XXX
+
+BUGS
+     The ``CRC'' format is mis-named, as it uses a simple checksum and not a
+     cyclic redundancy check.

+     The old binary format is limited to 16 bits for user id, group id,
+     device, and inode numbers.  It is limited to 4 gigabyte file sizes.
+
+     The old ASCII format is limited to 18 bits for the user id, group id,
+     device, and inode numbers.  It is limited to 8 gigabyte file sizes.
+
+     The new ASCII format is limited to 4 gigabyte file sizes.
+
+     None of the cpio formats store user or group names, which are essential
+     when moving files between systems with dissimilar user or group number-
+     ing.
+
+     Especially when writing older cpio variants, it may be necessary to map
+     actual device/inode values to synthesized values that fit the available
+     fields.  With very large filesystems, this may be necessary even for the
+     newer formats.

+
+HISTORY
+     The original cpio utility was written by Dick Haight while working in

+     the ``Programmer's Work Bench'' derived from Version 6 AT&T UNIX that was
+     used internally at AT&T.  Both the old binary and old character formats
+     were in use by 1980, according to the System III source released by SCO
+     under their ``Ancient Unix'' license.  The character format was adopted
+     as part of IEEE Std 1003.1-1988 (``POSIX.1'').  XXX when did "newc"

+NAME
+     libarchive-formats -- archive formats supported by the libarchive library
+
+DESCRIPTION
+     The libarchive(3) library reads and writes a variety of streaming archive
+     formats.  Generally speaking, all of these archive formats consist of a
+     series of ``entries''.  Each entry stores a single file system object,
+     such as a file, directory, or symbolic link.
+
+     The following provides a brief description of each format supported by
+     libarchive, with some information about recognized extensions or limita-
+     tions of the current library support.  Note that just because a format is
+     supported by libarchive does not imply that a program that uses
+     libarchive will support that format.  Applications that use libarchive
+     specify which formats they wish to support, though many programs do use
+     libarchive convenience functions to enable all supported formats.
+
+   Tar Formats
+     The libarchive(3) library can read most tar archives.  However, it only
+     writes POSIX-standard ``ustar'' and ``pax interchange'' formats.
+
+     All tar formats store each entry in one or more 512-byte records. The
+     first record is used for file metadata, including filename, timestamp,
+     and mode information, and the file data is stored in subsequent records.
+     Later variants have extended this by either appropriating undefined areas
+     of the header record, extending the header to multiple records, or by
+     storing special entries that modify the interpretation of subsequent
+     entries.
+
+     gnutar  The libarchive(3) library can read GNU-format tar archives.  It
+            currently supports the most popular GNU extensions, including
+            modern long filename and linkname support, as well as atime and
+            ctime data.  The libarchive library does not support multi-volume
+            archives, nor the old GNU long filename format.  It can read GNU
+            sparse file entries, including the new POSIX-based formats, but
+            cannot write GNU sparse file entries.
+
+     pax     The libarchive(3) library can read and write POSIX-compliant pax
+            interchange format archives.  Pax interchange format archives are
+            an extension of the older ustar format that adds a separate entry
+            with additional attributes stored as key/value pairs immediately
+            before each regular entry.  The presence of these additional
+            entries is the only difference between pax interchange format and
+            the older ustar format.  The extended attributes are of unlimited
+            length and are stored as UTF-8 Unicode strings.  Keywords defined
+            in the standard are in all lowercase; vendors are allowed to
+            define custom keys by preceding them with the vendor name in all
+            uppercase.  When writing pax archives, libarchive uses many of
+            the SCHILY keys defined by Joerg Schilling's ``star'' archiver
+            and a few LIBARCHIVE keys.  The libarchive library can read most
+            of the SCHILY keys and most of the GNU keys introduced by GNU
+            tar.  It silently ignores any keywords that it does not under-
+            stand.
+
+     restricted pax
+            The libarchive library can also write pax archives in which it
+            attempts to suppress the extended attributes entry whenever pos-
+            sible.  The result will be identical to a ustar archive unless
+            the extended attributes entry is required to store a long file
+            name, long linkname, extended ACL, file flags, or if any of the
+            standard ustar data (user name, group name, UID, GID, etc) cannot
+            be fully represented in the ustar header.  In all cases, the
+            result can be dearchived by any program that can read POSIX-com-
+            pliant pax interchange format archives.  Programs that correctly
+            read ustar format (see below) will also be able to read this for-
+            mat; any extended attributes will be extracted as separate files
+            stored in PaxHeader directories.
+
+     ustar   The libarchive library can both read and write this format.  This
+            format has the following limitations:
+            o   Device major and minor numbers are limited to 21 bits.  Nodes
+                with larger numbers will not be added to the archive.
+            o   Path names in the archive are limited to 255 bytes.  (Shorter
+                if there is no / character in exactly the right place.)
+            o   Symbolic links and hard links are stored in the archive with
+                the name of the referenced file.  This name is limited to 100
+                bytes.
+            o   Extended attributes, file flags, and other extended security
+                information cannot be stored.
+            o   Archive entries are limited to 8 gigabytes in size.
+            Note that the pax interchange format has none of these restric-
+            tions.
+
+     The libarchive library also reads a variety of commonly-used extensions
+     to the basic tar format.  These extensions are recognized automatically
+     whenever they appear.
+
+     Numeric extensions.
+            The POSIX standards require fixed-length numeric fields to be
+            written with some character position reserved for terminators.
+            Libarchive allows these fields to be written without terminator
+            characters.  This extends the allowable range; in particular,
+            ustar archives with this extension can support entries up to 64
+            gigabytes in size.  Libarchive also recognizes base-256 values in
+            most numeric fields.  This essentially removes all limitations on
+            file size, modification time, and device numbers.
+
+     Solaris extensions
+            Libarchive recognizes ACL and extended attribute records written
+            by Solaris tar.  Currently, libarchive only has support for old-
+            style ACLs; the newer NFSv4 ACLs are recognized but discarded.
+
+     The first tar program appeared in Seventh Edition Unix in 1979.  The
+     first official standard for the tar file format was the ``ustar'' (Unix
+     Standard Tar) format defined by POSIX in 1988.  POSIX.1-2001 extended the
+     ustar format to create the ``pax interchange'' format.
+
+   Cpio Formats
+     The libarchive library can read a number of common cpio variants and can
+     write ``odc'' and ``newc'' format archives.  A cpio archive stores each
+     entry as a fixed-size header followed by a variable-length filename and
+     variable-length data.  Unlike the tar format, the cpio format does only
+     minimal padding of the header or file data.  There are several cpio vari-
+     ants, which differ primarily in how they store the initial header: some
+     store the values as octal or hexadecimal numbers in ASCII, others as
+     binary values of varying byte order and length.
+
+     binary  The libarchive library transparently reads both big-endian and
+            little-endian variants of the original binary cpio format.  This
+            format used 32-bit binary values for file size and mtime, and
+            16-bit binary values for the other fields.
+
+     odc     The libarchive library can both read and write this POSIX-stan-
+            dard format, which is officially known as the ``cpio interchange
+            format'' or the ``octet-oriented cpio archive format'' and some-
+            times unofficially referred to as the ``old character format''.
+            This format stores the header contents as octal values in ASCII.
+            It is standard, portable, and immune from byte-order confusion.
+            File sizes and mtime are limited to 33 bits (8GB file size),
+            other fields are limited to 18 bits.
+
+     SVR4    The libarchive library can read both CRC and non-CRC variants of
+            this format.  The SVR4 format uses eight-digit hexadecimal values
+            for all header fields.  This limits file size to 4GB, and also
+            limits the mtime and other fields to 32 bits.  The SVR4 format
+            can optionally include a CRC of the file contents, although
+            libarchive does not currently verify this CRC.
+
+     Cpio first appeared in PWB/UNIX 1.0, which was released within AT&T in
+     1977.  PWB/UNIX 1.0 formed the basis of System III Unix, released outside
+     of AT&T in 1981.  This makes cpio older than tar, although cpio was not
+     included in Version 7 AT&T Unix.  As a result, the tar command became
+     much better known in universities and research groups that used Version
+     7.  The combination of the find and cpio utilities provided very precise
+     control over file selection.  Unfortunately, the format has many limita-
+     tions that make it unsuitable for widespread use. Only the POSIX format
+     permits files over 4GB, and its 18-bit limit for most other fields makes
+     it unsuitable for modern systems. In addition, cpio formats only store
+     numeric UID/GID values (not usernames and group names), which can make it
+     very difficult to correctly transfer archives across systems with dissim-
+     ilar user numbering.
+
+   Shar Formats
+     A ``shell archive'' is a shell script that, when executed on a POSIX-com-
+     pliant system, will recreate a collection of file system objects. The
+     libarchive library can write two different kinds of shar archives:
+
+     shar    The traditional shar format uses a limited set of POSIX commands,
+            including echo(1), mkdir(1), and sed(1).  It is suitable for
+            portably archiving small collections of plain text files.  How-
+            ever, it is not generally well-suited for large archives (many
+            implementations of sh(1) have limits on the size of a script) nor
+            should it be used with non-text files.
+
+     shardump
+            This format is similar to shar but encodes files using
+            uuencode(1) so that the result will be a plain text file regard-
+            less of the file contents.  It also includes additional shell
+            commands that attempt to reproduce as many file attributes as
+            possible, including owner, mode, and flags.  The additional com-
+            mands used to restore file attributes make shardump archives less
+            portable than plain shar archives.
+
+   ISO9660 format
+     Libarchive can read and extract from files containing ISO9660-compliant
+     CDROM images.  In many cases, this can remove the need to burn a physical
+     CDROM just in order to read the files contained in an ISO9660 image.  It
+     also avoids security and complexity issues that come with virtual mounts
+     and loopback devices.  Libarchive supports the most common Rockridge
+     extensions and has partial support for Joliet extensions. If both exten-
+     sions are present, the Joliet extensions will be used and the Rockridge
+     extensions will be ignored.  In particular, this can create problems with
+     hardlinks and symlinks, which are supported by Rockridge but not by
+     Joliet.
+
+   Zip format
+     Libarchive can read and write zip format archives that have uncompressed
+     entries and entries compressed with the ``deflate'' algorithm.  Older zip
+     compression algorithms are not supported. It can extract jar archives,
+     archives that use Zip64 extensions and many self-extracting zip archives.
+     Libarchive reads Zip archives as they are being streamed, which allows it
+     to read archives of arbitrary size.  It currently does not use the cen-
+     tral directory; this limits libarchive's ability to support some self-
+     extracting archives and ones that have been modified in certain ways.
+
+   Archive (library) file format
+     The Unix archive format (commonly created by the ar(1) archiver) is a
+     general-purpose format which is used almost exclusively for object files
+     to be read by the link editor ld(1).  The ar format has never been stan-
+     dardised. There are two common variants: the GNU format derived from
+     SVR4, and the BSD format, which first appeared in 4.4BSD. The two differ
+     primarily in their handling of filenames longer than 15 characters: the
+     GNU/SVR4 variant writes a filename table at the beginning of the archive;
+     the BSD format stores each long filename in an extension area adjacent to
+     the entry.  Libarchive can read both extensions, including archives that
+     may include both types of long filenames. Programs using libarchive can
+     write GNU/SVR4 format if they provide a filename table to be written into
+     the archive before any of the entries.  Any entries whose names are not
+     in the filename table will be written using BSD-style long filenames.
+     This can cause problems for programs such as GNU ld that do not support
+     the BSD-style long filenames.
+
+   mtree
+     Libarchive can read and write files in mtree(5) format.  This format is
+     not a true archive format, but rather a textual description of a file
+     hierarchy in which each line specifies the name of a file and provides
+     specific metadata about that file.  Libarchive can read all of the key-
+     words supported by both the NetBSD and FreeBSD versions of mtree(1),
+     although many of the keywords cannot currently be stored in an
+     archive_entry object.  When writing, libarchive supports use of the
+     archive_write_set_options(3) interface to specify which keywords should
+     be included in the output.  If libarchive was compiled with access to
+     suitable cryptographic libraries (such as the OpenSSL libraries), it can
+     compute hash entries such as sha512 or md5 from file data being written
+     to the mtree writer.
+
+     When reading an mtree file, libarchive will locate the corresponding
+     files on disk using the contents keyword if present or the regular file-
+     name.  If it can locate and open the file on disk, it will use that to
+     fill in any metadata that is missing from the mtree file and will read
+     the file contents and return those to the program using libarchive.  If
+     it cannot locate and open the file on disk, libarchive will return an
+     error for any attempt to read the entry body.

+
+NAME
+     libarchive -- functions for reading and writing streaming archives
+
+LIBRARY
+     Streaming Archive Library (libarchive, -larchive)
+
+OVERVIEW
+     The libarchive library provides a flexible interface for reading and
+     writing streaming archive files such as tar and cpio.  The library is
+     inherently stream-oriented; readers serially iterate through the archive,
+     writers serially add things to the archive.  In particular, note that
+     there is no built-in support for random access nor for in-place modifica-
+     tion.
+
+     When reading an archive, the library automatically detects the format and
+     the compression.  The library currently has read support for:
+     o  old-style tar archives,
+     o  most variants of the POSIX ``ustar'' format,
+     o  the POSIX ``pax interchange'' format,
+     o  GNU-format tar archives,
+     o  most common cpio archive formats,
+     o  ISO9660 CD images (with or without RockRidge extensions),
+     o  Zip archives.
+     The library automatically detects archives compressed with gzip(1),
+     bzip2(1), or compress(1) and decompresses them transparently.
+
+     When writing an archive, you can specify the compression to be used and
+     the format to use.  The library can write
+     o  POSIX-standard ``ustar'' archives,
+     o  POSIX ``pax interchange format'' archives,
+     o  POSIX octet-oriented cpio archives,
+     o  two different variants of shar archives.
+     Pax interchange format is an extension of the tar archive format that
+     eliminates essentially all of the limitations of historic tar formats in
+     a standard fashion that is supported by POSIX-compliant pax(1) implemen-
+     tations on many systems as well as several newer implementations of
+     tar(1).  Note that the default write format will suppress the pax
+     extended attributes for most entries; explicitly requesting pax format
+     will enable those attributes for all entries.
+
+     The read and write APIs are accessed through the archive_read_XXX() func-
+     tions and the archive_write_XXX() functions, respectively, and either can
+     be used independently of the other.
+
+     The rest of this manual page provides an overview of the library opera-
+     tion.  More detailed information can be found in the individual manual
+     pages for each API or utility function.
+
+READING AN ARCHIVE
+     To read an archive, you must first obtain an initialized struct archive
+     object from archive_read_new().  You can then modify this object for the
+     desired operations with the various archive_read_set_XXX() and
+     archive_read_support_XXX() functions.  In particular, you will need to
+     invoke appropriate archive_read_support_XXX() functions to enable the
+     corresponding compression and format support.  Note that these latter
+     functions perform two distinct operations: they cause the corresponding
+     support code to be linked into your program, and they enable the corre-
+     sponding auto-detect code.  Unless you have specific constraints, you
+     will generally want to invoke archive_read_support_compression_all() and
+     archive_read_support_format_all() to enable auto-detect for all formats
+     and compression types currently supported by the library.
+
+     Once you have prepared the struct archive object, you call
+     archive_read_open() to actually open the archive and prepare it for read-
+     ing.  There are several variants of this function; the most basic expects
+     you to provide pointers to several functions that can provide blocks of
+     bytes from the archive.  There are convenience forms that allow you to
+     specify a filename, file descriptor, FILE * object, or a block of memory
+     from which to read the archive data.  Note that the core library makes no
+     assumptions about the size of the blocks read; callback functions are
+     free to read whatever block size is most appropriate for the medium.
+
+     Each archive entry consists of a header followed by a certain amount of
+     data.  You can obtain the next header with archive_read_next_header(),
+     which returns a pointer to an struct archive_entry structure with infor-
+     mation about the current archive element. If the entry is a regular
+     file, then the header will be followed by the file data.  You can use
+     archive_read_data() (which works much like the read(2) system call) to
+     read this data from the archive.  You may prefer to use the higher-level
+     archive_read_data_skip(), which reads and discards the data for this
+     entry, archive_read_data_to_buffer(), which reads the data into an in-
+     memory buffer, archive_read_data_to_file(), which copies the data to the
+     provided file descriptor, or archive_read_extract(), which recreates the
+     specified entry on disk and copies data from the archive. In particular,
+     note that archive_read_extract() uses the struct archive_entry structure
+     that you provide it, which may differ from the entry just read from the
+     archive.  In particular, many applications will want to override the
+     pathname, file permissions, or ownership.
+
+     Once you have finished reading data from the archive, you should call
+     archive_read_close() to close the archive, then call
+     archive_read_finish() to release all resources, including all memory
+     allocated by the library.
+
+     The archive_read(3) manual page provides more detailed calling informa-
+     tion for this API.
+
+WRITING AN ARCHIVE
+     You use a similar process to write an archive.  The archive_write_new()
+     function creates an archive object useful for writing, the various
+     archive_write_set_XXX() functions are used to set parameters for writing
+     the archive, and archive_write_open() completes the setup and opens the
+     archive for writing.
+
+     Individual archive entries are written in a three-step process: You first
+     initialize a struct archive_entry structure with information about the
+     new entry.  At a minimum, you should set the pathname of the entry and
+     provide a struct stat with a valid st_mode field, which specifies the
+     type of object and st_size field, which specifies the size of the data
+     portion of the object.  The archive_write_header() function actually
+     writes the header data to the archive.  You can then use
+     archive_write_data() to write the actual data.
+
+     After all entries have been written, use the archive_write_finish() func-
+     tion to release all resources.
+
+     The archive_write(3) manual page provides more detailed calling informa-
+     tion for this API.
+
+DESCRIPTION
+     Detailed descriptions of each function are provided by the corresponding
+     manual pages.
+
+     All of the functions utilize an opaque struct archive datatype that pro-
+     vides access to the archive contents.
+
+     The struct archive_entry structure contains a complete description of a
+     single archive entry.  It uses an opaque interface that is fully docu-
+     mented in archive_entry(3).
+
+     Users familiar with historic formats should be aware that the newer vari-
+     ants have eliminated most restrictions on the length of textual fields.
+     Clients should not assume that filenames, link names, user names, or
+     group names are limited in length.  In particular, pax interchange format
+     can easily accommodate pathnames in arbitrary character sets that exceed
+     PATH_MAX.
+
+RETURN VALUES
+     Most functions return zero on success, non-zero on error. The return
+     value indicates the general severity of the error, ranging from
+     ARCHIVE_WARN, which indicates a minor problem that should probably be
+     reported to the user, to ARCHIVE_FATAL, which indicates a serious problem
+     that will prevent any further operations on this archive. On error, the
+     archive_errno() function can be used to retrieve a numeric error code
+     (see errno(2)).  The archive_error_string() returns a textual error mes-
+     sage suitable for display.
+
+     archive_read_new() and archive_write_new() return pointers to an allo-
+     cated and initialized struct archive object.
+
+     archive_read_data() and archive_write_data() return a count of the number
+     of bytes actually read or written.  A value of zero indicates the end of
+     the data for this entry.  A negative value indicates an error, in which
+     case the archive_errno() and archive_error_string() functions can be used
+     to obtain more information.
+
+ENVIRONMENT
+     There are character set conversions within the archive_entry(3) functions
+     that are impacted by the currently-selected locale.

+
+NAME
+     libarchive_internals -- description of libarchive internal interfaces
+
+OVERVIEW
+     The libarchive library provides a flexible interface for reading and
+     writing streaming archive files such as tar and cpio.  Internally, it
+     follows a modular layered design that should make it easy to add new ar-
+     chive and compression formats.
+
+GENERAL ARCHITECTURE
+     Externally, libarchive exposes most operations through an opaque, object-
+     style interface.  The archive_entry(1) objects store information about a
+     single filesystem object. The rest of the library provides facilities to
+     write archive_entry(1) objects to archive files, read them from archive
+     files, and write them to disk.  (There are plans to add a facility to
+     read archive_entry(1) objects from disk as well.)
+
+     The read and write APIs each have four layers: a public API layer, a for-
+     mat layer that understands the archive file format, a compression layer,
+     and an I/O layer. The I/O layer is completely exposed to clients who can
+     replace it entirely with their own functions.
+
+     In order to provide as much consistency as possible for clients, some
+     public functions are virtualized. Eventually, it should be possible for
+     clients to open an archive or disk writer, and then use a single set of
+     code to select and write entries, regardless of the target.
+
+READ ARCHITECTURE
+     From the outside, clients use the archive_read(3) API to manipulate an
+     archive object to read entries and bodies from an archive stream. Inter-
+     nally, the archive object is cast to an archive_read object, which holds
+     all read-specific data.  The API has four layers: The lowest layer is the
+     I/O layer.  This layer can be overridden by clients, but most clients use
+     the packaged I/O callbacks provided, for example, by
+     archive_read_open_memory(3), and archive_read_open_fd(3). The compres-
+     sion layer calls the I/O layer to read bytes and decompresses them for
+     the format layer. The format layer unpacks a stream of uncompressed
+     bytes and creates archive_entry objects from the incoming data.  The API
+     layer tracks overall state (for example, it prevents clients from reading
+     data before reading a header) and invokes the format and compression
+     layer operations through registered function pointers.  In particular,
+     the API layer drives the format-detection process: When opening the ar-
+     chive, it reads an initial block of data and offers it to each registered
+     compression handler.  The one with the highest bid is initialized with
+     the first block.  Similarly, the format handlers are polled to see which
+     handler is the best for each archive.  (Prior to 2.4.0, the format bid-
+     ders were invoked for each entry, but this design hindered error recov-
+     ery.)
+
+   I/O Layer and Client Callbacks
+     The read API goes to some lengths to be nice to clients.  As a result,
+     there are few restrictions on the behavior of the client callbacks.
+
+     The client read callback is expected to provide a block of data on each
+     call.  A zero-length return does indicate end of file, but otherwise
+     blocks may be as small as one byte or as large as the entire file.  In
+     particular, blocks may be of different sizes.
+
+     The client skip callback returns the number of bytes actually skipped,
+     which may be much smaller than the skip requested.  The only requirement
+     is that the skip not be larger.  In particular, clients are allowed to
+     return zero for any skip that they don't want to handle.  The skip call-
+     back must never be invoked with a negative value.
+
+     Keep in mind that not all clients are reading from disk: clients reading
+     from networks may provide different-sized blocks on every request and
+     cannot skip at all; advanced clients may use mmap(2) to read the entire
+     file into memory at once and return the entire file to libarchive as a
+     single block; other clients may begin asynchronous I/O operations for the
+     next block on each request.
+
+   Decompresssion Layer
+     The decompression layer not only handles decompression, it also buffers
+     data so that the format handlers see a much nicer I/O model.  The decom-
+     pression API is a two stage peek/consume model.  A read_ahead request
+     specifies a minimum read amount; the decompression layer must provide a
+     pointer to at least that much data.  If more data is immediately avail-
+     able, it should return more: the format layer handles bulk data reads by
+     asking for a minimum of one byte and then copying as much data as is
+     available.
+
+     A subsequent call to the consume() function advances the read pointer.
+     Note that data returned from a read_ahead() call is guaranteed to remain
+     in place until the next call to read_ahead().  Intervening calls to
+     consume() should not cause the data to move.
+
+     Skip requests must always be handled exactly.  Decompression handlers
+     that cannot seek forward should not register a skip handler; the API
+     layer fills in a generic skip handler that reads and discards data.
+
+     A decompression handler has a specific lifecycle:
+     Registration/Configuration
+            When the client invokes the public support function, the decom-
+            pression handler invokes the internal
+            __archive_read_register_compression() function to provide bid and
+            initialization functions.  This function returns NULL on error or
+            else a pointer to a struct decompressor_t.  This structure con-
+            tains a void * config slot that can be used for storing any cus-
+            tomization information.
+     Bid     The bid function is invoked with a pointer and size of a block of
+            data.  The decompressor can access its config data through the
+            decompressor element of the archive_read object.  The bid func-
+            tion is otherwise stateless.  In particular, it must not perform
+            any I/O operations.
+
+            The value returned by the bid function indicates its suitability
+            for handling this data stream.  A bid of zero will ensure that
+            this decompressor is never invoked.  Return zero if magic number
+            checks fail.  Otherwise, your initial implementation should
+            return the number of bits actually checked.  For example, if you
+            verify two full bytes and three bits of another byte, bid 19.
+            Note that the initial block may be very short; be careful to only
+            inspect the data you are given.  (The current decompressors
+            require two bytes for correct bidding.)
+     Initialize
+            The winning bidder will have its init function called.  This
+            function should initialize the remaining slots of the struct
+            decompressor_t object pointed to by the decompressor element of
+            the archive_read object.  In particular, it should allocate any
+            working data it needs in the data slot of that structure.  The
+            init function is called with the block of data that was used for
+            tasting.  At this point, the decompressor is responsible for all
+            I/O requests to the client callbacks.  The decompressor is free
+            to read more data as and when necessary.
+     Satisfy I/O requests
+            The format handler will invoke the read_ahead, consume, and skip
+            functions as needed.
+     Finish  The finish method is called only once when the archive is closed.
+            It should release anything stored in the data and config slots of
+            the decompressor object.  It should not invoke the client close
+            callback.
+
+   Format Layer
+     The read formats have a similar lifecycle to the decompression handlers:
+     Registration
+            Allocate your private data and initialize your pointers.
+     Bid     Formats bid by invoking the read_ahead() decompression method but
+            not calling the consume() method.  This allows each bidder to
+            look ahead in the input stream.  Bidders should not look further
+            ahead than necessary, as long look aheads put pressure on the
+            decompression layer to buffer lots of data.  Most formats only
+            require a few hundred bytes of look ahead; look aheads of a few
+            kilobytes are reasonable.  (The ISO9660 reader sometimes looks
+            ahead by 48k, which should be considered an upper limit.)
+     Read header
+            The header read is usually the most complex part of any format.
+            There are a few strategies worth mentioning: For formats such as
+            tar or cpio, reading and parsing the header is straightforward
+            since headers alternate with data.  For formats that store all
+            header data at the beginning of the file, the first header read
+            request may have to read all headers into memory and store that
+            data, sorted by the location of the file data.  Subsequent header
+            read requests will skip forward to the beginning of the file data
+            and return the corresponding header.
+     Read Data
+            The read data interface supports sparse files; this requires that
+            each call return a block of data specifying the file offset and
+            size.  This may require you to carefully track the location so
+            that you can return accurate file offsets for each read.  Remem-
+            ber that the decompressor will return as much data as it has.
+            Generally, you will want to request one byte, examine the return
+            value to see how much data is available, and possibly trim that
+            to the amount you can use.  You should invoke consume for each
+            block just before you return it.
+     Skip All Data
+            The skip data call should skip over all file data and trailing
+            padding.  This is called automatically by the API layer just
+            before each header read.  It is also called in response to the
+            client calling the public data_skip() function.
+     Cleanup
+            On cleanup, the format should release all of its allocated mem-
+            ory.

+     XXX to do XXX
+
+WRITE ARCHITECTURE
+     The write API has a similar set of four layers: an API layer, a format
+     layer, a compression layer, and an I/O layer.  The registration here is
+     much simpler because only one format and one compression can be regis-
+     tered at a time.

+
+WRITE_DISK ARCHITECTURE
+     The write_disk API is intended to look just like the write API to
+     clients.  Since it does not handle multiple formats or compression, it is
+     not layered internally.
+
+GENERAL SERVICES
+     The archive_read, archive_write, and archive_write_disk objects all con-
+     tain an initial archive object which provides common support for a set of
+     standard services.  (Recall that ANSI/ISO C90 guarantees that you can
+     cast freely between a pointer to a structure and a pointer to the first
+     element of that structure.)  The archive object has a magic value that
+     indicates which API this object is associated with, slots for storing
+     error information, and function pointers for virtualized API functions.
+
+MISCELLANEOUS NOTES
+     Connecting existing archiving libraries into libarchive is generally
+     quite difficult.  In particular, many existing libraries strongly assume
+     that you are reading from a file; they seek forwards and backwards as
+     necessary to locate various pieces of information.  In contrast,
+     libarchive never seeks backwards in its input, which sometimes requires
+     very different approaches.
+
+     For example, libarchive's ISO9660 support operates very differently from
+     most ISO9660 readers.  The libarchive support utilizes a work-queue
+     design that keeps a list of known entries sorted by their location in the
+     input.  Whenever libarchive's ISO9660 implementation is asked for the
+     next header, checks this list to find the next item on the disk.  Direc-
+     tories are parsed when they are encountered and new items are added to
+     the list. This design relies heavily on the ISO9660 image being opti-
+     mized so that directories always occur earlier on the disk than the files
+     they describe.
+
+     Depending on the specific format, such approaches may not be possible.
+     The ZIP format specification, for example, allows archivers to store key
+     information only at the end of the file.  In theory, it is possible to
+     create ZIP archives that cannot be read without seeking.  Fortunately,
+     such archives are very rare, and libarchive can read most ZIP archives,
+     though it cannot always extract as much information as a dedicated ZIP
+     program.

+NAME
+     mtree -- format of mtree dir hierarchy files
+
+DESCRIPTION
+     The mtree format is a textual format that describes a collection of
+     filesystem objects.  Such files are typically used to create or verify
+     directory hierarchies.
+
+   General Format
+     An mtree file consists of a series of lines, each providing information
+     about a single filesystem object. Leading whitespace is always ignored.
+
+     When encoding file or pathnames, any backslash character or character
+     outside of the 95 printable ASCII characters must be encoded as a a back-
+     slash followed by three octal digits.  When reading mtree files, any
+     appearance of a backslash followed by three octal digits should be con-
+     verted into the corresponding character.
+
+     Each line is interpreted independently as one of the following types:
+
+     Signature  The first line of any mtree file must begin with ``#mtree''.
+                If a file contains any full path entries, the first line
+                should begin with ``#mtree v2.0'', otherwise, the first line
+                should begin with ``#mtree v1.0''.
+
+     Blank      Blank lines are ignored.
+
+     Comment    Lines beginning with # are ignored.
+
+     Special    Lines beginning with / are special commands that influence
+                the interpretation of later lines.
+
+     Relative   If the first whitespace-delimited word has no / characters,
+                it is the name of a file in the current directory.  Any rela-
+                tive entry that describes a directory changes the current
+                directory.
+
+     dot-dot    As a special case, a relative entry with the filename ..
+                changes the current directory to the parent directory.
+                Options on dot-dot entries are always ignored.
+
+     Full       If the first whitespace-delimited word has a / character
+                after the first character, it is the pathname of a file rela-
+                tive to the starting directory.  There can be multiple full
+                entries describing the same file.
+
+     Some tools that process mtree files may require that multiple lines
+     describing the same file occur consecutively.  It is not permitted for
+     the same file to be mentioned using both a relative and a full file spec-
+     ification.
+
+   Special commands
+     Two special commands are currently defined:
+
+     /set       This command defines default values for one or more keywords.
+                It is followed on the same line by one or more whitespace-
+                separated keyword definitions.  These definitions apply to
+                all following files that do not specify a value for that key-
+                word.
+
+     /unset     This command removes any default value set by a previous /set
+                command.  It is followed on the same line by one or more key-
+                words separated by whitespace.
+
+   Keywords
+     After the filename, a full or relative entry consists of zero or more
+     whitespace-separated keyword definitions. Each such definition consists
+     of a key from the following list immediately followed by an '=' sign and
+     a value.  Software programs reading mtree files should warn about unrec-
+     ognized keywords.
+
+     Currently supported keywords are as follows:
+
+     cksum      The checksum of the file using the default algorithm speci-
+                fied by the cksum(1) utility.
+
+     contents   The full pathname of a file that holds the contents of this
+                file.
+
+     flags      The file flags as a symbolic name.  See chflags(1) for infor-
+                mation on these names.  If no flags are to be set the string
+                ``none'' may be used to override the current default.
+
+     gid        The file group as a numeric value.
+
+     gname      The file group as a symbolic name.
+
+     ignore     Ignore any file hierarchy below this file.
+
+     link       The target of the symbolic link when type=link.
+
+     md5        The MD5 message digest of the file.
+
+     md5digest  A synonym for md5.
+
+     mode       The current file's permissions as a numeric (octal) or sym-
+                bolic value.
+
+     nlink      The number of hard links the file is expected to have.
+
+     nochange   Make sure this file or directory exists but otherwise ignore
+                all attributes.
+
+     ripemd160digest
+                The RIPEMD160 message digest of the file.
+
+     rmd160     A synonym for ripemd160digest.
+
+     rmd160digest
+                A synonym for ripemd160digest.
+
+     sha1       The FIPS 160-1 (``SHA-1'') message digest of the file.
+
+     sha1digest  A synonym for sha1.
+
+     sha256     The FIPS 180-2 (``SHA-256'') message digest of the file.
+
+     sha256digest
+                A synonym for sha256.
+
+     size       The size, in bytes, of the file.
+
+     time       The last modification time of the file.
+
+     type       The type of the file; may be set to any one of the following:
+
+                block       block special device
+                char        character special device
+                dir         directory
+                fifo        fifo
+                file        regular file
+                link        symbolic link
+                socket      socket
+
+     uid        The file owner as a numeric value.

+BUGS
+     The FreeBSD implementation of mtree does not currently support the mtree
+     2.0 format.  The requirement for a ``#mtree'' signature line is new and
+     not yet widely implemented.
+
+HISTORY
+     The mtree utility appeared in 4.3BSD-Reno.  The MD5 digest capability was
+     added in FreeBSD 2.1, in response to the widespread use of programs which

+NAME
+     tar -- format of tape archive files
+
+DESCRIPTION
+     The tar archive format collects any number of files, directories, and
+     other file system objects (symbolic links, device nodes, etc.) into a
+     single stream of bytes.  The format was originally designed to be used
+     with tape drives that operate with fixed-size blocks, but is widely used
+     as a general packaging mechanism.
+
+   General Format
+     A tar archive consists of a series of 512-byte records.  Each file system
+     object requires a header record which stores basic metadata (pathname,
+     owner, permissions, etc.) and zero or more records containing any file
+     data.  The end of the archive is indicated by two records consisting
+     entirely of zero bytes.
+
+     For compatibility with tape drives that use fixed block sizes, programs
+     that read or write tar files always read or write a fixed number of
+     records with each I/O operation.  These ``blocks'' are always a multiple
+     of the record size.  The maximum block size supported by early implemen-
+     tations was 10240 bytes or 20 records.  This is still the default for
+     most implementations although block sizes of 1MiB (2048 records) or
+     larger are commonly used with modern high-speed tape drives.  (Note: the
+     terms ``block'' and ``record'' here are not entirely standard; this docu-
+     ment follows the convention established by John Gilmore in documenting
+     pdtar.)
+
+   Old-Style Archive Format
+     The original tar archive format has been extended many times to include
+     additional information that various implementors found necessary. This
+     section describes the variant implemented by the tar command included in
+     Version 7 AT&T UNIX, which seems to be the earliest widely-used version
+     of the tar program.
+
+     The header record for an old-style tar archive consists of the following:
+
+          struct header_old_tar {
+                  char name[100];
+                  char mode[8];
+                  char uid[8];
+                  char gid[8];
+                  char size[12];
+                  char mtime[12];
+                  char checksum[8];
+                  char linkflag[1];
+                  char linkname[100];
+                  char pad[255];
+          };
+     All unused bytes in the header record are filled with nulls.
+
+     name    Pathname, stored as a null-terminated string.  Early tar imple-
+            mentations only stored regular files (including hardlinks to
+            those files).  One common early convention used a trailing "/"
+            character to indicate a directory name, allowing directory per-
+            missions and owner information to be archived and restored.
+
+     mode    File mode, stored as an octal number in ASCII.
+
+     uid, gid
+            User id and group id of owner, as octal numbers in ASCII.
+
+     size    Size of file, as octal number in ASCII.  For regular files only,
+            this indicates the amount of data that follows the header.  In
+            particular, this field was ignored by early tar implementations
+            when extracting hardlinks.  Modern writers should always store a
+            zero length for hardlink entries.
+
+     mtime   Modification time of file, as an octal number in ASCII.  This
+            indicates the number of seconds since the start of the epoch,
+            00:00:00 UTC January 1, 1970.  Note that negative values should
+            be avoided here, as they are handled inconsistently.
+
+     checksum
+            Header checksum, stored as an octal number in ASCII.  To compute
+            the checksum, set the checksum field to all spaces, then sum all
+            bytes in the header using unsigned arithmetic.  This field should
+            be stored as six octal digits followed by a null and a space
+            character.  Note that many early implementations of tar used
+            signed arithmetic for the checksum field, which can cause inter-
+            operability problems when transferring archives between systems.
+            Modern robust readers compute the checksum both ways and accept
+            the header if either computation matches.
+
+     linkflag, linkname
+            In order to preserve hardlinks and conserve tape, a file with
+            multiple links is only written to the archive the first time it
+            is encountered.  The next time it is encountered, the linkflag is
+            set to an ASCII `1' and the linkname field holds the first name
+            under which this file appears.  (Note that regular files have a
+            null value in the linkflag field.)
+
+     Early tar implementations varied in how they terminated these fields.
+     The tar command in Version 7 AT&T UNIX used the following conventions
+     (this is also documented in early BSD manpages): the pathname must be
+     null-terminated; the mode, uid, and gid fields must end in a space and a
+     null byte; the size and mtime fields must end in a space; the checksum is
+     terminated by a null and a space. Early implementations filled the
+     numeric fields with leading spaces.  This seems to have been common prac-
+     tice until the IEEE Std 1003.1-1988 (``POSIX.1'') standard was released.
+     For best portability, modern implementations should fill the numeric
+     fields with leading zeros.
+
+   Pre-POSIX Archives
+     An early draft of IEEE Std 1003.1-1988 (``POSIX.1'') served as the basis
+     for John Gilmore's pdtar program and many system implementations from the
+     late 1980s and early 1990s.  These archives generally follow the POSIX
+     ustar format described below with the following variations:
+     o      The magic value is ``ustar '' (note the following space).  The
+            version field contains a space character followed by a null.
+     o      The numeric fields are generally filled with leading spaces (not
+            leading zeros as recommended in the final standard).
+     o      The prefix field is often not used, limiting pathnames to the 100
+            characters of old-style archives.
+
+   POSIX ustar Archives
+     IEEE Std 1003.1-1988 (``POSIX.1'') defined a standard tar file format to
+     be read and written by compliant implementations of tar(1).  This format
+     is often called the ``ustar'' format, after the magic value used in the
+     header.  (The name is an acronym for ``Unix Standard TAR''.)  It extends
+     the historic format with new fields:
+
+          struct header_posix_ustar {
+                  char name[100];
+                  char mode[8];
+                  char uid[8];
+                  char gid[8];
+                  char size[12];
+                  char mtime[12];
+                  char checksum[8];
+                  char typeflag[1];
+                  char linkname[100];
+                  char magic[6];
+                  char version[2];
+                  char uname[32];
+                  char gname[32];
+                  char devmajor[8];
+                  char devminor[8];
+                  char prefix[155];
+                  char pad[12];
+          };
+
+     typeflag
+            Type of entry.  POSIX extended the earlier linkflag field with
+            several new type values:
+            ``0''   Regular file.  NUL should be treated as a synonym, for
+                    compatibility purposes.
+            ``1''   Hard link.
+            ``2''   Symbolic link.
+            ``3''   Character device node.
+            ``4''   Block device node.
+            ``5''   Directory.
+            ``6''   FIFO node.
+            ``7''   Reserved.
+            Other   A POSIX-compliant implementation must treat any unrecog-
+                    nized typeflag value as a regular file.  In particular,
+                    writers should ensure that all entries have a valid file-
+                    name so that they can be restored by readers that do not
+                    support the corresponding extension.  Uppercase letters
+                    "A" through "Z" are reserved for custom extensions.  Note
+                    that sockets and whiteout entries are not archivable.
+            It is worth noting that the size field, in particular, has dif-
+            ferent meanings depending on the type.  For regular files, of
+            course, it indicates the amount of data following the header.
+            For directories, it may be used to indicate the total size of all
+            files in the directory, for use by operating systems that pre-
+            allocate directory space.  For all other types, it should be set
+            to zero by writers and ignored by readers.
+
+     magic   Contains the magic value ``ustar'' followed by a NUL byte to
+            indicate that this is a POSIX standard archive.  Full compliance
+            requires the uname and gname fields be properly set.
+
+     version
+            Version.  This should be ``00'' (two copies of the ASCII digit
+            zero) for POSIX standard archives.
+
+     uname, gname
+            User and group names, as null-terminated ASCII strings.  These
+            should be used in preference to the uid/gid values when they are
+            set and the corresponding names exist on the system.
+
+     devmajor, devminor
+            Major and minor numbers for character device or block device
+            entry.
+
+     name, prefix
+            If the pathname is too long to fit in the 100 bytes provided by
+            the standard format, it can be split at any / character with the
+            first portion going into the prefix field.  If the prefix field
+            is not empty, the reader will prepend the prefix value and a /
+            character to the regular name field to obtain the full pathname.
+            The standard does not require a trailing / character on directory
+            names, though most implementations still include this for compat-
+            ibility reasons.
+
+     Note that all unused bytes must be set to NUL.
+
+     Field termination is specified slightly differently by POSIX than by pre-
+     vious implementations.  The magic, uname, and gname fields must have a
+     trailing NUL.  The pathname, linkname, and prefix fields must have a
+     trailing NUL unless they fill the entire field.  (In particular, it is
+     possible to store a 256-character pathname if it happens to have a / as
+     the 156th character.)  POSIX requires numeric fields to be zero-padded in
+     the front, and requires them to be terminated with either space or NUL
+     characters.
+
+     Currently, most tar implementations comply with the ustar format, occa-
+     sionally extending it by adding new fields to the blank area at the end
+     of the header record.
+
+   Pax Interchange Format
+     There are many attributes that cannot be portably stored in a POSIX ustar
+     archive.  IEEE Std 1003.1-2001 (``POSIX.1'') defined a ``pax interchange
+     format'' that uses two new types of entries to hold text-formatted meta-
+     data that applies to following entries.  Note that a pax interchange for-
+     mat archive is a ustar archive in every respect.  The new data is stored
+     in ustar-compatible archive entries that use the ``x'' or ``g'' typeflag.
+     In particular, older implementations that do not fully support these
+     extensions will extract the metadata into regular files, where the meta-
+     data can be examined as necessary.
+
+     An entry in a pax interchange format archive consists of one or two stan-
+     dard ustar entries, each with its own header and data.  The first
+     optional entry stores the extended attributes for the following entry.
+     This optional first entry has an "x" typeflag and a size field that indi-
+     cates the total size of the extended attributes.  The extended attributes
+     themselves are stored as a series of text-format lines encoded in the
+     portable UTF-8 encoding.  Each line consists of a decimal number, a
+     space, a key string, an equals sign, a value string, and a new line.  The
+     decimal number indicates the length of the entire line, including the
+     initial length field and the trailing newline.  An example of such a
+     field is:
+          25 ctime=1084839148.1212\n
+     Keys in all lowercase are standard keys.  Vendors can add their own keys
+     by prefixing them with an all uppercase vendor name and a period. Note
+     that, unlike the historic header, numeric values are stored using deci-
+     mal, not octal.  A description of some common keys follows:
+
+     atime, ctime, mtime
+            File access, inode change, and modification times.  These fields
+            can be negative or include a decimal point and a fractional
+            value.
+
+     uname, uid, gname, gid
+            User name, group name, and numeric UID and GID values.  The user
+            name and group name stored here are encoded in UTF8 and can thus
+            include non-ASCII characters.  The UID and GID fields can be of
+            arbitrary length.
+
+     linkpath
+            The full path of the linked-to file.  Note that this is encoded
+            in UTF8 and can thus include non-ASCII characters.
+
+     path    The full pathname of the entry.  Note that this is encoded in
+            UTF8 and can thus include non-ASCII characters.
+
+     realtime.*, security.*
+            These keys are reserved and may be used for future standardiza-
+            tion.
+
+     size    The size of the file.  Note that there is no length limit on this
+            field, allowing conforming archives to store files much larger
+            than the historic 8GB limit.
+
+     SCHILY.*
+            Vendor-specific attributes used by Joerg Schilling's star imple-
+            mentation.
+
+     SCHILY.acl.access, SCHILY.acl.default
+            Stores the access and default ACLs as textual strings in a format
+            that is an extension of the format specified by POSIX.1e draft
+            17.  In particular, each user or group access specification can
+            include a fourth colon-separated field with the numeric UID or
+            GID.  This allows ACLs to be restored on systems that may not
+            have complete user or group information available (such as when
+            NIS/YP or LDAP services are temporarily unavailable).
+
+     SCHILY.devminor, SCHILY.devmajor
+            The full minor and major numbers for device nodes.
+
+     SCHILY.fflags
+            The file flags.
+
+     SCHILY.realsize
+            The full size of the file on disk.  XXX explain? XXX
+
+     SCHILY.dev, SCHILY.ino, SCHILY.nlinks
+            The device number, inode number, and link count for the entry.
+            In particular, note that a pax interchange format archive using
+            Joerg Schilling's SCHILY.* extensions can store all of the data
+            from struct stat.
+
+     LIBARCHIVE.xattr.namespace.key
+            Libarchive stores POSIX.1e-style extended attributes using keys
+            of this form.  The key value is URL-encoded: All non-ASCII char-
+            acters and the two special characters ``='' and ``%'' are encoded
+            as ``%'' followed by two uppercase hexadecimal digits.  The value
+            of this key is the extended attribute value encoded in base 64.
+            XXX Detail the base-64 format here XXX
+
+     VENDOR.*
+            XXX document other vendor-specific extensions XXX
+
+     Any values stored in an extended attribute override the corresponding
+     values in the regular tar header. Note that compliant readers should
+     ignore the regular fields when they are overridden.  This is important,
+     as existing archivers are known to store non-compliant values in the
+     standard header fields in this situation. There are no limits on length
+     for any of these fields.  In particular, numeric fields can be arbitrar-
+     ily large.  All text fields are encoded in UTF8.  Compliant writers
+     should store only portable 7-bit ASCII characters in the standard ustar
+     header and use extended attributes whenever a text value contains non-
+     ASCII characters.
+
+     In addition to the x entry described above, the pax interchange format
+     also supports a g entry.  The g entry is identical in format, but speci-
+     fies attributes that serve as defaults for all subsequent archive
+     entries.  The g entry is not widely used.
+
+     Besides the new x and g entries, the pax interchange format has a few
+     other minor variations from the earlier ustar format.  The most troubling
+     one is that hardlinks are permitted to have data following them.  This
+     allows readers to restore any hardlink to a file without having to rewind
+     the archive to find an earlier entry.  However, it creates complications
+     for robust readers, as it is no longer clear whether or not they should
+     ignore the size field for hardlink entries.
+
+   GNU Tar Archives
+     The GNU tar program started with a pre-POSIX format similar to that
+     described earlier and has extended it using several different mechanisms:
+     It added new fields to the empty space in the header (some of which was
+     later used by POSIX for conflicting purposes); it allowed the header to
+     be continued over multiple records; and it defined new entries that mod-
+     ify following entries (similar in principle to the x entry described
+     above, but each GNU special entry is single-purpose, unlike the general-
+     purpose x entry). As a result, GNU tar archives are not POSIX compati-
+     ble, although more lenient POSIX-compliant readers can successfully
+     extract most GNU tar archives.
+
+          struct header_gnu_tar {
+                  char name[100];
+                  char mode[8];
+                  char uid[8];
+                  char gid[8];
+                  char size[12];
+                  char mtime[12];
+                  char checksum[8];
+                  char typeflag[1];
+                  char linkname[100];
+                  char magic[6];
+                  char version[2];
+                  char uname[32];
+                  char gname[32];
+                  char devmajor[8];
+                  char devminor[8];
+                  char atime[12];
+                  char ctime[12];
+                  char offset[12];
+                  char longnames[4];
+                  char unused[1];
+                  struct {
+                          char offset[12];
+                          char numbytes[12];
+                  } sparse[4];
+                  char isextended[1];
+                  char realsize[12];
+                  char pad[17];
+          };
+
+     typeflag
+            GNU tar uses the following special entry types, in addition to
+            those defined by POSIX:
+
+            7       GNU tar treats type "7" records identically to type "0"
+                    records, except on one obscure RTOS where they are used
+                    to indicate the pre-allocation of a contiguous file on
+                    disk.
+
+            D       This indicates a directory entry.  Unlike the POSIX-stan-
+                    dard "5" typeflag, the header is followed by data records
+                    listing the names of files in this directory.  Each name
+                    is preceded by an ASCII "Y" if the file is stored in this
+                    archive or "N" if the file is not stored in this archive.
+                    Each name is terminated with a null, and an extra null
+                    marks the end of the name list.  The purpose of this
+                    entry is to support incremental backups; a program
+                    restoring from such an archive may wish to delete files
+                    on disk that did not exist in the directory when the ar-
+                    chive was made.
+
+                    Note that the "D" typeflag specifically violates POSIX,
+                    which requires that unrecognized typeflags be restored as
+                    normal files.  In this case, restoring the "D" entry as a
+                    file could interfere with subsequent creation of the
+                    like-named directory.
+
+            K       The data for this entry is a long linkname for the fol-
+                    lowing regular entry.
+
+            L       The data for this entry is a long pathname for the fol-
+                    lowing regular entry.
+
+            M       This is a continuation of the last file on the previous
+                    volume.  GNU multi-volume archives guarantee that each
+                    volume begins with a valid entry header.  To ensure this,
+                    a file may be split, with part stored at the end of one
+                    volume, and part stored at the beginning of the next vol-
+                    ume.  The "M" typeflag indicates that this entry contin-
+                    ues an existing file.  Such entries can only occur as the
+                    first or second entry in an archive (the latter only if
+                    the first entry is a volume label).  The size field spec-
+                    ifies the size of this entry.  The offset field at bytes
+                    369-380 specifies the offset where this file fragment
+                    begins.  The realsize field specifies the total size of
+                    the file (which must equal size plus offset).  When
+                    extracting, GNU tar checks that the header file name is
+                    the one it is expecting, that the header offset is in the
+                    correct sequence, and that the sum of offset and size is
+                    equal to realsize.
+
+            N       Type "N" records are no longer generated by GNU tar.
+                    They contained a list of files to be renamed or symlinked
+                    after extraction; this was originally used to support
+                    long names.  The contents of this record are a text
+                    description of the operations to be done, in the form
+                    ``Rename %s to %s\n'' or ``Symlink %s to %s\n''; in
+                    either case, both filenames are escaped using K&R C syn-
+                    tax.  Due to security concerns, "N" records are now gen-
+                    erally ignored when reading archives.
+
+            S       This is a ``sparse'' regular file.  Sparse files are
+                    stored as a series of fragments.  The header contains a
+                    list of fragment offset/length pairs.  If more than four
+                    such entries are required, the header is extended as nec-
+                    essary with ``extra'' header extensions (an older format
+                    that is no longer used), or ``sparse'' extensions.
+
+            V       The name field should be interpreted as a tape/volume
+                    header name.  This entry should generally be ignored on
+                    extraction.
+
+     magic   The magic field holds the five characters ``ustar'' followed by a
+            space.  Note that POSIX ustar archives have a trailing null.
+
+     version
+            The version field holds a space character followed by a null.
+            Note that POSIX ustar archives use two copies of the ASCII digit
+            ``0''.
+
+     atime, ctime
+            The time the file was last accessed and the time of last change
+            of file information, stored in octal as with mtime.
+
+     longnames
+            This field is apparently no longer used.
+
+     Sparse offset / numbytes
+            Each such structure specifies a single fragment of a sparse file.
+            The two fields store values as octal numbers.  The fragments are
+            each padded to a multiple of 512 bytes in the archive.  On
+            extraction, the list of fragments is collected from the header
+            (including any extension headers), and the data is then read and
+            written to the file at appropriate offsets.
+
+     isextended
+            If this is set to non-zero, the header will be followed by addi-
+            tional ``sparse header'' records.  Each such record contains
+            information about as many as 21 additional sparse blocks as shown
+            here:
+
+                  struct gnu_sparse_header {
+                          struct {
+                                  char offset[12];
+                                  char numbytes[12];
+                          } sparse[21];
+                          char    isextended[1];
+                          char    padding[7];
+                  };
+
+     realsize
+            A binary representation of the file's complete size, with a much
+            larger range than the POSIX file size.  In particular, with M
+            type files, the current entry is only a portion of the file.  In
+            that case, the POSIX size field will indicate the size of this
+            entry; the realsize field will indicate the total size of the
+            file.
+
+   GNU tar pax archives
+     GNU tar 1.14 (XXX check this XXX) and later will write pax interchange
+     format archives when you specify the --posix flag.  This format uses cus-
+     tom keywords to store sparse file information.  There have been three
+     iterations of this support, referred to as ``0.0'', ``0.1'', and ``1.0''.
+
+     GNU.sparse.numblocks, GNU.sparse.offset, GNU.sparse.numbytes,
+            GNU.sparse.size
+            The ``0.0'' format used an initial GNU.sparse.numblocks attribute
+            to indicate the number of blocks in the file, a pair of
+            GNU.sparse.offset and GNU.sparse.numbytes to indicate the offset
+            and size of each block, and a single GNU.sparse.size to indicate
+            the full size of the file.  This is not the same as the size in
+            the tar header because the latter value does not include the size
+            of any holes.  This format required that the order of attributes
+            be preserved and relied on readers accepting multiple appearances
+            of the same attribute names, which is not officially permitted by
+            the standards.
+
+     GNU.sparse.map
+            The ``0.1'' format used a single attribute that stored a comma-
+            separated list of decimal numbers.  Each pair of numbers indi-
+            cated the offset and size, respectively, of a block of data.
+            This does not work well if the archive is extracted by an
+            archiver that does not recognize this extension, since many pax
+            implementations simply discard unrecognized attributes.
+
+     GNU.sparse.major, GNU.sparse.minor, GNU.sparse.name, GNU.sparse.realsize
+            The ``1.0'' format stores the sparse block map in one or more
+            512-byte blocks prepended to the file data in the entry body.
+            The pax attributes indicate the existence of this map (via the
+            GNU.sparse.major and GNU.sparse.minor fields) and the full size
+            of the file.  The GNU.sparse.name holds the true name of the
+            file.  To avoid confusion, the name stored in the regular tar
+            header is a modified name so that extraction errors will be
+            apparent to users.
+
+   Solaris Tar
+     XXX More Details Needed XXX
+
+     Solaris tar (beginning with SunOS XXX 5.7 ?? XXX) supports an
+     ``extended'' format that is fundamentally similar to pax interchange for-
+     mat, with the following differences:
+     o      Extended attributes are stored in an entry whose type is X, not
+            x, as used by pax interchange format.  The detailed format of
+            this entry appears to be the same as detailed above for the x
+            entry.
+     o      An additional A entry is used to store an ACL for the following
+            regular entry.  The body of this entry contains a seven-digit
+            octal number followed by a zero byte, followed by the textual ACL
+            description.  The octal value is the number of ACL entries plus a
+            constant that indicates the ACL type: 01000000 for POSIX.1e ACLs
+            and 03000000 for NFSv4 ACLs.
+
+   AIX Tar
+     XXX More details needed XXX
+
+   Mac OS X Tar
+     The tar distributed with Apple's Mac OS X stores most regular files as
+     two separate entries in the tar archive.  The two entries have the same
+     name except that the first one has ``._'' added to the beginning of the
+     name.  This first entry stores the ``resource fork'' with additional
+     attributes for the file.  The Mac OS X CopyFile() API is used to separate
+     a file on disk into separate resource and data streams and to reassemble
+     those separate streams when the file is restored to disk.
+
+   Other Extensions
+     One obvious extension to increase the size of files is to eliminate the
+     terminating characters from the various numeric fields.  For example, the
+     standard only allows the size field to contain 11 octal digits, reserving
+     the twelfth byte for a trailing NUL character.  Allowing 12 octal digits
+     allows file sizes up to 64 GB.
+
+     Another extension, utilized by GNU tar, star, and other newer tar imple-
+     mentations, permits binary numbers in the standard numeric fields.  This
+     is flagged by setting the high bit of the first byte.  This permits
+     95-bit values for the length and time fields and 63-bit values for the
+     uid, gid, and device numbers.  GNU tar supports this extension for the
+     length, mtime, ctime, and atime fields.  Joerg Schilling's star program
+     supports this extension for all numeric fields.  Note that this extension
+     is largely obsoleted by the extended attribute record provided by the pax
+     interchange format.
+
+     Another early GNU extension allowed base-64 values rather than octal.
+     This extension was short-lived and is no longer supported by any imple-
+     mentation.

+
+STANDARDS
+     The tar utility is no longer a part of POSIX or the Single Unix Standard.
+     It last appeared in Version 2 of the Single UNIX Specification
+     (``SUSv2'').  It has been supplanted in subsequent standards by pax(1).
+     The ustar format is currently part of the specification for the pax(1)
+     utility.  The pax interchange file format is new with IEEE Std
+     1003.1-2001 (``POSIX.1'').
+
+HISTORY
+     A tar command appeared in Seventh Edition Unix, which was released in
+     January, 1979.  It replaced the tp program from Fourth Edition Unix which
+     in turn replaced the tap program from First Edition Unix. John Gilmore's
+     pdtar public-domain implementation (circa 1987) was highly influential
+     and formed the basis of GNU tar (circa 1988).  Joerg Shilling's star
+     archiver is another open-source (GPL) archiver (originally developed
+     circa 1985) which features complete support for pax interchange format.
+
+     This documentation was written as part of the libarchive and bsdtar
+     project by Tim Kientzle <kientzle@FreeBSD.org>.

+== DESCRIPTION ==
+These functions create and manipulate data objects that
+represent entries within an archive.
+You can think of a
+*struct archive_entry*
+as a heavy-duty version of
+*struct stat :*
+it includes everything from
+*struct stat*
+plus associated pathname, textual group and user names, etc.
+These objects are used by
+*libarchive*(3)
+to represent the metadata associated with a particular
+entry in an archive.
+=== Create and Destroy===
+There are functions to allocate, destroy, clear, and copy
+_archive_entry_
+objects:
+<dl>
+<dt>*archive_entry_clear*()</dt><dd>
+Erases the object, resetting all internal fields to the
+same state as a newly-created object.
+This is provided to allow you to quickly recycle objects
+without thrashing the heap.
+</dd><dt>*archive_entry_clone*()</dt><dd>
+A deep copy operation; all text fields are duplicated.
+</dd><dt>*archive_entry_free*()</dt><dd>
+Releases the
+*struct archive_entry*
+object.
+</dd><dt>*archive_entry_new*()</dt><dd>
+Allocate and return a blank
+*struct archive_entry*
+object.
+</dd></dl>
+=== Set and Get Functions===
+Most of the functions here set or read entries in an object.
+Such functions have one of the following forms:
+<dl>
+<dt>*archive_entry_set_XXXX*()</dt><dd>
+Stores the provided data in the object.
+In particular, for strings, the pointer is stored,
+not the referenced string.
+</dd><dt>*archive_entry_copy_XXXX*()</dt><dd>
+As above, except that the referenced data is copied
+into the object.
+</dd><dt>*archive_entry_XXXX*()</dt><dd>
+Returns the specified data.
+In the case of strings, a const-qualified pointer to
+the string is returned.
+</dd></dl>
+String data can be set or accessed as wide character strings
+or normal
+_char_
+strings.
+The functions that use wide character strings are suffixed with
+*`_`w*.
+Note that these are different representations of the same data:
+For example, if you store a narrow string and read the corresponding
+wide string, the object will transparently convert formats
+using the current locale.
+Similarly, if you store a wide string and then store a
+narrow string for the same data, the previously-set wide string will
+be discarded in favor of the new data.
+
+There are a few set/get functions that merit additional description:
+<dl>
+<dt>*archive_entry_set_link*()</dt><dd>
+This function sets the symlink field if it is already set.
+Otherwise, it sets the hardlink field.
+</dd></dl>
+=== File Flags===
+File flags are transparently converted between a bitmap
+representation and a textual format.
+For example, if you set the bitmap and ask for text, the library
+will build a canonical text format.
+However, if you set a text format and request a text format,
+you will get back the same text, even if it is ill-formed.
+If you need to canonicalize a textual flags string, you should first set the
+text form, then request the bitmap form, then use that to set the bitmap form.
+Setting the bitmap format will clear the internal text representation
+and force it to be reconstructed when you next request the text form.
+
+The bitmap format consists of two integers, one containing bits
+that should be set, the other specifying bits that should be
+cleared.
+Bits not mentioned in either bitmap will be ignored.
+Usually, the bitmap of bits to be cleared will be set to zero.
+In unusual circumstances, you can force a fully-specified set
+of file flags by setting the bitmap of flags to clear to the complement
+of the bitmap of flags to set.
+(This differs from
+*fflagstostr*(3),
+which only includes names for set bits.)
+Converting a bitmap to a textual string is a platform-specific
+operation; bits that are not meaningful on the current platform
+will be ignored.
+
+The canonical text format is a comma-separated list of flag names.
+The
+*archive_entry_copy_fflags_text*()
+and
+*archive_entry_copy_fflags_text_w*()
+functions parse the provided text and sets the internal bitmap values.
+This is a platform-specific operation; names that are not meaningful
+on the current platform will be ignored.
+The function returns a pointer to the start of the first name that was not
+recognized, or NULL if every name was recognized.
+Note that every name--including names that follow an unrecognized name--will
+be evaluated, and the bitmaps will be set to reflect every name that is
+recognized.
+(In particular, this differs from
+*strtofflags*(3),
+which stops parsing at the first unrecognized name.)
+=== ACL Handling===
+XXX This needs serious help.
+XXX
+
+An
+"Access Control List"
+(ACL) is a list of permissions that grant access to particular users or
+groups beyond what would normally be provided by standard POSIX mode bits.
+The ACL handling here addresses some deficiencies in the POSIX.1e draft 17 ACL
+specification.
+In particular, POSIX.1e draft 17 specifies several different formats, but
+none of those formats include both textual user/group names and numeric
+UIDs/GIDs.
+
+XXX explain ACL stuff XXX

+== DESCRIPTION ==
+These functions provide a complete API for reading streaming archives.
+The general process is to first create the
+*struct archive*
+object, set options, initialize the reader, iterate over the archive
+headers and associated data, then close the archive and release all
+resources.
+The following summary describes the functions in approximately the
+order they would be used:
+<dl>
+<dt>*archive_read_new*()</dt><dd>
+Allocates and initializes a
+*struct archive*
+object suitable for reading from an archive.
+</dd><dt>
+*archive_read_support_compression_bzip2*(),
+*archive_read_support_compression_compress*(),
+*archive_read_support_compression_gzip*(),
+*archive_read_support_compression_lzma*(),
+*archive_read_support_compression_none*(),
+*archive_read_support_compression_xz*()
+</dt> <dd>
+Enables auto-detection code and decompression support for the
+specified compression.
+Returns
+*ARCHIVE_OK*
+if the compression is fully supported, or
+*ARCHIVE_WARN*
+if the compression is supported only through an external program.
+Note that decompression using an external program is usually slower than
+decompression through built-in libraries.
+Note that
+"none"
+is always enabled by default.
+</dd><dt>*archive_read_support_compression_all*()</dt><dd>
+Enables all available decompression filters.
+</dd><dt>*archive_read_support_compression_program*()</dt><dd>
+Data is fed through the specified external program before being dearchived.
+Note that this disables automatic detection of the compression format,
+so it makes no sense to specify this in conjunction with any other
+decompression option.
+</dd><dt>*archive_read_support_compression_program_signature*()</dt><dd>

+The argument is a comma-separated list of individual options.
+Individual options have one of the following forms:
+<dl>
+<dt>_option=value_</dt><dd>

+The same as

+</dd><dt>*archive_read_open2*()</dt><dd>
+Freeze the settings, open the archive, and prepare for reading entries.
+This is the most generic version of this call, which accepts
+four callback functions.
+Most clients will want to use
+*archive_read_open_filename*(),

+</dd><dt>*archive_read_open_fd*()</dt><dd>
+Like
+*archive_read_open*(),

+</dd><dt>*archive_read_open_filename*()</dt><dd>
+Like
+*archive_read_open*(),
+except that it accepts a simple filename and a block size.
+A NULL filename represents standard input.
+This function is safe for use with tape drives or other blocked devices.
+</dd><dt>*archive_read_open_memory*()</dt><dd>
+Like
+*archive_read_open*(),
+except that it accepts a pointer and size of a block of
+memory containing the archive data.
+</dd><dt>*archive_read_next_header*()</dt><dd>
+Read the header for the next entry and return a pointer to
+a
+*struct archive_entry .*
+This is a convenience wrapper around
+*archive_read_next_header2*()
+that reuses an internal
+*struct archive_entry*
+object for each request.
+</dd><dt>*archive_read_next_header2*()</dt><dd>
+Read the header for the next entry and populate the provided
+*struct archive_entry .*
+</dd><dt>*archive_read_data*()</dt><dd>
+Read data associated with the header just read.
+Internally, this is a convenience function that calls
+*archive_read_data_block*()
+and fills any gaps with nulls so that callers see a single
+continuous stream of data.
+</dd><dt>*archive_read_data_block*()</dt><dd>
+Return the next available block of data for this entry.
+Unlike
+*archive_read_data*(),
+the
+*archive_read_data_block*()
+function avoids copying data and allows you to correctly handle
+sparse files, as supported by some archive formats.
+The library guarantees that offsets will increase and that blocks
+will not overlap.
+Note that the blocks returned from this function can be much larger
+than the block size read from disk, due to compression
+and internal buffer optimizations.
+</dd><dt>*archive_read_data_skip*()</dt><dd>
+A convenience function that repeatedly calls
+*archive_read_data_block*()
+to skip all of the data for this archive entry.
+</dd><dt>*archive_read_data_into_buffer*()</dt><dd>
+This function is deprecated and will be removed.
+Use
+*archive_read_data*()
+instead.
+</dd><dt>*archive_read_data_into_fd*()</dt><dd>
+A convenience function that repeatedly calls
+*archive_read_data_block*()
+to copy the entire entry to the provided file descriptor.
+</dd><dt>*archive_read_extract*(), *archive_read_extract_set_skip_file*()</dt><dd>
+A convenience function that wraps the corresponding
+*archive_write_disk*(3)
+interfaces.
+The first call to
+*archive_read_extract*()
+creates a restore object using
+*archive_write_disk_new*(3)
+and
+*archive_write_disk_set_standard_lookup*(3),
+then transparently invokes
+*archive_write_disk_set_options*(3),
+*archive_write_header*(3),
+*archive_write_data*(3),
+and
+*archive_write_finish_entry*(3)
+to create the entry on disk and copy data into it.
+The
+_flags_
+argument is passed unmodified to
+*archive_write_disk_set_options*(3).
+</dd><dt>*archive_read_extract2*()</dt><dd>
+This is another version of
+*archive_read_extract*()
+that allows you to provide your own restore object.
+In particular, this allows you to override the standard lookup functions
+using
+*archive_write_disk_set_group_lookup*(3),
+and
+*archive_write_disk_set_user_lookup*(3).
+Note that
+*archive_read_extract2*()
+does not accept a
+_flags_
+argument; you should use
+*archive_write_disk_set_options*()
+to set the restore options yourself.
+</dd><dt>*archive_read_extract_set_progress_callback*()</dt><dd>
+Sets a pointer to a user-defined callback that can be used
+for updating progress displays during extraction.
+The progress function will be invoked during the extraction of large
+regular files.
+The progress function will be invoked with the pointer provided to this call.
+Generally, the data pointed to should include a reference to the archive
+object and the archive_entry object so that various statistics
+can be retrieved for the progress display.
+</dd><dt>*archive_read_close*()</dt><dd>
+Complete the archive and invoke the close callback.
+</dd><dt>*archive_read_finish*()</dt><dd>
+Invokes
+*archive_read_close*()
+if it was not invoked manually, then release all resources.
+Note: In libarchive 1.x, this function was declared to return
+*void ,*
+which made it impossible to detect certain errors when
+*archive_read_close*()
+was invoked implicitly from this function.
+The declaration is corrected beginning with libarchive 2.0.
+</dd></dl>
+
+Note that the library determines most of the relevant information about
+the archive by inspection.
+In particular, it automatically detects
+*gzip*(1)
+or
+*bzip2*(1)
+compression and transparently performs the appropriate decompression.
+It also automatically detects the archive format.
+
+A complete description of the
+*struct archive*
+and
+*struct archive_entry*
+objects can be found in the overview manual page for
+*libarchive*(3).
+== CLIENT CALLBACKS ==
+The callback functions must match the following prototypes:
+<ul>
+<li>
+*typedef ssize_t*
+*archive_read_callback*(_struct archive `*`_, _void `*`client_data_, _const void `*``*`buffer_)
+</li><li>
+*typedef int*
+*archive_skip_callback*(_struct archive `*`_, _void `*`client_data_, _size_t request_)
+</li><li>
+*typedef int*
+*archive_open_callback*(_struct archive `*`_, _void `*`client_data_)
+</li><li>
+*typedef int*
+*archive_close_callback*(_struct archive `*`_, _void `*`client_data_)
+</li></ul>
+
+The open callback is invoked by
+*archive_open*().
+It should return
+*ARCHIVE_OK*
+if the underlying file or data source is successfully
+opened.
+If the open fails, it should call
+*archive_set_error*()
+to register an error code and message and return
+*ARCHIVE_FATAL*.
+
+The read callback is invoked whenever the library
+requires raw bytes from the archive.
+The read callback should read data into a buffer,
+set the
+{{{
+const void **buffer
+}}}
+argument to point to the available data, and
+return a count of the number of bytes available.
+The library will invoke the read callback again
+only after it has consumed this data.
+The library imposes no constraints on the size
+of the data blocks returned.
+On end-of-file, the read callback should
+return zero.
+On error, the read callback should invoke
+*archive_set_error*()
+to register an error code and message and
+return -1.
+
+The skip callback is invoked when the
+library wants to ignore a block of data.
+The return value is the number of bytes actually
+skipped, which may differ from the request.
+If the callback cannot skip data, it should return
+zero.
+If the skip callback is not provided (the
+function pointer is
+NULL ),
+the library will invoke the read function
+instead and simply discard the result.
+A skip callback can provide significant
+performance gains when reading uncompressed
+archives from slow disk drives or other media
+that can skip quickly.
+
+The close callback is invoked by archive_close when
+the archive processing is complete.
+The callback should return
+*ARCHIVE_OK*
+on success.
+On failure, the callback should invoke
+*archive_set_error*()
+to register an error code and message and
+return
+*ARCHIVE_FATAL.*
+== EXAMPLE ==
+The following illustrates basic usage of the library.
+In this example,
+the callback functions are simply wrappers around the standard
+*open*(2),
+*read*(2),
+and
+*close*(2)
+system calls.
+{{{
+void
+list_archive(const char *name)
+{
+  struct mydata *mydata;
+  struct archive *a;
+  struct archive_entry *entry;
+  mydata = malloc(sizeof(struct mydata));
+  a = archive_read_new();
+  mydata->name = name;
+  archive_read_support_compression_all(a);
+  archive_read_support_format_all(a);
+  archive_read_open(a, mydata, myopen, myread, myclose);
+  while (archive_read_next_header(a, &entry) == ARCHIVE_OK) {
+    printf("%s\\n",archive_entry_pathname(entry));
+    archive_read_data_skip(a);
+  }
+  archive_read_finish(a);
+  free(mydata);
+}
+ssize_t
+myread(struct archive *a, void *client_data, const void **buff)
+{
+  struct mydata *mydata = client_data;
+  *buff = mydata->buff;
+  return (read(mydata->fd, mydata->buff, 10240));
+}
+int
+myopen(struct archive *a, void *client_data)
+{
+  struct mydata *mydata = client_data;
+  mydata->fd = open(mydata->name, O_RDONLY);
+  return (mydata->fd >= 0 ? ARCHIVE_OK : ARCHIVE_FATAL);
+}
+int
+myclose(struct archive *a, void *client_data)
+{
+  struct mydata *mydata = client_data;
+  if (mydata->fd > 0)
+    close(mydata->fd);
+  return (ARCHIVE_OK);
+}
+}}}
+== RETURN VALUES ==
+Most functions return zero on success, non-zero on error.
+The possible return codes include:
+*ARCHIVE_OK*
+(the operation succeeded),
+*ARCHIVE_WARN*
+(the operation succeeded but a non-critical error was encountered),
+*ARCHIVE_EOF*
+(end-of-archive was encountered),
+*ARCHIVE_RETRY*
+(the operation failed but can be retried),
+and
+*ARCHIVE_FATAL*
+(there was a fatal error; the archive should be closed immediately).
+Detailed error codes and textual descriptions are available from the
+*archive_errno*()
+and
+*archive_error_string*()
+functions.
+
+*archive_read_new*()
+returns a pointer to a freshly allocated
+*struct archive*
+object.
+It returns
+NULL
+on error.
+
+*archive_read_data*()
+returns a count of bytes actually read or zero at the end of the entry.
+On error, a value of
+*ARCHIVE_FATAL*,
+*ARCHIVE_WARN*,
+or
+*ARCHIVE_RETRY*
+is returned and an error code and textual description can be retrieved from the
+*archive_errno*()
+and
+*archive_error_string*()
+functions.
+
+The library expects the client callbacks to behave similarly.
+If there is an error, you can use
+*archive_set_error*()
+to set an appropriate error code and description,
+then return one of the non-zero values above.
+(Note that the value eventually returned to the client may
+not be the same; many errors that are not critical at the level
+of basic I/O can prevent the archive from being properly read,
+thus most I/O errors eventually cause
+*ARCHIVE_FATAL*
+to be returned.)

+== DESCRIPTION ==
+These functions provide an API for reading information about
+objects on disk.
+In particular, they provide an interface for populating
+*struct archive_entry*
+objects.
+<dl>
+<dt>*archive_read_disk_new*()</dt><dd>
+Allocates and initializes a
+*struct archive*
+object suitable for reading object information from disk.
+</dd><dt>
+*archive_read_disk_set_symlink_logical*(),
+*archive_read_disk_set_symlink_physical*(),
+*archive_read_disk_set_symlink_hybrid*()
+</dt> <dd>
+This sets the mode used for handling symbolic links.
+The
+"logical"
+mode follows all symbolic links.
+The
+"physical"
+mode does not follow any symbolic links.
+The
+"hybrid"
+mode currently behaves identically to the
+"logical"
+mode.
+</dd><dt>
+*archive_read_disk_gname*(),
+*archive_read_disk_uname*()
+</dt> <dd>
+Returns a user or group name given a gid or uid value.
+By default, these always return a NULL string.
+</dd><dt>
+*archive_read_disk_set_gname_lookup*(),
+*archive_read_disk_set_uname_lookup*()
+</dt> <dd>
+These allow you to override the functions used for
+user and group name lookups.
+You may also provide a
+*void `*`*
+pointer to a private data structure and a cleanup function for
+that data.
+The cleanup function will be invoked when the
+*struct archive*
+object is destroyed or when new lookup functions are registered.
+</dd><dt>*archive_read_disk_set_standard_lookup*()</dt><dd>
+This convenience function installs a standard set of user
+and group name lookup functions.
+These functions use
+*getpwid*(3)
+and
+*getgrid*(3)
+to convert ids to names, defaulting to NULL if the names cannot
+be looked up.
+These functions also implement a simple memory cache to reduce
+the number of calls to
+*getpwid*(3)
+and
+*getgrid*(3).
+</dd><dt>*archive_read_disk_entry_from_file*()</dt><dd>
+Populates a
+*struct archive_entry*
+object with information about a particular file.
+The
+*archive_entry*
+object must have already been created with
+*archive_entry_new*(3)
+and at least one of the source path or path fields must already be set.
+(If both are set, the source path will be used.)
+
+Information is read from disk using the path name from the
+*struct archive_entry*
+object.
+If a file descriptor is provided, some information will be obtained using
+that file descriptor, on platforms that support the appropriate
+system calls.
+
+If a pointer to a
+*struct stat*
+is provided, information from that structure will be used instead
+of reading from the disk where appropriate.
+This can provide performance benefits in scenarios where
+*struct stat*
+information has already been read from the disk as a side effect
+of some other operation.
+(For example, directory traversal libraries often provide this information.)
+
+Where necessary, user and group ids are converted to user and group names
+using the currently registered lookup functions above.
+This affects the file ownership fields and ACL values in the
+*struct archive_entry*
+object.
+</dd><dt>*archive_read_close*()</dt><dd>
+This currently does nothing.
+</dd><dt>*archive_write_finish*()</dt><dd>
+Invokes
+*archive_write_close*()
+if it was not invoked manually, then releases all resources.
+</dd></dl>
+More information about the
+_struct_ archive
+object and the overall design of the library can be found in the
+*libarchive*(3)
+overview.
+== EXAMPLE ==
+The following illustrates basic usage of the library by
+showing how to use it to copy an item on disk into an archive.
+{{{
+void
+file_to_archive(struct archive *a, const char *name)
+{
+  char buff[8192];
+  size_t bytes_read;
+  struct archive *ard;
+  struct archive_entry *entry;
+  int fd;
+  ard = archive_read_disk_new();
+  archive_read_disk_set_standard_lookup(ard);
+  entry = archive_entry_new();
+  fd = open(name, O_RDONLY);
+  if (fd < 0)
+     return;
+  archive_entry_copy_sourcepath(entry, name);
+  archive_read_disk_entry_from_file(ard, entry, fd, NULL);
+  archive_write_header(a, entry);
+  while ((bytes_read = read(fd, buff, sizeof(buff))) > 0)
+    archive_write_data(a, buff, bytes_read);
+  archive_write_finish_entry(a);
+  archive_read_finish(ard);
+  archive_entry_free(entry);
+}
+}}}
+== RETURN VALUES ==
+Most functions return
+*ARCHIVE_OK*
+(zero) on success, or one of several negative
+error codes for errors.
+Specific error codes include:
+*ARCHIVE_RETRY*
+for operations that might succeed if retried,
+*ARCHIVE_WARN*
+for unusual conditions that do not prevent further operations, and
+*ARCHIVE_FATAL*
+for serious errors that make remaining operations impossible.
+The
+*archive_errno*(3)
+and
+*archive_error_string*(3)
+functions can be used to retrieve an appropriate error code and a
+textual error message.
+(See
+*archive_util*(3)
+for details.)
+
+*archive_read_disk_new*()
+returns a pointer to a newly-allocated
+*struct archive*
+object or NULL if the allocation failed for any reason.
+
+*archive_read_disk_gname*()
+and
+*archive_read_disk_uname*()
+return
+*const char `*`*
+pointers to the textual name or NULL if the lookup failed for any reason.
+The returned pointer points to internal storage that
+may be reused on the next call to either of these functions;
+callers should copy the string if they need to continue accessing it.
+

+== HISTORY ==
+The
+*libarchive*
+library first appeared in
+FreeBSD 5.3.
+The
+*archive_read_disk*
+interface was added to
+*libarchive* 2.6
+and first appeared in
+FreeBSD 8.0.
+== AUTHORS ==
+The
+*libarchive*
+library was written by
+Tim Kientzle  <kientzle@freebsd.org.>
+== BUGS ==
+The
+"standard"
+user name and group name lookup functions are not the defaults because
+*getgrid*(3)
+and
+*getpwid*(3)
+are sometimes too large for particular applications.
+The current design allows the application author to use a more
+compact implementation when appropriate.
+
+The full list of metadata read from disk by
+*archive_read_disk_entry_from_file*()
+is necessarily system-dependent.
+
+The
+*archive_read_disk_entry_from_file*()
+function reads as much information as it can from disk.
+Some method should be provided to limit this so that clients who
+do not need ACLs, for instance, can avoid the extra work needed
+to look up such information.
+
+This API should provide a set of methods for walking a directory tree.
+That would make it a direct parallel of the
+*archive_read*(3)
+API.
+When such methods are implemented, the
+"hybrid"
+symbolic link mode will make sense.

+library.
+<dl>
+<dt>*archive_clear_error*()</dt><dd>
+Clears any error information left over from a previous call.
+Not generally used in client code.
+</dd><dt>*archive_compression*()</dt><dd>
+Returns a numeric code indicating the current compression.
+This value is set by
+*archive_read_open*().
+</dd><dt>*archive_compression_name*()</dt><dd>
+Returns a text description of the current compression suitable for display.
+</dd><dt>*archive_copy_error*()</dt><dd>
+Copies error information from one archive to another.
+</dd><dt>*archive_errno*()</dt><dd>
+Returns a numeric error code (see
+*errno*(2))
+indicating the reason for the most recent error return.
+</dd><dt>*archive_error_string*()</dt><dd>
+Returns a textual error message suitable for display.
+The error message here is usually more specific than that
+obtained from passing the result of
+*archive_errno*()
+to
+*strerror*(3).
+</dd><dt>*archive_file_count*()</dt><dd>
+Returns a count of the number of files processed by this archive object.
+The count is incremented by calls to
+*archive_write_header*()
+or
+*archive_read_next_header*(.)
+</dd><dt>*archive_format*()</dt><dd>
+Returns a numeric code indicating the format of the current
+archive entry.
+This value is set by a successful call to
+*archive_read_next_header*().
+Note that it is common for this value to change from
+entry to entry.
+For example, a tar archive might have several entries that
+utilize GNU tar extensions and several entries that do not.
+These entries will have different format codes.
+</dd><dt>*archive_format_name*()</dt><dd>
+A textual description of the format of the current entry.
+</dd><dt>*archive_set_error*()</dt><dd>
+Sets the numeric error code and error description that will be returned
+by
+*archive_errno*()
+and
+*archive_error_string*().
+This function should be used within I/O callbacks to set system-specific
+error codes and error descriptions.
+This function accepts a printf-like format string and arguments.
+However, you should be careful to use only the following printf
+format specifiers:
+"%c",
+"%d",
+"%jd",
+"%jo",
+"%ju",
+"%jx",
+"%ld",
+"%lo",
+"%lu",
+"%lx",
+"%o",
+"%u",
+"%s",
+"%x",
+"%%".
+Field-width specifiers and other printf features are
+not uniformly supported and should not be used.

+== DESCRIPTION ==
+These functions provide a complete API for creating streaming
+archive files.
+The general process is to first create the
+*struct archive*
+object, set any desired options, initialize the archive, append entries, then
+close the archive and release all resources.
+The following summary describes the functions in approximately
+the order they are ordinarily used:
+<dl>
+<dt>*archive_write_new*()</dt><dd>
+Allocates and initializes a
+*struct archive*
+object suitable for writing a tar archive.
+</dd><dt>*archive_write_set_bytes_per_block*()</dt><dd>
+Sets the block size used for writing the archive data.
+Every call to the write callback function, except possibly the last one, will
+use this value for the length.
+The third parameter is a boolean that specifies whether or not the final block
+written will be padded to the full block size.
+If it is zero, the last block will not be padded.
+If it is non-zero, padding will be added both before and after compression.
+The default is to use a block size of 10240 bytes and to pad the last block.
+Note that a block size of zero will suppress internal blocking
+and cause writes to be sent directly to the write callback as they occur.
+</dd><dt>*archive_write_get_bytes_per_block*()</dt><dd>
+Retrieve the block size to be used for writing.
+A value of -1 here indicates that the library should use default values.
+A value of zero indicates that internal blocking is suppressed.
+</dd><dt>*archive_write_set_bytes_in_last_block*()</dt><dd>
+Sets the block size used for writing the last block.
+If this value is zero, the last block will be padded to the same size
+as the other blocks.
+Otherwise, the final block will be padded to a multiple of this size.
+In particular, setting it to 1 will cause the final block to not be padded.
+For compressed output, any padding generated by this option
+is applied only after the compression.
+The uncompressed data is always unpadded.
+The default is to pad the last block to the full block size (note that
+*archive_write_open_filename*()
+will set this based on the file type).
+Unlike the other
+"set"
+functions, this function can be called after the archive is opened.
+</dd><dt>*archive_write_get_bytes_in_last_block*()</dt><dd>
+Retrieve the currently-set value for last block size.
+A value of -1 here indicates that the library should use default values.
+</dd><dt>
+*archive_write_set_format_cpio*(),
+*archive_write_set_format_pax*(),
+*archive_write_set_format_pax_restricted*(),
+*archive_write_set_format_shar*(),
+*archive_write_set_format_shar_binary*(),
+*archive_write_set_format_ustar*()
+</dt> <dd>
+Sets the format that will be used for the archive.
+The library can write
+POSIX octet-oriented cpio format archives,
+POSIX-standard
+"pax interchange"
+format archives,
+traditional
+"shar"
+archives,
+enhanced
+"binary"
+shar archives that store a variety of file attributes and handle binary files,
+and
+POSIX-standard
+"ustar"
+archives.
+The pax interchange format is a backwards-compatible tar format that
+adds key/value attributes to each entry and supports arbitrary
+filenames, linknames, uids, sizes, etc.
+"Restricted pax interchange format"
+is the library default; this is the same as pax format, but suppresses
+the pax extended header for most normal files.
+In most cases, this will result in ordinary ustar archives.
+</dd><dt>
+*archive_write_set_compression_bzip2*(),
+*archive_write_set_compression_compress*(),
+*archive_write_set_compression_gzip*(),
+*archive_write_set_compression_none*()
+</dt> <dd>
+The resulting archive will be compressed as specified.
+Note that the compressed output is always properly blocked.
+</dd><dt>*archive_write_set_compression_program*()</dt><dd>
+The archive will be fed into the specified compression program.
+The output of that program is blocked and written to the client
+write callbacks.
+</dd><dt>
+*archive_write_set_compressor_options*(),
+*archive_write_set_format_options*(),
+*archive_write_set_options*()
+</dt> <dd>
+Specifies options that will be passed to the currently-enabled
+compressor and/or format writer.
+The argument is a comma-separated list of individual options.
+Individual options have one of the following forms:
+<dl>
+<dt>_option=value_</dt><dd>
+The option/value pair will be provided to every module.
+Modules that do not accept an option with this name will ignore it.
+</dd><dt>_option_</dt><dd>
+The option will be provided to every module with a value of
+"1".
+</dd><dt>_!option_</dt><dd>
+The option will be provided to every module with a NULL value.
+</dd><dt>_module:option=value_, _module:option_, _module:!option_</dt><dd>
+As above, but the corresponding option and value will be provided
+only to modules whose name matches
+_module_.
+</dd></dl>
+The return value will be
+*ARCHIVE_OK*
+if any module accepts the option, or
+*ARCHIVE_WARN*
+if no module accepted the option, or
+*ARCHIVE_FATAL*
+if there was a fatal error while attempting to process the option.
+
+The currently supported options are:
+<dl>
+<dt>Compressor gzip</dt><dd>
+<dl>
+<dt>*compression-level*</dt><dd>
+The value is interpreted as a decimal integer specifying the
+gzip compression level.
+</dd></dl>
+</dd><dt>Compressor xz</dt><dd>
+<dl>
+<dt>*compression-level*</dt><dd>
+The value is interpreted as a decimal integer specifying the
+compression level.
+</dd></dl>
+</dd><dt>Format mtree</dt><dd>
+<dl>
+<dt>*cksum*, *device*, *flags*, *gid*, *gname*, *indent*, *link*, *md5*, *mode*, *nlink*, *rmd160*, *sha1*, *sha256*, *sha384*, *sha512*, *size*, *time*, *uid*, *uname*</dt><dd>
+Enable a particular keyword in the mtree output.
+Prefix with an exclamation mark to disable the corresponding keyword.
+The default is equivalent to
+"device, flags, gid, gname, link, mode, nlink, size, time, type, uid, uname".
+</dd><dt>*all*</dt><dd>
+Enables all of the above keywords.
+</dd><dt>*use-set*</dt><dd>
+Enables generation of
+*/set*
+lines that specify default values for the following files and/or directories.
+</dd><dt>*indent*</dt><dd>
+XXX needs explanation XXX
+</dd></dl>
+</dd></dl>
+</dd><dt>*archive_write_open*()</dt><dd>
+Freeze the settings, open the archive, and prepare for writing entries.
+This is the most generic form of this function, which accepts
+pointers to three callback functions which will be invoked by
+the compression layer to write the constructed archive.
+</dd><dt>*archive_write_open_fd*()</dt><dd>
+A convenience form of
+*archive_write_open*()
+that accepts a file descriptor.
+The
+*archive_write_open_fd*()
+function is safe for use with tape drives or other
+block-oriented devices.
+</dd><dt>*archive_write_open_FILE*()</dt><dd>
+A convenience form of
+*archive_write_open*()
+that accepts a
+*FILE `*`*
+pointer.
+Note that
+*archive_write_open_FILE*()
+is not safe for writing to tape drives or other devices
+that require correct blocking.
+</dd><dt>*archive_write_open_file*()</dt><dd>
+A deprecated synonym for
+*archive_write_open_filename*().
+</dd><dt>*archive_write_open_filename*()</dt><dd>
+A convenience form of
+*archive_write_open*()
+that accepts a filename.
+A NULL argument indicates that the output should be written to standard output;
+an argument of
+"-"
+will open a file with that name.
+If you have not invoked
+*archive_write_set_bytes_in_last_block*(),
+then
+*archive_write_open_filename*()
+will adjust the last-block padding depending on the file:
+it will enable padding when writing to standard output or
+to a character or block device node, it will disable padding otherwise.
+You can override this by manually invoking
+*archive_write_set_bytes_in_last_block*()
+before calling
+*archive_write_open*().
+The
+*archive_write_open_filename*()
+function is safe for use with tape drives or other
+block-oriented devices.
+</dd><dt>*archive_write_open_memory*()</dt><dd>
+A convenience form of
+*archive_write_open*()
+that accepts a pointer to a block of memory that will receive
+the archive.
+The final
+*size_t `*`*
+argument points to a variable that will be updated
+after each write to reflect how much of the buffer
+is currently in use.
+You should be careful to ensure that this variable
+remains allocated until after the archive is
+closed.
+</dd><dt>*archive_write_header*()</dt><dd>
+Build and write a header using the data in the provided
+*struct archive_entry*
+structure.
+See
+*archive_entry*(3)
+for information on creating and populating
+*struct archive_entry*
+objects.
+</dd><dt>*archive_write_data*()</dt><dd>
+Write data corresponding to the header just written.
+Returns number of bytes written or -1 on error.
+</dd><dt>*archive_write_finish_entry*()</dt><dd>
+Close out the entry just written.
+In particular, this writes out the final padding required by some formats.
+Ordinarily, clients never need to call this, as it
+is called automatically by
+*archive_write_next_header*()
+and
+*archive_write_close*()
+as needed.
+</dd><dt>*archive_write_close*()</dt><dd>
+Complete the archive and invoke the close callback.
+</dd><dt>*archive_write_finish*()</dt><dd>
+Invokes
+*archive_write_close*()
+if it was not invoked manually, then releases all resources.
+Note that this function was declared to return
+*void*
+in libarchive 1.x, which made it impossible to detect errors when
+*archive_write_close*()
+was invoked implicitly from this function.
+This is corrected beginning with libarchive 2.0.
+</dd></dl>
+More information about the
+_struct_ archive
+object and the overall design of the library can be found in the
+*libarchive*(3)
+overview.
+== IMPLEMENTATION ==
+Compression support is built-in to libarchive, which uses zlib and bzlib
+to handle gzip and bzip2 compression, respectively.
+== CLIENT CALLBACKS ==
+To use this library, you will need to define and register
+callback functions that will be invoked to write data to the
+resulting archive.
+These functions are registered by calling
+*archive_write_open*():
+<ul>
+<li>
+*typedef int*
+*archive_open_callback*(_struct archive `*`_, _void `*`client_data_)
+</li></ul>
+
+The open callback is invoked by
+*archive_write_open*().
+It should return
+*ARCHIVE_OK*
+if the underlying file or data source is successfully
+opened.
+If the open fails, it should call
+*archive_set_error*()
+to register an error code and message and return
+*ARCHIVE_FATAL*.
+<ul>
+<li>
+*typedef ssize_t*
+*archive_write_callback*(_struct archive `*`_, _void `*`client_data_, _const void `*`buffer_, _size_t length_)
+</li></ul>
+
+The write callback is invoked whenever the library
+needs to write raw bytes to the archive.
+For correct blocking, each call to the write callback function
+should translate into a single
+*write*(2)
+system call.
+This is especially critical when writing archives to tape drives.
+On success, the write callback should return the
+number of bytes actually written.
+On error, the callback should invoke
+*archive_set_error*()
+to register an error code and message and return -1.
+<ul>
+<li>
+*typedef int*
+*archive_close_callback*(_struct archive `*`_, _void `*`client_data_)
+</li></ul>
+
+The close callback is invoked by archive_close when
+the archive processing is complete.
+The callback should return
+*ARCHIVE_OK*
+on success.
+On failure, the callback should invoke
+*archive_set_error*()
+to register an error code and message and
+return
+*ARCHIVE_FATAL.*
+== EXAMPLE ==
+The following sketch illustrates basic usage of the library.
+In this example,
+the callback functions are simply wrappers around the standard
+*open*(2),
+*write*(2),
+and
+*close*(2)
+system calls.

+== RETURN VALUES ==
+Most functions return
+*ARCHIVE_OK*
+(zero) on success, or one of several non-zero
+error codes for errors.
+Specific error codes include:
+*ARCHIVE_RETRY*
+for operations that might succeed if retried,
+*ARCHIVE_WARN*
+for unusual conditions that do not prevent further operations, and
+*ARCHIVE_FATAL*
+for serious errors that make remaining operations impossible.
+The
+*archive_errno*()
+and
+*archive_error_string*()
+functions can be used to retrieve an appropriate error code and a
+textual error message.
+
+*archive_write_new*()
+returns a pointer to a newly-allocated
+*struct archive*
+object.
+
+*archive_write_data*()
+returns a count of the number of bytes actually written.
+On error, -1 is returned and the
+*archive_errno*()
+and
+*archive_error_string*()
+functions will return appropriate values.
+Note that if the client-provided write callback function
+returns a non-zero value, that error will be propagated back to the caller
+through whatever API function resulted in that call, which
+may include
+*archive_write_header*(),
+*archive_write_data*(),
+*archive_write_close*(),

+== BUGS ==
+There are many peculiar bugs in historic tar implementations that may cause
+certain programs to reject archives written by this library.
+For example, several historic implementations calculated header checksums
+incorrectly and will thus reject valid archives; GNU tar does not fully support
+pax interchange format; some old tar implementations required specific
+field terminations.
+
+The default pax interchange format eliminates most of the historic
+tar limitations and provides a generic key/value attribute facility
+for vendor-defined extensions.
+One oversight in POSIX is the failure to provide a standard attribute
+for large device numbers.
+This library uses
+"SCHILY.devminor"
+and
+"SCHILY.devmajor"
+for device numbers that exceed the range supported by the backwards-compatible
+ustar header.
+These keys are compatible with Joerg Schilling's
+*star*
+archiver.
+Other implementations may not recognize these keys and will thus be unable
+to correctly restore device nodes with large device numbers from archives
+created by this library.

+== DESCRIPTION ==
+These functions provide a complete API for creating objects on
+disk from
+*struct archive_entry*
+descriptions.
+They are most naturally used when extracting objects from an archive
+using the
+*archive_read*()
+interface.
+The general process is to read
+*struct archive_entry*
+objects from an archive, then write those objects to a
+*struct archive*
+object created using the
+*archive_write_disk*()
+family functions.
+This interface is deliberately very similar to the
+*archive_write*()
+interface used to write objects to a streaming archive.
+<dl>
+<dt>*archive_write_disk_new*()</dt><dd>
+Allocates and initializes a
+*struct archive*
+object suitable for writing objects to disk.
+</dd><dt>*archive_write_disk_set_skip_file*()</dt><dd>
+Records the device and inode numbers of a file that should not be
+overwritten.
+This is typically used to ensure that an extraction process does not
+overwrite the archive from which objects are being read.
+This capability is technically unnecessary but can be a significant
+performance optimization in practice.
+</dd><dt>*archive_write_disk_set_options*()</dt><dd>
+The options field consists of a bitwise OR of one or more of the
+following values:
+<dl>
+<dt>*ARCHIVE_EXTRACT_OWNER*</dt><dd>
+The user and group IDs should be set on the restored file.
+By default, the user and group IDs are not restored.
+</dd><dt>*ARCHIVE_EXTRACT_PERM*</dt><dd>
+Full permissions (including SGID, SUID, and sticky bits) should
+be restored exactly as specified, without obeying the
+current umask.
+Note that SUID and SGID bits can only be restored if the
+user and group ID of the object on disk are correct.
+If
+*ARCHIVE_EXTRACT_OWNER*
+is not specified, then SUID and SGID bits will only be restored
+if the default user and group IDs of newly-created objects on disk
+happen to match those specified in the archive entry.
+By default, only basic permissions are restored, and umask is obeyed.
+</dd><dt>*ARCHIVE_EXTRACT_TIME*</dt><dd>
+The timestamps (mtime, ctime, and atime) should be restored.
+By default, they are ignored.
+Note that restoring of atime is not currently supported.
+</dd><dt>*ARCHIVE_EXTRACT_NO_OVERWRITE*</dt><dd>
+Existing files on disk will not be overwritten.
+By default, existing regular files are truncated and overwritten;
+existing directories will have their permissions updated;
+other pre-existing objects are unlinked and recreated from scratch.
+</dd><dt>*ARCHIVE_EXTRACT_UNLINK*</dt><dd>
+Existing files on disk will be unlinked before any attempt to
+create them.
+In some cases, this can prove to be a significant performance improvement.
+By default, existing files are truncated and rewritten, but
+the file is not recreated.
+In particular, the default behavior does not break existing hard links.
+</dd><dt>*ARCHIVE_EXTRACT_ACL*</dt><dd>
+Attempt to restore ACLs.
+By default, extended ACLs are ignored.
+</dd><dt>*ARCHIVE_EXTRACT_FFLAGS*</dt><dd>
+Attempt to restore extended file flags.
+By default, file flags are ignored.
+</dd><dt>*ARCHIVE_EXTRACT_XATTR*</dt><dd>
+Attempt to restore POSIX.1e extended attributes.
+By default, they are ignored.
+</dd><dt>*ARCHIVE_EXTRACT_SECURE_SYMLINKS*</dt><dd>
+Refuse to extract any object whose final location would be altered
+by a symlink on disk.
+This is intended to help guard against a variety of mischief
+caused by archives that (deliberately or otherwise) extract
+files outside of the current directory.
+The default is not to perform this check.
+If
+*ARCHIVE_EXTRACT_UNLINK*
+is specified together with this option, the library will
+remove any intermediate symlinks it finds and return an
+error only if such symlink could not be removed.
+</dd><dt>*ARCHIVE_EXTRACT_SECURE_NODOTDOT*</dt><dd>
+Refuse to extract a path that contains a
+_.._
+element anywhere within it.
+The default is to not refuse such paths.
+Note that paths ending in
+_.._
+always cause an error, regardless of this flag.
+</dd><dt>*ARCHIVE_EXTRACT_SPARSE*</dt><dd>
+Scan data for blocks of NUL bytes and try to recreate them with holes.
+This results in sparse files, independent of whether the archive format
+supports or uses them.
+</dd></dl>
+</dd><dt>
+*archive_write_disk_set_group_lookup*(),
+*archive_write_disk_set_user_lookup*()
+</dt> <dd>
+The
+*struct archive_entry*
+objects contain both names and ids that can be used to identify users
+and groups.
+These names and ids describe the ownership of the file itself and
+also appear in ACL lists.
+By default, the library uses the ids and ignores the names, but
+this can be overridden by registering user and group lookup functions.
+To register, you must provide a lookup function which
+accepts both a name and id and returns a suitable id.
+You may also provide a
+*void `*`*
+pointer to a private data structure and a cleanup function for
+that data.
+The cleanup function will be invoked when the
+*struct archive*
+object is destroyed.
+</dd><dt>*archive_write_disk_set_standard_lookup*()</dt><dd>
+This convenience function installs a standard set of user
+and group lookup functions.
+These functions use
+*getpwnam*(3)
+and
+*getgrnam*(3)
+to convert names to ids, defaulting to the ids if the names cannot
+be looked up.
+These functions also implement a simple memory cache to reduce
+the number of calls to
+*getpwnam*(3)
+and
+*getgrnam*(3).
+</dd><dt>*archive_write_header*()</dt><dd>
+Build and write a header using the data in the provided
+*struct archive_entry*
+structure.
+See
+*archive_entry*(3)
+for information on creating and populating
+*struct archive_entry*
+objects.
+</dd><dt>*archive_write_data*()</dt><dd>
+Write data corresponding to the header just written.
+Returns number of bytes written or -1 on error.
+</dd><dt>*archive_write_finish_entry*()</dt><dd>
+Close out the entry just written.
+Ordinarily, clients never need to call this, as it
+is called automatically by
+*archive_write_next_header*()
+and
+*archive_write_close*()
+as needed.
+</dd><dt>*archive_write_close*()</dt><dd>
+Set any attributes that could not be set during the initial restore.
+For example, directory timestamps are not restored initially because
+restoring a subsequent file would alter that timestamp.
+Similarly, non-writable directories are initially created with
+write permissions (so that their contents can be restored).
+The
+*archive_write_disk_new*
+library maintains a list of all such deferred attributes and
+sets them when this function is invoked.
+</dd><dt>*archive_write_finish*()</dt><dd>
+Invokes
+*archive_write_close*()
+if it was not invoked manually, then releases all resources.
+</dd></dl>
+More information about the
+_struct_ archive
+object and the overall design of the library can be found in the
+*libarchive*(3)
+overview.
+Many of these functions are also documented under
+*archive_write*(3).
+== RETURN VALUES ==
+Most functions return
+*ARCHIVE_OK*
+(zero) on success, or one of several non-zero
+error codes for errors.
+Specific error codes include:
+*ARCHIVE_RETRY*
+for operations that might succeed if retried,
+*ARCHIVE_WARN*
+for unusual conditions that do not prevent further operations, and
+*ARCHIVE_FATAL*
+for serious errors that make remaining operations impossible.
+The
+*archive_errno*()
+and
+*archive_error_string*()
+functions can be used to retrieve an appropriate error code and a
+textual error message.
+
+*archive_write_disk_new*()
+returns a pointer to a newly-allocated
+*struct archive*
+object.
+
+*archive_write_data*()
+returns a count of the number of bytes actually written.
+On error, -1 is returned and the
+*archive_errno*()
+and
+*archive_error_string*()
+functions will return appropriate values.

+== AUTHORS ==

+== BUGS ==
+Directories are actually extracted in two distinct phases.
+Directories are created during
+*archive_write_header*(),
+but final permissions are not set until
+*archive_write_close*().
+This separation is necessary to correctly handle borderline
+cases such as a non-writable directory containing
+files, but can cause unexpected results.
+In particular, directory permissions are not fully
+restored until the archive is closed.
+If you use
+*chdir*(2)
+to change the current directory between calls to
+*archive_read_extract*()
+or before calling
+*archive_read_close*(),
+you may confuse the permission-setting logic with
+the result that directory permissions are restored
+incorrectly.
+
+The library attempts to create objects with filenames longer than
+*PATH_MAX*
+by creating prefixes of the full path and changing the current directory.
+Currently, this logic is limited in scope; the fixup pass does
+not work correctly for such objects and the symlink security check
+option disables the support for very long pathnames.
+
+Restoring the path
+_aa/../bb_
+does create each intermediate directory.
+In particular, the directory
+_aa_
+is created as well as the final object
+_bb_.
+In theory, this can be exploited to create an entire directory heirarchy
+with a single request.
+Of course, this does not work if the
+*ARCHIVE_EXTRACT_NODOTDOT*
+option is specified.
+
+Implicit directories are always created obeying the current umask.
+Explicit objects are created obeying the current umask unless
+*ARCHIVE_EXTRACT_PERM*
+is specified, in which case they current umask is ignored.
+
+SGID and SUID bits are restored only if the correct user and
+group could be set.
+If
+*ARCHIVE_EXTRACT_OWNER*
+is not specified, then no attempt is made to set the ownership.
+In this case, SGID and SUID bits are restored only if the
+user and group of the final object happen to match those specified
+in the entry.
+
+The
+"standard"
+user-id and group-id lookup functions are not the defaults because
+*getgrnam*(3)
+and
+*getpwnam*(3)
+are sometimes too large for particular applications.
+The current design allows the application author to use a more
+compact implementation when appropriate.
+
+There should be a corresponding
+*archive_read_disk*
+interface that walks a directory heirarchy and returns archive
+entry objects.

+</dd></dl>
+== ENVIRONMENT ==
+The following environment variables affect the execution of
+*cpio*:
+<dl>
+<dt>*LANG*
+The locale to use.
+See
+*environ*(7)
+for more information.
+</dt><dt>*TZ*
+The timezone to use when displaying dates.
+See
+*environ*(7)
+for more information.
+</dt></dl>
+== EXIT STATUS ==
+The *cpio* utility exits 0 on success, and >0 if an error occurs.
+== EXAMPLES ==
+The
+*cpio*
+command is traditionally used to copy file heirarchies in conjunction
+with the
+*find*(1)
+command.
+The first example here simply copies all files from
+_src_
+to
+_dest_:
+{{{
+find src | cpio -pmud dest
+}}}
+
+By carefully selecting options to the
+*find*(1)
+command and combining it with other standard utilities,
+it is possible to exercise very fine control over which files are copied.
+This next example copies files from
+_src_
+to
+_dest_
+that are more than 2 days old and whose names match a particular pattern:
+{{{
+find src -mtime _+2_ | grep foo[bar] | cpio -pdmu dest
+}}}
+
+This example copies files from
+_src_
+to
+_dest_
+that are more than 2 days old and which contain the word
+"foobar":
+{{{
+find src -mtime _+2_ | xargs grep -l foobar | cpio -pdmu dest
+}}}
+== COMPATIBILITY ==
+The mode options i, o, and p and the options
+a, B, c, d, f, l, m, r, t, u, and v comply with SUSv2.
+
+The old POSIX.1 standard specified that only
+*-i*,
+*-o*,
+and
+*-p*
+were interpreted as command-line options.
+Each took a single argument of a list of modifier
+characters.
+For example, the standard syntax allows
+*-imu*
+but does not support
+*-miu*
+or
+*-i* *-m* *-u*,
+since
+_m_
+and
+_u_
+are only modifiers to
+*-i*,
+they are not command-line options in their own right.
+The syntax supported by this implementation is backwards-compatible
+with the standard.
+For best compatibility, scripts should limit themselves to the
+standard syntax.

+but was dropped from
+IEEE Std 1003.1-2001 (``POSIX.1'').

+The cpio, ustar, and pax interchange file formats are defined by
+IEEE Std 1003.1-2001 (``POSIX.1'')
+for the pax command.
+== HISTORY ==
+The original
+*cpio*
+and
+*find*
+utilities were written by Dick Haight
+while working in AT&T's Unix Support Group.
+They first appeared in 1977 in PWB/UNIX 1.0, the
+"Programmer's Work Bench"
+system developed for use within AT&T.
+They were first released outside of AT&T as part of System III Unix in 1981.
+As a result,
+*cpio*
+actually predates
+*tar*,
+even though it was not well-known outside of AT&T until some time later.
+
+This is a complete re-implementation based on the
+*libarchive*(3)
+library.
+== BUGS ==
+The cpio archive format has several basic limitations:
+It does not store user and group names, only numbers.
+As a result, it cannot be reliably used to transfer
+files between systems with dissimilar user and group numbering.
+Older cpio formats limit the user and group numbers to
+16 or 18 bits, which is insufficient for modern systems.
+The cpio archive formats cannot support files over 4 gigabytes,
+except for the
+"odc"
+variant, which can support files up to 8 gigabytes.

+== DESCRIPTION ==
+*tar*
+creates and manipulates streaming archive files.
+This implementation can extract from tar, pax, cpio, zip, jar, ar,
+and ISO 9660 cdrom images and can create tar, pax, cpio, ar,
+and shar archives.
+
+The first synopsis form shows a
+"bundled"
+option word.
+This usage is provided for compatibility with historical implementations.
+See COMPATIBILITY below for details.
+
+The other synopsis forms show the preferred usage.
+The first option to
+*tar*
+is a mode indicator from the following list:
+<dl>
+<dt>*-c*</dt><dd>
+Create a new archive containing the specified items.
+</dd><dt>*-r*</dt><dd>
+Like
+*-c*,
+but new entries are appended to the archive.
+Note that this only works on uncompressed archives stored in regular files.
+The
+*-f*
+option is required.
+</dd><dt>*-t*</dt><dd>
+List archive contents to stdout.
+</dd><dt>*-u*</dt><dd>
+Like
+*-r*,
+but new entries are added only if they have a modification date
+newer than the corresponding entry in the archive.
+Note that this only works on uncompressed archives stored in regular files.
+The
+*-f*
+option is required.
+</dd><dt>*-x*</dt><dd>
+Extract to disk from the archive.
+If a file with the same name appears more than once in the archive,
+each copy will be extracted, with later copies overwriting (replacing)
+earlier copies.
+</dd></dl>
+
+In
+*-c*,
+*-r*,
+or
+*-u*
+mode, each specified file or directory is added to the
+archive in the order specified on the command line.
+By default, the contents of each directory are also archived.
+
+In extract or list mode, the entire command line
+is read and parsed before the archive is opened.
+The pathnames or patterns on the command line indicate
+which items in the archive should be processed.
+Patterns are shell-style globbing patterns as
+documented in
+*tcsh*(1).
+== OPTIONS ==
+Unless specifically stated otherwise, options are applicable in
+all operating modes.
+<dl>
+<dt>*@*_archive_</dt><dd>
+(c and r mode only)
+The specified archive is opened and the entries
+in it will be appended to the current archive.
+As a simple example,
+{{{
+tar -c -f - newfile @original.tar
+}}}
+writes a new archive to standard output containing a file
+_newfile_
+and all of the entries from
+_original.tar_.
+In contrast,
+{{{
+tar -c -f - newfile original.tar
+}}}
+creates a new archive with only two entries.
+Similarly,
+{{{
+tar -czf - --format pax @-
+}}}
+reads an archive from standard input (whose format will be determined
+automatically) and converts it into a gzip-compressed
+pax-format archive on stdout.
+In this way,
+*tar*
+can be used to convert archives from one format to another.
+</dd><dt>*-b* _blocksize_</dt><dd>
+Specify the block size, in 512-byte records, for tape drive I/O.
+As a rule, this argument is only needed when reading from or writing
+to tape drives, and usually not even then as the default block size of
+20 records (10240 bytes) is very common.
+</dd><dt>*-C* _directory_</dt><dd>
+In c and r mode, this changes the directory before adding
+the following files.
+In x mode, change directories after opening the archive
+but before extracting entries from the archive.
+</dd><dt>*--check-links*</dt><dd>
+(c and r modes only)
+Issue a warning message unless all links to each file are archived.
+</dd><dt>*--chroot*</dt><dd>
+(x mode only)
+*chroot*()
+to the current directory after processing any
+*-C*
+options and before extracting any files.
+</dd><dt>*--exclude* _pattern_</dt><dd>
+Do not process files or directories that match the
+specified pattern.
+Note that exclusions take precedence over patterns or filenames
+specified on the command line.
+</dd><dt>*--format* _format_</dt><dd>
+(c, r, u mode only)
+Use the specified format for the created archive.
+Supported formats include
+"cpio",
+"pax",
+"shar",
+and
+"ustar".
+Other formats may also be supported; see
+*libarchive-formats*(5)
+for more information about currently-supported formats.
+In r and u modes, when extending an existing archive, the format specified
+here must be compatible with the format of the existing archive on disk.
+</dd><dt>*-f* _file_</dt><dd>
+Read the archive from or write the archive to the specified file.
+The filename can be
+_-_
+for standard input or standard output.
+If not specified, the default tape device will be used.
+(On
+FreeBSD,
+the default tape device is
+_/dev/sa0_.)
+</dd><dt>*-H*</dt><dd>
+(c and r mode only)
+Symbolic links named on the command line will be followed; the
+target of the link will be archived, not the link itself.
+</dd><dt>*-h*</dt><dd>
+(c and r mode only)
+Synonym for
+*-L*.
+</dd><dt>*-I*</dt><dd>
+Synonym for
+*-T*.
+</dd><dt>*--include* _pattern_</dt><dd>
+Process only files or directories that match the specified pattern.
+Note that exclusions specified with
+*--exclude*
+take precedence over inclusions.
+If no inclusions are explicitly specified, all entries are processed by
+default.
+The
+*--include*
+option is especially useful when filtering archives.
+For example, the command
+{{{
+tar -c -f new.tar --include='*foo*' @old.tgz
+}}}
+creates a new archive
+_new.tar_
+containing only the entries from
+_old.tgz_
+containing the string
+Sq foo.
+</dd><dt>*-j*</dt><dd>
+(c mode only)
+Compress the resulting archive with
+*bzip2*(1).
+In extract or list modes, this option is ignored.
+Note that, unlike other
+*tar*
+implementations, this implementation recognizes bzip2 compression
+automatically when reading archives.
+</dd><dt>*-k*</dt><dd>
+(x mode only)
+Do not overwrite existing files.
+In particular, if a file appears more than once in an archive,
+later copies will not overwrite earlier copies.
+</dd><dt>*--keep-newer-files*</dt><dd>
+(x mode only)
+Do not overwrite existing files that are newer than the
+versions appearing in the archive being extracted.
+</dd><dt>*-L*</dt><dd>
+(c and r mode only)
+All symbolic links will be followed.
+Normally, symbolic links are archived as such.
+With this option, the target of the link will be archived instead.
+</dd><dt>*-l*</dt><dd>
+This is a synonym for the
+*--check-links*
+option.
+</dd><dt>*-m*</dt><dd>
+(x mode only)
+Do not extract modification time.
+By default, the modification time is set to the time stored in the archive.
+</dd><dt>*-n*</dt><dd>
+(c, r, u modes only)
+Do not recursively archive the contents of directories.
+</dd><dt>*--newer* _date_</dt><dd>
+(c, r, u modes only)
+Only include files and directories newer than the specified date.
+This compares ctime entries.
+</dd><dt>*--newer-mtime* _date_</dt><dd>
+(c, r, u modes only)
+Like
+*--newer*,
+except it compares mtime entries instead of ctime entries.
+</dd><dt>*--newer-than* _file_</dt><dd>
+(c, r, u modes only)
+Only include files and directories newer than the specified file.
+This compares ctime entries.
+</dd><dt>*--newer-mtime-than* _file_</dt><dd>
+(c, r, u modes only)
+Like
+*--newer-than*,
+except it compares mtime entries instead of ctime entries.
+</dd><dt>*--nodump*</dt><dd>
+(c and r modes only)
+Honor the nodump file flag by skipping this file.
+</dd><dt>*--null*</dt><dd>
+(use with
+*-I*,
+*-T*,
+or
+*-X*)
+Filenames or patterns are separated by null characters,
+not by newlines.
+This is often used to read filenames output by the
+*-print0*
+option to
+*find*(1).
+</dd><dt>*--numeric-owner*</dt><dd>
+(x mode only)
+Ignore symbolic user and group names when restoring archives to disk,
+only numeric uid and gid values will be obeyed.
+</dd><dt>*-O*</dt><dd>
+(x, t modes only)
+In extract (-x) mode, files will be written to standard out rather than
+being extracted to disk.
+In list (-t) mode, the file listing will be written to stderr rather than
+the usual stdout.
+</dd><dt>*-o*</dt><dd>
+(x mode)
+Use the user and group of the user running the program rather
+than those specified in the archive.
+Note that this has no significance unless
+*-p*
+is specified, and the program is being run by the root user.
+In this case, the file modes and flags from
+the archive will be restored, but ACLs or owner information in
+the archive will be discarded.
+</dd><dt>*-o*</dt><dd>
+(c, r, u mode)
+A synonym for
+*--format* _ustar_
+</dd><dt>*--one-file-system*</dt><dd>
+(c, r, and u modes)
+Do not cross mount points.
+</dd><dt>*--options* _options_</dt><dd>
+Select optional behaviors for particular modules.
+The argument is a text string containing comma-separated
+keywords and values.
+These are passed to the modules that handle particular
+formats to control how those formats will behave.
+Each option has one of the following forms:
+<dl>
+<dt>_key=value_</dt><dd>
+The key will be set to the specified value in every module that supports it.
+Modules that do not support this key will ignore it.
+</dd><dt>_key_</dt><dd>
+The key will be enabled in every module that supports it.
+This is equivalent to
+_key_*=1*.
+</dd><dt>_!key_</dt><dd>
+The key will be disabled in every module that supports it.
+</dd><dt>_module:key=value_, _module:key_, _module:!key_</dt><dd>
+As above, but the corresponding key and value will be provided
+only to modules whose name matches
+_module_.
+</dd></dl>
+The currently supported modules and keys are:
+<dl>
+<dt>*iso9660:joliet*</dt><dd>
+Support Joliet extensions.
+This is enabled by default, use
+*!joliet*
+or
+*iso9660:!joliet*
+to disable.
+</dd><dt>*iso9660:rockridge*</dt><dd>
+Support Rock Ridge extensions.
+This is enabled by default, use
+*!rockridge*
+or
+*iso9660:!rockridge*
+to disable.
+</dd><dt>*gzip:compression-level*</dt><dd>
+A decimal integer from 0 to 9 specifying the gzip compression level.
+</dd><dt>*xz:compression-level*</dt><dd>
+A decimal integer from 0 to 9 specifying the xz compression level.
+</dd><dt>*mtree:*_keyword_</dt><dd>
+The mtree writer module allows you to specify which mtree keywords
+will be included in the output.
+Supported keywords include:
+*cksum*, *device*, *flags*, *gid*, *gname*, *indent*,
+*link*, *md5*, *mode*, *nlink*, *rmd160*, *sha1*, *sha256*,
+*sha384*, *sha512*, *size*, *time*, *uid*, *uname*.
+The default is equivalent to:
+"device, flags, gid, gname, link, mode, nlink, size, time, type, uid, uname".
+</dd><dt>*mtree:all*</dt><dd>
+Enables all of the above keywords.
+You can also use
+*mtree:!all*
+to disable all keywords.
+</dd><dt>*mtree:use-set*</dt><dd>
+Enable generation of
+*/set*
+lines in the output.
+</dd><dt>*mtree:indent*</dt><dd>
+Produce human-readable output by indenting options and splitting lines
+to fit into 80 columns.
+</dd><dt>*zip:compression*=_type_</dt><dd>
+Use
+_type_
+as compression method.
+Supported values are store (uncompressed) and deflate (gzip algorithm).
+</dd></dl>
+If a provided option is not supported by any module, that
+is a fatal error.
+</dd><dt>*-P*</dt><dd>
+Preserve pathnames.
+By default, absolute pathnames (those that begin with a /
+character) have the leading slash removed both when creating archives
+and extracting from them.
+Also,
+*tar*
+will refuse to extract archive entries whose pathnames contain
+_.._
+or whose target directory would be altered by a symlink.
+This option suppresses these behaviors.
+</dd><dt>*-p*</dt><dd>
+(x mode only)
+Preserve file permissions.
+Attempt to restore the full permissions, including owner, file modes, file
+flags and ACLs, if available, for each item extracted from the archive.
+By default, newly-created files are owned by the user running
+*tar*,
+the file mode is restored for newly-created regular files, and
+all other types of entries receive default permissions.
+If
+*tar*
+is being run by root, the default is to restore the owner unless the
+*-o*
+option is also specified.
+</dd><dt>*-q* (*--fast-read*)</dt><dd>
+(x and t mode only)
+Extract or list only the first archive entry that matches each pattern
+or filename operand.
+Exit as soon as each specified pattern or filename has been matched.
+By default, the archive is always read to the very end, since
+there can be multiple entries with the same name and, by convention,
+later entries overwrite earlier entries.
+This option is provided as a performance optimization.
+</dd><dt>*-S*</dt><dd>
+(x mode only)
+Extract files as sparse files.
+For every block on disk, check first if it contains only NULL bytes and seek
+over it otherwise.
+This works similiar to the conv=sparse option of dd.
+</dd><dt>*--strip-components* _count_</dt><dd>
+(x mode only)
+Remove the specified number of leading path elements.
+Pathnames with fewer elements will be silently skipped.
+Note that the pathname is edited after checking inclusion/exclusion patterns
+but before security checks.
+</dd><dt>*-s* _pattern_</dt><dd>
+Modify file or archive member names according to
+_pattern_.
+The pattern has the format
+_/old/new/_`[`gps`]`
+where
+_old_
+is a basic regular expression,
+_new_
+is the replacement string of the matched part,
+and the optional trailing letters modify
+how the replacement is handled.
+If
+_old_
+is not matched, the pattern is skipped.
+Within
+_new_,
+~ is substituted with the match, \1 to \9 with the content of
+the corresponding captured group.
+The optional trailing g specifies that matching should continue
+after the matched part and stopped on the first unmatched pattern.
+The optional trailing s specifies that the pattern applies to the value
+of symbolic links.
+The optional trailing p specifies that after a successful substitution
+the original path name and the new path name should be printed to
+standard error.
+</dd><dt>*-T* _filename_</dt><dd>
+In x or t mode,
+*tar*
+will read the list of names to be extracted from
+_filename_.
+In c mode,
+*tar*
+will read names to be archived from
+_filename_.
+The special name
+"-C"
+on a line by itself will cause the current directory to be changed to
+the directory specified on the following line.
+Names are terminated by newlines unless
+*--null*
+is specified.
+Note that
+*--null*
+also disables the special handling of lines containing
+"-C".
+</dd><dt>*-U*</dt><dd>
+(x mode only)
+Unlink files before creating them.
+Without this option,
+*tar*
+overwrites existing files, which preserves existing hardlinks.
+With this option, existing hardlinks will be broken, as will any
+symlink that would affect the location of an extracted file.
+</dd><dt>*--use-compress-program* _program_</dt><dd>
+Pipe the input (in x or t mode) or the output (in c mode) through
+_program_
+instead of using the builtin compression support.
+</dd><dt>*-v*</dt><dd>
+Produce verbose output.
+In create and extract modes,
+*tar*
+will list each file name as it is read from or written to
+the archive.
+In list mode,
+*tar*
+will produce output similar to that of
+*ls*(1).
+Additional
+*-v*
+options will provide additional detail.
+</dd><dt>*--version*</dt><dd>
+Print version of
+*tar*
+and
+*libarchive*,
+and exit.
+</dd><dt>*-w*</dt><dd>
+Ask for confirmation for every action.
+</dd><dt>*-X* _filename_</dt><dd>
+Read a list of exclusion patterns from the specified file.
+See
+*--exclude*
+for more information about the handling of exclusions.
+</dd><dt>*-y*</dt><dd>
+(c mode only)
+Compress the resulting archive with
+*bzip2*(1).
+In extract or list modes, this option is ignored.
+Note that, unlike other
+*tar*
+implementations, this implementation recognizes bzip2 compression
+automatically when reading archives.
+</dd><dt>*-z*</dt><dd>
+(c mode only)
+Compress the resulting archive with
+*gzip*(1).
+In extract or list modes, this option is ignored.
+Note that, unlike other
+*tar*
+implementations, this implementation recognizes gzip compression
+automatically when reading archives.
+</dd><dt>*-Z*</dt><dd>
+(c mode only)
+Compress the resulting archive with
+*compress*(1).
+In extract or list modes, this option is ignored.
+Note that, unlike other
+*tar*
+implementations, this implementation recognizes compress compression
+automatically when reading archives.
+</dd></dl>
+== ENVIRONMENT ==
+The following environment variables affect the execution of
+*tar*:
+<dl>
+<dt>*LANG*
+The locale to use.
+See
+*environ*(7)
+for more information.
+</dt><dt>*TAPE*
+The default tape device.
+The
+*-f*
+option overrides this.
+</dt><dt>*TZ*
+The timezone to use when displaying dates.
+See
+*environ*(7)
+for more information.
+</dt></dl>
+== FILES ==
+<dl>
+<dt>*/dev/sa0*
+The default tape device, if not overridden by the
+.IR TAPE
+environment variable or the
+*-f*
+option.
+</dt></dl>
+== EXIT STATUS ==
+The *tar* utility exits 0 on success, and >0 if an error occurs.
+== EXAMPLES ==
+The following creates a new archive
+called
+_file.tar.gz_
+that contains two files
+_source.c_
+and
+_source.h_:
+{{{
+tar -czf file.tar.gz source.c source.h
+}}}
+
+To view a detailed table of contents for this
+archive:
+{{{
+tar -tvf file.tar.gz
+}}}
+
+To extract all entries from the archive on
+the default tape drive:
+{{{
+tar -x
+}}}
+
+To examine the contents of an ISO 9660 cdrom image:
+{{{
+tar -tf image.iso
+}}}
+
+To move file hierarchies, invoke
+*tar*
+as
+{{{
+tar -cf - -C srcdir\. | tar -xpf - -C destdir
+}}}
+or more traditionally
+{{{
+cd srcdir ; tar -cf -\. | (cd destdir ; tar -xpf -)
+}}}
+
+In create mode, the list of files and directories to be archived
+can also include directory change instructions of the form
+*-C*_foo/baz_
+and archive inclusions of the form
+*@*_archive-file_.
+For example, the command line
+{{{
+tar -c -f new.tar foo1 @old.tgz -C/tmp foo2
+}}}
+will create a new archive
+_new.tar_.
+*tar*
+will read the file
+_foo1_
+from the current directory and add it to the output archive.
+It will then read each entry from
+_old.tgz_
+and add those entries to the output archive.
+Finally, it will switch to the
+_/tmp_
+directory and add
+_foo2_
+to the output archive.
+
+An input file in
+*mtree*(5)
+format can be used to create an output archive with arbitrary ownership,
+permissions, or names that differ from existing data on disk:
+
+{{{
+$ cat input.mtree
+}}}
+{{{
+#mtree
+}}}
+{{{
+usr/bin uid=0 gid=0 mode=0755 type=dir
+}}}
+{{{
+usr/bin/ls uid=0 gid=0 mode=0755 type=file content=myls
+}}}
+{{{
+$ tar -cvf output.tar @input.mtree
+}}}
+
+The
+*--newer*
+and
+*--newer-mtime*
+switches accept a variety of common date and time specifications, including
+"12 Mar 2005 7:14:29pm",
+"2005-03-12 19:14",
+"5 minutes ago",
+and
+"19:14 PST May 1".
+
+The
+*--options*
+argument can be used to control various details of archive generation
+or reading.
+For example, you can generate mtree output which only contains
+*type*, *time*,
+and
+*uid*
+keywords:
+{{{
+tar -cf file.tar --format=mtree --options='!all,type,time,uid' dir
+}}}
+or you can set the compression level used by gzip or xz compression:
+{{{
+tar -czf file.tar --options='compression-level=9'.
+}}}
+For more details, see the explanation of the
+*archive_read_set_options*()
+and
+*archive_write_set_options*()
+API calls that are described in
+*archive_read*(3)
+and
+*archive_write*(3).
+== COMPATIBILITY ==
+The bundled-arguments format is supported for compatibility
+with historic implementations.
+It consists of an initial word (with no leading - character) in which
+each character indicates an option.
+Arguments follow as separate words.
+The order of the arguments must match the order
+of the corresponding characters in the bundled command word.
+For example,
+{{{
+tar tbf 32 file.tar
+}}}
+specifies three flags
+*t*,
+*b*,
+and
+*f*.
+The
+*b*
+and
+*f*
+flags both require arguments,
+so there must be two additional items
+on the command line.
+The
+_32_
+is the argument to the
+*b*
+flag, and
+_file.tar_
+is the argument to the
+*f*
+flag.
+
+The mode options c, r, t, u, and x and the options
+b, f, l, m, o, v, and w comply with SUSv2.
+
+For maximum portability, scripts that invoke
+*tar*
+should use the bundled-argument format above, should limit
+themselves to the
+*c*,
+*t*,
+and
+*x*
+modes, and the
+*b*,
+*f*,
+*m*,
+*v*,
+and
+*w*
+options.
+
+Additional long options are provided to improve compatibility with other
+tar implementations.
+== SECURITY ==
+Certain security issues are common to many archiving programs, including
+*tar*.
+In particular, carefully-crafted archives can request that
+*tar*
+extract files to locations outside of the target directory.
+This can potentially be used to cause unwitting users to overwrite
+files they did not intend to overwrite.
+If the archive is being extracted by the superuser, any file
+on the system can potentially be overwritten.
+There are three ways this can happen.
+Although
+*tar*
+has mechanisms to protect against each one,
+savvy users should be aware of the implications:
+<ul>
+<li>
+Archive entries can have absolute pathnames.
+By default,
+*tar*
+removes the leading
+_/_
+character from filenames before restoring them to guard against this problem.
+</li><li>
+Archive entries can have pathnames that include
+_.._
+components.
+By default,
+*tar*
+will not extract files containing
+_.._
+components in their pathname.
+</li><li>
+Archive entries can exploit symbolic links to restore
+files to other directories.
+An archive can restore a symbolic link to another directory,
+then use that link to restore a file into that directory.
+To guard against this,
+*tar*
+checks each extracted path for symlinks.
+If the final path element is a symlink, it will be removed
+and replaced with the archive entry.
+If
+*-U*
+is specified, any intermediate symlink will also be unconditionally removed.
+If neither
+*-U*
+nor
+*-P*
+is specified,
+*tar*
+will refuse to extract the entry.
+</li></ul>
+To protect yourself, you should be wary of any archives that
+come from untrusted sources.
+You should examine the contents of an archive with
+{{{
+tar -tf filename
+}}}
+before extraction.
+You should use the
+*-k*
+option to ensure that
+*tar*
+will not overwrite any existing files or the
+*-U*
+option to remove any pre-existing files.
+You should generally not extract archives while running with super-user
+privileges.
+Note that the
+*-P*
+option to
+*tar*
+disables the security checks above and allows you to extract
+an archive while preserving any absolute pathnames,
+_.._
+components, or symlinks to other directories.

+== STANDARDS ==
+There is no current POSIX standard for the tar command; it appeared
+in
+ISO/IEC 9945-1:1996 (``POSIX.1'')
+but was dropped from
+IEEE Std 1003.1-2001 (``POSIX.1'').
+The options used by this implementation were developed by surveying a
+number of existing tar implementations as well as the old POSIX specification
+for tar and the current POSIX specification for pax.
+
+The ustar and pax interchange file formats are defined by
+IEEE Std 1003.1-2001 (``POSIX.1'')
+for the pax command.
+== HISTORY ==
+A
+*tar*
+command appeared in Seventh Edition Unix, which was released in January, 1979.
+There have been numerous other implementations,
+many of which extended the file format.
+John Gilmore's
+*pdtar*
+public-domain implementation (circa November, 1987)
+was quite influential, and formed the basis of GNU tar.
+GNU tar was included as the standard system tar
+in
+FreeBSD
+beginning with
+FreeBSD 1.0.
+
+This is a complete re-implementation based on the
+*libarchive*(3)
+library.
+== BUGS ==
+This program follows
+ISO/IEC 9945-1:1996 (``POSIX.1'')
+for the definition of the
+*-l*
+option.
+Note that GNU tar prior to version 1.15 treated
+*-l*
+as a synonym for the
+*--one-file-system*
+option.
+
+The
+*-C* _dir_
+option may differ from historic implementations.
+
+All archive output is written in correctly-sized blocks, even
+if the output is being compressed.
+Whether or not the last output block is padded to a full
+block size varies depending on the format and the
+output device.
+For tar and cpio formats, the last block of output is padded
+to a full block size if the output is being
+written to standard output or to a character or block device such as
+a tape drive.
+If the output is being written to a regular file, the last block
+will not be padded.
+Many compressors, including
+*gzip*(1)
+and
+*bzip2*(1),
+complain about the null padding when decompressing an archive created by
+*tar*,
+although they still extract it correctly.
+
+The compression and decompression is implemented internally, so
+there may be insignificant differences between the compressed output
+generated by
+{{{
+tar -czf - file
+}}}
+and that generated by
+{{{
+tar -cf - file | gzip
+}}}
+
+The default should be to read and write archives to the standard I/O paths,
+but tradition (and POSIX) dictates otherwise.
+
+The
+*r*
+and
+*u*
+modes require that the archive be uncompressed
+and located in a regular file on disk.
+Other archives can be modified using
+*c*
+mode with the
+_@archive-file_
+extension.
+
+To archive a file called
+_@foo_
+or
+_-foo_
+you must specify it as
+_./@foo_
+or
+_./-foo_,
+respectively.
+
+In create mode, a leading
+_./_
+is always removed.
+A leading
+_/_
+is stripped unless the
+*-P*
+option is specified.
+
+There needs to be better support for file selection on both create
+and extract.
+
+There is not yet any support for multi-volume archives or for archiving
+sparse files.
+
+Converting between dissimilar archive formats (such as tar and cpio) using the
+*@*_-_
+convention can cause hard link information to be lost.
+(This is a consequence of the incompatible ways that different archive
+formats store hardlink information.)
+
+There are alternative long options for many of the short options that
+are deliberately not documented.

+#summary CPIO 5 manual page
+== NAME ==
+*cpio*
+- format of cpio archive files
+== DESCRIPTION ==
+The
+*cpio*
+archive format collects any number of files, directories, and other
+file system objects (symbolic links, device nodes, etc.) into a single
+stream of bytes.
+=== General Format===
+Each file system object in a
+*cpio*
+archive comprises a header record with basic numeric metadata
+followed by the full pathname of the entry and the file data.
+The header record stores a series of integer values that generally
+follow the fields in
+_struct_ stat.
+(See
+*stat*(2)
+for details.)
+The variants differ primarily in how they store those integers
+(binary, octal, or hexadecimal).
+The header is followed by the pathname of the
+entry (the length of the pathname is stored in the header)
+and any file data.
+The end of the archive is indicated by a special record with
+the pathname
+"TRAILER!!!".
+=== PWB format===
+XXX Any documentation of the original PWB/UNIX 1.0 format? XXX
+=== Old Binary Format===
+The old binary
+*cpio*
+format stores numbers as 2-byte and 4-byte binary values.
+Each entry begins with a header in the following format:
+{{{
+struct header_old_cpio {
+        unsigned short   c_magic;
+        unsigned short   c_dev;
+        unsigned short   c_ino;
+        unsigned short   c_mode;
+        unsigned short   c_uid;
+        unsigned short   c_gid;
+        unsigned short   c_nlink;
+        unsigned short   c_rdev;
+       unsigned short   c_mtime[2];
+        unsigned short   c_namesize;
+       unsigned short   c_filesize[2];
+};
+}}}
+
+The
+_unsigned_ short
+fields here are 16-bit integer values; the
+_unsigned_ int
+fields are 32-bit integer values.
+The fields are as follows
+<dl>
+<dt>_magic_</dt><dd>
+The integer value octal 070707.
+This value can be used to determine whether this archive is
+written with little-endian or big-endian integers.
+</dd><dt>_dev_, _ino_</dt><dd>
+The device and inode numbers from the disk.
+These are used by programs that read
+*cpio*
+archives to determine when two entries refer to the same file.
+Programs that synthesize
+*cpio*
+archives should be careful to set these to distinct values for each entry.
+</dd><dt>_mode_</dt><dd>
+The mode specifies both the regular permissions and the file type.
+It consists of several bit fields as follows:
+<dl>
+<dt>0170000</dt><dd>
+This masks the file type bits.
+</dd><dt>0140000</dt><dd>
+File type value for sockets.
+</dd><dt>0120000</dt><dd>
+File type value for symbolic links.
+For symbolic links, the link body is stored as file data.
+</dd><dt>0100000</dt><dd>
+File type value for regular files.
+</dd><dt>0060000</dt><dd>
+File type value for block special devices.
+</dd><dt>0040000</dt><dd>
+File type value for directories.
+</dd><dt>0020000</dt><dd>
+File type value for character special devices.
+</dd><dt>0010000</dt><dd>
+File type value for named pipes or FIFOs.
+</dd><dt>0004000</dt><dd>
+SUID bit.
+</dd><dt>0002000</dt><dd>
+SGID bit.
+</dd><dt>0001000</dt><dd>
+Sticky bit.
+On some systems, this modifies the behavior of executables and/or directories.
+</dd><dt>0000777</dt><dd>
+The lower 9 bits specify read/write/execute permissions
+for world, group, and user following standard POSIX conventions.
+</dd></dl>
+</dd><dt>_uid_, _gid_</dt><dd>
+The numeric user id and group id of the owner.
+</dd><dt>_nlink_</dt><dd>
+The number of links to this file.
+Directories always have a value of at least two here.
+Note that hardlinked files include file data with every copy in the archive.
+</dd><dt>_rdev_</dt><dd>
+For block special and character special entries,
+this field contains the associated device number.
+For all other entry types, it should be set to zero by writers
+and ignored by readers.
+</dd><dt>_mtime_</dt><dd>
+Modification time of the file, indicated as the number
+of seconds since the start of the epoch,
+00:00:00 UTC January 1, 1970.
+The four-byte integer is stored with the most-significant 16 bits first
+followed by the least-significant 16 bits.
+Each of the two 16 bit values are stored in machine-native byte order.
+</dd><dt>_namesize_</dt><dd>
+The number of bytes in the pathname that follows the header.
+This count includes the trailing NUL byte.
+</dd><dt>_filesize_</dt><dd>
+The size of the file.
+Note that this archive format is limited to
+four gigabyte file sizes.
+See
+_mtime_
+above for a description of the storage of four-byte integers.
+</dd></dl>
+
+The pathname immediately follows the fixed header.
+If the
+*namesize*
+is odd, an additional NUL byte is added after the pathname.
+The file data is then appended, padded with NUL
+bytes to an even length.
+
+Hardlinked files are not given special treatment;
+the full file contents are included with each copy of the
+file.
+=== Portable ASCII Format===
+Version 2 of the Single UNIX Specification (``SUSv2'')
+standardized an ASCII variant that is portable across all
+platforms.
+It is commonly known as the
+"old character"
+format or as the
+"odc"
+format.
+It stores the same numeric fields as the old binary format, but
+represents them as 6-character or 11-character octal values.
+{{{
+struct cpio_odc_header {
+        char    c_magic[6];
+        char    c_dev[6];
+        char    c_ino[6];
+        char    c_mode[6];
+        char    c_uid[6];
+        char    c_gid[6];
+        char    c_nlink[6];
+        char    c_rdev[6];
+        char    c_mtime[11];
+        char    c_namesize[6];
+        char    c_filesize[11];
+};
+}}}
+
+The fields are identical to those in the old binary format.
+The name and file body follow the fixed header.
+Unlike the old binary format, there is no additional padding
+after the pathname or file contents.
+If the files being archived are themselves entirely ASCII, then
+the resulting archive will be entirely ASCII, except for the
+NUL byte that terminates the name field.
+=== New ASCII Format===
+The "new" ASCII format uses 8-byte hexadecimal fields for
+all numbers and separates device numbers into separate fields
+for major and minor numbers.
+{{{
+struct cpio_newc_header {
+        char    c_magic[6];
+        char    c_ino[8];
+        char    c_mode[8];
+        char    c_uid[8];
+        char    c_gid[8];
+        char    c_nlink[8];
+        char    c_mtime[8];
+        char    c_filesize[8];
+        char    c_devmajor[8];
+        char    c_devminor[8];
+        char    c_rdevmajor[8];
+        char    c_rdevminor[8];
+        char    c_namesize[8];
+        char    c_check[8];
+};
+}}}
+
+Except as specified below, the fields here match those specified
+for the old binary format above.
+<dl>
+<dt>_magic_</dt><dd>
+The string
+"070701".
+</dd><dt>_check_</dt><dd>
+This field is always set to zero by writers and ignored by readers.
+See the next section for more details.
+</dd></dl>
+
+The pathname is followed by NUL bytes so that the total size
+of the fixed header plus pathname is a multiple of four.
+Likewise, the file data is padded to a multiple of four bytes.
+Note that this format supports only 4 gigabyte files (unlike the
+older ASCII format, which supports 8 gigabyte files).
+
+In this format, hardlinked files are handled by setting the
+filesize to zero for each entry except the last one that
+appears in the archive.
+=== New CRC Format===
+The CRC format is identical to the new ASCII format described
+in the previous section except that the magic field is set
+to
+"070702"
+and the
+_check_
+field is set to the sum of all bytes in the file data.
+This sum is computed treating all bytes as unsigned values
+and using unsigned arithmetic.
+Only the least-significant 32 bits of the sum are stored.
+=== HP variants===
+The
+*cpio*
+implementation distributed with HPUX used XXXX but stored
+device numbers differently XXX.
+=== Other Extensions and Variants===
+Sun Solaris uses additional file types to store extended file
+data, including ACLs and extended attributes, as special
+entries in cpio archives.
+
+XXX Others? XXX
+== BUGS ==
+The
+"CRC"
+format is mis-named, as it uses a simple checksum and
+not a cyclic redundancy check.
+
+The old binary format is limited to 16 bits for user id,
+group id, device, and inode numbers.
+It is limited to 4 gigabyte file sizes.
+
+The old ASCII format is limited to 18 bits for
+the user id, group id, device, and inode numbers.
+It is limited to 8 gigabyte file sizes.
+
+The new ASCII format is limited to 4 gigabyte file sizes.
+
+None of the cpio formats store user or group names,
+which are essential when moving files between systems with
+dissimilar user or group numbering.
+
+Especially when writing older cpio variants, it may be necessary
+to map actual device/inode values to synthesized values that
+fit the available fields.
+With very large filesystems, this may be necessary even for
+the newer formats.
+== SEE ALSO ==
+*cpio*(1),
+*tar*(5)
+== STANDARDS ==
+The
+*cpio*
+utility is no longer a part of POSIX or the Single Unix Standard.
+It last appeared in
+Version 2 of the Single UNIX Specification (``SUSv2'').
+It has been supplanted in subsequent standards by
+*pax*(1).
+The portable ASCII format is currently part of the specification for the
+*pax*(1)
+utility.
+== HISTORY ==
+The original cpio utility was written by Dick Haight
+while working in AT&T's Unix Support Group.
+It appeared in 1977 as part of PWB/UNIX 1.0, the
+"Programmer's Work Bench"
+derived from
+At v6
+that was used internally at AT&T.
+Both the old binary and old character formats were in use
+by 1980, according to the System III source released
+by SCO under their
+"Ancient Unix"
+license.
+The character format was adopted as part of
+IEEE Std 1003.1-1988 (``POSIX.1'').

+#summary LIBARCHIVE 3 manual page
+== NAME ==
+*libarchive*
+- functions for reading and writing streaming archives
+== LIBRARY ==
+Lb libarchive
+== OVERVIEW ==
+The
+*libarchive*
+library provides a flexible interface for reading and writing
+streaming archive files such as tar and cpio.
+The library is inherently stream-oriented; readers serially iterate through
+the archive, writers serially add things to the archive.
+In particular, note that there is no built-in support for
+random access nor for in-place modification.
+
+When reading an archive, the library automatically detects the
+format and the compression.
+The library currently has read support for:
+<ul>
+<li>
+old-style tar archives,
+</li><li>
+most variants of the POSIX
+"ustar"
+format,
+</li><li>
+the POSIX
+"pax interchange"
+format,
+</li><li>
+GNU-format tar archives,
+</li><li>
+most common cpio archive formats,
+</li><li>
+ISO9660 CD images (with or without RockRidge extensions),
+</li><li>
+Zip archives.
+</li></ul>
+The library automatically detects archives compressed with
+*gzip*(1),
+*bzip2*(1),
+or
+*compress*(1)
+and decompresses them transparently.
+
+When writing an archive, you can specify the compression
+to be used and the format to use.
+The library can write
+<ul>
+<li>
+POSIX-standard
+"ustar"
+archives,
+</li><li>
+POSIX
+"pax interchange format"
+archives,
+</li><li>
+POSIX octet-oriented cpio archives,
+</li><li>
+two different variants of shar archives.
+</li></ul>
+Pax interchange format is an extension of the tar archive format that
+eliminates essentially all of the limitations of historic tar formats
+in a standard fashion that is supported
+by POSIX-compliant
+*pax*(1)
+implementations on many systems as well as several newer implementations of
+*tar*(1).
+Note that the default write format will suppress the pax extended
+attributes for most entries; explicitly requesting pax format will
+enable those attributes for all entries.
+
+The read and write APIs are accessed through the
+*archive_read_XXX*()
+functions and the
+*archive_write_XXX*()
+functions, respectively, and either can be used independently
+of the other.
+
+The rest of this manual page provides an overview of the library
+operation.
+More detailed information can be found in the individual manual
+pages for each API or utility function.
+== READING AN ARCHIVE ==
+To read an archive, you must first obtain an initialized
+*struct archive*
+object from
+*archive_read_new*().
+You can then modify this object for the desired operations with the
+various
+*archive_read_set_XXX*()
+and
+*archive_read_support_XXX*()
+functions.
+In particular, you will need to invoke appropriate
+*archive_read_support_XXX*()
+functions to enable the corresponding compression and format
+support.
+Note that these latter functions perform two distinct operations:
+they cause the corresponding support code to be linked into your
+program, and they enable the corresponding auto-detect code.
+Unless you have specific constraints, you will generally want
+to invoke
+*archive_read_support_compression_all*()
+and
+*archive_read_support_format_all*()
+to enable auto-detect for all formats and compression types
+currently supported by the library.
+
+Once you have prepared the
+*struct archive*
+object, you call
+*archive_read_open*()
+to actually open the archive and prepare it for reading.
+There are several variants of this function;
+the most basic expects you to provide pointers to several
+functions that can provide blocks of bytes from the archive.
+There are convenience forms that allow you to
+specify a filename, file descriptor,
+*FILE `*`*
+object, or a block of memory from which to read the archive data.
+Note that the core library makes no assumptions about the
+size of the blocks read;
+callback functions are free to read whatever block size is
+most appropriate for the medium.
+
+Each archive entry consists of a header followed by a certain
+amount of data.
+You can obtain the next header with
+*archive_read_next_header*(),
+which returns a pointer to an
+*struct archive_entry*
+structure with information about the current archive element.
+If the entry is a regular file, then the header will be followed
+by the file data.
+You can use
+*archive_read_data*()
+(which works much like the
+*read*(2)
+system call)
+to read this data from the archive.
+You may prefer to use the higher-level
+*archive_read_data_skip*(),
+which reads and discards the data for this entry,
+*archive_read_data_to_buffer*(),
+which reads the data into an in-memory buffer,
+*archive_read_data_to_file*(),
+which copies the data to the provided file descriptor, or
+*archive_read_extract*(),
+which recreates the specified entry on disk and copies data
+from the archive.
+In particular, note that
+*archive_read_extract*()
+uses the
+*struct archive_entry*
+structure that you provide it, which may differ from the
+entry just read from the archive.
+In particular, many applications will want to override the
+pathname, file permissions, or ownership.
+
+Once you have finished reading data from the archive, you
+should call
+*archive_read_close*()
+to close the archive, then call
+*archive_read_finish*()
+to release all resources, including all memory allocated by the library.
+
+The
+*archive_read*(3)
+manual page provides more detailed calling information for this API.
+== WRITING AN ARCHIVE ==
+You use a similar process to write an archive.
+The
+*archive_write_new*()
+function creates an archive object useful for writing,
+the various
+*archive_write_set_XXX*()
+functions are used to set parameters for writing the archive, and
+*archive_write_open*()
+completes the setup and opens the archive for writing.
+
+Individual archive entries are written in a three-step
+process:
+You first initialize a
+*struct archive_entry*
+structure with information about the new entry.
+At a minimum, you should set the pathname of the
+entry and provide a
+_struct_ stat
+with a valid
+_st_mode_
+field, which specifies the type of object and
+_st_size_
+field, which specifies the size of the data portion of the object.
+The
+*archive_write_header*()
+function actually writes the header data to the archive.
+You can then use
+*archive_write_data*()
+to write the actual data.
+
+After all entries have been written, use the
+*archive_write_finish*()
+function to release all resources.
+
+The
+*archive_write*(3)
+manual page provides more detailed calling information for this API.
+== DESCRIPTION ==
+Detailed descriptions of each function are provided by the
+corresponding manual pages.
+
+All of the functions utilize an opaque
+*struct archive*
+datatype that provides access to the archive contents.
+
+The
+*struct archive_entry*
+structure contains a complete description of a single archive
+entry.
+It uses an opaque interface that is fully documented in
+*archive_entry*(3).
+
+Users familiar with historic formats should be aware that the newer
+variants have eliminated most restrictions on the length of textual fields.
+Clients should not assume that filenames, link names, user names, or
+group names are limited in length.
+In particular, pax interchange format can easily accommodate pathnames
+in arbitrary character sets that exceed
+_PATH_MAX_.
+== RETURN VALUES ==
+Most functions return zero on success, non-zero on error.
+The return value indicates the general severity of the error, ranging
+from
+*ARCHIVE_WARN*,
+which indicates a minor problem that should probably be reported
+to the user, to
+*ARCHIVE_FATAL*,
+which indicates a serious problem that will prevent any further
+operations on this archive.
+On error, the
+*archive_errno*()
+function can be used to retrieve a numeric error code (see
+*errno*(2)).
+The
+*archive_error_string*()
+returns a textual error message suitable for display.
+
+*archive_read_new*()
+and
+*archive_write_new*()
+return pointers to an allocated and initialized
+*struct archive*
+object.
+
+*archive_read_data*()
+and
+*archive_write_data*()
+return a count of the number of bytes actually read or written.
+A value of zero indicates the end of the data for this entry.
+A negative value indicates an error, in which case the
+*archive_errno*()
+and
+*archive_error_string*()
+functions can be used to obtain more information.
+== ENVIRONMENT ==
+There are character set conversions within the
+*archive_entry*(3)
+functions that are impacted by the currently-selected locale.
+== SEE ALSO ==
+*tar*(1),
+*archive_entry*(3),
+*archive_read*(3),
+*archive_util*(3),
+*archive_write*(3),
+*tar*(5)
+== HISTORY ==
+The
+*libarchive*
+library first appeared in
+FreeBSD 5.3.
+== AUTHORS ==
+The
+*libarchive*
+library was written by
+Tim Kientzle  <kientzle@acm.org.>
+== BUGS ==
+Some archive formats support information that is not supported by
+*struct archive_entry .*
+Such information cannot be fully archived or restored using this library.
+This includes, for example, comments, character sets,
+or the arbitrary key/value pairs that can appear in
+pax interchange format archives.
+
+Conversely, of course, not all of the information that can be
+stored in an
+*struct archive_entry*
+is supported by all formats.
+For example, cpio formats do not support nanosecond timestamps;
+old tar formats do not support large device numbers.

+== NAME ==
+*libarchive-formats*
+- archive formats supported by the libarchive library
+== DESCRIPTION ==
+The
+*libarchive*(3)
+library reads and writes a variety of streaming archive formats.
+Generally speaking, all of these archive formats consist of a series of
+"entries".
+Each entry stores a single file system object, such as a file, directory,
+or symbolic link.
+
+The following provides a brief description of each format supported
+by libarchive, with some information about recognized extensions or
+limitations of the current library support.
+Note that just because a format is supported by libarchive does not
+imply that a program that uses libarchive will support that format.
+Applications that use libarchive specify which formats they wish
+to support, though many programs do use libarchive convenience
+functions to enable all supported formats.
+=== Tar Formats===
+The
+*libarchive*(3)
+library can read most tar archives.
+However, it only writes POSIX-standard
+"ustar"
+and
+"pax interchange"
+formats.
+
+All tar formats store each entry in one or more 512-byte records.
+The first record is used for file metadata, including filename,
+timestamp, and mode information, and the file data is stored in
+subsequent records.
+Later variants have extended this by either appropriating undefined
+areas of the header record, extending the header to multiple records,
+or by storing special entries that modify the interpretation of
+subsequent entries.
+
+<dl>
+<dt>*gnutar*</dt><dd>
+The
+*libarchive*(3)
+library can read GNU-format tar archives.
+It currently supports the most popular GNU extensions, including
+modern long filename and linkname support, as well as atime and ctime data.
+The libarchive library does not support multi-volume
+archives, nor the old GNU long filename format.
+It can read GNU sparse file entries, including the new POSIX-based
+formats, but cannot write GNU sparse file entries.
+</dd><dt>*pax*</dt><dd>
+The
+*libarchive*(3)
+library can read and write POSIX-compliant pax interchange format
+archives.
+Pax interchange format archives are an extension of the older ustar
+format that adds a separate entry with additional attributes stored
+as key/value pairs immediately before each regular entry.
+The presence of these additional entries is the only difference between
+pax interchange format and the older ustar format.
+The extended attributes are of unlimited length and are stored
+as UTF-8 Unicode strings.
+Keywords defined in the standard are in all lowercase; vendors are allowed
+to define custom keys by preceding them with the vendor name in all uppercase.
+When writing pax archives, libarchive uses many of the SCHILY keys
+defined by Joerg Schilling's
+"star"
+archiver and a few LIBARCHIVE keys.
+The libarchive library can read most of the SCHILY keys
+and most of the GNU keys introduced by GNU tar.
+It silently ignores any keywords that it does not understand.
+</dd><dt>*restricted* pax</dt><dd>
+The libarchive library can also write pax archives in which it
+attempts to suppress the extended attributes entry whenever
+possible.
+The result will be identical to a ustar archive unless the
+extended attributes entry is required to store a long file
+name, long linkname, extended ACL, file flags, or if any of the standard
+ustar data (user name, group name, UID, GID, etc) cannot be fully
+represented in the ustar header.
+In all cases, the result can be dearchived by any program that
+can read POSIX-compliant pax interchange format archives.
+Programs that correctly read ustar format (see below) will also be
+able to read this format; any extended attributes will be extracted as
+separate files stored in
+_PaxHeader_
+directories.
+</dd><dt>*ustar*</dt><dd>
+The libarchive library can both read and write this format.
+This format has the following limitations:
+<ul>
+<li>
+Device major and minor numbers are limited to 21 bits.
+Nodes with larger numbers will not be added to the archive.
+</li><li>
+Path names in the archive are limited to 255 bytes.
+(Shorter if there is no / character in exactly the right place.)
+</li><li>
+Symbolic links and hard links are stored in the archive with
+the name of the referenced file.
+This name is limited to 100 bytes.
+</li><li>
+Extended attributes, file flags, and other extended
+security information cannot be stored.
+</li><li>
+Archive entries are limited to 8 gigabytes in size.
+</li></ul>
+Note that the pax interchange format has none of these restrictions.
+</dd></dl>
+
+The libarchive library also reads a variety of commonly-used extensions to
+the basic tar format.
+These extensions are recognized automatically whenever they appear.
+<dl>
+<dt>Numeric extensions.</dt><dd>
+The POSIX standards require fixed-length numeric fields to be written with
+some character position reserved for terminators.
+Libarchive allows these fields to be written without terminator characters.
+This extends the allowable range; in particular, ustar archives with this
+extension can support entries up to 64 gigabytes in size.
+Libarchive also recognizes base-256 values in most numeric fields.
+This essentially removes all limitations on file size, modification time,
+and device numbers.
+</dd><dt>Solaris extensions</dt><dd>
+Libarchive recognizes ACL and extended attribute records written
+by Solaris tar.
+Currently, libarchive only has support for old-style ACLs; the
+newer NFSv4 ACLs are recognized but discarded.
+</dd></dl>
+
+The first tar program appeared in Seventh Edition Unix in 1979.
+The first official standard for the tar file format was the
+"ustar"
+(Unix Standard Tar) format defined by POSIX in 1988.
+POSIX.1-2001 extended the ustar format to create the
+"pax interchange"
+format.
+=== Cpio Formats===
+The libarchive library can read a number of common cpio variants and can write
+"odc"
+and
+"newc"
+format archives.
+A cpio archive stores each entry as a fixed-size header followed
+by a variable-length filename and variable-length data.
+Unlike the tar format, the cpio format does only minimal padding
+of the header or file data.
+There are several cpio variants, which differ primarily in
+how they store the initial header: some store the values as
+octal or hexadecimal numbers in ASCII, others as binary values of
+varying byte order and length.
+<dl>
+<dt>*binary*</dt><dd>
+The libarchive library transparently reads both big-endian and little-endian
+variants of the original binary cpio format.
+This format used 32-bit binary values for file size and mtime,
+and 16-bit binary values for the other fields.
+</dd><dt>*odc*</dt><dd>
+The libarchive library can both read and write this
+POSIX-standard format, which is officially known as the
+"cpio interchange format"
+or the
+"octet-oriented cpio archive format"
+and sometimes unofficially referred to as the
+"old character format".
+This format stores the header contents as octal values in ASCII.
+It is standard, portable, and immune from byte-order confusion.
+File sizes and mtime are limited to 33 bits (8GB file size),
+other fields are limited to 18 bits.
+</dd><dt>*SVR4*</dt><dd>
+The libarchive library can read both CRC and non-CRC variants of
+this format.
+The SVR4 format uses eight-digit hexadecimal values for
+all header fields.
+This limits file size to 4GB, and also limits the mtime and
+other fields to 32 bits.
+The SVR4 format can optionally include a CRC of the file
+contents, although libarchive does not currently verify this CRC.
+</dd></dl>
+
+Cpio first appeared in PWB/UNIX 1.0, which was released within
+AT&T in 1977.
+PWB/UNIX 1.0 formed the basis of System III Unix, released outside
+of AT&T in 1981.
+This makes cpio older than tar, although cpio was not included
+in Version 7 AT&T Unix.
+As a result, the tar command became much better known in universities
+and research groups that used Version 7.
+The combination of the
+*find*
+and
+*cpio*
+utilities provided very precise control over file selection.
+Unfortunately, the format has many limitations that make it unsuitable
+for widespread use.
+Only the POSIX format permits files over 4GB, and its 18-bit
+limit for most other fields makes it unsuitable for modern systems.
+In addition, cpio formats only store numeric UID/GID values (not
+usernames and group names), which can make it very difficult to correctly
+transfer archives across systems with dissimilar user numbering.
+=== Shar Formats===
+A
+"shell archive"
+is a shell script that, when executed on a POSIX-compliant
+system, will recreate a collection of file system objects.
+The libarchive library can write two different kinds of shar archives:
+<dl>
+<dt>*shar*</dt><dd>
+The traditional shar format uses a limited set of POSIX
+commands, including
+*echo*(1),
+*mkdir*(1),
+and
+*sed*(1).
+It is suitable for portably archiving small collections of plain text files.
+However, it is not generally well-suited for large archives
+(many implementations of
+*sh*(1)
+have limits on the size of a script) nor should it be used with non-text files.
+</dd><dt>*shardump*</dt><dd>
+This format is similar to shar but encodes files using
+*uuencode*(1)
+so that the result will be a plain text file regardless of the file contents.
+It also includes additional shell commands that attempt to reproduce as
+many file attributes as possible, including owner, mode, and flags.
+The additional commands used to restore file attributes make
+shardump archives less portable than plain shar archives.
+</dd></dl>
+=== ISO9660 format===
+Libarchive can read and extract from files containing ISO9660-compliant
+CDROM images.
+In many cases, this can remove the need to burn a physical CDROM
+just in order to read the files contained in an ISO9660 image.
+It also avoids security and complexity issues that come with
+virtual mounts and loopback devices.
+Libarchive supports the most common Rockridge extensions and has partial
+support for Joliet extensions.
+If both extensions are present, the Joliet extensions will be
+used and the Rockridge extensions will be ignored.
+In particular, this can create problems with hardlinks and symlinks,
+which are supported by Rockridge but not by Joliet.
+=== Zip format===
+Libarchive can read and write zip format archives that have
+uncompressed entries and entries compressed with the
+"deflate"
+algorithm.
+Older zip compression algorithms are not supported.
+It can extract jar archives, archives that use Zip64 extensions and many
+self-extracting zip archives.
+Libarchive reads Zip archives as they are being streamed,
+which allows it to read archives of arbitrary size.
+It currently does not use the central directory; this
+limits libarchive's ability to support some self-extracting
+archives and ones that have been modified in certain ways.
+=== Archive (library) file format===
+The Unix archive format (commonly created by the
+*ar*(1)
+archiver) is a general-purpose format which is
+used almost exclusively for object files to be
+read by the link editor
+*ld*(1).
+The ar format has never been standardised.
+There are two common variants:
+the GNU format derived from SVR4,
+and the BSD format, which first appeared in 4.4BSD.
+The two differ primarily in their handling of filenames
+longer than 15 characters:
+the GNU/SVR4 variant writes a filename table at the beginning of the archive;
+the BSD format stores each long filename in an extension
+area adjacent to the entry.
+Libarchive can read both extensions,
+including archives that may include both types of long filenames.
+Programs using libarchive can write GNU/SVR4 format
+if they provide a filename table to be written into
+the archive before any of the entries.
+Any entries whose names are not in the filename table
+will be written using BSD-style long filenames.
+This can cause problems for programs such as
+GNU ld that do not support the BSD-style long filenames.
+=== mtree===
+Libarchive can read and write files in
+*mtree*(5)
+format.
+This format is not a true archive format, but rather a textual description
+of a file hierarchy in which each line specifies the name of a file and
+provides specific metadata about that file.
+Libarchive can read all of the keywords supported by both
+the NetBSD and FreeBSD versions of
+*mtree*(1),
+although many of the keywords cannot currently be stored in an
+*archive_entry*
+object.
+When writing, libarchive supports use of the
+*archive_write_set_options*(3)
+interface to specify which keywords should be included in the
+output.
+If libarchive was compiled with access to suitable
+cryptographic libraries (such as the OpenSSL libraries),
+it can compute hash entries such as
+*sha512*
+or
+*md5*
+from file data being written to the mtree writer.
+
+When reading an mtree file, libarchive will locate the corresponding
+files on disk using the
+*contents*
+keyword if present or the regular filename.
+If it can locate and open the file on disk, it will use that
+to fill in any metadata that is missing from the mtree file
+and will read the file contents and return those to the program
+using libarchive.
+If it cannot locate and open the file on disk, libarchive
+will return an error for any attempt to read the entry
+body.

+#summary LIBARCHIVE 3 manual page
+== NAME ==
+*libarchive_internals*
+- description of libarchive internal interfaces
+== OVERVIEW ==
+The
+*libarchive*
+library provides a flexible interface for reading and writing
+streaming archive files such as tar and cpio.
+Internally, it follows a modular layered design that should
+make it easy to add new archive and compression formats.
+== GENERAL ARCHITECTURE ==
+Externally, libarchive exposes most operations through an
+opaque, object-style interface.
+The
+*archive_entry*(1)
+objects store information about a single filesystem object.
+The rest of the library provides facilities to write
+*archive_entry*(1)
+objects to archive files,
+read them from archive files,
+and write them to disk.
+(There are plans to add a facility to read
+*archive_entry*(1)
+objects from disk as well.)
+
+The read and write APIs each have four layers: a public API
+layer, a format layer that understands the archive file format,
+a compression layer, and an I/O layer.
+The I/O layer is completely exposed to clients who can replace
+it entirely with their own functions.
+
+In order to provide as much consistency as possible for clients,
+some public functions are virtualized.
+Eventually, it should be possible for clients to open
+an archive or disk writer, and then use a single set of
+code to select and write entries, regardless of the target.
+== READ ARCHITECTURE ==
+From the outside, clients use the
+*archive_read*(3)
+API to manipulate an
+*archive*
+object to read entries and bodies from an archive stream.
+Internally, the
+*archive*
+object is cast to an
+*archive_read*
+object, which holds all read-specific data.
+The API has four layers:
+The lowest layer is the I/O layer.
+This layer can be overridden by clients, but most clients use
+the packaged I/O callbacks provided, for example, by
+*archive_read_open_memory*(3),
+and
+*archive_read_open_fd*(3).
+The compression layer calls the I/O layer to
+read bytes and decompresses them for the format layer.
+The format layer unpacks a stream of uncompressed bytes and
+creates
+*archive_entry*
+objects from the incoming data.
+The API layer tracks overall state
+(for example, it prevents clients from reading data before reading a header)
+and invokes the format and compression layer operations
+through registered function pointers.
+In particular, the API layer drives the format-detection process:
+When opening the archive, it reads an initial block of data
+and offers it to each registered compression handler.
+The one with the highest bid is initialized with the first block.
+Similarly, the format handlers are polled to see which handler
+is the best for each archive.
+(Prior to 2.4.0, the format bidders were invoked for each
+entry, but this design hindered error recovery.)
+=== I/O Layer and Client Callbacks===
+The read API goes to some lengths to be nice to clients.
+As a result, there are few restrictions on the behavior of
+the client callbacks.
+
+The client read callback is expected to provide a block
+of data on each call.
+A zero-length return does indicate end of file, but otherwise
+blocks may be as small as one byte or as large as the entire file.
+In particular, blocks may be of different sizes.
+
+The client skip callback returns the number of bytes actually
+skipped, which may be much smaller than the skip requested.
+The only requirement is that the skip not be larger.
+In particular, clients are allowed to return zero for any
+skip that they don't want to handle.
+The skip callback must never be invoked with a negative value.
+
+Keep in mind that not all clients are reading from disk:
+clients reading from networks may provide different-sized
+blocks on every request and cannot skip at all;
+advanced clients may use
+*mmap*(2)
+to read the entire file into memory at once and return the
+entire file to libarchive as a single block;
+other clients may begin asynchronous I/O operations for the
+next block on each request.
+=== Decompresssion Layer===
+The decompression layer not only handles decompression,
+it also buffers data so that the format handlers see a
+much nicer I/O model.
+The decompression API is a two stage peek/consume model.
+A read_ahead request specifies a minimum read amount;
+the decompression layer must provide a pointer to at least
+that much data.
+If more data is immediately available, it should return more:
+the format layer handles bulk data reads by asking for a minimum
+of one byte and then copying as much data as is available.
+
+A subsequent call to the
+*consume*()
+function advances the read pointer.
+Note that data returned from a
+*read_ahead*()
+call is guaranteed to remain in place until
+the next call to
+*read_ahead*().
+Intervening calls to
+*consume*()
+should not cause the data to move.
+
+Skip requests must always be handled exactly.
+Decompression handlers that cannot seek forward should
+not register a skip handler;
+the API layer fills in a generic skip handler that reads and discards data.
+
+A decompression handler has a specific lifecycle:
+<dl>
+<dt>Registration/Configuration</dt><dd>
+When the client invokes the public support function,
+the decompression handler invokes the internal
+*__archive_read_register_compression*()
+function to provide bid and initialization functions.
+This function returns
+*NULL*
+on error or else a pointer to a
+*struct* decompressor_t.
+This structure contains a
+_void_ * config
+slot that can be used for storing any customization information.
+</dd><dt>Bid</dt><dd>
+The bid function is invoked with a pointer and size of a block of data.
+The decompressor can access its config data
+through the
+_decompressor_
+element of the
+*archive_read*
+object.
+The bid function is otherwise stateless.
+In particular, it must not perform any I/O operations.
+
+The value returned by the bid function indicates its suitability
+for handling this data stream.
+A bid of zero will ensure that this decompressor is never invoked.
+Return zero if magic number checks fail.
+Otherwise, your initial implementation should return the number of bits
+actually checked.
+For example, if you verify two full bytes and three bits of another
+byte, bid 19.
+Note that the initial block may be very short;
+be careful to only inspect the data you are given.
+(The current decompressors require two bytes for correct bidding.)
+</dd><dt>Initialize</dt><dd>
+The winning bidder will have its init function called.
+This function should initialize the remaining slots of the
+_struct_ decompressor_t
+object pointed to by the
+_decompressor_
+element of the
+_archive_read_
+object.
+In particular, it should allocate any working data it needs
+in the
+_data_
+slot of that structure.
+The init function is called with the block of data that
+was used for tasting.
+At this point, the decompressor is responsible for all I/O
+requests to the client callbacks.
+The decompressor is free to read more data as and when
+necessary.
+</dd><dt>Satisfy I/O requests</dt><dd>
+The format handler will invoke the
+_read_ahead_,
+_consume_,
+and
+_skip_
+functions as needed.
+</dd><dt>Finish</dt><dd>
+The finish method is called only once when the archive is closed.
+It should release anything stored in the
+_data_
+and
+_config_
+slots of the
+_decompressor_
+object.
+It should not invoke the client close callback.
+</dd></dl>
+=== Format Layer===
+The read formats have a similar lifecycle to the decompression handlers:
+<dl>
+<dt>Registration</dt><dd>
+Allocate your private data and initialize your pointers.
+</dd><dt>Bid</dt><dd>
+Formats bid by invoking the
+*read_ahead*()
+decompression method but not calling the
+*consume*()
+method.
+This allows each bidder to look ahead in the input stream.
+Bidders should not look further ahead than necessary, as long
+look aheads put pressure on the decompression layer to buffer
+lots of data.
+Most formats only require a few hundred bytes of look ahead;
+look aheads of a few kilobytes are reasonable.
+(The ISO9660 reader sometimes looks ahead by 48k, which
+should be considered an upper limit.)
+</dd><dt>Read header</dt><dd>
+The header read is usually the most complex part of any format.
+There are a few strategies worth mentioning:
+For formats such as tar or cpio, reading and parsing the header is
+straightforward since headers alternate with data.
+For formats that store all header data at the beginning of the file,
+the first header read request may have to read all headers into
+memory and store that data, sorted by the location of the file
+data.
+Subsequent header read requests will skip forward to the
+beginning of the file data and return the corresponding header.
+</dd><dt>Read Data</dt><dd>
+The read data interface supports sparse files; this requires that
+each call return a block of data specifying the file offset and
+size.
+This may require you to carefully track the location so that you
+can return accurate file offsets for each read.
+Remember that the decompressor will return as much data as it has.
+Generally, you will want to request one byte,
+examine the return value to see how much data is available, and
+possibly trim that to the amount you can use.
+You should invoke consume for each block just before you return it.
+</dd><dt>Skip All Data</dt><dd>
+The skip data call should skip over all file data and trailing padding.
+This is called automatically by the API layer just before each
+header read.
+It is also called in response to the client calling the public
+*data_skip*()
+function.
+</dd><dt>Cleanup</dt><dd>
+On cleanup, the format should release all of its allocated memory.
+</dd></dl>
+=== API Layer===
+XXX to do XXX
+== WRITE ARCHITECTURE ==
+The write API has a similar set of four layers:
+an API layer, a format layer, a compression layer, and an I/O layer.
+The registration here is much simpler because only
+one format and one compression can be registered at a time.
+=== I/O Layer and Client Callbacks===
+XXX To be written XXX
+=== Compression Layer===
+XXX To be written XXX
+=== Format Layer===
+XXX To be written XXX
+=== API Layer===
+XXX To be written XXX
+== WRITE_DISK ARCHITECTURE ==
+The write_disk API is intended to look just like the write API
+to clients.
+Since it does not handle multiple formats or compression, it
+is not layered internally.
+== GENERAL SERVICES ==
+The
+*archive_read*,
+*archive_write*,
+and
+*archive_write_disk*
+objects all contain an initial
+*archive*
+object which provides common support for a set of standard services.
+(Recall that ANSI/ISO C90 guarantees that you can cast freely between
+a pointer to a structure and a pointer to the first element of that
+structure.)
+The
+*archive*
+object has a magic value that indicates which API this object
+is associated with,
+slots for storing error information,
+and function pointers for virtualized API functions.
+== MISCELLANEOUS NOTES ==
+Connecting existing archiving libraries into libarchive is generally
+quite difficult.
+In particular, many existing libraries strongly assume that you
+are reading from a file; they seek forwards and backwards as necessary
+to locate various pieces of information.
+In contrast, libarchive never seeks backwards in its input, which
+sometimes requires very different approaches.
+
+For example, libarchive's ISO9660 support operates very differently
+from most ISO9660 readers.
+The libarchive support utilizes a work-queue design that
+keeps a list of known entries sorted by their location in the input.
+Whenever libarchive's ISO9660 implementation is asked for the next
+header, checks this list to find the next item on the disk.
+Directories are parsed when they are encountered and new
+items are added to the list.
+This design relies heavily on the ISO9660 image being optimized so that
+directories always occur earlier on the disk than the files they
+describe.
+
+Depending on the specific format, such approaches may not be possible.
+The ZIP format specification, for example, allows archivers to store
+key information only at the end of the file.
+In theory, it is possible to create ZIP archives that cannot
+be read without seeking.
+Fortunately, such archives are very rare, and libarchive can read
+most ZIP archives, though it cannot always extract as much information
+as a dedicated ZIP program.

+#summary MTREE 5 manual page
+== NAME ==
+*mtree*
+- format of mtree dir hierarchy files
+== DESCRIPTION ==
+The
+*mtree*
+format is a textual format that describes a collection of filesystem objects.
+Such files are typically used to create or verify directory hierarchies.
+=== General Format===
+An
+*mtree*
+file consists of a series of lines, each providing information
+about a single filesystem object.
+Leading whitespace is always ignored.
+
+When encoding file or pathnames, any backslash character or
+character outside of the 95 printable ASCII characters must be
+encoded as a a backslash followed by three
+octal digits.
+When reading mtree files, any appearance of a backslash
+followed by three octal digits should be converted into the
+corresponding character.
+
+Each line is interpreted independently as one of the following types:
+<dl>
+<dt>Signature</dt><dd>
+The first line of any mtree file must begin with
+"#mtree".
+If a file contains any full path entries, the first line should
+begin with
+"#mtree v2.0",
+otherwise, the first line should begin with
+"#mtree v1.0".
+</dd><dt>Blank</dt><dd>
+Blank lines are ignored.
+</dd><dt>Comment</dt><dd>
+Lines beginning with
+*#*
+are ignored.
+</dd><dt>Special</dt><dd>
+Lines beginning with
+*/*
+are special commands that influence
+the interpretation of later lines.
+</dd><dt>Relative</dt><dd>
+If the first whitespace-delimited word has no
+*/*
+characters,
+it is the name of a file in the current directory.
+Any relative entry that describes a directory changes the
+current directory.
+</dd><dt>dot-dot</dt><dd>
+As a special case, a relative entry with the filename
+_.._
+changes the current directory to the parent directory.
+Options on dot-dot entries are always ignored.
+</dd><dt>Full</dt><dd>
+If the first whitespace-delimited word has a
+*/*
+character after
+the first character, it is the pathname of a file relative to the
+starting directory.
+There can be multiple full entries describing the same file.
+</dd></dl>
+
+Some tools that process
+*mtree*
+files may require that multiple lines describing the same file
+occur consecutively.
+It is not permitted for the same file to be mentioned using
+both a relative and a full file specification.
+=== Special commands===
+Two special commands are currently defined:
+<dl>
+<dt>*/set*</dt><dd>
+This command defines default values for one or more keywords.
+It is followed on the same line by one or more whitespace-separated
+keyword definitions.
+These definitions apply to all following files that do not specify
+a value for that keyword.
+</dd><dt>*/unset*</dt><dd>
+This command removes any default value set by a previous
+*/set*
+command.
+It is followed on the same line by one or more keywords
+separated by whitespace.
+</dd></dl>
+=== Keywords===
+After the filename, a full or relative entry consists of zero
+or more whitespace-separated keyword definitions.
+Each such definition consists of a key from the following
+list immediately followed by an '=' sign
+and a value.
+Software programs reading mtree files should warn about
+unrecognized keywords.
+
+Currently supported keywords are as follows:
+<dl>
+<dt>*cksum*</dt><dd>
+The checksum of the file using the default algorithm specified by
+the
+*cksum*(1)
+utility.
+</dd><dt>*contents*</dt><dd>
+The full pathname of a file that holds the contents of this file.
+</dd><dt>*flags*</dt><dd>
+The file flags as a symbolic name.
+See
+*chflags*(1)
+for information on these names.
+If no flags are to be set the string
+"none"
+may be used to override the current default.
+</dd><dt>*gid*</dt><dd>
+The file group as a numeric value.

+== NAME ==
+*tar*
+- format of tape archive files
+== DESCRIPTION ==
+The
+*tar*
+archive format collects any number of files, directories, and other
+file system objects (symbolic links, device nodes, etc.) into a single
+stream of bytes.
+The format was originally designed to be used with
+tape drives that operate with fixed-size blocks, but is widely used as
+a general packaging mechanism.
+=== General Format===
+A
+*tar*
+archive consists of a series of 512-byte records.
+Each file system object requires a header record which stores basic metadata
+(pathname, owner, permissions, etc.) and zero or more records containing any
+file data.
+The end of the archive is indicated by two records consisting
+entirely of zero bytes.
+
+For compatibility with tape drives that use fixed block sizes,
+programs that read or write tar files always read or write a fixed
+number of records with each I/O operation.
+These
+"blocks"
+are always a multiple of the record size.
+The maximum block size supported by early
+implementations was 10240 bytes or 20 records.
+This is still the default for most implementations
+although block sizes of 1MiB (2048 records) or larger are
+commonly used with modern high-speed tape drives.
+(Note: the terms
+"block"
+and
+"record"
+here are not entirely standard; this document follows the
+convention established by John Gilmore in documenting
+*pdtar*.)
+=== Old-Style Archive Format===
+The original tar archive format has been extended many times to
+include additional information that various implementors found
+necessary.
+This section describes the variant implemented by the tar command
+included in
+At v7,
+which seems to be the earliest widely-used version of the tar program.
+
+The header record for an old-style
+*tar*
+archive consists of the following:
+{{{
+struct header_old_tar {
+       char name[100];
+       char mode[8];
+       char uid[8];
+       char gid[8];
+       char size[12];
+       char mtime[12];
+       char checksum[8];
+       char linkflag[1];
+       char linkname[100];
+       char pad[255];
+};
+}}}
+All unused bytes in the header record are filled with nulls.
+<dl>
+<dt>_name_</dt><dd>
+Pathname, stored as a null-terminated string.
+Early tar implementations only stored regular files (including
+hardlinks to those files).
+One common early convention used a trailing "/" character to indicate
+a directory name, allowing directory permissions and owner information
+to be archived and restored.
+</dd><dt>_mode_</dt><dd>
+File mode, stored as an octal number in ASCII.
+</dd><dt>_uid_, _gid_</dt><dd>
+User id and group id of owner, as octal numbers in ASCII.
+</dd><dt>_size_</dt><dd>
+Size of file, as octal number in ASCII.
+For regular files only, this indicates the amount of data
+that follows the header.
+In particular, this field was ignored by early tar implementations
+when extracting hardlinks.
+Modern writers should always store a zero length for hardlink entries.
+</dd><dt>_mtime_</dt><dd>
+Modification time of file, as an octal number in ASCII.
+This indicates the number of seconds since the start of the epoch,
+00:00:00 UTC January 1, 1970.
+Note that negative values should be avoided
+here, as they are handled inconsistently.
+</dd><dt>_checksum_</dt><dd>
+Header checksum, stored as an octal number in ASCII.
+To compute the checksum, set the checksum field to all spaces,
+then sum all bytes in the header using unsigned arithmetic.
+This field should be stored as six octal digits followed by a null and a space
+character.
+Note that many early implementations of tar used signed arithmetic
+for the checksum field, which can cause interoperability problems
+when transferring archives between systems.
+Modern robust readers compute the checksum both ways and accept the
+header if either computation matches.
+</dd><dt>_linkflag_, _linkname_</dt><dd>
+In order to preserve hardlinks and conserve tape, a file
+with multiple links is only written to the archive the first
+time it is encountered.
+The next time it is encountered, the
+_linkflag_
+is set to an ASCII
+Sq 1
+and the
+_linkname_
+field holds the first name under which this file appears.
+(Note that regular files have a null value in the
+_linkflag_
+field.)
+</dd></dl>
+
+Early tar implementations varied in how they terminated these fields.
+The tar command in
+At v7
+used the following conventions (this is also documented in early BSD manpages):
+the pathname must be null-terminated;
+the mode, uid, and gid fields must end in a space and a null byte;
+the size and mtime fields must end in a space;
+the checksum is terminated by a null and a space.
+Early implementations filled the numeric fields with leading spaces.
+This seems to have been common practice until the
+IEEE Std 1003.1-1988 (``POSIX.1'')
+standard was released.
+For best portability, modern implementations should fill the numeric
+fields with leading zeros.
+=== Pre-POSIX Archives===
+An early draft of
+IEEE Std 1003.1-1988 (``POSIX.1'')
+served as the basis for John Gilmore's
+*pdtar*
+program and many system implementations from the late 1980s
+and early 1990s.
+These archives generally follow the POSIX ustar
+format described below with the following variations:
+<ul>
+<li>
+The magic value is
+"ustar\ \&"
+(note the following space).
+The version field contains a space character followed by a null.
+</li><li>
+The numeric fields are generally filled with leading spaces
+(not leading zeros as recommended in the final standard).
+</li><li>
+The prefix field is often not used, limiting pathnames to
+the 100 characters of old-style archives.
+</li></ul>
+=== POSIX ustar Archives===
+IEEE Std 1003.1-1988 (``POSIX.1'')
+defined a standard tar file format to be read and written
+by compliant implementations of
+*tar*(1).
+This format is often called the
+"ustar"
+format, after the magic value used
+in the header.
+(The name is an acronym for
+"Unix Standard TAR".)
+It extends the historic format with new fields:
+{{{
+struct header_posix_ustar {
+       char name[100];
+       char mode[8];
+       char uid[8];
+       char gid[8];
+       char size[12];
+       char mtime[12];
+       char checksum[8];
+       char typeflag[1];
+       char linkname[100];
+       char magic[6];
+       char version[2];
+       char uname[32];
+       char gname[32];
+       char devmajor[8];
+       char devminor[8];
+       char prefix[155];
+       char pad[12];
+};
+}}}
+<dl>
+<dt>_typeflag_</dt><dd>
+Type of entry.
+POSIX extended the earlier
+_linkflag_
+field with several new type values:
+<dl>
+<dt>"0"</dt><dd>
+Regular file.
+NUL should be treated as a synonym, for compatibility purposes.
+</dd><dt>"1"</dt><dd>
+Hard link.
+</dd><dt>"2"</dt><dd>
+Symbolic link.
+</dd><dt>"3"</dt><dd>
+Character device node.
+</dd><dt>"4"</dt><dd>
+Block device node.
+</dd><dt>"5"</dt><dd>
+Directory.
+</dd><dt>"6"</dt><dd>
+FIFO node.
+</dd><dt>"7"</dt><dd>
+Reserved.
+</dd><dt>Other</dt><dd>
+A POSIX-compliant implementation must treat any unrecognized typeflag value
+as a regular file.
+In particular, writers should ensure that all entries
+have a valid filename so that they can be restored by readers that do not
+support the corresponding extension.
+Uppercase letters "A" through "Z" are reserved for custom extensions.
+Note that sockets and whiteout entries are not archivable.
+</dd></dl>
+It is worth noting that the
+_size_
+field, in particular, has different meanings depending on the type.
+For regular files, of course, it indicates the amount of data
+following the header.
+For directories, it may be used to indicate the total size of all
+files in the directory, for use by operating systems that pre-allocate
+directory space.
+For all other types, it should be set to zero by writers and ignored
+by readers.
+</dd><dt>_magic_</dt><dd>
+Contains the magic value
+"ustar"
+followed by a NUL byte to indicate that this is a POSIX standard archive.
+Full compliance requires the uname and gname fields be properly set.
+</dd><dt>_version_</dt><dd>
+Version.
+This should be
+"00"
+(two copies of the ASCII digit zero) for POSIX standard archives.
+</dd><dt>_uname_, _gname_</dt><dd>
+User and group names, as null-terminated ASCII strings.
+These should be used in preference to the uid/gid values
+when they are set and the corresponding names exist on
+the system.
+</dd><dt>_devmajor_, _devminor_</dt><dd>
+Major and minor numbers for character device or block device entry.
+</dd><dt>_name_, _prefix_</dt><dd>
+If the pathname is too long to fit in the 100 bytes provided by the standard
+format, it can be split at any
+_/_
+character with the first portion going into the prefix field.
+If the prefix field is not empty, the reader will prepend
+the prefix value and a
+_/_
+character to the regular name field to obtain the full pathname.
+The standard does not require a trailing
+_/_
+character on directory names, though most implementations still
+include this for compatibility reasons.
+</dd></dl>
+
+Note that all unused bytes must be set to
+NUL.
+
+Field termination is specified slightly differently by POSIX
+than by previous implementations.
+The
+_magic_,
+_uname_,
+and
+_gname_
+fields must have a trailing
+NUL.
+The
+_pathname_,
+_linkname_,
+and
+_prefix_
+fields must have a trailing
+NUL
+unless they fill the entire field.
+(In particular, it is possible to store a 256-character pathname if it
+happens to have a
+_/_
+as the 156th character.)
+POSIX requires numeric fields to be zero-padded in the front, and requires
+them to be terminated with either space or
+NUL
+characters.
+
+Currently, most tar implementations comply with the ustar
+format, occasionally extending it by adding new fields to the
+blank area at the end of the header record.
+=== Pax Interchange Format===
+There are many attributes that cannot be portably stored in a
+POSIX ustar archive.
+IEEE Std 1003.1-2001 (``POSIX.1'')
+defined a
+"pax interchange format"
+that uses two new types of entries to hold text-formatted
+metadata that applies to following entries.
+Note that a pax interchange format archive is a ustar archive in every
+respect.
+The new data is stored in ustar-compatible archive entries that use the
+"x"
+or
+"g"
+typeflag.
+In particular, older implementations that do not fully support these
+extensions will extract the metadata into regular files, where the
+metadata can be examined as necessary.
+
+An entry in a pax interchange format archive consists of one or
+two standard ustar entries, each with its own header and data.
+The first optional entry stores the extended attributes
+for the following entry.
+This optional first entry has an "x" typeflag and a size field that
+indicates the total size of the extended attributes.
+The extended attributes themselves are stored as a series of text-format
+lines encoded in the portable UTF-8 encoding.
+Each line consists of a decimal number, a space, a key string, an equals
+sign, a value string, and a new line.
+The decimal number indicates the length of the entire line, including the
+initial length field and the trailing newline.
+An example of such a field is:
+{{{
+25 ctime=1084839148.1212\en
+}}}
+Keys in all lowercase are standard keys.
+Vendors can add their own keys by prefixing them with an all uppercase
+vendor name and a period.
+Note that, unlike the historic header, numeric values are stored using
+decimal, not octal.
+A description of some common keys follows:
+<dl>
+<dt>*atime*, *ctime*, *mtime*</dt><dd>
+File access, inode change, and modification times.
+These fields can be negative or include a decimal point and a fractional value.
+</dd><dt>*uname*, *uid*, *gname*, *gid*</dt><dd>
+User name, group name, and numeric UID and GID values.
+The user name and group name stored here are encoded in UTF8
+and can thus include non-ASCII characters.
+The UID and GID fields can be of arbitrary length.
+</dd><dt>*linkpath*</dt><dd>
+The full path of the linked-to file.
+Note that this is encoded in UTF8 and can thus include non-ASCII characters.
+</dd><dt>*path*</dt><dd>
+The full pathname of the entry.
+Note that this is encoded in UTF8 and can thus include non-ASCII characters.
+</dd><dt>*realtime.`*`*, *security.`*`*</dt><dd>
+These keys are reserved and may be used for future standardization.
+</dd><dt>*size*</dt><dd>
+The size of the file.
+Note that there is no length limit on this field, allowing conforming
+archives to store files much larger than the historic 8GB limit.
+</dd><dt>*SCHILY.`*`*</dt><dd>
+Vendor-specific attributes used by Joerg Schilling's
+*star*
+implementation.
+</dd><dt>*SCHILY.acl.access*, *SCHILY.acl.default*</dt><dd>
+Stores the access and default ACLs as textual strings in a format
+that is an extension of the format specified by POSIX.1e draft 17.
+In particular, each user or group access specification can include a fourth
+colon-separated field with the numeric UID or GID.
+This allows ACLs to be restored on systems that may not have complete
+user or group information available (such as when NIS/YP or LDAP services
+are temporarily unavailable).
+</dd><dt>*SCHILY.devminor*, *SCHILY.devmajor*</dt><dd>
+The full minor and major numbers for device nodes.
+</dd><dt>*SCHILY.fflags*</dt><dd>
+The file flags.
+</dd><dt>*SCHILY.realsize*</dt><dd>
+The full size of the file on disk.
+XXX explain? XXX
+</dd><dt>*SCHILY.dev,* *SCHILY.ino*, *SCHILY.nlinks*</dt><dd>
+The device number, inode number, and link count for the entry.
+In particular, note that a pax interchange format archive using Joerg
+Schilling's
+*SCHILY.`*`*
+extensions can store all of the data from
+_struct_ stat.
+</dd><dt>*LIBARCHIVE.xattr.*_namespace_._key_</dt><dd>
+Libarchive stores POSIX.1e-style extended attributes using
+keys of this form.
+The
+_key_
+value is URL-encoded:
+All non-ASCII characters and the two special characters
+"="
+and
+"%"
+are encoded as
+"%"
+followed by two uppercase hexadecimal digits.
+The value of this key is the extended attribute value
+encoded in base 64.
+XXX Detail the base-64 format here XXX
+</dd><dt>*VENDOR.`*`*</dt><dd>
+XXX document other vendor-specific extensions XXX
+</dd></dl>
+
+Any values stored in an extended attribute override the corresponding
+values in the regular tar header.
+Note that compliant readers should ignore the regular fields when they
+are overridden.
+This is important, as existing archivers are known to store non-compliant
+values in the standard header fields in this situation.
+There are no limits on length for any of these fields.
+In particular, numeric fields can be arbitrarily large.
+All text fields are encoded in UTF8.
+Compliant writers should store only portable 7-bit ASCII characters in
+the standard ustar header and use extended
+attributes whenever a text value contains non-ASCII characters.
+
+In addition to the
+*x*
+entry described above, the pax interchange format
+also supports a
+*g*
+entry.
+The
+*g*
+entry is identical in format, but specifies attributes that serve as
+defaults for all subsequent archive entries.
+The
+*g*
+entry is not widely used.
+
+Besides the new
+*x*
+and
+*g*
+entries, the pax interchange format has a few other minor variations
+from the earlier ustar format.
+The most troubling one is that hardlinks are permitted to have
+data following them.
+This allows readers to restore any hardlink to a file without
+having to rewind the archive to find an earlier entry.
+However, it creates complications for robust readers, as it is no longer
+clear whether or not they should ignore the size field for hardlink entries.
+=== GNU Tar Archives===
+The GNU tar program started with a pre-POSIX format similar to that
+described earlier and has extended it using several different mechanisms:
+It added new fields to the empty space in the header (some of which was later
+used by POSIX for conflicting purposes);
+it allowed the header to be continued over multiple records;
+and it defined new entries that modify following entries
+(similar in principle to the
+*x*
+entry described above, but each GNU special entry is single-purpose,
+unlike the general-purpose
+*x*
+entry).
+As a result, GNU tar archives are not POSIX compatible, although
+more lenient POSIX-compliant readers can successfully extract most
+GNU tar archives.

+<dl>
+<dt>_typeflag_</dt><dd>
+GNU tar uses the following special entry types, in addition to
+those defined by POSIX:
+<dl>
+<dt>7</dt><dd>
+GNU tar treats type "7" records identically to type "0" records,
+except on one obscure RTOS where they are used to indicate the
+pre-allocation of a contiguous file on disk.
+</dd><dt>D</dt><dd>
+This indicates a directory entry.
+Unlike the POSIX-standard "5"
+typeflag, the header is followed by data records listing the names
+of files in this directory.
+Each name is preceded by an ASCII "Y"
+if the file is stored in this archive or "N" if the file is not
+stored in this archive.
+Each name is terminated with a null, and
+an extra null marks the end of the name list.
+The purpose of this
+entry is to support incremental backups; a program restoring from
+such an archive may wish to delete files on disk that did not exist
+in the directory when the archive was made.
+
+Note that the "D" typeflag specifically violates POSIX, which requires
+that unrecognized typeflags be restored as normal files.
+In this case, restoring the "D" entry as a file could interfere
+with subsequent creation of the like-named directory.
+</dd><dt>K</dt><dd>
+The data for this entry is a long linkname for the following regular entry.
+</dd><dt>L</dt><dd>
+The data for this entry is a long pathname for the following regular entry.
+</dd><dt>M</dt><dd>
+This is a continuation of the last file on the previous volume.
+GNU multi-volume archives guarantee that each volume begins with a valid
+entry header.
+To ensure this, a file may be split, with part stored at the end of one volume,
+and part stored at the beginning of the next volume.
+The "M" typeflag indicates that this entry continues an existing file.
+Such entries can only occur as the first or second entry
+in an archive (the latter only if the first entry is a volume label).
+The
+_size_
+field specifies the size of this entry.
+The
+_offset_
+field at bytes 369-380 specifies the offset where this file fragment
+begins.
+The
+_realsize_
+field specifies the total size of the file (which must equal
+_size_
+plus
+_offset_).
+When extracting, GNU tar checks that the header file name is the one it is
+expecting, that the header offset is in the correct sequence, and that
+the sum of offset and size is equal to realsize.
+</dd><dt>N</dt><dd>
+Type "N" records are no longer generated by GNU tar.
+They contained a
+list of files to be renamed or symlinked after extraction; this was
+originally used to support long names.
+The contents of this record
+are a text description of the operations to be done, in the form
+"Rename %s to %s\en"
+or
+"Symlink %s to %s\en ;"
+in either case, both
+filenames are escaped using K&R C syntax.
+Due to security concerns, "N" records are now generally ignored
+when reading archives.
+</dd><dt>S</dt><dd>
+This is a
+"sparse"
+regular file.
+Sparse files are stored as a series of fragments.
+The header contains a list of fragment offset/length pairs.
+If more than four such entries are required, the header is
+extended as necessary with
+"extra"
+header extensions (an older format that is no longer used), or
+"sparse"
+extensions.
+</dd><dt>V</dt><dd>
+The
+_name_
+field should be interpreted as a tape/volume header name.
+This entry should generally be ignored on extraction.
+</dd></dl>
+</dd><dt>_magic_</dt><dd>
+The magic field holds the five characters
+"ustar"
+followed by a space.
+Note that POSIX ustar archives have a trailing null.
+</dd><dt>_version_</dt><dd>
+The version field holds a space character followed by a null.
+Note that POSIX ustar archives use two copies of the ASCII digit
+"0".
+</dd><dt>_atime_, _ctime_</dt><dd>
+The time the file was last accessed and the time of
+last change of file information, stored in octal as with
+_mtime_.
+</dd><dt>_longnames_</dt><dd>
+This field is apparently no longer used.
+</dd><dt>Sparse _offset_ / _numbytes_</dt><dd>
+Each such structure specifies a single fragment of a sparse
+file.
+The two fields store values as octal numbers.
+The fragments are each padded to a multiple of 512 bytes
+in the archive.
+On extraction, the list of fragments is collected from the
+header (including any extension headers), and the data
+is then read and written to the file at appropriate offsets.
+</dd><dt>_isextended_</dt><dd>
+If this is set to non-zero, the header will be followed by additional
+"sparse header"
+records.
+Each such record contains information about as many as 21 additional
+sparse blocks as shown here:
+{{{
+struct gnu_sparse_header {
+       struct {
+               char offset[12];
+               char numbytes[12];
+       } sparse[21];
+       char    isextended[1];
+       char    padding[7];
+};
+}}}
+</dd><dt>_realsize_</dt><dd>
+A binary representation of the file's complete size, with a much larger range
+than the POSIX file size.
+In particular, with
+*M*
+type files, the current entry is only a portion of the file.
+In that case, the POSIX size field will indicate the size of this
+entry; the
+_realsize_
+field will indicate the total size of the file.
+</dd></dl>
+=== GNU tar pax archives===
+GNU tar 1.14 (XXX check this XXX) and later will write
+pax interchange format archives when you specify the
+*--posix*
+flag.
+This format uses custom keywords to store sparse file information.
+There have been three iterations of this support, referred to
+as
+"0.0",
+"0.1",
+and
+"1.0".
+<dl>
+<dt>*GNU.sparse.numblocks*, *GNU.sparse.offset*, *GNU.sparse.numbytes*, *GNU.sparse.size*</dt><dd>
+The
+"0.0"
+format used an initial
+*GNU.sparse.numblocks*
+attribute to indicate the number of blocks in the file, a pair of
+*GNU.sparse.offset*
+and
+*GNU.sparse.numbytes*
+to indicate the offset and size of each block,
+and a single
+*GNU.sparse.size*
+to indicate the full size of the file.
+This is not the same as the size in the tar header because the
+latter value does not include the size of any holes.
+This format required that the order of attributes be preserved and
+relied on readers accepting multiple appearances of the same attribute
+names, which is not officially permitted by the standards.
+</dd><dt>*GNU.sparse.map*</dt><dd>
+The
+"0.1"
+format used a single attribute that stored a comma-separated
+list of decimal numbers.
+Each pair of numbers indicated the offset and size, respectively,
+of a block of data.
+This does not work well if the archive is extracted by an archiver
+that does not recognize this extension, since many pax implementations
+simply discard unrecognized attributes.
+</dd><dt>*GNU.sparse.major*, *GNU.sparse.minor*, *GNU.sparse.name*, *GNU.sparse.realsize*</dt><dd>
+The
+"1.0"
+format stores the sparse block map in one or more 512-byte blocks
+prepended to the file data in the entry body.
+The pax attributes indicate the existence of this map
+(via the
+*GNU.sparse.major*
+and
+*GNU.sparse.minor*
+fields)
+and the full size of the file.
+The
+*GNU.sparse.name*
+holds the true name of the file.
+To avoid confusion, the name stored in the regular tar header
+is a modified name so that extraction errors will be apparent
+to users.
+</dd></dl>
+=== Solaris Tar===
+XXX More Details Needed XXX
+
+Solaris tar (beginning with SunOS XXX 5.7 ?? XXX) supports an
+"extended"
+format that is fundamentally similar to pax interchange format,
+with the following differences:
+<ul>
+<li>
+Extended attributes are stored in an entry whose type is
+*X*,
+not
+*x*,
+as used by pax interchange format.
+The detailed format of this entry appears to be the same
+as detailed above for the
+*x*
+entry.
+</li><li>
+An additional
+*A*
+entry is used to store an ACL for the following regular entry.
+The body of this entry contains a seven-digit octal number
+followed by a zero byte, followed by the
+textual ACL description.
+The octal value is the number of ACL entries
+plus a constant that indicates the ACL type: 01000000
+for POSIX.1e ACLs and 03000000 for NFSv4 ACLs.
+</li></ul>
+=== AIX Tar===
+XXX More details needed XXX
+=== Mac OS X Tar===
+The tar distributed with Apple's Mac OS X stores most regular files
+as two separate entries in the tar archive.
+The two entries have the same name except that the first
+one has
+"._"
+added to the beginning of the name.
+This first entry stores the
+"resource fork"
+with additional attributes for the file.
+The Mac OS X
+*CopyFile*()
+API is used to separate a file on disk into separate
+resource and data streams and to reassemble those separate
+streams when the file is restored to disk.
+=== Other Extensions===
+One obvious extension to increase the size of files is to
+eliminate the terminating characters from the various
+numeric fields.
+For example, the standard only allows the size field to contain
+11 octal digits, reserving the twelfth byte for a trailing
+NUL character.
+Allowing 12 octal digits allows file sizes up to 64 GB.
+
+Another extension, utilized by GNU tar, star, and other newer
+*tar*
+implementations, permits binary numbers in the standard numeric fields.
+This is flagged by setting the high bit of the first byte.
+This permits 95-bit values for the length and time fields
+and 63-bit values for the uid, gid, and device numbers.
+GNU tar supports this extension for the
+length, mtime, ctime, and atime fields.
+Joerg Schilling's star program supports this extension for
+all numeric fields.
+Note that this extension is largely obsoleted by the extended attribute
+record provided by the pax interchange format.
+
+Another early GNU extension allowed base-64 values rather than octal.
+This extension was short-lived and is no longer supported by any
+implementation.
+== SEE ALSO ==
+*ar*(1),
+*pax*(1),
+*tar*(1)
+== STANDARDS ==
+The
+*tar*
+utility is no longer a part of POSIX or the Single Unix Standard.
+It last appeared in
+Version 2 of the Single UNIX Specification (``SUSv2'').
+It has been supplanted in subsequent standards by
+*pax*(1).
+The ustar format is currently part of the specification for the
+*pax*(1)
+utility.
+The pax interchange file format is new with
+IEEE Std 1003.1-2001 (``POSIX.1'').
+== HISTORY ==
+A
+*tar*
+command appeared in Seventh Edition Unix, which was released in January, 1979.
+It replaced the
+*tp*
+program from Fourth Edition Unix which in turn replaced the
+*tap*
+program from First Edition Unix.
+John Gilmore's
+*pdtar*
+public-domain implementation (circa 1987) was highly influential
+and formed the basis of
+*GNU* tar
+(circa 1988).
+Joerg Shilling's
+*star*
+archiver is another open-source (GPL) archiver (originally developed
+circa 1985) which features complete support for pax interchange
+format.
+
+This documentation was written as part of the
+*libarchive*
+and
+*bsdtar*
+project by

+"minitar" is a minimal example of a program that uses libarchive to
+read/write various archive formats.  It's a more ambitious version of
+'untar.c' that includes compile-time options to enable/disable various
+features, including non-tar formats, archive creation, and automatic
+decompression support.
+
+I use this as a test bed to check for "link pollution," ensuring that
+a program using libarchive does not pull in unnecessary code.
+
+The "minitar" program is also a good starting point for anyone who
+wants to use libarchive for their own purposes, as it demonstrates
+basic usage of the library.

+ * This is a compact "tar" program whose primary goal is small size.
+ * Statically linked, it can be very small indeed.  This serves a number
+ * of goals:
+ *   o a testbed for libarchive (to check for link pollution),
+ *   o a useful tool for space-constrained systems (boot floppies, etc),
+ *   o a place to experiment with new implementation ideas for bsdtar,
+ *   o a small program to demonstrate libarchive usage.
+ *
+ * Use the following macros to suppress features:
+ *   NO_BZIP2 - Implies NO_BZIP2_CREATE and NO_BZIP2_EXTRACT
+ *   NO_BZIP2_CREATE - Suppress bzip2 compression support.
+ *   NO_BZIP2_EXTRACT - Suppress bzip2 auto-detection and decompression.
+ *   NO_COMPRESS - Implies NO_COMPRESS_CREATE and NO_COMPRESS_EXTRACT
+ *   NO_COMPRESS_CREATE - Suppress compress(1) compression support
+ *   NO_COMPRESS_EXTRACT - Suppress compress(1) auto-detect and decompression.
+ *   NO_CREATE - Suppress all archive creation support.
+ *   NO_CPIO_EXTRACT - Suppress auto-detect and dearchiving of cpio archives.
+ *   NO_GZIP - Implies NO_GZIP_CREATE and NO_GZIP_EXTRACT
+ *   NO_GZIP_CREATE - Suppress gzip compression support.
+ *   NO_GZIP_EXTRACT - Suppress gzip auto-detection and decompression.
+ *   NO_LOOKUP - Try to avoid getpw/getgr routines, which can be very large
+ *   NO_TAR_EXTRACT - Suppress tar extraction
+ *
+ * With all of the above macros defined (except NO_TAR_EXTRACT), you
+ * get a very small program that can recognize and extract essentially
+ * any uncompressed tar archive.  On FreeBSD 5.1, this minimal program
+ * is under 64k, statically linked, which compares rather favorably to
+ *         main(){printf("hello, world");}
+ * which is over 60k statically linked on the same operating system.
+ * Without any of the above macros, you get a static executable of
+ * about 180k with a lot of very sophisticated modern features.
+ * Obviously, it's trivial to add support for ISO, Zip, mtree,
+ * lzma/xz, etc.  Just fill in the appropriate setup calls.

+ * This is a compact tar extraction program using libarchive whose
+ * primary goal is small executable size.  Statically linked, it can
+ * be very small, depending in large part on how cleanly factored your
+ * system libraries are.  Note that this uses the standard libarchive,
+ * without any special recompilation.  The only functional concession
+ * is that this program uses the uid/gid from the archive instead of
+ * doing uname/gname lookups.  (Add a call to
+ * archive_write_disk_set_standard_lookup() to enable uname/gname
+ * lookups, but be aware that this can add 500k or more to a static
+ * executable, depending on the system libraries, since user/group
+ * lookups frequently pull in password, YP/LDAP, networking, and DNS
+ * resolver libraries.)
+ *
+ * To build:
+ * $ gcc -static -Wall -o untar untar.c -larchive
+ * $ strip untar
+ *
+ * NOTE: On some systems, you may need to add additional flags
+ * to ensure that untar.c is compiled the same way as libarchive
+ * was compiled.  In particular, Linux users will probably
+ * have to add -D_FILE_OFFSET_BITS=64 to the command line above.
+ *
+ * For fun, statically compile the following simple hello.c program
+ * using the same flags as for untar and compare the size:
+ *
+ * #include <stdio.h>
+ * int main(int argc, char **argv) {
+ *    printf("hello, world\n");
+ *    return(0);
+ * }
+ *
+ * You may be even more surprised by the compiled size of true.c listed here:
+ *
+ * int main(int argc, char **argv) {
+ *    return (0);
+ * }
+ *
+ * On a slightly customized FreeBSD 5 system that I used around
+ * 2005, hello above compiled to 89k compared to untar of 69k.  So at
+ * that time, libarchive's tar reader and extract-to-disk routines
+ * compiled to less code than printf().
+ *
+ * On my FreeBSD development system today (August, 2009):
+ *  hello: 195024 bytes
+ *  true: 194912 bytes
+ *  untar: 259924 bytes

+.Sh DESCRIPTION
+These functions create and manipulate data objects that
+represent entries within an archive.
+You can think of a
+.Tn struct archive_entry
+as a heavy-duty version of
+.Tn struct stat :
+it includes everything from
+.Tn struct stat
+plus associated pathname, textual group and user names, etc.
+These objects are used by
+.Xr libarchive 3
+to represent the metadata associated with a particular
+entry in an archive.
+.Ss Create and Destroy
+There are functions to allocate, destroy, clear, and copy
+.Va archive_entry
+objects:
+.Bl -tag -compact -width indent
+.It Fn archive_entry_clear
+Erases the object, resetting all internal fields to the
+same state as a newly-created object.
+This is provided to allow you to quickly recycle objects
+without thrashing the heap.
+.It Fn archive_entry_clone
+A deep copy operation; all text fields are duplicated.
+.It Fn archive_entry_free
+Releases the
+.Tn struct archive_entry
+object.
+.It Fn archive_entry_new
+Allocate and return a blank
+.Tn struct archive_entry
+object.
+.El
+.Ss Set and Get Functions
+Most of the functions here set or read entries in an object.
+Such functions have one of the following forms:
+.Bl -tag -compact -width indent
+.It Fn archive_entry_set_XXXX
+Stores the provided data in the object.
+In particular, for strings, the pointer is stored,
+not the referenced string.
+.It Fn archive_entry_copy_XXXX
+As above, except that the referenced data is copied
+into the object.
+.It Fn archive_entry_XXXX
+Returns the specified data.
+In the case of strings, a const-qualified pointer to
+the string is returned.
+.El
+String data can be set or accessed as wide character strings
+or normal
+.Va char
+strings.
+The functions that use wide character strings are suffixed with
+.Cm _w .
+Note that these are different representations of the same data:
+For example, if you store a narrow string and read the corresponding
+wide string, the object will transparently convert formats
+using the current locale.
+Similarly, if you store a wide string and then store a
+narrow string for the same data, the previously-set wide string will
+be discarded in favor of the new data.
+.Pp
+There are a few set/get functions that merit additional description:
+.Bl -tag -compact -width indent
+.It Fn archive_entry_set_link
+This function sets the symlink field if it is already set.
+Otherwise, it sets the hardlink field.
+.El
+.Ss File Flags
+File flags are transparently converted between a bitmap
+representation and a textual format.
+For example, if you set the bitmap and ask for text, the library
+will build a canonical text format.
+However, if you set a text format and request a text format,
+you will get back the same text, even if it is ill-formed.
+If you need to canonicalize a textual flags string, you should first set the
+text form, then request the bitmap form, then use that to set the bitmap form.
+Setting the bitmap format will clear the internal text representation
+and force it to be reconstructed when you next request the text form.
+.Pp
+The bitmap format consists of two integers, one containing bits
+that should be set, the other specifying bits that should be
+cleared.
+Bits not mentioned in either bitmap will be ignored.
+Usually, the bitmap of bits to be cleared will be set to zero.
+In unusual circumstances, you can force a fully-specified set
+of file flags by setting the bitmap of flags to clear to the complement
+of the bitmap of flags to set.
+(This differs from
+.Xr fflagstostr 3 ,
+which only includes names for set bits.)
+Converting a bitmap to a textual string is a platform-specific
+operation; bits that are not meaningful on the current platform
+will be ignored.
+.Pp
+The canonical text format is a comma-separated list of flag names.
+The
+.Fn archive_entry_copy_fflags_text
+and
+.Fn archive_entry_copy_fflags_text_w
+functions parse the provided text and sets the internal bitmap values.
+This is a platform-specific operation; names that are not meaningful
+on the current platform will be ignored.
+The function returns a pointer to the start of the first name that was not
+recognized, or NULL if every name was recognized.
+Note that every name--including names that follow an unrecognized name--will
+be evaluated, and the bitmaps will be set to reflect every name that is
+recognized.
+(In particular, this differs from
+.Xr strtofflags 3 ,
+which stops parsing at the first unrecognized name.)
+.Ss ACL Handling
+XXX This needs serious help.
+XXX
+.Pp
+An
+.Dq Access Control List
+(ACL) is a list of permissions that grant access to particular users or
+groups beyond what would normally be provided by standard POSIX mode bits.
+The ACL handling here addresses some deficiencies in the POSIX.1e draft 17 ACL
+specification.
+In particular, POSIX.1e draft 17 specifies several different formats, but
+none of those formats include both textual user/group names and numeric
+UIDs/GIDs.
+.Pp
+XXX explain ACL stuff XXX

+ * Utility to match up hardlinks.
+ *
+ * The 'struct archive_entry_linkresolver' is a cache of archive entries
+ * for files with multiple links.  Here's how to use it:
+ *   1. Create a lookup object with archive_entry_linkresolver_new()
+ *   2. Tell it the archive format you're using.
+ *   3. Hand each archive_entry to archive_entry_linkify().
+ *      That function will return 0, 1, or 2 entries that should
+ *      be written.
+ *   4. Call archive_entry_linkify(resolver, NULL) until
+ *      no more entries are returned.
+ *   5. Call archive_entry_link_resolver_free(resolver) to free resources.
+ *
+ * The entries returned have their hardlink and size fields updated
+ * appropriately.  If an entry is passed in that does not refer to
+ * a file with multiple links, it is returned unchanged.  The intention
+ * is that you should be able to simply filter all entries through
+ * this machine.
+ *
+ * To make things more efficient, be sure that each entry has a valid
+ * nlinks value.  The hardlink cache uses this to track when all links
+ * have been found.  If the nlinks value is zero, it will keep every
+ * name in the cache indefinitely, which can use a lot of memory.
+ *
+ * Note that archive_entry_size() is reset to zero if the file
+ * body should not be written to the archive.  Pay attention!
+ */
+struct archive_entry_linkresolver;
+
+/*
+ * There are three different strategies for marking hardlinks.
+ * The descriptions below name them after the best-known
+ * formats that rely on each strategy:
+ *
+ * "Old cpio" is the simplest, it always returns any entry unmodified.
+ *    As far as I know, only cpio formats use this.  Old cpio archives
+ *    store every link with the full body; the onus is on the dearchiver
+ *    to detect and properly link the files as they are restored.
+ * "tar" is also pretty simple; it caches a copy the first time it sees
+ *    any link.  Subsequent appearances are modified to be hardlink
+ *    references to the first one without any body.  Used by all tar
+ *    formats, although the newest tar formats permit the "old cpio" strategy
+ *    as well.  This strategy is very simple for the dearchiver,
+ *    and reasonably straightforward for the archiver.
+ * "new cpio" is trickier.  It stores the body only with the last
+ *    occurrence.  The complication is that we might not
+ *    see every link to a particular file in a single session, so
+ *    there's no easy way to know when we've seen the last occurrence.
+ *    The solution here is to queue one link until we see the next.
+ *    At the end of the session, you can enumerate any remaining
+ *    entries by calling archive_entry_linkify(NULL) and store those
+ *    bodies.  If you have a file with three links l1, l2, and l3,
+ *    you'll get the following behavior if you see all three links:
+ *           linkify(l1) => NULL   (the resolver stores l1 internally)
+ *           linkify(l2) => l1     (resolver stores l2, you write l1)
+ *           linkify(l3) => l2, l3 (all links seen, you can write both).
+ *    If you only see l1 and l2, you'll get this behavior:
+ *           linkify(l1) => NULL
+ *           linkify(l2) => l1
+ *           linkify(NULL) => l2   (at end, you retrieve remaining links)
+ *    As the name suggests, this strategy is used by newer cpio variants.
+ *    It's noticably more complex for the archiver, slightly more complex
+ *    for the dearchiver than the tar strategy, but makes it straightforward
+ *    to restore a file using any link by simply continuing to scan until
+ *    you see a link that is stored with a body.  In contrast, the tar
+ *    strategy requires you to rescan the archive from the beginning to
+ *    correctly extract an arbitrary link.

+.Sh DESCRIPTION
+These functions provide a complete API for reading streaming archives.
+The general process is to first create the
+.Tn struct archive
+object, set options, initialize the reader, iterate over the archive
+headers and associated data, then close the archive and release all
+resources.
+The following summary describes the functions in approximately the
+order they would be used:
+.Bl -tag -compact -width indent
+.It Fn archive_read_new
+Allocates and initializes a
+.Tn struct archive
+object suitable for reading from an archive.
+.It Xo
+.Fn archive_read_support_compression_bzip2 ,
+.Fn archive_read_support_compression_compress ,
+.Fn archive_read_support_compression_gzip ,
+.Fn archive_read_support_compression_lzma ,
+.Fn archive_read_support_compression_none ,
+.Fn archive_read_support_compression_xz
+.Xc
+Enables auto-detection code and decompression support for the
+specified compression.
+Returns
+.Cm ARCHIVE_OK
+if the compression is fully supported, or
+.Cm ARCHIVE_WARN
+if the compression is supported only through an external program.
+Note that decompression using an external program is usually slower than
+decompression through built-in libraries.
+Note that
+.Dq none
+is always enabled by default.
+.It Fn archive_read_support_compression_all
+Enables all available decompression filters.
+.It Fn archive_read_support_compression_program
+Data is fed through the specified external program before being dearchived.
+Note that this disables automatic detection of the compression format,
+so it makes no sense to specify this in conjunction with any other
+decompression option.
+.It Fn archive_read_support_compression_program_signature
+This feeds data through the specified external program
+but only if the initial bytes of the data match the specified
+signature value.
+.It Xo
+.Fn archive_read_support_format_all ,
+.Fn archive_read_support_format_ar ,
+.Fn archive_read_support_format_cpio ,
+.Fn archive_read_support_format_empty ,
+.Fn archive_read_support_format_iso9660 ,
+.Fn archive_read_support_format_mtree ,
+.Fn archive_read_support_format_tar ,
+.Fn archive_read_support_format_zip
+.Xc
+Enables support---including auto-detection code---for the
+specified archive format.
+For example,
+.Fn archive_read_support_format_tar
+enables support for a variety of standard tar formats, old-style tar,
+ustar, pax interchange format, and many common variants.
+For convenience,
+.Fn archive_read_support_format_all
+enables support for all available formats.
+Only empty archives are supported by default.
+.It Fn archive_read_support_format_raw
+The
+.Dq raw
+format handler allows libarchive to be used to read arbitrary data.
+It treats any data stream as an archive with a single entry.
+The pathname of this entry is
+.Dq data ;
+all other entry fields are unset.
+This is not enabled by
+.Fn archive_read_support_format_all
+in order to avoid erroneous handling of damaged archives.
+.It Xo
+.Fn archive_read_set_filter_options ,
+.Fn archive_read_set_format_options ,
+.Fn archive_read_set_options
+.Xc
+Specifies options that will be passed to currently-registered
+filters (including decompression filters) and/or format readers.
+The argument is a comma-separated list of individual options.
+Individual options have one of the following forms:
+.Bl -tag -compact -width indent
+.It Ar option=value
+The option/value pair will be provided to every module.
+Modules that do not accept an option with this name will ignore it.
+.It Ar option
+The option will be provided to every module with a value of
+.Dq 1 .
+.It Ar !option
+The option will be provided to every module with a NULL value.
+.It Ar module:option=value , Ar module:option , Ar module:!option
+As above, but the corresponding option and value will be provided
+only to modules whose name matches
+.Ar module .
+.El
+The return value will be
+.Cm ARCHIVE_OK
+if any module accepts the option, or
+.Cm ARCHIVE_WARN
+if no module accepted the option, or
+.Cm ARCHIVE_FATAL
+if there was a fatal error while attempting to process the option.
+.Pp
+The currently supported options are:
+.Bl -tag -compact -width indent
+.It Format iso9660
+.Bl -tag -compact -width indent
+.It Cm joliet
+Support Joliet extensions.
+Defaults to enabled, use
+.Cm !joliet
+to disable.
+.El
+.El
+.It Fn archive_read_open
+The same as
+.Fn archive_read_open2 ,
+except that the skip callback is assumed to be
+.Dv NULL .
+.It Fn archive_read_open2
+Freeze the settings, open the archive, and prepare for reading entries.
+This is the most generic version of this call, which accepts
+four callback functions.
+Most clients will want to use
+.Fn archive_read_open_filename ,
+.Fn archive_read_open_FILE ,
+.Fn archive_read_open_fd ,
+or
+.Fn archive_read_open_memory
+instead.
+The library invokes the client-provided functions to obtain
+raw bytes from the archive.
+.It Fn archive_read_open_FILE
+Like
+.Fn archive_read_open ,
+except that it accepts a
+.Ft "FILE *"
+pointer.
+This function should not be used with tape drives or other devices
+that require strict I/O blocking.
+.It Fn archive_read_open_fd
+Like
+.Fn archive_read_open ,
+except that it accepts a file descriptor and block size rather than
+a set of function pointers.
+Note that the file descriptor will not be automatically closed at
+end-of-archive.
+This function is safe for use with tape drives or other blocked devices.
+.It Fn archive_read_open_file
+This is a deprecated synonym for
+.Fn archive_read_open_filename .
+.It Fn archive_read_open_filename
+Like
+.Fn archive_read_open ,
+except that it accepts a simple filename and a block size.
+A NULL filename represents standard input.
+This function is safe for use with tape drives or other blocked devices.
+.It Fn archive_read_open_memory
+Like
+.Fn archive_read_open ,
+except that it accepts a pointer and size of a block of
+memory containing the archive data.
+.It Fn archive_read_next_header
+Read the header for the next entry and return a pointer to
+a
+.Tn struct archive_entry .
+This is a convenience wrapper around
+.Fn archive_read_next_header2
+that reuses an internal
+.Tn struct archive_entry
+object for each request.
+.It Fn archive_read_next_header2
+Read the header for the next entry and populate the provided
+.Tn struct archive_entry .
+.It Fn archive_read_data
+Read data associated with the header just read.
+Internally, this is a convenience function that calls
+.Fn archive_read_data_block
+and fills any gaps with nulls so that callers see a single
+continuous stream of data.
+.It Fn archive_read_data_block
+Return the next available block of data for this entry.
+Unlike
+.Fn archive_read_data ,
+the
+.Fn archive_read_data_block
+function avoids copying data and allows you to correctly handle
+sparse files, as supported by some archive formats.
+The library guarantees that offsets will increase and that blocks
+will not overlap.
+Note that the blocks returned from this function can be much larger
+than the block size read from disk, due to compression
+and internal buffer optimizations.
+.It Fn archive_read_data_skip
+A convenience function that repeatedly calls
+.Fn archive_read_data_block
+to skip all of the data for this archive entry.
+.\" #if ARCHIVE_API_VERSION < 3
+.It Fn archive_read_data_into_buffer
+This function is deprecated and will be removed.
+Use
+.Fn archive_read_data
+instead.
+.\" #endif
+.It Fn archive_read_data_into_fd
+A convenience function that repeatedly calls
+.Fn archive_read_data_block
+to copy the entire entry to the provided file descriptor.
+.It Fn archive_read_extract , Fn archive_read_extract_set_skip_file
+A convenience function that wraps the corresponding
+.Xr archive_write_disk 3
+interfaces.
+The first call to
+.Fn archive_read_extract
+creates a restore object using
+.Xr archive_write_disk_new 3
+and
+.Xr archive_write_disk_set_standard_lookup 3 ,
+then transparently invokes
+.Xr archive_write_disk_set_options 3 ,
+.Xr archive_write_header 3 ,
+.Xr archive_write_data 3 ,
+and
+.Xr archive_write_finish_entry 3
+to create the entry on disk and copy data into it.
+The
+.Va flags
+argument is passed unmodified to
+.Xr archive_write_disk_set_options 3 .
+.It Fn archive_read_extract2
+This is another version of
+.Fn archive_read_extract
+that allows you to provide your own restore object.
+In particular, this allows you to override the standard lookup functions
+using
+.Xr archive_write_disk_set_group_lookup 3 ,
+and
+.Xr archive_write_disk_set_user_lookup 3 .
+Note that
+.Fn archive_read_extract2
+does not accept a
+.Va flags
+argument; you should use
+.Fn archive_write_disk_set_options
+to set the restore options yourself.
+.It Fn archive_read_extract_set_progress_callback
+Sets a pointer to a user-defined callback that can be used
+for updating progress displays during extraction.
+The progress function will be invoked during the extraction of large
+regular files.
+The progress function will be invoked with the pointer provided to this call.
+Generally, the data pointed to should include a reference to the archive
+object and the archive_entry object so that various statistics
+can be retrieved for the progress display.
+.It Fn archive_read_close
+Complete the archive and invoke the close callback.
+.It Fn archive_read_finish
+Invokes
+.Fn archive_read_close
+if it was not invoked manually, then release all resources.
+Note: In libarchive 1.x, this function was declared to return
+.Ft void ,
+which made it impossible to detect certain errors when
+.Fn archive_read_close
+was invoked implicitly from this function.
+The declaration is corrected beginning with libarchive 2.0.
+.El
+.Pp
+Note that the library determines most of the relevant information about
+the archive by inspection.
+In particular, it automatically detects
+.Xr gzip 1
+or
+.Xr bzip2 1
+compression and transparently performs the appropriate decompression.
+It also automatically detects the archive format.
+.Pp
+A complete description of the
+.Tn struct archive
+and
+.Tn struct archive_entry
+objects can be found in the overview manual page for
+.Xr libarchive 3 .
+.Sh CLIENT CALLBACKS
+The callback functions must match the following prototypes:
+.Bl -item -offset indent
+.It
+.Ft typedef ssize_t
+.Fo archive_read_callback
+.Fa "struct archive *"
+.Fa "void *client_data"
+.Fa "const void **buffer"
+.Fc
+.It
+.\" #if ARCHIVE_API_VERSION < 2
+.Ft typedef int
+.Fo archive_skip_callback
+.Fa "struct archive *"
+.Fa "void *client_data"
+.Fa "size_t request"
+.Fc
+.\" #else
+.\" .Ft typedef off_t
+.\" .Fo archive_skip_callback
+.\" .Fa "struct archive *"
+.\" .Fa "void *client_data"
+.\" .Fa "off_t request"
+.\" .Fc
+.\" #endif
+.It
+.Ft typedef int
+.Fn archive_open_callback "struct archive *" "void *client_data"
+.It
+.Ft typedef int
+.Fn archive_close_callback "struct archive *" "void *client_data"
+.El
+.Pp
+The open callback is invoked by
+.Fn archive_open .
+It should return
+.Cm ARCHIVE_OK
+if the underlying file or data source is successfully
+opened.
+If the open fails, it should call
+.Fn archive_set_error
+to register an error code and message and return
+.Cm ARCHIVE_FATAL .
+.Pp
+The read callback is invoked whenever the library
+requires raw bytes from the archive.
+The read callback should read data into a buffer,
+set the
+.Li const void **buffer
+argument to point to the available data, and
+return a count of the number of bytes available.
+The library will invoke the read callback again
+only after it has consumed this data.
+The library imposes no constraints on the size
+of the data blocks returned.
+On end-of-file, the read callback should
+return zero.
+On error, the read callback should invoke
+.Fn archive_set_error
+to register an error code and message and
+return -1.
+.Pp
+The skip callback is invoked when the
+library wants to ignore a block of data.
+The return value is the number of bytes actually
+skipped, which may differ from the request.
+If the callback cannot skip data, it should return
+zero.
+If the skip callback is not provided (the
+function pointer is
+.Dv NULL ),
+the library will invoke the read function
+instead and simply discard the result.
+A skip callback can provide significant
+performance gains when reading uncompressed
+archives from slow disk drives or other media
+that can skip quickly.
+.Pp
+The close callback is invoked by archive_close when
+the archive processing is complete.
+The callback should return
+.Cm ARCHIVE_OK
+on success.
+On failure, the callback should invoke
+.Fn archive_set_error
+to register an error code and message and
+return
+.Cm ARCHIVE_FATAL.
+.Sh EXAMPLE
+The following illustrates basic usage of the library.
+In this example,
+the callback functions are simply wrappers around the standard
+.Xr open 2 ,
+.Xr read 2 ,
+and
+.Xr close 2
+system calls.
+.Bd -literal -offset indent
+void
+list_archive(const char *name)
+{
+  struct mydata *mydata;
+  struct archive *a;
+  struct archive_entry *entry;
+
+  mydata = malloc(sizeof(struct mydata));
+  a = archive_read_new();
+  mydata->name = name;
+  archive_read_support_compression_all(a);
+  archive_read_support_format_all(a);
+  archive_read_open(a, mydata, myopen, myread, myclose);
+  while (archive_read_next_header(a, &entry) == ARCHIVE_OK) {
+    printf("%s\\n",archive_entry_pathname(entry));
+    archive_read_data_skip(a);
+  }
+  archive_read_finish(a);
+  free(mydata);
+}
+
+ssize_t
+myread(struct archive *a, void *client_data, const void **buff)
+{
+  struct mydata *mydata = client_data;
+
+  *buff = mydata->buff;
+  return (read(mydata->fd, mydata->buff, 10240));
+}
+
+int
+myopen(struct archive *a, void *client_data)
+{
+  struct mydata *mydata = client_data;
+
+  mydata->fd = open(mydata->name, O_RDONLY);
+  return (mydata->fd >= 0 ? ARCHIVE_OK : ARCHIVE_FATAL);
+}
+
+int
+myclose(struct archive *a, void *client_data)
+{
+  struct mydata *mydata = client_data;
+
+  if (mydata->fd > 0)
+    close(mydata->fd);
+  return (ARCHIVE_OK);
+}
+.Ed
+.Sh RETURN VALUES
+Most functions return zero on success, non-zero on error.
+The possible return codes include:
+.Cm ARCHIVE_OK
+(the operation succeeded),
+.Cm ARCHIVE_WARN
+(the operation succeeded but a non-critical error was encountered),
+.Cm ARCHIVE_EOF
+(end-of-archive was encountered),
+.Cm ARCHIVE_RETRY
+(the operation failed but can be retried),
+and
+.Cm ARCHIVE_FATAL
+(there was a fatal error; the archive should be closed immediately).
+Detailed error codes and textual descriptions are available from the
+.Fn archive_errno
+and
+.Fn archive_error_string
+functions.
+.Pp
+.Fn archive_read_new
+returns a pointer to a freshly allocated
+.Tn struct archive
+object.
+It returns
+.Dv NULL
+on error.
+.Pp
+.Fn archive_read_data
+returns a count of bytes actually read or zero at the end of the entry.
+On error, a value of
+.Cm ARCHIVE_FATAL ,
+.Cm ARCHIVE_WARN ,
+or
+.Cm ARCHIVE_RETRY
+is returned and an error code and textual description can be retrieved from the
+.Fn archive_errno
+and
+.Fn archive_error_string
+functions.
+.Pp
+The library expects the client callbacks to behave similarly.
+If there is an error, you can use
+.Fn archive_set_error
+to set an appropriate error code and description,
+then return one of the non-zero values above.
+(Note that the value eventually returned to the client may
+not be the same; many errors that are not critical at the level
+of basic I/O can prevent the archive from being properly read,
+thus most I/O errors eventually cause
+.Cm ARCHIVE_FATAL
+to be returned.)

+The

+.Sh BUGS
+Many traditional archiver programs treat
+empty files as valid empty archives.
+For example, many implementations of
+.Xr tar 1
+allow you to append entries to an empty file.
+Of course, it is impossible to determine the format of an empty file
+by inspecting the contents, so this library treats empty files as
+having a special
+.Dq empty
+format.

+ * The next three functions comprise the peek/consume internal I/O

+ *
+ * In the ideal case, filters generate blocks of data
+ * and __archive_read_ahead() just returns pointers directly into
+ * those blocks.  Then __archive_read_consume() just bumps those
+ * pointers.  Only if your request would span blocks does the I/O
+ * layer use a copy buffer to provide you with a contiguous block of
+ * data.  The __archive_read_skip() is an optimization; it scans ahead
+ * very quickly (it usually translates into a seek() operation if
+ * you're reading uncompressed disk files).
+ *
+ * A couple of useful idioms:
+ *  * "I just want some data."  Ask for 1 byte and pay attention to
+ *    the "number of bytes available" from __archive_read_ahead().
+ *    You can consume more than you asked for; you just can't consume
+ *    more than is available.  If you consume everything that's
+ *    immediately available, the next read_ahead() call will pull
+ *    the next block.
+ *  * "I want to output a large block of data."  As above, ask for 1 byte,
+ *    emit all that's available (up to whatever limit you have), then
+ *    repeat until you're done.
+ *  * "I want to peek ahead by a large amount."  Ask for 4k or so, then
+ *    double and repeat until you get an error or have enough.  Note
+ *    that the I/O layer will likely end up expanding its copy buffer
+ *    to fit your request, so use this technique cautiously.  This
+ *    technique is used, for example, by some of the format tasting
+ *    code that has uncertain look-ahead needs.
+ *
+ * TODO: Someday, provide a more generic __archive_read_seek() for
+ * those cases where it's useful.  This is tricky because there are lots
+ * of cases where seek() is not available (reading gzip data from a
+ * network socket, for instance), so there needs to be a good way to
+ * communicate whether seek() is available and users of that interface
+ * need to use non-seeking strategies whenever seek() is not available.

+.Sh DESCRIPTION
+These functions provide an API for reading information about
+objects on disk.
+In particular, they provide an interface for populating
+.Tn struct archive_entry
+objects.
+.Bl -tag -width indent
+.It Fn archive_read_disk_new
+Allocates and initializes a
+.Tn struct archive
+object suitable for reading object information from disk.
+.It Xo
+.Fn archive_read_disk_set_symlink_logical ,
+.Fn archive_read_disk_set_symlink_physical ,
+.Fn archive_read_disk_set_symlink_hybrid
+.Xc
+This sets the mode used for handling symbolic links.
+The
+.Dq logical
+mode follows all symbolic links.
+The
+.Dq physical
+mode does not follow any symbolic links.
+The
+.Dq hybrid
+mode currently behaves identically to the
+.Dq logical
+mode.
+.It Xo
+.Fn archive_read_disk_gname ,
+.Fn archive_read_disk_uname
+.Xc
+Returns a user or group name given a gid or uid value.
+By default, these always return a NULL string.
+.It Xo
+.Fn archive_read_disk_set_gname_lookup ,
+.Fn archive_read_disk_set_uname_lookup
+.Xc
+These allow you to override the functions used for
+user and group name lookups.
+You may also provide a
+.Tn void *
+pointer to a private data structure and a cleanup function for
+that data.
+The cleanup function will be invoked when the
+.Tn struct archive
+object is destroyed or when new lookup functions are registered.
+.It Fn archive_read_disk_set_standard_lookup
+This convenience function installs a standard set of user
+and group name lookup functions.
+These functions use
+.Xr getpwid 3
+and
+.Xr getgrid 3
+to convert ids to names, defaulting to NULL if the names cannot
+be looked up.
+These functions also implement a simple memory cache to reduce
+the number of calls to
+.Xr getpwid 3
+and
+.Xr getgrid 3 .
+.It Fn archive_read_disk_entry_from_file
+Populates a
+.Tn struct archive_entry
+object with information about a particular file.
+The
+.Tn archive_entry
+object must have already been created with
+.Xr archive_entry_new 3
+and at least one of the source path or path fields must already be set.
+(If both are set, the source path will be used.)
+.Pp
+Information is read from disk using the path name from the
+.Tn struct archive_entry
+object.
+If a file descriptor is provided, some information will be obtained using
+that file descriptor, on platforms that support the appropriate
+system calls.
+.Pp
+If a pointer to a
+.Tn struct stat
+is provided, information from that structure will be used instead
+of reading from the disk where appropriate.
+This can provide performance benefits in scenarios where
+.Tn struct stat
+information has already been read from the disk as a side effect
+of some other operation.
+(For example, directory traversal libraries often provide this information.)
+.Pp
+Where necessary, user and group ids are converted to user and group names
+using the currently registered lookup functions above.
+This affects the file ownership fields and ACL values in the
+.Tn struct archive_entry
+object.
+.It Fn archive_read_close
+This currently does nothing.
+.It Fn archive_write_finish
+Invokes
+.Fn archive_write_close
+if it was not invoked manually, then releases all resources.
+.El
+More information about the
+.Va struct archive
+object and the overall design of the library can be found in the
+.Xr libarchive 3
+overview.
+.Sh EXAMPLE
+The following illustrates basic usage of the library by
+showing how to use it to copy an item on disk into an archive.
+.Bd -literal -offset indent
+void
+file_to_archive(struct archive *a, const char *name)
+{
+  char buff[8192];
+  size_t bytes_read;
+  struct archive *ard;
+  struct archive_entry *entry;
+  int fd;
+
+  ard = archive_read_disk_new();
+  archive_read_disk_set_standard_lookup(ard);
+  entry = archive_entry_new();
+  fd = open(name, O_RDONLY);
+  if (fd < 0)
+     return;
+  archive_entry_copy_sourcepath(entry, name);
+  archive_read_disk_entry_from_file(ard, entry, fd, NULL);
+  archive_write_header(a, entry);
+  while ((bytes_read = read(fd, buff, sizeof(buff))) > 0)
+    archive_write_data(a, buff, bytes_read);
+  archive_write_finish_entry(a);
+  archive_read_finish(ard);
+  archive_entry_free(entry);
+}
+.Ed
+.Sh RETURN VALUES
+Most functions return
+.Cm ARCHIVE_OK
+(zero) on success, or one of several negative
+error codes for errors.
+Specific error codes include:
+.Cm ARCHIVE_RETRY
+for operations that might succeed if retried,
+.Cm ARCHIVE_WARN
+for unusual conditions that do not prevent further operations, and
+.Cm ARCHIVE_FATAL
+for serious errors that make remaining operations impossible.
+The
+.Xr archive_errno 3
+and
+.Xr archive_error_string 3
+functions can be used to retrieve an appropriate error code and a
+textual error message.
+(See
+.Xr archive_util 3
+for details.)
+.Pp
+.Fn archive_read_disk_new
+returns a pointer to a newly-allocated
+.Tn struct archive
+object or NULL if the allocation failed for any reason.
+.Pp
+.Fn archive_read_disk_gname
+and
+.Fn archive_read_disk_uname
+return
+.Tn const char *
+pointers to the textual name or NULL if the lookup failed for any reason.
+The returned pointer points to internal storage that
+may be reused on the next call to either of these functions;
+callers should copy the string if they need to continue accessing it.

+.Sh HISTORY
+The
+.Nm libarchive
+library first appeared in
+.Fx 5.3 .
+The
+.Nm archive_read_disk
+interface was added to
+.Nm libarchive 2.6
+and first appeared in
+.Fx 8.0 .
+.Sh AUTHORS
+.An -nosplit
+The
+.Nm libarchive
+library was written by
+.An Tim Kientzle Aq kientzle@freebsd.org .
+.Sh BUGS
+The
+.Dq standard
+user name and group name lookup functions are not the defaults because
+.Xr getgrid 3
+and
+.Xr getpwid 3
+are sometimes too large for particular applications.
+The current design allows the application author to use a more
+compact implementation when appropriate.
+.Pp
+The full list of metadata read from disk by
+.Fn archive_read_disk_entry_from_file
+is necessarily system-dependent.
+.Pp
+The
+.Fn archive_read_disk_entry_from_file
+function reads as much information as it can from disk.
+Some method should be provided to limit this so that clients who
+do not need ACLs, for instance, can avoid the extra work needed
+to look up such information.
+.Pp
+This API should provide a set of methods for walking a directory tree.
+That would make it a direct parallel of the
+.Xr archive_read 3
+API.
+When such methods are implemented, the
+.Dq hybrid
+symbolic link mode will make sense.

+ *   * Volume descriptor table.  Each volume descriptor
+ *     is 2k and specifies basic format information.
+ *     The "Primary Volume Descriptor" (PVD) is defined by the
+ *     standard and should always be present; other volume
+ *     descriptors include various vendor-specific extensions.
+ *   * Files and directories.  Each file/dir is specified by
+ *     an "extent" (starting sector and length in bytes).
+ *     Dirs are just files with directory records packed one
+ *     after another.  The PVD contains a single dir entry
+ *     specifying the location of the root directory.  Everything
+ *     else follows from there.
+ *
+ * This module works by first reading the volume descriptors, then
+ * building a list of directory entries, sorted by starting
+ * sector.  At each step, I look for the earliest dir entry that
+ * hasn't yet been read, seek forward to that location and read
+ * that entry.  If it's a dir, I slurp in the new dir entries and
+ * add them to the heap; if it's a regular file, I return the
+ * corresponding archive_entry and wait for the client to request
+ * the file body.  This strategy allows us to read most compliant
+ * CDs with a single pass through the data, as required by libarchive.

+.Sh DESCRIPTION
+These functions provide access to various information about the
+.Tn struct archive
+object used in the
+.Xr libarchive 3
+library.
+.Bl -tag -compact -width indent
+.It Fn archive_clear_error
+Clears any error information left over from a previous call.
+Not generally used in client code.
+.It Fn archive_compression
+Returns a numeric code indicating the current compression.
+This value is set by
+.Fn archive_read_open .
+.It Fn archive_compression_name
+Returns a text description of the current compression suitable for display.
+.It Fn archive_copy_error
+Copies error information from one archive to another.
+.It Fn archive_errno
+Returns a numeric error code (see
+.Xr errno 2 )
+indicating the reason for the most recent error return.
+.It Fn archive_error_string
+Returns a textual error message suitable for display.
+The error message here is usually more specific than that
+obtained from passing the result of
+.Fn archive_errno
+to
+.Xr strerror 3 .
+.It Fn archive_file_count
+Returns a count of the number of files processed by this archive object.
+The count is incremented by calls to
+.Xr archive_write_header
+or
+.Xr archive_read_next_header .
+.It Fn archive_format
+Returns a numeric code indicating the format of the current
+archive entry.
+This value is set by a successful call to
+.Fn archive_read_next_header .
+Note that it is common for this value to change from
+entry to entry.
+For example, a tar archive might have several entries that
+utilize GNU tar extensions and several entries that do not.
+These entries will have different format codes.
+.It Fn archive_format_name
+A textual description of the format of the current entry.
+.It Fn archive_set_error
+Sets the numeric error code and error description that will be returned
+by
+.Fn archive_errno
+and
+.Fn archive_error_string .
+This function should be used within I/O callbacks to set system-specific
+error codes and error descriptions.
+This function accepts a printf-like format string and arguments.
+However, you should be careful to use only the following printf
+format specifiers:
+.Dq %c ,
+.Dq %d ,
+.Dq %jd ,
+.Dq %jo ,
+.Dq %ju ,
+.Dq %jx ,
+.Dq %ld ,
+.Dq %lo ,
+.Dq %lu ,
+.Dq %lx ,
+.Dq %o ,
+.Dq %u ,
+.Dq %s ,
+.Dq %x ,
+.Dq %% .
+Field-width specifiers and other printf features are
+not uniformly supported and should not be used.

+ *      (Regular expression is [a-z][-a-z]+)
+ *
+ *    - For a specfic format/filter, using the format name with ':'.
+ *        e.g  "zip:compression=9"
+ *        (This "compression=9" option entry is for "zip" format only)
+ *
+ *      If another entries follow it, those are not for
+ *      the specfic format/filter.

+ *          "zip" format/filter handler will get "compression=9"
+ *          all format/filter handler will get "opt=XXX"

+ * Much of the original file was unnecessary for libarchive, because

+ * The biggest remaining issue is the dev/ino emulation; libarchive

+ * considering alternative APIs.

+.Sh DESCRIPTION
+These functions provide a complete API for creating streaming
+archive files.
+The general process is to first create the
+.Tn struct archive
+object, set any desired options, initialize the archive, append entries, then
+close the archive and release all resources.
+The following summary describes the functions in approximately
+the order they are ordinarily used:
+.Bl -tag -width indent
+.It Fn archive_write_new
+Allocates and initializes a
+.Tn struct archive
+object suitable for writing a tar archive.
+.It Fn archive_write_set_bytes_per_block
+Sets the block size used for writing the archive data.
+Every call to the write callback function, except possibly the last one, will
+use this value for the length.
+The third parameter is a boolean that specifies whether or not the final block
+written will be padded to the full block size.
+If it is zero, the last block will not be padded.
+If it is non-zero, padding will be added both before and after compression.
+The default is to use a block size of 10240 bytes and to pad the last block.
+Note that a block size of zero will suppress internal blocking
+and cause writes to be sent directly to the write callback as they occur.
+.It Fn archive_write_get_bytes_per_block
+Retrieve the block size to be used for writing.
+A value of -1 here indicates that the library should use default values.
+A value of zero indicates that internal blocking is suppressed.
+.It Fn archive_write_set_bytes_in_last_block
+Sets the block size used for writing the last block.
+If this value is zero, the last block will be padded to the same size
+as the other blocks.
+Otherwise, the final block will be padded to a multiple of this size.
+In particular, setting it to 1 will cause the final block to not be padded.
+For compressed output, any padding generated by this option
+is applied only after the compression.
+The uncompressed data is always unpadded.
+The default is to pad the last block to the full block size (note that
+.Fn archive_write_open_filename
+will set this based on the file type).
+Unlike the other
+.Dq set
+functions, this function can be called after the archive is opened.

+The argument is a comma-separated list of individual options.
+Individual options have one of the following forms:
+.Bl -tag -compact -width indent
+.It Ar option=value
+The option/value pair will be provided to every module.
+Modules that do not accept an option with this name will ignore it.
+.It Ar option
+The option will be provided to every module with a value of
+.Dq 1 .
+.It Ar !option
+The option will be provided to every module with a NULL value.
+.It Ar module:option=value , Ar module:option , Ar module:!option
+As above, but the corresponding option and value will be provided
+only to modules whose name matches
+.Ar module .
+.El
+The return value will be
+.Cm ARCHIVE_OK
+if any module accepts the option, or
+.Cm ARCHIVE_WARN
+if no module accepted the option, or
+.Cm ARCHIVE_FATAL
+if there was a fatal error while attempting to process the option.
+.Pp
+The currently supported options are:
+.Bl -tag -compact -width indent
+.It Compressor gzip
+.Bl -tag -compact -width indent
+.It Cm compression-level
+The value is interpreted as a decimal integer specifying the

+.It Fn archive_write_open
+Freeze the settings, open the archive, and prepare for writing entries.
+This is the most generic form of this function, which accepts
+pointers to three callback functions which will be invoked by
+the compression layer to write the constructed archive.
+.It Fn archive_write_open_fd
+A convenience form of
+.Fn archive_write_open
+that accepts a file descriptor.
+The
+.Fn archive_write_open_fd
+function is safe for use with tape drives or other
+block-oriented devices.
+.It Fn archive_write_open_FILE
+A convenience form of
+.Fn archive_write_open
+that accepts a
+.Ft "FILE *"
+pointer.
+Note that
+.Fn archive_write_open_FILE
+is not safe for writing to tape drives or other devices
+that require correct blocking.
+.It Fn archive_write_open_file
+A deprecated synonym for
+.Fn archive_write_open_filename .
+.It Fn archive_write_open_filename
+A convenience form of
+.Fn archive_write_open
+that accepts a filename.
+A NULL argument indicates that the output should be written to standard output;
+an argument of
+.Dq -
+will open a file with that name.
+If you have not invoked
+.Fn archive_write_set_bytes_in_last_block ,
+then
+.Fn archive_write_open_filename
+will adjust the last-block padding depending on the file:
+it will enable padding when writing to standard output or
+to a character or block device node, it will disable padding otherwise.
+You can override this by manually invoking
+.Fn archive_write_set_bytes_in_last_block
+before calling
+.Fn archive_write_open .
+The
+.Fn archive_write_open_filename
+function is safe for use with tape drives or other
+block-oriented devices.
+.It Fn archive_write_open_memory
+A convenience form of
+.Fn archive_write_open
+that accepts a pointer to a block of memory that will receive
+the archive.
+The final
+.Ft "size_t *"
+argument points to a variable that will be updated
+after each write to reflect how much of the buffer
+is currently in use.
+You should be careful to ensure that this variable
+remains allocated until after the archive is
+closed.
+.It Fn archive_write_header
+Build and write a header using the data in the provided
+.Tn struct archive_entry
+structure.
+See
+.Xr archive_entry 3
+for information on creating and populating
+.Tn struct archive_entry
+objects.
+.It Fn archive_write_data
+Write data corresponding to the header just written.
+Returns number of bytes written or -1 on error.
+.It Fn archive_write_finish_entry
+Close out the entry just written.
+In particular, this writes out the final padding required by some formats.
+Ordinarily, clients never need to call this, as it
+is called automatically by
+.Fn archive_write_next_header
+and
+.Fn archive_write_close
+as needed.
+.It Fn archive_write_close
+Complete the archive and invoke the close callback.
+.It Fn archive_write_finish
+Invokes
+.Fn archive_write_close
+if it was not invoked manually, then releases all resources.
+Note that this function was declared to return
+.Ft void
+in libarchive 1.x, which made it impossible to detect errors when
+.Fn archive_write_close
+was invoked implicitly from this function.
+This is corrected beginning with libarchive 2.0.
+.El
+More information about the
+.Va struct archive
+object and the overall design of the library can be found in the
+.Xr libarchive 3
+overview.
+.Sh IMPLEMENTATION
+Compression support is built-in to libarchive, which uses zlib and bzlib
+to handle gzip and bzip2 compression, respectively.
+.Sh CLIENT CALLBACKS
+To use this library, you will need to define and register
+callback functions that will be invoked to write data to the
+resulting archive.
+These functions are registered by calling
+.Fn archive_write_open :
+.Bl -item -offset indent
+.It
+.Ft typedef int
+.Fn archive_open_callback "struct archive *" "void *client_data"
+.El
+.Pp
+The open callback is invoked by
+.Fn archive_write_open .
+It should return
+.Cm ARCHIVE_OK
+if the underlying file or data source is successfully
+opened.
+If the open fails, it should call
+.Fn archive_set_error
+to register an error code and message and return
+.Cm ARCHIVE_FATAL .
+.Bl -item -offset indent
+.It
+.Ft typedef ssize_t
+.Fo archive_write_callback
+.Fa "struct archive *"
+.Fa "void *client_data"
+.Fa "const void *buffer"
+.Fa "size_t length"
+.Fc
+.El
+.Pp
+The write callback is invoked whenever the library
+needs to write raw bytes to the archive.
+For correct blocking, each call to the write callback function
+should translate into a single
+.Xr write 2
+system call.
+This is especially critical when writing archives to tape drives.
+On success, the write callback should return the
+number of bytes actually written.
+On error, the callback should invoke
+.Fn archive_set_error
+to register an error code and message and return -1.
+.Bl -item -offset indent
+.It
+.Ft typedef int
+.Fn archive_close_callback "struct archive *" "void *client_data"
+.El
+.Pp
+The close callback is invoked by archive_close when
+the archive processing is complete.
+The callback should return
+.Cm ARCHIVE_OK
+on success.
+On failure, the callback should invoke
+.Fn archive_set_error
+to register an error code and message and
+return
+.Cm ARCHIVE_FATAL.
+.Sh EXAMPLE
+The following sketch illustrates basic usage of the library.
+In this example,
+the callback functions are simply wrappers around the standard
+.Xr open 2 ,
+.Xr write 2 ,
+and
+.Xr close 2
+system calls.

+.Sh RETURN VALUES
+Most functions return
+.Cm ARCHIVE_OK
+(zero) on success, or one of several non-zero
+error codes for errors.
+Specific error codes include:
+.Cm ARCHIVE_RETRY
+for operations that might succeed if retried,
+.Cm ARCHIVE_WARN
+for unusual conditions that do not prevent further operations, and
+.Cm ARCHIVE_FATAL
+for serious errors that make remaining operations impossible.
+The
+.Fn archive_errno
+and
+.Fn archive_error_string
+functions can be used to retrieve an appropriate error code and a
+textual error message.
+.Pp
+.Fn archive_write_new
+returns a pointer to a newly-allocated
+.Tn struct archive
+object.
+.Pp
+.Fn archive_write_data
+returns a count of the number of bytes actually written.
+On error, -1 is returned and the
+.Fn archive_errno
+and
+.Fn archive_error_string
+functions will return appropriate values.
+Note that if the client-provided write callback function
+returns a non-zero value, that error will be propagated back to the caller
+through whatever API function resulted in that call, which
+may include
+.Fn archive_write_header ,
+.Fn archive_write_data ,
+.Fn archive_write_close ,
+or
+.Fn archive_write_finish .
+The client callback can call
+.Fn archive_set_error
+to provide values that can then be retrieved by
+.Fn archive_errno
+and
+.Fn archive_error_string .

+.Sh HISTORY
+The
+.Nm libarchive
+library first appeared in
+.Fx 5.3 .
+.Sh AUTHORS
+.An -nosplit
+The
+.Nm libarchive
+library was written by
+.An Tim Kientzle Aq kientzle@acm.org .
+.Sh BUGS
+There are many peculiar bugs in historic tar implementations that may cause
+certain programs to reject archives written by this library.
+For example, several historic implementations calculated header checksums
+incorrectly and will thus reject valid archives; GNU tar does not fully support
+pax interchange format; some old tar implementations required specific
+field terminations.
+.Pp
+The default pax interchange format eliminates most of the historic
+tar limitations and provides a generic key/value attribute facility
+for vendor-defined extensions.
+One oversight in POSIX is the failure to provide a standard attribute
+for large device numbers.
+This library uses
+.Dq SCHILY.devminor
+and
+.Dq SCHILY.devmajor
+for device numbers that exceed the range supported by the backwards-compatible
+ustar header.
+These keys are compatible with Joerg Schilling's
+.Nm star
+archiver.
+Other implementations may not recognize these keys and will thus be unable
+to correctly restore device nodes with large device numbers from archives
+created by this library.

+.Sh DESCRIPTION
+These functions provide a complete API for creating objects on
+disk from
+.Tn struct archive_entry
+descriptions.
+They are most naturally used when extracting objects from an archive
+using the
+.Fn archive_read
+interface.
+The general process is to read
+.Tn struct archive_entry
+objects from an archive, then write those objects to a
+.Tn struct archive
+object created using the
+.Fn archive_write_disk
+family functions.
+This interface is deliberately very similar to the
+.Fn archive_write
+interface used to write objects to a streaming archive.
+.Bl -tag -width indent
+.It Fn archive_write_disk_new
+Allocates and initializes a
+.Tn struct archive
+object suitable for writing objects to disk.
+.It Fn archive_write_disk_set_skip_file
+Records the device and inode numbers of a file that should not be
+overwritten.
+This is typically used to ensure that an extraction process does not
+overwrite the archive from which objects are being read.
+This capability is technically unnecessary but can be a significant
+performance optimization in practice.
+.It Fn archive_write_disk_set_options
+The options field consists of a bitwise OR of one or more of the
+following values:
+.Bl -tag -compact -width "indent"
+.It Cm ARCHIVE_EXTRACT_OWNER
+The user and group IDs should be set on the restored file.
+By default, the user and group IDs are not restored.
+.It Cm ARCHIVE_EXTRACT_PERM
+Full permissions (including SGID, SUID, and sticky bits) should
+be restored exactly as specified, without obeying the
+current umask.
+Note that SUID and SGID bits can only be restored if the
+user and group ID of the object on disk are correct.
+If
+.Cm ARCHIVE_EXTRACT_OWNER
+is not specified, then SUID and SGID bits will only be restored
+if the default user and group IDs of newly-created objects on disk
+happen to match those specified in the archive entry.
+By default, only basic permissions are restored, and umask is obeyed.
+.It Cm ARCHIVE_EXTRACT_TIME
+The timestamps (mtime, ctime, and atime) should be restored.
+By default, they are ignored.
+Note that restoring of atime is not currently supported.
+.It Cm ARCHIVE_EXTRACT_NO_OVERWRITE
+Existing files on disk will not be overwritten.
+By default, existing regular files are truncated and overwritten;
+existing directories will have their permissions updated;
+other pre-existing objects are unlinked and recreated from scratch.
+.It Cm ARCHIVE_EXTRACT_UNLINK
+Existing files on disk will be unlinked before any attempt to
+create them.
+In some cases, this can prove to be a significant performance improvement.
+By default, existing files are truncated and rewritten, but
+the file is not recreated.
+In particular, the default behavior does not break existing hard links.
+.It Cm ARCHIVE_EXTRACT_ACL
+Attempt to restore ACLs.
+By default, extended ACLs are ignored.
+.It Cm ARCHIVE_EXTRACT_FFLAGS
+Attempt to restore extended file flags.
+By default, file flags are ignored.
+.It Cm ARCHIVE_EXTRACT_XATTR
+Attempt to restore POSIX.1e extended attributes.
+By default, they are ignored.
+.It Cm ARCHIVE_EXTRACT_SECURE_SYMLINKS
+Refuse to extract any object whose final location would be altered
+by a symlink on disk.
+This is intended to help guard against a variety of mischief
+caused by archives that (deliberately or otherwise) extract
+files outside of the current directory.
+The default is not to perform this check.
+If
+.Cm ARCHIVE_EXTRACT_UNLINK
+is specified together with this option, the library will
+remove any intermediate symlinks it finds and return an
+error only if such symlink could not be removed.
+.It Cm ARCHIVE_EXTRACT_SECURE_NODOTDOT
+Refuse to extract a path that contains a
+.Pa ..
+element anywhere within it.
+The default is to not refuse such paths.
+Note that paths ending in
+.Pa ..
+always cause an error, regardless of this flag.
+.It Cm ARCHIVE_EXTRACT_SPARSE
+Scan data for blocks of NUL bytes and try to recreate them with holes.
+This results in sparse files, independent of whether the archive format
+supports or uses them.
+.El
+.It Xo
+.Fn archive_write_disk_set_group_lookup ,
+.Fn archive_write_disk_set_user_lookup
+.Xc
+The
+.Tn struct archive_entry
+objects contain both names and ids that can be used to identify users
+and groups.
+These names and ids describe the ownership of the file itself and
+also appear in ACL lists.
+By default, the library uses the ids and ignores the names, but
+this can be overridden by registering user and group lookup functions.
+To register, you must provide a lookup function which
+accepts both a name and id and returns a suitable id.
+You may also provide a
+.Tn void *
+pointer to a private data structure and a cleanup function for
+that data.
+The cleanup function will be invoked when the
+.Tn struct archive
+object is destroyed.
+.It Fn archive_write_disk_set_standard_lookup
+This convenience function installs a standard set of user
+and group lookup functions.
+These functions use
+.Xr getpwnam 3
+and
+.Xr getgrnam 3
+to convert names to ids, defaulting to the ids if the names cannot
+be looked up.
+These functions also implement a simple memory cache to reduce
+the number of calls to
+.Xr getpwnam 3
+and
+.Xr getgrnam 3 .
+.It Fn archive_write_header
+Build and write a header using the data in the provided
+.Tn struct archive_entry
+structure.
+See
+.Xr archive_entry 3
+for information on creating and populating
+.Tn struct archive_entry
+objects.
+.It Fn archive_write_data
+Write data corresponding to the header just written.
+Returns number of bytes written or -1 on error.
+.It Fn archive_write_finish_entry
+Close out the entry just written.
+Ordinarily, clients never need to call this, as it
+is called automatically by
+.Fn archive_write_next_header
+and
+.Fn archive_write_close
+as needed.
+.It Fn archive_write_close
+Set any attributes that could not be set during the initial restore.
+For example, directory timestamps are not restored initially because
+restoring a subsequent file would alter that timestamp.
+Similarly, non-writable directories are initially created with
+write permissions (so that their contents can be restored).
+The
+.Nm
+library maintains a list of all such deferred attributes and
+sets them when this function is invoked.
+.It Fn archive_write_finish
+Invokes
+.Fn archive_write_close
+if it was not invoked manually, then releases all resources.
+.El
+More information about the
+.Va struct archive
+object and the overall design of the library can be found in the
+.Xr libarchive 3
+overview.
+Many of these functions are also documented under
+.Xr archive_write 3 .
+.Sh RETURN VALUES
+Most functions return
+.Cm ARCHIVE_OK
+(zero) on success, or one of several non-zero
+error codes for errors.
+Specific error codes include:
+.Cm ARCHIVE_RETRY
+for operations that might succeed if retried,
+.Cm ARCHIVE_WARN
+for unusual conditions that do not prevent further operations, and
+.Cm ARCHIVE_FATAL
+for serious errors that make remaining operations impossible.
+The
+.Fn archive_errno
+and
+.Fn archive_error_string
+functions can be used to retrieve an appropriate error code and a
+textual error message.
+.Pp
+.Fn archive_write_disk_new
+returns a pointer to a newly-allocated
+.Tn struct archive
+object.
+.Pp
+.Fn archive_write_data
+returns a count of the number of bytes actually written.
+On error, -1 is returned and the
+.Fn archive_errno
+and
+.Fn archive_error_string
+functions will return appropriate values.

+.Sh HISTORY
+The
+.Nm libarchive
+library first appeared in
+.Fx 5.3 .
+The
+.Nm archive_write_disk
+interface was added to
+.Nm libarchive 2.0
+and first appeared in
+.Fx 6.3 .
+.Sh AUTHORS
+.An -nosplit
+The
+.Nm libarchive
+library was written by
+.An Tim Kientzle Aq kientzle@acm.org .
+.Sh BUGS
+Directories are actually extracted in two distinct phases.
+Directories are created during
+.Fn archive_write_header ,
+but final permissions are not set until
+.Fn archive_write_close .
+This separation is necessary to correctly handle borderline
+cases such as a non-writable directory containing
+files, but can cause unexpected results.
+In particular, directory permissions are not fully
+restored until the archive is closed.
+If you use
+.Xr chdir 2
+to change the current directory between calls to
+.Fn archive_read_extract
+or before calling
+.Fn archive_read_close ,
+you may confuse the permission-setting logic with
+the result that directory permissions are restored
+incorrectly.
+.Pp
+The library attempts to create objects with filenames longer than
+.Cm PATH_MAX
+by creating prefixes of the full path and changing the current directory.
+Currently, this logic is limited in scope; the fixup pass does
+not work correctly for such objects and the symlink security check
+option disables the support for very long pathnames.
+.Pp
+Restoring the path
+.Pa aa/../bb
+does create each intermediate directory.
+In particular, the directory
+.Pa aa
+is created as well as the final object
+.Pa bb .
+In theory, this can be exploited to create an entire directory heirarchy
+with a single request.
+Of course, this does not work if the
+.Cm ARCHIVE_EXTRACT_NODOTDOT
+option is specified.
+.Pp
+Implicit directories are always created obeying the current umask.
+Explicit objects are created obeying the current umask unless
+.Cm ARCHIVE_EXTRACT_PERM
+is specified, in which case they current umask is ignored.
+.Pp
+SGID and SUID bits are restored only if the correct user and
+group could be set.
+If
+.Cm ARCHIVE_EXTRACT_OWNER
+is not specified, then no attempt is made to set the ownership.
+In this case, SGID and SUID bits are restored only if the
+user and group of the final object happen to match those specified
+in the entry.
+.Pp
+The
+.Dq standard
+user-id and group-id lookup functions are not the defaults because
+.Xr getgrnam 3
+and
+.Xr getpwnam 3
+are sometimes too large for particular applications.
+The current design allows the application author to use a more
+compact implementation when appropriate.
+.Pp
+There should be a corresponding
+.Nm archive_read_disk
+interface that walks a directory heirarchy and returns archive
+entry objects.

+.Sh NAME
+.Nm cpio
+.Nd format of cpio archive files
+.Sh DESCRIPTION
+The
+.Nm
+archive format collects any number of files, directories, and other
+file system objects (symbolic links, device nodes, etc.) into a single
+stream of bytes.
+.Ss General Format
+Each file system object in a
+.Nm
+archive comprises a header record with basic numeric metadata
+followed by the full pathname of the entry and the file data.
+The header record stores a series of integer values that generally
+follow the fields in
+.Va struct stat .
+(See
+.Xr stat 2
+for details.)
+The variants differ primarily in how they store those integers
+(binary, octal, or hexadecimal).
+The header is followed by the pathname of the
+entry (the length of the pathname is stored in the header)
+and any file data.
+The end of the archive is indicated by a special record with
+the pathname
+.Dq TRAILER!!! .
+.Ss PWB format
+XXX Any documentation of the original PWB/UNIX 1.0 format? XXX
+.Ss Old Binary Format
+The old binary
+.Nm
+format stores numbers as 2-byte and 4-byte binary values.
+Each entry begins with a header in the following format:
+.Bd -literal -offset indent
+struct header_old_cpio {
+        unsigned short   c_magic;
+        unsigned short   c_dev;
+        unsigned short   c_ino;
+        unsigned short   c_mode;
+        unsigned short   c_uid;
+        unsigned short   c_gid;
+        unsigned short   c_nlink;
+        unsigned short   c_rdev;
+       unsigned short   c_mtime[2];
+        unsigned short   c_namesize;
+       unsigned short   c_filesize[2];
+};
+.Ed
+.Pp
+The
+.Va unsigned short
+fields here are 16-bit integer values; the
+.Va unsigned int
+fields are 32-bit integer values.
+The fields are as follows
+.Bl -tag -width indent
+.It Va magic
+The integer value octal 070707.
+This value can be used to determine whether this archive is
+written with little-endian or big-endian integers.
+.It Va dev , Va ino
+The device and inode numbers from the disk.
+These are used by programs that read
+.Nm
+archives to determine when two entries refer to the same file.
+Programs that synthesize
+.Nm
+archives should be careful to set these to distinct values for each entry.
+.It Va mode
+The mode specifies both the regular permissions and the file type.
+It consists of several bit fields as follows:
+.Bl -tag -width "MMMMMMM" -compact
+.It 0170000
+This masks the file type bits.
+.It 0140000
+File type value for sockets.
+.It 0120000
+File type value for symbolic links.
+For symbolic links, the link body is stored as file data.
+.It 0100000
+File type value for regular files.
+.It 0060000
+File type value for block special devices.
+.It 0040000
+File type value for directories.
+.It 0020000
+File type value for character special devices.
+.It 0010000
+File type value for named pipes or FIFOs.
+.It 0004000
+SUID bit.
+.It 0002000
+SGID bit.
+.It 0001000
+Sticky bit.
+On some systems, this modifies the behavior of executables and/or directories.
+.It 0000777
+The lower 9 bits specify read/write/execute permissions
+for world, group, and user following standard POSIX conventions.
+.El
+.It Va uid , Va gid
+The numeric user id and group id of the owner.
+.It Va nlink
+The number of links to this file.
+Directories always have a value of at least two here.
+Note that hardlinked files include file data with every copy in the archive.
+.It Va rdev
+For block special and character special entries,
+this field contains the associated device number.
+For all other entry types, it should be set to zero by writers
+and ignored by readers.
+.It Va mtime
+Modification time of the file, indicated as the number
+of seconds since the start of the epoch,
+00:00:00 UTC January 1, 1970.
+The four-byte integer is stored with the most-significant 16 bits first
+followed by the least-significant 16 bits.
+Each of the two 16 bit values are stored in machine-native byte order.
+.It Va namesize
+The number of bytes in the pathname that follows the header.
+This count includes the trailing NUL byte.
+.It Va filesize
+The size of the file.
+Note that this archive format is limited to
+four gigabyte file sizes.
+See
+.Va mtime
+above for a description of the storage of four-byte integers.
+.El
+.Pp
+The pathname immediately follows the fixed header.
+If the
+.Cm namesize
+is odd, an additional NUL byte is added after the pathname.
+The file data is then appended, padded with NUL
+bytes to an even length.
+.Pp
+Hardlinked files are not given special treatment;
+the full file contents are included with each copy of the
+file.
+.Ss Portable ASCII Format
+.St -susv2
+standardized an ASCII variant that is portable across all
+platforms.
+It is commonly known as the
+.Dq old character
+format or as the
+.Dq odc
+format.
+It stores the same numeric fields as the old binary format, but
+represents them as 6-character or 11-character octal values.
+.Bd -literal -offset indent
+struct cpio_odc_header {
+        char    c_magic[6];
+        char    c_dev[6];
+        char    c_ino[6];
+        char    c_mode[6];
+        char    c_uid[6];
+        char    c_gid[6];
+        char    c_nlink[6];
+        char    c_rdev[6];
+        char    c_mtime[11];
+        char    c_namesize[6];
+        char    c_filesize[11];
+};
+.Ed
+.Pp
+The fields are identical to those in the old binary format.
+The name and file body follow the fixed header.
+Unlike the old binary format, there is no additional padding
+after the pathname or file contents.
+If the files being archived are themselves entirely ASCII, then
+the resulting archive will be entirely ASCII, except for the
+NUL byte that terminates the name field.
+.Ss New ASCII Format
+The "new" ASCII format uses 8-byte hexadecimal fields for
+all numbers and separates device numbers into separate fields
+for major and minor numbers.
+.Bd -literal -offset indent
+struct cpio_newc_header {
+        char    c_magic[6];
+        char    c_ino[8];
+        char    c_mode[8];
+        char    c_uid[8];
+        char    c_gid[8];
+        char    c_nlink[8];
+        char    c_mtime[8];
+        char    c_filesize[8];
+        char    c_devmajor[8];
+        char    c_devminor[8];
+        char    c_rdevmajor[8];
+        char    c_rdevminor[8];
+        char    c_namesize[8];
+        char    c_check[8];
+};
+.Ed
+.Pp
+Except as specified below, the fields here match those specified
+for the old binary format above.
+.Bl -tag -width indent
+.It Va magic
+The string
+.Dq 070701 .
+.It Va check
+This field is always set to zero by writers and ignored by readers.
+See the next section for more details.
+.El
+.Pp
+The pathname is followed by NUL bytes so that the total size
+of the fixed header plus pathname is a multiple of four.
+Likewise, the file data is padded to a multiple of four bytes.
+Note that this format supports only 4 gigabyte files (unlike the
+older ASCII format, which supports 8 gigabyte files).
+.Pp
+In this format, hardlinked files are handled by setting the
+filesize to zero for each entry except the last one that
+appears in the archive.
+.Ss New CRC Format
+The CRC format is identical to the new ASCII format described
+in the previous section except that the magic field is set
+to
+.Dq 070702
+and the
+.Va check
+field is set to the sum of all bytes in the file data.
+This sum is computed treating all bytes as unsigned values
+and using unsigned arithmetic.
+Only the least-significant 32 bits of the sum are stored.
+.Ss HP variants
+The
+.Nm cpio
+implementation distributed with HPUX used XXXX but stored
+device numbers differently XXX.
+.Ss Other Extensions and Variants
+Sun Solaris uses additional file types to store extended file
+data, including ACLs and extended attributes, as special
+entries in cpio archives.
+.Pp
+XXX Others? XXX
+.Sh BUGS
+The
+.Dq CRC
+format is mis-named, as it uses a simple checksum and
+not a cyclic redundancy check.
+.Pp
+The old binary format is limited to 16 bits for user id,
+group id, device, and inode numbers.
+It is limited to 4 gigabyte file sizes.
+.Pp
+The old ASCII format is limited to 18 bits for
+the user id, group id, device, and inode numbers.
+It is limited to 8 gigabyte file sizes.
+.Pp
+The new ASCII format is limited to 4 gigabyte file sizes.
+.Pp
+None of the cpio formats store user or group names,
+which are essential when moving files between systems with
+dissimilar user or group numbering.
+.Pp
+Especially when writing older cpio variants, it may be necessary
+to map actual device/inode values to synthesized values that
+fit the available fields.
+With very large filesystems, this may be necessary even for
+the newer formats.

+It has been supplanted in subsequent standards by
+.Xr pax 1 .
+The portable ASCII format is currently part of the specification for the
+.Xr pax 1
+utility.
+.Sh HISTORY
+The original cpio utility was written by Dick Haight
+while working in AT&T's Unix Support Group.
+It appeared in 1977 as part of PWB/UNIX 1.0, the
+.Dq Programmer's Work Bench
+derived from
+.At v6
+that was used internally at AT&T.
+Both the old binary and old character formats were in use
+by 1980, according to the System III source released
+by SCO under their
+.Dq Ancient Unix
+license.
+The character format was adopted as part of
+.St -p1003.1-88 .
+XXX when did "newc" appear?  Who invented it?  When did HP come out with their variant?  When did Sun introduce ACLs and extended attributes? XXX

+.Os
+.Sh NAME
+.Nm libarchive-formats
+.Nd archive formats supported by the libarchive library
+.Sh DESCRIPTION
+The
+.Xr libarchive 3
+library reads and writes a variety of streaming archive formats.
+Generally speaking, all of these archive formats consist of a series of
+.Dq entries .
+Each entry stores a single file system object, such as a file, directory,
+or symbolic link.
+.Pp
+The following provides a brief description of each format supported
+by libarchive, with some information about recognized extensions or
+limitations of the current library support.
+Note that just because a format is supported by libarchive does not
+imply that a program that uses libarchive will support that format.
+Applications that use libarchive specify which formats they wish
+to support, though many programs do use libarchive convenience
+functions to enable all supported formats.
+.Ss Tar Formats
+The
+.Xr libarchive 3
+library can read most tar archives.
+However, it only writes POSIX-standard
+.Dq ustar
+and
+.Dq pax interchange
+formats.
+.Pp
+All tar formats store each entry in one or more 512-byte records.
+The first record is used for file metadata, including filename,
+timestamp, and mode information, and the file data is stored in
+subsequent records.
+Later variants have extended this by either appropriating undefined
+areas of the header record, extending the header to multiple records,
+or by storing special entries that modify the interpretation of
+subsequent entries.
+.Pp
+.Bl -tag -width indent
+.It Cm gnutar
+The
+.Xr libarchive 3
+library can read GNU-format tar archives.
+It currently supports the most popular GNU extensions, including
+modern long filename and linkname support, as well as atime and ctime data.
+The libarchive library does not support multi-volume
+archives, nor the old GNU long filename format.
+It can read GNU sparse file entries, including the new POSIX-based
+formats, but cannot write GNU sparse file entries.
+.It Cm pax
+The
+.Xr libarchive 3
+library can read and write POSIX-compliant pax interchange format
+archives.
+Pax interchange format archives are an extension of the older ustar
+format that adds a separate entry with additional attributes stored
+as key/value pairs immediately before each regular entry.
+The presence of these additional entries is the only difference between
+pax interchange format and the older ustar format.
+The extended attributes are of unlimited length and are stored
+as UTF-8 Unicode strings.
+Keywords defined in the standard are in all lowercase; vendors are allowed
+to define custom keys by preceding them with the vendor name in all uppercase.
+When writing pax archives, libarchive uses many of the SCHILY keys
+defined by Joerg Schilling's
+.Dq star
+archiver and a few LIBARCHIVE keys.
+The libarchive library can read most of the SCHILY keys
+and most of the GNU keys introduced by GNU tar.
+It silently ignores any keywords that it does not understand.
+.It Cm restricted pax
+The libarchive library can also write pax archives in which it
+attempts to suppress the extended attributes entry whenever
+possible.
+The result will be identical to a ustar archive unless the
+extended attributes entry is required to store a long file
+name, long linkname, extended ACL, file flags, or if any of the standard
+ustar data (user name, group name, UID, GID, etc) cannot be fully
+represented in the ustar header.
+In all cases, the result can be dearchived by any program that
+can read POSIX-compliant pax interchange format archives.
+Programs that correctly read ustar format (see below) will also be
+able to read this format; any extended attributes will be extracted as
+separate files stored in
+.Pa PaxHeader
+directories.
+.It Cm ustar
+The libarchive library can both read and write this format.
+This format has the following limitations:
+.Bl -bullet -compact
+.It
+Device major and minor numbers are limited to 21 bits.
+Nodes with larger numbers will not be added to the archive.
+.It
+Path names in the archive are limited to 255 bytes.
+(Shorter if there is no / character in exactly the right place.)
+.It
+Symbolic links and hard links are stored in the archive with
+the name of the referenced file.
+This name is limited to 100 bytes.
+.It
+Extended attributes, file flags, and other extended
+security information cannot be stored.
+.It
+Archive entries are limited to 8 gigabytes in size.
+.El
+Note that the pax interchange format has none of these restrictions.
+.El
+.Pp
+The libarchive library also reads a variety of commonly-used extensions to
+the basic tar format.
+These extensions are recognized automatically whenever they appear.
+.Bl -tag -width indent
+.It Numeric extensions.
+The POSIX standards require fixed-length numeric fields to be written with
+some character position reserved for terminators.
+Libarchive allows these fields to be written without terminator characters.
+This extends the allowable range; in particular, ustar archives with this
+extension can support entries up to 64 gigabytes in size.
+Libarchive also recognizes base-256 values in most numeric fields.
+This essentially removes all limitations on file size, modification time,
+and device numbers.
+.It Solaris extensions
+Libarchive recognizes ACL and extended attribute records written
+by Solaris tar.
+Currently, libarchive only has support for old-style ACLs; the
+newer NFSv4 ACLs are recognized but discarded.
+.El
+.Pp
+The first tar program appeared in Seventh Edition Unix in 1979.
+The first official standard for the tar file format was the
+.Dq ustar
+(Unix Standard Tar) format defined by POSIX in 1988.
+POSIX.1-2001 extended the ustar format to create the
+.Dq pax interchange
+format.
+.Ss Cpio Formats
+The libarchive library can read a number of common cpio variants and can write
+.Dq odc
+and
+.Dq newc
+format archives.
+A cpio archive stores each entry as a fixed-size header followed
+by a variable-length filename and variable-length data.
+Unlike the tar format, the cpio format does only minimal padding
+of the header or file data.
+There are several cpio variants, which differ primarily in
+how they store the initial header: some store the values as
+octal or hexadecimal numbers in ASCII, others as binary values of
+varying byte order and length.
+.Bl -tag -width indent
+.It Cm binary
+The libarchive library transparently reads both big-endian and little-endian
+variants of the original binary cpio format.
+This format used 32-bit binary values for file size and mtime,
+and 16-bit binary values for the other fields.
+.It Cm odc
+The libarchive library can both read and write this
+POSIX-standard format, which is officially known as the
+.Dq cpio interchange format
+or the
+.Dq octet-oriented cpio archive format
+and sometimes unofficially referred to as the
+.Dq old character format .
+This format stores the header contents as octal values in ASCII.
+It is standard, portable, and immune from byte-order confusion.
+File sizes and mtime are limited to 33 bits (8GB file size),
+other fields are limited to 18 bits.
+.It Cm SVR4
+The libarchive library can read both CRC and non-CRC variants of
+this format.
+The SVR4 format uses eight-digit hexadecimal values for
+all header fields.
+This limits file size to 4GB, and also limits the mtime and
+other fields to 32 bits.
+The SVR4 format can optionally include a CRC of the file
+contents, although libarchive does not currently verify this CRC.
+.El
+.Pp
+Cpio first appeared in PWB/UNIX 1.0, which was released within
+AT&T in 1977.
+PWB/UNIX 1.0 formed the basis of System III Unix, released outside
+of AT&T in 1981.
+This makes cpio older than tar, although cpio was not included
+in Version 7 AT&T Unix.
+As a result, the tar command became much better known in universities
+and research groups that used Version 7.
+The combination of the
+.Nm find
+and
+.Nm cpio
+utilities provided very precise control over file selection.
+Unfortunately, the format has many limitations that make it unsuitable
+for widespread use.
+Only the POSIX format permits files over 4GB, and its 18-bit
+limit for most other fields makes it unsuitable for modern systems.
+In addition, cpio formats only store numeric UID/GID values (not
+usernames and group names), which can make it very difficult to correctly
+transfer archives across systems with dissimilar user numbering.
+.Ss Shar Formats
+A
+.Dq shell archive
+is a shell script that, when executed on a POSIX-compliant
+system, will recreate a collection of file system objects.
+The libarchive library can write two different kinds of shar archives:
+.Bl -tag -width indent
+.It Cm shar
+The traditional shar format uses a limited set of POSIX
+commands, including
+.Xr echo 1 ,
+.Xr mkdir 1 ,
+and
+.Xr sed 1 .
+It is suitable for portably archiving small collections of plain text files.
+However, it is not generally well-suited for large archives
+(many implementations of
+.Xr sh 1
+have limits on the size of a script) nor should it be used with non-text files.
+.It Cm shardump
+This format is similar to shar but encodes files using
+.Xr uuencode 1
+so that the result will be a plain text file regardless of the file contents.
+It also includes additional shell commands that attempt to reproduce as
+many file attributes as possible, including owner, mode, and flags.
+The additional commands used to restore file attributes make
+shardump archives less portable than plain shar archives.
+.El
+.Ss ISO9660 format
+Libarchive can read and extract from files containing ISO9660-compliant
+CDROM images.
+In many cases, this can remove the need to burn a physical CDROM
+just in order to read the files contained in an ISO9660 image.
+It also avoids security and complexity issues that come with
+virtual mounts and loopback devices.
+Libarchive supports the most common Rockridge extensions and has partial
+support for Joliet extensions.
+If both extensions are present, the Joliet extensions will be
+used and the Rockridge extensions will be ignored.
+In particular, this can create problems with hardlinks and symlinks,
+which are supported by Rockridge but not by Joliet.
+.Ss Zip format
+Libarchive can read and write zip format archives that have
+uncompressed entries and entries compressed with the
+.Dq deflate
+algorithm.
+Older zip compression algorithms are not supported.
+It can extract jar archives, archives that use Zip64 extensions and many
+self-extracting zip archives.
+Libarchive reads Zip archives as they are being streamed,
+which allows it to read archives of arbitrary size.
+It currently does not use the central directory; this
+limits libarchive's ability to support some self-extracting
+archives and ones that have been modified in certain ways.
+.Ss Archive (library) file format
+The Unix archive format (commonly created by the
+.Xr ar 1
+archiver) is a general-purpose format which is
+used almost exclusively for object files to be
+read by the link editor
+.Xr ld 1 .
+The ar format has never been standardised.
+There are two common variants:
+the GNU format derived from SVR4,
+and the BSD format, which first appeared in 4.4BSD.
+The two differ primarily in their handling of filenames
+longer than 15 characters:
+the GNU/SVR4 variant writes a filename table at the beginning of the archive;
+the BSD format stores each long filename in an extension
+area adjacent to the entry.
+Libarchive can read both extensions,
+including archives that may include both types of long filenames.
+Programs using libarchive can write GNU/SVR4 format
+if they provide a filename table to be written into
+the archive before any of the entries.
+Any entries whose names are not in the filename table
+will be written using BSD-style long filenames.
+This can cause problems for programs such as
+GNU ld that do not support the BSD-style long filenames.
+.Ss mtree
+Libarchive can read and write files in
+.Xr mtree 5
+format.
+This format is not a true archive format, but rather a textual description
+of a file hierarchy in which each line specifies the name of a file and
+provides specific metadata about that file.
+Libarchive can read all of the keywords supported by both
+the NetBSD and FreeBSD versions of
+.Xr mtree 1 ,
+although many of the keywords cannot currently be stored in an
+.Tn archive_entry
+object.
+When writing, libarchive supports use of the
+.Xr archive_write_set_options 3
+interface to specify which keywords should be included in the
+output.
+If libarchive was compiled with access to suitable
+cryptographic libraries (such as the OpenSSL libraries),
+it can compute hash entries such as
+.Cm sha512
+or
+.Cm md5
+from file data being written to the mtree writer.
+.Pp
+When reading an mtree file, libarchive will locate the corresponding
+files on disk using the
+.Cm contents
+keyword if present or the regular filename.
+If it can locate and open the file on disk, it will use that
+to fill in any metadata that is missing from the mtree file
+and will read the file contents and return those to the program
+using libarchive.
+If it cannot locate and open the file on disk, libarchive
+will return an error for any attempt to read the entry
+body.

+.Dt LIBARCHIVE 3
+.Os
+.Sh NAME
+.Nm libarchive
+.Nd functions for reading and writing streaming archives
+.Sh LIBRARY
+.Lb libarchive
+.Sh OVERVIEW
+The
+.Nm
+library provides a flexible interface for reading and writing
+streaming archive files such as tar and cpio.
+The library is inherently stream-oriented; readers serially iterate through
+the archive, writers serially add things to the archive.
+In particular, note that there is no built-in support for
+random access nor for in-place modification.
+.Pp
+When reading an archive, the library automatically detects the
+format and the compression.
+The library currently has read support for:
+.Bl -bullet -compact
+.It
+old-style tar archives,
+.It
+most variants of the POSIX
+.Dq ustar
+format,
+.It
+the POSIX
+.Dq pax interchange
+format,
+.It
+GNU-format tar archives,
+.It
+most common cpio archive formats,
+.It
+ISO9660 CD images (with or without RockRidge extensions),
+.It
+Zip archives.
+.El
+The library automatically detects archives compressed with
+.Xr gzip 1 ,
+.Xr bzip2 1 ,
+or
+.Xr compress 1
+and decompresses them transparently.
+.Pp
+When writing an archive, you can specify the compression
+to be used and the format to use.
+The library can write
+.Bl -bullet -compact
+.It
+POSIX-standard
+.Dq ustar
+archives,
+.It
+POSIX
+.Dq pax interchange format
+archives,
+.It
+POSIX octet-oriented cpio archives,
+.It
+two different variants of shar archives.
+.El
+Pax interchange format is an extension of the tar archive format that
+eliminates essentially all of the limitations of historic tar formats
+in a standard fashion that is supported
+by POSIX-compliant
+.Xr pax 1
+implementations on many systems as well as several newer implementations of
+.Xr tar 1 .
+Note that the default write format will suppress the pax extended
+attributes for most entries; explicitly requesting pax format will
+enable those attributes for all entries.
+.Pp
+The read and write APIs are accessed through the
+.Fn archive_read_XXX
+functions and the
+.Fn archive_write_XXX
+functions, respectively, and either can be used independently
+of the other.
+.Pp
+The rest of this manual page provides an overview of the library
+operation.
+More detailed information can be found in the individual manual
+pages for each API or utility function.
+.Sh READING AN ARCHIVE
+To read an archive, you must first obtain an initialized
+.Tn struct archive
+object from
+.Fn archive_read_new .
+You can then modify this object for the desired operations with the
+various
+.Fn archive_read_set_XXX
+and
+.Fn archive_read_support_XXX
+functions.
+In particular, you will need to invoke appropriate
+.Fn archive_read_support_XXX
+functions to enable the corresponding compression and format
+support.
+Note that these latter functions perform two distinct operations:
+they cause the corresponding support code to be linked into your
+program, and they enable the corresponding auto-detect code.
+Unless you have specific constraints, you will generally want
+to invoke
+.Fn archive_read_support_compression_all
+and
+.Fn archive_read_support_format_all
+to enable auto-detect for all formats and compression types
+currently supported by the library.
+.Pp
+Once you have prepared the
+.Tn struct archive
+object, you call
+.Fn archive_read_open
+to actually open the archive and prepare it for reading.
+There are several variants of this function;
+the most basic expects you to provide pointers to several
+functions that can provide blocks of bytes from the archive.
+There are convenience forms that allow you to
+specify a filename, file descriptor,
+.Ft "FILE *"
+object, or a block of memory from which to read the archive data.
+Note that the core library makes no assumptions about the
+size of the blocks read;
+callback functions are free to read whatever block size is
+most appropriate for the medium.
+.Pp
+Each archive entry consists of a header followed by a certain
+amount of data.
+You can obtain the next header with
+.Fn archive_read_next_header ,
+which returns a pointer to an
+.Tn struct archive_entry
+structure with information about the current archive element.
+If the entry is a regular file, then the header will be followed
+by the file data.
+You can use
+.Fn archive_read_data
+(which works much like the
+.Xr read 2
+system call)
+to read this data from the archive.
+You may prefer to use the higher-level
+.Fn archive_read_data_skip ,
+which reads and discards the data for this entry,
+.Fn archive_read_data_to_buffer ,
+which reads the data into an in-memory buffer,
+.Fn archive_read_data_to_file ,
+which copies the data to the provided file descriptor, or
+.Fn archive_read_extract ,
+which recreates the specified entry on disk and copies data
+from the archive.
+In particular, note that
+.Fn archive_read_extract
+uses the
+.Tn struct archive_entry
+structure that you provide it, which may differ from the
+entry just read from the archive.
+In particular, many applications will want to override the
+pathname, file permissions, or ownership.
+.Pp
+Once you have finished reading data from the archive, you
+should call
+.Fn archive_read_close
+to close the archive, then call
+.Fn archive_read_finish
+to release all resources, including all memory allocated by the library.
+.Pp
+The
+.Xr archive_read 3
+manual page provides more detailed calling information for this API.
+.Sh WRITING AN ARCHIVE
+You use a similar process to write an archive.
+The
+.Fn archive_write_new
+function creates an archive object useful for writing,
+the various
+.Fn archive_write_set_XXX
+functions are used to set parameters for writing the archive, and
+.Fn archive_write_open
+completes the setup and opens the archive for writing.
+.Pp
+Individual archive entries are written in a three-step
+process:
+You first initialize a
+.Tn struct archive_entry
+structure with information about the new entry.
+At a minimum, you should set the pathname of the
+entry and provide a
+.Va struct stat
+with a valid
+.Va st_mode
+field, which specifies the type of object and
+.Va st_size
+field, which specifies the size of the data portion of the object.
+The
+.Fn archive_write_header
+function actually writes the header data to the archive.
+You can then use
+.Fn archive_write_data
+to write the actual data.
+.Pp
+After all entries have been written, use the
+.Fn archive_write_finish
+function to release all resources.
+.Pp
+The
+.Xr archive_write 3
+manual page provides more detailed calling information for this API.
+.Sh DESCRIPTION
+Detailed descriptions of each function are provided by the
+corresponding manual pages.
+.Pp
+All of the functions utilize an opaque
+.Tn struct archive
+datatype that provides access to the archive contents.
+.Pp
+The
+.Tn struct archive_entry
+structure contains a complete description of a single archive
+entry.
+It uses an opaque interface that is fully documented in
+.Xr archive_entry 3 .
+.Pp
+Users familiar with historic formats should be aware that the newer
+variants have eliminated most restrictions on the length of textual fields.
+Clients should not assume that filenames, link names, user names, or
+group names are limited in length.
+In particular, pax interchange format can easily accommodate pathnames
+in arbitrary character sets that exceed
+.Va PATH_MAX .
+.Sh RETURN VALUES
+Most functions return zero on success, non-zero on error.
+The return value indicates the general severity of the error, ranging
+from
+.Cm ARCHIVE_WARN ,
+which indicates a minor problem that should probably be reported
+to the user, to
+.Cm ARCHIVE_FATAL ,
+which indicates a serious problem that will prevent any further
+operations on this archive.
+On error, the
+.Fn archive_errno
+function can be used to retrieve a numeric error code (see
+.Xr errno 2 ) .
+The
+.Fn archive_error_string
+returns a textual error message suitable for display.
+.Pp
+.Fn archive_read_new
+and
+.Fn archive_write_new
+return pointers to an allocated and initialized
+.Tn struct archive
+object.
+.Pp
+.Fn archive_read_data
+and
+.Fn archive_write_data
+return a count of the number of bytes actually read or written.
+A value of zero indicates the end of the data for this entry.
+A negative value indicates an error, in which case the
+.Fn archive_errno
+and
+.Fn archive_error_string
+functions can be used to obtain more information.
+.Sh ENVIRONMENT
+There are character set conversions within the
+.Xr archive_entry 3
+functions that are impacted by the currently-selected locale.
+.Sh SEE ALSO
+.Xr tar 1 ,
+.Xr archive_entry 3 ,
+.Xr archive_read 3 ,
+.Xr archive_util 3 ,
+.Xr archive_write 3 ,
+.Xr tar 5
+.Sh HISTORY
+The
+.Nm libarchive
+library first appeared in
+.Fx 5.3 .
+.Sh AUTHORS
+.An -nosplit
+The
+.Nm libarchive
+library was written by
+.An Tim Kientzle Aq kientzle@acm.org .
+.Sh BUGS
+Some archive formats support information that is not supported by
+.Tn struct archive_entry .
+Such information cannot be fully archived or restored using this library.
+This includes, for example, comments, character sets,
+or the arbitrary key/value pairs that can appear in
+pax interchange format archives.
+.Pp
+Conversely, of course, not all of the information that can be
+stored in an
+.Tn struct archive_entry
+is supported by all formats.
+For example, cpio formats do not support nanosecond timestamps;
+old tar formats do not support large device numbers.

+.Dt LIBARCHIVE 3
+.Os
+.Sh NAME
+.Nm libarchive_internals
+.Nd description of libarchive internal interfaces
+.Sh OVERVIEW
+The
+.Nm libarchive
+library provides a flexible interface for reading and writing
+streaming archive files such as tar and cpio.
+Internally, it follows a modular layered design that should
+make it easy to add new archive and compression formats.
+.Sh GENERAL ARCHITECTURE
+Externally, libarchive exposes most operations through an
+opaque, object-style interface.
+The
+.Xr archive_entry 1
+objects store information about a single filesystem object.
+The rest of the library provides facilities to write
+.Xr archive_entry 1
+objects to archive files,
+read them from archive files,
+and write them to disk.
+(There are plans to add a facility to read
+.Xr archive_entry 1
+objects from disk as well.)
+.Pp
+The read and write APIs each have four layers: a public API
+layer, a format layer that understands the archive file format,
+a compression layer, and an I/O layer.
+The I/O layer is completely exposed to clients who can replace
+it entirely with their own functions.
+.Pp
+In order to provide as much consistency as possible for clients,
+some public functions are virtualized.
+Eventually, it should be possible for clients to open
+an archive or disk writer, and then use a single set of
+code to select and write entries, regardless of the target.
+.Sh READ ARCHITECTURE
+From the outside, clients use the
+.Xr archive_read 3
+API to manipulate an
+.Nm archive
+object to read entries and bodies from an archive stream.
+Internally, the
+.Nm archive
+object is cast to an
+.Nm archive_read
+object, which holds all read-specific data.
+The API has four layers:
+The lowest layer is the I/O layer.
+This layer can be overridden by clients, but most clients use
+the packaged I/O callbacks provided, for example, by
+.Xr archive_read_open_memory 3 ,
+and
+.Xr archive_read_open_fd 3 .
+The compression layer calls the I/O layer to
+read bytes and decompresses them for the format layer.
+The format layer unpacks a stream of uncompressed bytes and
+creates
+.Nm archive_entry
+objects from the incoming data.
+The API layer tracks overall state
+(for example, it prevents clients from reading data before reading a header)
+and invokes the format and compression layer operations
+through registered function pointers.
+In particular, the API layer drives the format-detection process:
+When opening the archive, it reads an initial block of data
+and offers it to each registered compression handler.
+The one with the highest bid is initialized with the first block.
+Similarly, the format handlers are polled to see which handler
+is the best for each archive.
+(Prior to 2.4.0, the format bidders were invoked for each
+entry, but this design hindered error recovery.)
+.Ss I/O Layer and Client Callbacks
+The read API goes to some lengths to be nice to clients.
+As a result, there are few restrictions on the behavior of
+the client callbacks.
+.Pp
+The client read callback is expected to provide a block
+of data on each call.
+A zero-length return does indicate end of file, but otherwise
+blocks may be as small as one byte or as large as the entire file.
+In particular, blocks may be of different sizes.
+.Pp
+The client skip callback returns the number of bytes actually
+skipped, which may be much smaller than the skip requested.
+The only requirement is that the skip not be larger.
+In particular, clients are allowed to return zero for any
+skip that they don't want to handle.
+The skip callback must never be invoked with a negative value.
+.Pp
+Keep in mind that not all clients are reading from disk:
+clients reading from networks may provide different-sized
+blocks on every request and cannot skip at all;
+advanced clients may use
+.Xr mmap 2
+to read the entire file into memory at once and return the
+entire file to libarchive as a single block;
+other clients may begin asynchronous I/O operations for the
+next block on each request.
+.Ss Decompresssion Layer
+The decompression layer not only handles decompression,
+it also buffers data so that the format handlers see a
+much nicer I/O model.
+The decompression API is a two stage peek/consume model.
+A read_ahead request specifies a minimum read amount;
+the decompression layer must provide a pointer to at least
+that much data.
+If more data is immediately available, it should return more:
+the format layer handles bulk data reads by asking for a minimum
+of one byte and then copying as much data as is available.
+.Pp
+A subsequent call to the
+.Fn consume
+function advances the read pointer.
+Note that data returned from a
+.Fn read_ahead
+call is guaranteed to remain in place until
+the next call to
+.Fn read_ahead .
+Intervening calls to
+.Fn consume
+should not cause the data to move.
+.Pp
+Skip requests must always be handled exactly.
+Decompression handlers that cannot seek forward should
+not register a skip handler;
+the API layer fills in a generic skip handler that reads and discards data.
+.Pp
+A decompression handler has a specific lifecycle:
+.Bl -tag -compact -width indent
+.It Registration/Configuration
+When the client invokes the public support function,
+the decompression handler invokes the internal
+.Fn __archive_read_register_compression
+function to provide bid and initialization functions.
+This function returns
+.Cm NULL
+on error or else a pointer to a
+.Cm struct decompressor_t .
+This structure contains a
+.Va void * config
+slot that can be used for storing any customization information.
+.It Bid
+The bid function is invoked with a pointer and size of a block of data.
+The decompressor can access its config data
+through the
+.Va decompressor
+element of the
+.Cm archive_read
+object.
+The bid function is otherwise stateless.
+In particular, it must not perform any I/O operations.
+.Pp
+The value returned by the bid function indicates its suitability
+for handling this data stream.
+A bid of zero will ensure that this decompressor is never invoked.
+Return zero if magic number checks fail.
+Otherwise, your initial implementation should return the number of bits
+actually checked.
+For example, if you verify two full bytes and three bits of another
+byte, bid 19.
+Note that the initial block may be very short;
+be careful to only inspect the data you are given.
+(The current decompressors require two bytes for correct bidding.)
+.It Initialize
+The winning bidder will have its init function called.
+This function should initialize the remaining slots of the
+.Va struct decompressor_t
+object pointed to by the
+.Va decompressor
+element of the
+.Va archive_read
+object.
+In particular, it should allocate any working data it needs
+in the
+.Va data
+slot of that structure.
+The init function is called with the block of data that
+was used for tasting.
+At this point, the decompressor is responsible for all I/O
+requests to the client callbacks.
+The decompressor is free to read more data as and when
+necessary.
+.It Satisfy I/O requests
+The format handler will invoke the
+.Va read_ahead ,
+.Va consume ,
+and
+.Va skip
+functions as needed.
+.It Finish
+The finish method is called only once when the archive is closed.
+It should release anything stored in the
+.Va data
+and
+.Va config
+slots of the
+.Va decompressor
+object.
+It should not invoke the client close callback.
+.El
+.Ss Format Layer
+The read formats have a similar lifecycle to the decompression handlers:
+.Bl -tag -compact -width indent
+.It Registration
+Allocate your private data and initialize your pointers.
+.It Bid
+Formats bid by invoking the
+.Fn read_ahead
+decompression method but not calling the
+.Fn consume
+method.
+This allows each bidder to look ahead in the input stream.
+Bidders should not look further ahead than necessary, as long
+look aheads put pressure on the decompression layer to buffer
+lots of data.
+Most formats only require a few hundred bytes of look ahead;
+look aheads of a few kilobytes are reasonable.
+(The ISO9660 reader sometimes looks ahead by 48k, which
+should be considered an upper limit.)
+.It Read header
+The header read is usually the most complex part of any format.
+There are a few strategies worth mentioning:
+For formats such as tar or cpio, reading and parsing the header is
+straightforward since headers alternate with data.
+For formats that store all header data at the beginning of the file,
+the first header read request may have to read all headers into
+memory and store that data, sorted by the location of the file
+data.
+Subsequent header read requests will skip forward to the
+beginning of the file data and return the corresponding header.
+.It Read Data
+The read data interface supports sparse files; this requires that
+each call return a block of data specifying the file offset and
+size.
+This may require you to carefully track the location so that you
+can return accurate file offsets for each read.
+Remember that the decompressor will return as much data as it has.
+Generally, you will want to request one byte,
+examine the return value to see how much data is available, and
+possibly trim that to the amount you can use.
+You should invoke consume for each block just before you return it.
+.It Skip All Data
+The skip data call should skip over all file data and trailing padding.
+This is called automatically by the API layer just before each
+header read.
+It is also called in response to the client calling the public
+.Fn data_skip
+function.
+.It Cleanup
+On cleanup, the format should release all of its allocated memory.
+.El
+.Ss API Layer
+XXX to do XXX
+.Sh WRITE ARCHITECTURE
+The write API has a similar set of four layers:
+an API layer, a format layer, a compression layer, and an I/O layer.
+The registration here is much simpler because only
+one format and one compression can be registered at a time.
+.Ss I/O Layer and Client Callbacks
+XXX To be written XXX
+.Ss Compression Layer
+XXX To be written XXX
+.Ss Format Layer
+XXX To be written XXX
+.Ss API Layer
+XXX To be written XXX
+.Sh WRITE_DISK ARCHITECTURE
+The write_disk API is intended to look just like the write API
+to clients.
+Since it does not handle multiple formats or compression, it
+is not layered internally.
+.Sh GENERAL SERVICES
+The
+.Nm archive_read ,
+.Nm archive_write ,
+and
+.Nm archive_write_disk
+objects all contain an initial
+.Nm archive
+object which provides common support for a set of standard services.
+(Recall that ANSI/ISO C90 guarantees that you can cast freely between
+a pointer to a structure and a pointer to the first element of that
+structure.)
+The
+.Nm archive
+object has a magic value that indicates which API this object
+is associated with,
+slots for storing error information,
+and function pointers for virtualized API functions.
+.Sh MISCELLANEOUS NOTES
+Connecting existing archiving libraries into libarchive is generally
+quite difficult.
+In particular, many existing libraries strongly assume that you
+are reading from a file; they seek forwards and backwards as necessary
+to locate various pieces of information.
+In contrast, libarchive never seeks backwards in its input, which
+sometimes requires very different approaches.
+.Pp
+For example, libarchive's ISO9660 support operates very differently
+from most ISO9660 readers.
+The libarchive support utilizes a work-queue design that
+keeps a list of known entries sorted by their location in the input.
+Whenever libarchive's ISO9660 implementation is asked for the next
+header, checks this list to find the next item on the disk.
+Directories are parsed when they are encountered and new
+items are added to the list.
+This design relies heavily on the ISO9660 image being optimized so that
+directories always occur earlier on the disk than the files they
+describe.
+.Pp
+Depending on the specific format, such approaches may not be possible.
+The ZIP format specification, for example, allows archivers to store
+key information only at the end of the file.
+In theory, it is possible to create ZIP archives that cannot
+be read without seeking.
+Fortunately, such archives are very rare, and libarchive can read
+most ZIP archives, though it cannot always extract as much information
+as a dedicated ZIP program.

+.Sh NAME
+.Nm mtree
+.Nd format of mtree dir hierarchy files
+.Sh DESCRIPTION
+The
+.Nm
+format is a textual format that describes a collection of filesystem objects.
+Such files are typically used to create or verify directory hierarchies.
+.Ss General Format
+An
+.Nm
+file consists of a series of lines, each providing information
+about a single filesystem object.
+Leading whitespace is always ignored.
+.Pp
+When encoding file or pathnames, any backslash character or
+character outside of the 95 printable ASCII characters must be
+encoded as a a backslash followed by three
+octal digits.
+When reading mtree files, any appearance of a backslash
+followed by three octal digits should be converted into the
+corresponding character.
+.Pp
+Each line is interpreted independently as one of the following types:
+.Bl -tag -width Cm
+.It Signature
+The first line of any mtree file must begin with
+.Dq #mtree .
+If a file contains any full path entries, the first line should
+begin with
+.Dq #mtree v2.0 ,
+otherwise, the first line should begin with
+.Dq #mtree v1.0 .
+.It Blank
+Blank lines are ignored.
+.It Comment
+Lines beginning with
+.Cm #
+are ignored.
+.It Special
+Lines beginning with
+.Cm /
+are special commands that influence
+the interpretation of later lines.
+.It Relative
+If the first whitespace-delimited word has no
+.Cm /
+characters,
+it is the name of a file in the current directory.
+Any relative entry that describes a directory changes the
+current directory.
+.It dot-dot
+As a special case, a relative entry with the filename
+.Pa ..
+changes the current directory to the parent directory.
+Options on dot-dot entries are always ignored.
+.It Full
+If the first whitespace-delimited word has a
+.Cm /
+character after
+the first character, it is the pathname of a file relative to the
+starting directory.
+There can be multiple full entries describing the same file.
+.El
+.Pp
+Some tools that process
+.Nm
+files may require that multiple lines describing the same file
+occur consecutively.
+It is not permitted for the same file to be mentioned using
+both a relative and a full file specification.
+.Ss Special commands
+Two special commands are currently defined:
+.Bl -tag -width Cm
+.It Cm /set
+This command defines default values for one or more keywords.
+It is followed on the same line by one or more whitespace-separated
+keyword definitions.
+These definitions apply to all following files that do not specify
+a value for that keyword.
+.It Cm /unset
+This command removes any default value set by a previous
+.Cm /set
+command.
+It is followed on the same line by one or more keywords
+separated by whitespace.
+.El
+.Ss Keywords
+After the filename, a full or relative entry consists of zero
+or more whitespace-separated keyword definitions.
+Each such definition consists of a key from the following
+list immediately followed by an '=' sign
+and a value.
+Software programs reading mtree files should warn about
+unrecognized keywords.
+.Pp
+Currently supported keywords are as follows:
+.Bl -tag -width Cm
+.It Cm cksum
+The checksum of the file using the default algorithm specified by
+the
+.Xr cksum 1
+utility.
+.It Cm contents
+The full pathname of a file that holds the contents of this file.
+.It Cm flags
+The file flags as a symbolic name.
+See
+.Xr chflags 1
+for information on these names.
+If no flags are to be set the string
+.Dq none
+may be used to override the current default.
+.It Cm gid
+The file group as a numeric value.
+.It Cm gname
+The file group as a symbolic name.
+.It Cm ignore
+Ignore any file hierarchy below this file.
+.It Cm link
+The target of the symbolic link when type=link.
+.It Cm md5
+The MD5 message digest of the file.
+.It Cm md5digest
+A synonym for
+.Cm md5 .
+.It Cm mode
+The current file's permissions as a numeric (octal) or symbolic
+value.
+.It Cm nlink
+The number of hard links the file is expected to have.
+.It Cm nochange
+Make sure this file or directory exists but otherwise ignore all attributes.

+.Sh NAME
+.Nm tar
+.Nd format of tape archive files
+.Sh DESCRIPTION
+The
+.Nm
+archive format collects any number of files, directories, and other
+file system objects (symbolic links, device nodes, etc.) into a single
+stream of bytes.
+The format was originally designed to be used with
+tape drives that operate with fixed-size blocks, but is widely used as
+a general packaging mechanism.
+.Ss General Format
+A
+.Nm
+archive consists of a series of 512-byte records.
+Each file system object requires a header record which stores basic metadata
+(pathname, owner, permissions, etc.) and zero or more records containing any
+file data.
+The end of the archive is indicated by two records consisting
+entirely of zero bytes.
+.Pp
+For compatibility with tape drives that use fixed block sizes,
+programs that read or write tar files always read or write a fixed
+number of records with each I/O operation.
+These
+.Dq blocks
+are always a multiple of the record size.
+The maximum block size supported by early
+implementations was 10240 bytes or 20 records.
+This is still the default for most implementations
+although block sizes of 1MiB (2048 records) or larger are
+commonly used with modern high-speed tape drives.
+(Note: the terms
+.Dq block
+and
+.Dq record
+here are not entirely standard; this document follows the
+convention established by John Gilmore in documenting
+.Nm pdtar . )
+.Ss Old-Style Archive Format
+The original tar archive format has been extended many times to
+include additional information that various implementors found
+necessary.
+This section describes the variant implemented by the tar command
+included in
+.At v7 ,
+which seems to be the earliest widely-used version of the tar program.
+.Pp
+The header record for an old-style
+.Nm
+archive consists of the following:
+.Bd -literal -offset indent
+struct header_old_tar {
+       char name[100];
+       char mode[8];
+       char uid[8];
+       char gid[8];
+       char size[12];
+       char mtime[12];
+       char checksum[8];
+       char linkflag[1];
+       char linkname[100];
+       char pad[255];
+};
+.Ed
+All unused bytes in the header record are filled with nulls.
+.Bl -tag -width indent
+.It Va name
+Pathname, stored as a null-terminated string.
+Early tar implementations only stored regular files (including
+hardlinks to those files).
+One common early convention used a trailing "/" character to indicate
+a directory name, allowing directory permissions and owner information
+to be archived and restored.
+.It Va mode
+File mode, stored as an octal number in ASCII.
+.It Va uid , Va gid
+User id and group id of owner, as octal numbers in ASCII.
+.It Va size
+Size of file, as octal number in ASCII.
+For regular files only, this indicates the amount of data
+that follows the header.
+In particular, this field was ignored by early tar implementations
+when extracting hardlinks.
+Modern writers should always store a zero length for hardlink entries.
+.It Va mtime
+Modification time of file, as an octal number in ASCII.
+This indicates the number of seconds since the start of the epoch,
+00:00:00 UTC January 1, 1970.
+Note that negative values should be avoided
+here, as they are handled inconsistently.
+.It Va checksum
+Header checksum, stored as an octal number in ASCII.
+To compute the checksum, set the checksum field to all spaces,
+then sum all bytes in the header using unsigned arithmetic.
+This field should be stored as six octal digits followed by a null and a space
+character.
+Note that many early implementations of tar used signed arithmetic
+for the checksum field, which can cause interoperability problems
+when transferring archives between systems.
+Modern robust readers compute the checksum both ways and accept the
+header if either computation matches.
+.It Va linkflag , Va linkname
+In order to preserve hardlinks and conserve tape, a file
+with multiple links is only written to the archive the first
+time it is encountered.
+The next time it is encountered, the
+.Va linkflag
+is set to an ASCII
+.Sq 1
+and the
+.Va linkname
+field holds the first name under which this file appears.
+(Note that regular files have a null value in the
+.Va linkflag
+field.)
+.El
+.Pp
+Early tar implementations varied in how they terminated these fields.
+The tar command in
+.At v7
+used the following conventions (this is also documented in early BSD manpages):
+the pathname must be null-terminated;
+the mode, uid, and gid fields must end in a space and a null byte;
+the size and mtime fields must end in a space;
+the checksum is terminated by a null and a space.
+Early implementations filled the numeric fields with leading spaces.
+This seems to have been common practice until the
+.St -p1003.1-88
+standard was released.
+For best portability, modern implementations should fill the numeric
+fields with leading zeros.
+.Ss Pre-POSIX Archives
+An early draft of
+.St -p1003.1-88
+served as the basis for John Gilmore's
+.Nm pdtar
+program and many system implementations from the late 1980s
+and early 1990s.
+These archives generally follow the POSIX ustar
+format described below with the following variations:
+.Bl -bullet -compact -width indent
+.It
+The magic value is
+.Dq ustar\ \&
+(note the following space).
+The version field contains a space character followed by a null.
+.It
+The numeric fields are generally filled with leading spaces
+(not leading zeros as recommended in the final standard).
+.It
+The prefix field is often not used, limiting pathnames to
+the 100 characters of old-style archives.
+.El
+.Ss POSIX ustar Archives
+.St -p1003.1-88
+defined a standard tar file format to be read and written
+by compliant implementations of
+.Xr tar 1 .
+This format is often called the
+.Dq ustar
+format, after the magic value used
+in the header.
+(The name is an acronym for
+.Dq Unix Standard TAR . )
+It extends the historic format with new fields:
+.Bd -literal -offset indent
+struct header_posix_ustar {
+       char name[100];
+       char mode[8];
+       char uid[8];
+       char gid[8];
+       char size[12];
+       char mtime[12];
+       char checksum[8];
+       char typeflag[1];
+       char linkname[100];
+       char magic[6];
+       char version[2];
+       char uname[32];
+       char gname[32];
+       char devmajor[8];
+       char devminor[8];
+       char prefix[155];
+       char pad[12];
+};
+.Ed
+.Bl -tag -width indent
+.It Va typeflag
+Type of entry.
+POSIX extended the earlier
+.Va linkflag
+field with several new type values:
+.Bl -tag -width indent -compact
+.It Dq 0
+Regular file.
+NUL should be treated as a synonym, for compatibility purposes.
+.It Dq 1
+Hard link.
+.It Dq 2
+Symbolic link.
+.It Dq 3
+Character device node.
+.It Dq 4
+Block device node.
+.It Dq 5
+Directory.
+.It Dq 6
+FIFO node.
+.It Dq 7
+Reserved.
+.It Other
+A POSIX-compliant implementation must treat any unrecognized typeflag value
+as a regular file.
+In particular, writers should ensure that all entries
+have a valid filename so that they can be restored by readers that do not
+support the corresponding extension.
+Uppercase letters "A" through "Z" are reserved for custom extensions.
+Note that sockets and whiteout entries are not archivable.
+.El
+It is worth noting that the
+.Va size
+field, in particular, has different meanings depending on the type.
+For regular files, of course, it indicates the amount of data
+following the header.
+For directories, it may be used to indicate the total size of all
+files in the directory, for use by operating systems that pre-allocate
+directory space.
+For all other types, it should be set to zero by writers and ignored
+by readers.
+.It Va magic
+Contains the magic value
+.Dq ustar
+followed by a NUL byte to indicate that this is a POSIX standard archive.
+Full compliance requires the uname and gname fields be properly set.
+.It Va version
+Version.
+This should be
+.Dq 00
+(two copies of the ASCII digit zero) for POSIX standard archives.
+.It Va uname , Va gname
+User and group names, as null-terminated ASCII strings.
+These should be used in preference to the uid/gid values
+when they are set and the corresponding names exist on
+the system.
+.It Va devmajor , Va devminor
+Major and minor numbers for character device or block device entry.
+.It Va name , Va prefix
+If the pathname is too long to fit in the 100 bytes provided by the standard
+format, it can be split at any
+.Pa /
+character with the first portion going into the prefix field.
+If the prefix field is not empty, the reader will prepend
+the prefix value and a
+.Pa /
+character to the regular name field to obtain the full pathname.
+The standard does not require a trailing
+.Pa /
+character on directory names, though most implementations still
+include this for compatibility reasons.
+.El
+.Pp
+Note that all unused bytes must be set to
+.Dv NUL .
+.Pp
+Field termination is specified slightly differently by POSIX
+than by previous implementations.
+The
+.Va magic ,
+.Va uname ,
+and
+.Va gname
+fields must have a trailing
+.Dv NUL .
+The
+.Va pathname ,
+.Va linkname ,
+and
+.Va prefix
+fields must have a trailing
+.Dv NUL
+unless they fill the entire field.
+(In particular, it is possible to store a 256-character pathname if it
+happens to have a
+.Pa /
+as the 156th character.)
+POSIX requires numeric fields to be zero-padded in the front, and requires
+them to be terminated with either space or
+.Dv NUL
+characters.
+.Pp
+Currently, most tar implementations comply with the ustar
+format, occasionally extending it by adding new fields to the
+blank area at the end of the header record.
+.Ss Pax Interchange Format
+There are many attributes that cannot be portably stored in a
+POSIX ustar archive.
+.St -p1003.1-2001
+defined a
+.Dq pax interchange format
+that uses two new types of entries to hold text-formatted
+metadata that applies to following entries.
+Note that a pax interchange format archive is a ustar archive in every
+respect.
+The new data is stored in ustar-compatible archive entries that use the
+.Dq x
+or
+.Dq g
+typeflag.
+In particular, older implementations that do not fully support these
+extensions will extract the metadata into regular files, where the
+metadata can be examined as necessary.
+.Pp
+An entry in a pax interchange format archive consists of one or
+two standard ustar entries, each with its own header and data.
+The first optional entry stores the extended attributes
+for the following entry.
+This optional first entry has an "x" typeflag and a size field that
+indicates the total size of the extended attributes.
+The extended attributes themselves are stored as a series of text-format
+lines encoded in the portable UTF-8 encoding.
+Each line consists of a decimal number, a space, a key string, an equals
+sign, a value string, and a new line.
+The decimal number indicates the length of the entire line, including the
+initial length field and the trailing newline.
+An example of such a field is:
+.Dl 25 ctime=1084839148.1212\en
+Keys in all lowercase are standard keys.
+Vendors can add their own keys by prefixing them with an all uppercase
+vendor name and a period.
+Note that, unlike the historic header, numeric values are stored using
+decimal, not octal.
+A description of some common keys follows:
+.Bl -tag -width indent
+.It Cm atime , Cm ctime , Cm mtime
+File access, inode change, and modification times.
+These fields can be negative or include a decimal point and a fractional value.
+.It Cm uname , Cm uid , Cm gname , Cm gid
+User name, group name, and numeric UID and GID values.
+The user name and group name stored here are encoded in UTF8
+and can thus include non-ASCII characters.
+The UID and GID fields can be of arbitrary length.
+.It Cm linkpath
+The full path of the linked-to file.
+Note that this is encoded in UTF8 and can thus include non-ASCII characters.
+.It Cm path
+The full pathname of the entry.
+Note that this is encoded in UTF8 and can thus include non-ASCII characters.
+.It Cm realtime.* , Cm security.*
+These keys are reserved and may be used for future standardization.
+.It Cm size
+The size of the file.
+Note that there is no length limit on this field, allowing conforming
+archives to store files much larger than the historic 8GB limit.
+.It Cm SCHILY.*
+Vendor-specific attributes used by Joerg Schilling's
+.Nm star
+implementation.
+.It Cm SCHILY.acl.access , Cm SCHILY.acl.default
+Stores the access and default ACLs as textual strings in a format
+that is an extension of the format specified by POSIX.1e draft 17.
+In particular, each user or group access specification can include a fourth
+colon-separated field with the numeric UID or GID.
+This allows ACLs to be restored on systems that may not have complete
+user or group information available (such as when NIS/YP or LDAP services
+are temporarily unavailable).
+.It Cm SCHILY.devminor , Cm SCHILY.devmajor
+The full minor and major numbers for device nodes.
+.It Cm SCHILY.fflags
+The file flags.
+.It Cm SCHILY.realsize
+The full size of the file on disk.
+XXX explain? XXX
+.It Cm SCHILY.dev, Cm SCHILY.ino , Cm SCHILY.nlinks
+The device number, inode number, and link count for the entry.
+In particular, note that a pax interchange format archive using Joerg
+Schilling's
+.Cm SCHILY.*
+extensions can store all of the data from
+.Va struct stat .
+.It Cm LIBARCHIVE.xattr. Ns Ar namespace Ns . Ns Ar key
+Libarchive stores POSIX.1e-style extended attributes using
+keys of this form.
+The
+.Ar key
+value is URL-encoded:
+All non-ASCII characters and the two special characters
+.Dq =
+and
+.Dq %
+are encoded as
+.Dq %
+followed by two uppercase hexadecimal digits.
+The value of this key is the extended attribute value
+encoded in base 64.
+XXX Detail the base-64 format here XXX
+.It Cm VENDOR.*
+XXX document other vendor-specific extensions XXX
+.El
+.Pp
+Any values stored in an extended attribute override the corresponding
+values in the regular tar header.
+Note that compliant readers should ignore the regular fields when they
+are overridden.
+This is important, as existing archivers are known to store non-compliant
+values in the standard header fields in this situation.
+There are no limits on length for any of these fields.
+In particular, numeric fields can be arbitrarily large.
+All text fields are encoded in UTF8.
+Compliant writers should store only portable 7-bit ASCII characters in
+the standard ustar header and use extended
+attributes whenever a text value contains non-ASCII characters.
+.Pp
+In addition to the
+.Cm x
+entry described above, the pax interchange format
+also supports a
+.Cm g
+entry.
+The
+.Cm g
+entry is identical in format, but specifies attributes that serve as
+defaults for all subsequent archive entries.
+The
+.Cm g
+entry is not widely used.
+.Pp
+Besides the new
+.Cm x
+and
+.Cm g
+entries, the pax interchange format has a few other minor variations
+from the earlier ustar format.
+The most troubling one is that hardlinks are permitted to have
+data following them.
+This allows readers to restore any hardlink to a file without
+having to rewind the archive to find an earlier entry.
+However, it creates complications for robust readers, as it is no longer
+clear whether or not they should ignore the size field for hardlink entries.
+.Ss GNU Tar Archives
+The GNU tar program started with a pre-POSIX format similar to that
+described earlier and has extended it using several different mechanisms:
+It added new fields to the empty space in the header (some of which was later
+used by POSIX for conflicting purposes);
+it allowed the header to be continued over multiple records;
+and it defined new entries that modify following entries
+(similar in principle to the
+.Cm x
+entry described above, but each GNU special entry is single-purpose,
+unlike the general-purpose
+.Cm x
+entry).
+As a result, GNU tar archives are not POSIX compatible, although
+more lenient POSIX-compliant readers can successfully extract most
+GNU tar archives.

+.Ed
+.Bl -tag -width indent
+.It Va typeflag
+GNU tar uses the following special entry types, in addition to
+those defined by POSIX:
+.Bl -tag -width indent
+.It "7"
+GNU tar treats type "7" records identically to type "0" records,
+except on one obscure RTOS where they are used to indicate the
+pre-allocation of a contiguous file on disk.
+.It "D"
+This indicates a directory entry.
+Unlike the POSIX-standard "5"
+typeflag, the header is followed by data records listing the names
+of files in this directory.
+Each name is preceded by an ASCII "Y"
+if the file is stored in this archive or "N" if the file is not
+stored in this archive.
+Each name is terminated with a null, and
+an extra null marks the end of the name list.
+The purpose of this
+entry is to support incremental backups; a program restoring from
+such an archive may wish to delete files on disk that did not exist
+in the directory when the archive was made.
+.Pp
+Note that the "D" typeflag specifically violates POSIX, which requires
+that unrecognized typeflags be restored as normal files.
+In this case, restoring the "D" entry as a file could interfere
+with subsequent creation of the like-named directory.
+.It "K"
+The data for this entry is a long linkname for the following regular entry.
+.It "L"
+The data for this entry is a long pathname for the following regular entry.
+.It "M"
+This is a continuation of the last file on the previous volume.
+GNU multi-volume archives guarantee that each volume begins with a valid
+entry header.
+To ensure this, a file may be split, with part stored at the end of one volume,
+and part stored at the beginning of the next volume.
+The "M" typeflag indicates that this entry continues an existing file.
+Such entries can only occur as the first or second entry
+in an archive (the latter only if the first entry is a volume label).
+The
+.Va size
+field specifies the size of this entry.
+The
+.Va offset
+field at bytes 369-380 specifies the offset where this file fragment
+begins.
+The
+.Va realsize
+field specifies the total size of the file (which must equal
+.Va size
+plus
+.Va offset ) .
+When extracting, GNU tar checks that the header file name is the one it is
+expecting, that the header offset is in the correct sequence, and that
+the sum of offset and size is equal to realsize.
+.It "N"
+Type "N" records are no longer generated by GNU tar.
+They contained a
+list of files to be renamed or symlinked after extraction; this was
+originally used to support long names.
+The contents of this record
+are a text description of the operations to be done, in the form
+.Dq Rename %s to %s\en
+or
+.Dq Symlink %s to %s\en ;
+in either case, both
+filenames are escaped using K&R C syntax.
+Due to security concerns, "N" records are now generally ignored
+when reading archives.
+.It "S"
+This is a
+.Dq sparse
+regular file.
+Sparse files are stored as a series of fragments.
+The header contains a list of fragment offset/length pairs.
+If more than four such entries are required, the header is
+extended as necessary with
+.Dq extra
+header extensions (an older format that is no longer used), or
+.Dq sparse
+extensions.
+.It "V"
+The
+.Va name
+field should be interpreted as a tape/volume header name.
+This entry should generally be ignored on extraction.
+.El
+.It Va magic
+The magic field holds the five characters
+.Dq ustar
+followed by a space.
+Note that POSIX ustar archives have a trailing null.
+.It Va version
+The version field holds a space character followed by a null.
+Note that POSIX ustar archives use two copies of the ASCII digit
+.Dq 0 .
+.It Va atime , Va ctime
+The time the file was last accessed and the time of
+last change of file information, stored in octal as with
+.Va mtime .
+.It Va longnames
+This field is apparently no longer used.
+.It Sparse Va offset / Va numbytes
+Each such structure specifies a single fragment of a sparse
+file.
+The two fields store values as octal numbers.
+The fragments are each padded to a multiple of 512 bytes
+in the archive.
+On extraction, the list of fragments is collected from the
+header (including any extension headers), and the data
+is then read and written to the file at appropriate offsets.
+.It Va isextended
+If this is set to non-zero, the header will be followed by additional
+.Dq sparse header
+records.
+Each such record contains information about as many as 21 additional
+sparse blocks as shown here:
+.Bd -literal -offset indent
+struct gnu_sparse_header {
+       struct {
+               char offset[12];
+               char numbytes[12];
+       } sparse[21];
+       char    isextended[1];
+       char    padding[7];
+};
+.Ed
+.It Va realsize
+A binary representation of the file's complete size, with a much larger range
+than the POSIX file size.
+In particular, with
+.Cm M
+type files, the current entry is only a portion of the file.
+In that case, the POSIX size field will indicate the size of this
+entry; the
+.Va realsize
+field will indicate the total size of the file.
+.El
+.Ss GNU tar pax archives
+GNU tar 1.14 (XXX check this XXX) and later will write
+pax interchange format archives when you specify the
+.Fl -posix
+flag.
+This format uses custom keywords to store sparse file information.
+There have been three iterations of this support, referred to
+as
+.Dq 0.0 ,
+.Dq 0.1 ,
+and
+.Dq 1.0 .
+.Bl -tag -width indent
+.It Cm GNU.sparse.numblocks , Cm GNU.sparse.offset , Cm GNU.sparse.numbytes , Cm  GNU.sparse.size
+The
+.Dq 0.0
+format used an initial
+.Cm GNU.sparse.numblocks
+attribute to indicate the number of blocks in the file, a pair of
+.Cm GNU.sparse.offset
+and
+.Cm GNU.sparse.numbytes
+to indicate the offset and size of each block,
+and a single
+.Cm GNU.sparse.size
+to indicate the full size of the file.
+This is not the same as the size in the tar header because the
+latter value does not include the size of any holes.
+This format required that the order of attributes be preserved and
+relied on readers accepting multiple appearances of the same attribute
+names, which is not officially permitted by the standards.
+.It Cm GNU.sparse.map
+The
+.Dq 0.1
+format used a single attribute that stored a comma-separated
+list of decimal numbers.
+Each pair of numbers indicated the offset and size, respectively,
+of a block of data.
+This does not work well if the archive is extracted by an archiver
+that does not recognize this extension, since many pax implementations
+simply discard unrecognized attributes.
+.It Cm GNU.sparse.major , Cm GNU.sparse.minor , Cm GNU.sparse.name , Cm GNU.sparse.realsize
+The
+.Dq 1.0
+format stores the sparse block map in one or more 512-byte blocks
+prepended to the file data in the entry body.
+The pax attributes indicate the existence of this map
+(via the
+.Cm GNU.sparse.major
+and
+.Cm GNU.sparse.minor
+fields)
+and the full size of the file.
+The
+.Cm GNU.sparse.name
+holds the true name of the file.
+To avoid confusion, the name stored in the regular tar header
+is a modified name so that extraction errors will be apparent
+to users.
+.El
+.Ss Solaris Tar
+XXX More Details Needed XXX
+.Pp
+Solaris tar (beginning with SunOS XXX 5.7 ?? XXX) supports an
+.Dq extended
+format that is fundamentally similar to pax interchange format,
+with the following differences:
+.Bl -bullet -compact -width indent
+.It
+Extended attributes are stored in an entry whose type is
+.Cm X ,
+not
+.Cm x ,
+as used by pax interchange format.
+The detailed format of this entry appears to be the same
+as detailed above for the
+.Cm x
+entry.
+.It
+An additional
+.Cm A
+entry is used to store an ACL for the following regular entry.
+The body of this entry contains a seven-digit octal number
+followed by a zero byte, followed by the
+textual ACL description.
+The octal value is the number of ACL entries
+plus a constant that indicates the ACL type: 01000000
+for POSIX.1e ACLs and 03000000 for NFSv4 ACLs.
+.El
+.Ss AIX Tar
+XXX More details needed XXX
+.Ss Mac OS X Tar
+The tar distributed with Apple's Mac OS X stores most regular files
+as two separate entries in the tar archive.
+The two entries have the same name except that the first
+one has
+.Dq ._
+added to the beginning of the name.
+This first entry stores the
+.Dq resource fork
+with additional attributes for the file.
+The Mac OS X
+.Fn CopyFile
+API is used to separate a file on disk into separate
+resource and data streams and to reassemble those separate
+streams when the file is restored to disk.
+.Ss Other Extensions
+One obvious extension to increase the size of files is to
+eliminate the terminating characters from the various
+numeric fields.
+For example, the standard only allows the size field to contain
+11 octal digits, reserving the twelfth byte for a trailing
+NUL character.
+Allowing 12 octal digits allows file sizes up to 64 GB.
+.Pp
+Another extension, utilized by GNU tar, star, and other newer
+.Nm
+implementations, permits binary numbers in the standard numeric fields.
+This is flagged by setting the high bit of the first byte.
+This permits 95-bit values for the length and time fields
+and 63-bit values for the uid, gid, and device numbers.
+GNU tar supports this extension for the
+length, mtime, ctime, and atime fields.
+Joerg Schilling's star program supports this extension for
+all numeric fields.
+Note that this extension is largely obsoleted by the extended attribute
+record provided by the pax interchange format.
+.Pp
+Another early GNU extension allowed base-64 values rather than octal.
+This extension was short-lived and is no longer supported by any
+implementation.

+$FreeBSD: src/lib/libarchive/test/README,v 1.3 2008/01/01 22:28:04 kientzle Exp $
+
+This is the test harness for libarchive.
+
+It compiles into a single program "libarchive_test" that is intended
+to exercise as much of the library as possible.  It is, of course,
+very much a work in progress.
+
+Each test is a function named test_foo in a file named test_foo.c.
+Note that the file name is the same as the function name.
+Each file must start with this line:
+
+  #include "test.h"
+
+The test function must be declared with a line of this form
+
+  DEFINE_TEST(test_foo)
+
+Nothing else should appear on that line.
+
+When you add a test, please update the Makefile to add your
+file to the list of tests.  The Makefile and main.c use various
+macro trickery to automatically collect a list of test functions
+to be invoked.
+
+Each test function can rely on the following:
+
+  * The current directory will be a freshly-created empty directory
+    suitable for that test.  (The top-level main() creates a
+    directory for each separate test and chdir()s to that directory
+    before running the test.)
+
+  * The test function should use assert(), assertA() and similar macros
+    defined in test.h.  If you need to add new macros of this form, feel
+    free to do so.  The current macro set includes assertEqualInt() and
+    assertEqualString() that print out additional detail about their
+    arguments if the assertion does fail.  'A' versions also accept
+    a struct archive * and display any error message from there on
+    failure.
+
+  * You are encouraged to document each assertion with a failure() call
+    just before the assert.  The failure() function is a printf-like
+    function whose text is displayed only if the assertion fails.  It
+    can be used to display additional information relevant to the failure:
+
+       failure("The data read from file %s did not match the data written to that file.", filename);
+       assert(strcmp(buff1, buff2) == 0);
+
+  * Tests are encouraged to be economical with their memory and disk usage,
+    though this is not essential.  The test is occasionally run under
+    a memory debugger to try to locate memory leaks in the library;
+    as a result, tests should be careful to release any memory they
+    allocate.
+
+  * Disable tests on specific platforms as necessary.  Please don't
+    use config.h to adjust feature requirements, as I want the tests
+    to also serve as a check on the configure process.  The following
+    form is appropriate:
+
+#if !defined(__PLATFORM) && !defined(__Platform2__)
+    assert(xxxx)
+#endif

+ * Background:  There are two written standards for the tar file format.
+ * The first is the POSIX 1988 "ustar" format, the second is the 2001
+ * "pax extended" format that builds on the "ustar" format by adding
+ * support for generic additional attributes.  Buried in the details
+ * is one frustrating incompatibility:  The 1988 standard says that
+ * tar readers MUST ignore the size field on hardlink entries; the
+ * 2001 standard says that tar readers MUST obey the size field on
+ * hardlink entries.  libarchive tries to navigate this particular
+ * minefield by using auto-detect logic to guess whether it should
+ * or should not obey the size field.
+ *
+ * This test tries to probe the boundaries of such handling; the test
+ * archives here were adapted from real archives created by real
+ * tar implementations that are (as of early 2008) apparently still
+ * in use.

+ *    http://seclists.org/vulnwatch/2005/q1/0088.html
+ *
+ * This test simply reads each archive image into memory, pokes
+ * random values into it and runs it through libarchive.  It tries
+ * to damage about 1% of each file and repeats the exercise 100 times
+ * with each file.
+ *
+ * Unlike most other tests, this test does not verify libarchive's
+ * responses other than to ensure that libarchive doesn't crash.
+ *
+ * Due to the deliberately random nature of this test, it may be hard
+ * to reproduce failures.  Because this test deliberately attempts to
+ * induce crashes, there's little that can be done in the way of
+ * post-failure diagnostics.

+.Sh DESCRIPTION
+.Nm
+creates and manipulates streaming archive files.
+This implementation can extract from tar, pax, cpio, zip, jar, ar,
+and ISO 9660 cdrom images and can create tar, pax, cpio, ar,
+and shar archives.
+.Pp
+The first synopsis form shows a
+.Dq bundled
+option word.
+This usage is provided for compatibility with historical implementations.
+See COMPATIBILITY below for details.
+.Pp
+The other synopsis forms show the preferred usage.
+The first option to
+.Nm
+is a mode indicator from the following list:
+.Bl -tag -compact -width indent
+.It Fl c
+Create a new archive containing the specified items.
+.It Fl r
+Like
+.Fl c ,
+but new entries are appended to the archive.
+Note that this only works on uncompressed archives stored in regular files.
+The
+.Fl f
+option is required.
+.It Fl t
+List archive contents to stdout.
+.It Fl u
+Like
+.Fl r ,
+but new entries are added only if they have a modification date
+newer than the corresponding entry in the archive.
+Note that this only works on uncompressed archives stored in regular files.
+The
+.Fl f
+option is required.
+.It Fl x
+Extract to disk from the archive.
+If a file with the same name appears more than once in the archive,
+each copy will be extracted, with later copies overwriting (replacing)
+earlier copies.
+.El
+.Pp
+In
+.Fl c ,
+.Fl r ,
+or
+.Fl u
+mode, each specified file or directory is added to the
+archive in the order specified on the command line.
+By default, the contents of each directory are also archived.
+.Pp
+In extract or list mode, the entire command line
+is read and parsed before the archive is opened.
+The pathnames or patterns on the command line indicate
+which items in the archive should be processed.
+Patterns are shell-style globbing patterns as
+documented in
+.Xr tcsh 1 .
+.Sh OPTIONS
+Unless specifically stated otherwise, options are applicable in
+all operating modes.
+.Bl -tag -width indent
+.It Cm @ Ns Pa archive
+(c and r mode only)
+The specified archive is opened and the entries
+in it will be appended to the current archive.
+As a simple example,
+.Dl Nm Fl c Fl f Pa - Pa newfile Cm @ Ns Pa original.tar
+writes a new archive to standard output containing a file
+.Pa newfile
+and all of the entries from
+.Pa original.tar .
+In contrast,
+.Dl Nm Fl c Fl f Pa - Pa newfile Pa original.tar
+creates a new archive with only two entries.
+Similarly,
+.Dl Nm Fl czf Pa - Fl -format Cm pax Cm @ Ns Pa -
+reads an archive from standard input (whose format will be determined
+automatically) and converts it into a gzip-compressed
+pax-format archive on stdout.
+In this way,
+.Nm
+can be used to convert archives from one format to another.
+.It Fl b Ar blocksize
+Specify the block size, in 512-byte records, for tape drive I/O.
+As a rule, this argument is only needed when reading from or writing
+to tape drives, and usually not even then as the default block size of
+20 records (10240 bytes) is very common.
+.It Fl C Ar directory
+In c and r mode, this changes the directory before adding
+the following files.
+In x mode, change directories after opening the archive
+but before extracting entries from the archive.
+.It Fl -check-links
+(c and r modes only)
+Issue a warning message unless all links to each file are archived.
+.It Fl -chroot
+(x mode only)
+.Fn chroot
+to the current directory after processing any
+.Fl C
+options and before extracting any files.
+.It Fl -exclude Ar pattern
+Do not process files or directories that match the
+specified pattern.
+Note that exclusions take precedence over patterns or filenames
+specified on the command line.
+.It Fl -format Ar format
+(c, r, u mode only)
+Use the specified format for the created archive.
+Supported formats include
+.Dq cpio ,
+.Dq pax ,
+.Dq shar ,
+and
+.Dq ustar .
+Other formats may also be supported; see
+.Xr libarchive-formats 5
+for more information about currently-supported formats.
+In r and u modes, when extending an existing archive, the format specified
+here must be compatible with the format of the existing archive on disk.
+.It Fl f Ar file
+Read the archive from or write the archive to the specified file.
+The filename can be
+.Pa -
+for standard input or standard output.
+If not specified, the default tape device will be used.
+(On
+.Fx ,
+the default tape device is
+.Pa /dev/sa0 . )
+.It Fl H
+(c and r mode only)
+Symbolic links named on the command line will be followed; the
+target of the link will be archived, not the link itself.
+.It Fl h
+(c and r mode only)
+Synonym for
+.Fl L .
+.It Fl I
+Synonym for
+.Fl T .
+.It Fl -include Ar pattern
+Process only files or directories that match the specified pattern.
+Note that exclusions specified with
+.Fl -exclude
+take precedence over inclusions.
+If no inclusions are explicitly specified, all entries are processed by
+default.
+The
+.Fl -include
+option is especially useful when filtering archives.
+For example, the command
+.Dl Nm Fl c Fl f Pa new.tar Fl -include='*foo*' Cm @ Ns Pa old.tgz
+creates a new archive
+.Pa new.tar
+containing only the entries from
+.Pa old.tgz
+containing the string
+.Sq foo .
+.It Fl j
+(c mode only)
+Compress the resulting archive with
+.Xr bzip2 1 .
+In extract or list modes, this option is ignored.
+Note that, unlike other
+.Nm tar
+implementations, this implementation recognizes bzip2 compression
+automatically when reading archives.
+.It Fl k
+(x mode only)
+Do not overwrite existing files.
+In particular, if a file appears more than once in an archive,
+later copies will not overwrite earlier copies.
+.It Fl -keep-newer-files
+(x mode only)
+Do not overwrite existing files that are newer than the
+versions appearing in the archive being extracted.
+.It Fl L
+(c and r mode only)
+All symbolic links will be followed.
+Normally, symbolic links are archived as such.
+With this option, the target of the link will be archived instead.
+.It Fl l
+This is a synonym for the
+.Fl -check-links
+option.
+.It Fl m
+(x mode only)
+Do not extract modification time.
+By default, the modification time is set to the time stored in the archive.
+.It Fl n
+(c, r, u modes only)
+Do not recursively archive the contents of directories.
+.It Fl -newer Ar date
+(c, r, u modes only)
+Only include files and directories newer than the specified date.
+This compares ctime entries.
+.It Fl -newer-mtime Ar date
+(c, r, u modes only)
+Like
+.Fl -newer ,
+except it compares mtime entries instead of ctime entries.
+.It Fl -newer-than Pa file
+(c, r, u modes only)
+Only include files and directories newer than the specified file.
+This compares ctime entries.
+.It Fl -newer-mtime-than Pa file
+(c, r, u modes only)
+Like
+.Fl -newer-than ,
+except it compares mtime entries instead of ctime entries.
+.It Fl -nodump
+(c and r modes only)
+Honor the nodump file flag by skipping this file.
+.It Fl -null
+(use with
+.Fl I ,
+.Fl T ,
+or
+.Fl X )
+Filenames or patterns are separated by null characters,
+not by newlines.
+This is often used to read filenames output by the
+.Fl print0
+option to
+.Xr find 1 .
+.It Fl -numeric-owner
+(x mode only)
+Ignore symbolic user and group names when restoring archives to disk,
+only numeric uid and gid values will be obeyed.
+.It Fl O
+(x, t modes only)
+In extract (-x) mode, files will be written to standard out rather than
+being extracted to disk.
+In list (-t) mode, the file listing will be written to stderr rather than
+the usual stdout.
+.It Fl o
+(x mode)
+Use the user and group of the user running the program rather
+than those specified in the archive.
+Note that this has no significance unless
+.Fl p
+is specified, and the program is being run by the root user.
+In this case, the file modes and flags from
+the archive will be restored, but ACLs or owner information in
+the archive will be discarded.
+.It Fl o
+(c, r, u mode)
+A synonym for
+.Fl -format Ar ustar
+.It Fl -one-file-system
+(c, r, and u modes)
+Do not cross mount points.
+.It Fl -options Ar options
+Select optional behaviors for particular modules.
+The argument is a text string containing comma-separated
+keywords and values.
+These are passed to the modules that handle particular
+formats to control how those formats will behave.
+Each option has one of the following forms:
+.Bl -tag -compact -width indent
+.It Ar key=value
+The key will be set to the specified value in every module that supports it.
+Modules that do not support this key will ignore it.
+.It Ar key
+The key will be enabled in every module that supports it.
+This is equivalent to
+.Ar key Ns Cm =1 .
+.It Ar !key
+The key will be disabled in every module that supports it.
+.It Ar module:key=value , Ar module:key , Ar module:!key
+As above, but the corresponding key and value will be provided
+only to modules whose name matches
+.Ar module .
+.El
+The currently supported modules and keys are:
+.Bl -tag -compact -width indent
+.It Cm iso9660:joliet
+Support Joliet extensions.
+This is enabled by default, use
+.Cm !joliet
+or
+.Cm iso9660:!joliet
+to disable.
+.It Cm iso9660:rockridge
+Support Rock Ridge extensions.
+This is enabled by default, use
+.Cm !rockridge
+or
+.Cm iso9660:!rockridge
+to disable.
+.It Cm gzip:compression-level
+A decimal integer from 0 to 9 specifying the gzip compression level.
+.It Cm xz:compression-level
+A decimal integer from 0 to 9 specifying the xz compression level.
+.It Cm mtree: Ns Ar keyword
+The mtree writer module allows you to specify which mtree keywords
+will be included in the output.
+Supported keywords include:
+.Cm cksum , Cm device , Cm flags , Cm gid , Cm gname , Cm indent ,
+.Cm link , Cm md5 , Cm mode , Cm nlink , Cm rmd160 , Cm sha1 , Cm sha256 ,
+.Cm sha384 , Cm sha512 , Cm size , Cm time , Cm uid , Cm uname .
+The default is equivalent to:
+.Dq device, flags, gid, gname, link, mode, nlink, size, time, type, uid, uname .
+.It Cm mtree:all
+Enables all of the above keywords.
+You can also use
+.Cm mtree:!all
+to disable all keywords.
+.It Cm mtree:use-set
+Enable generation of
+.Cm /set
+lines in the output.
+.It Cm mtree:indent
+Produce human-readable output by indenting options and splitting lines
+to fit into 80 columns.
+.It Cm zip:compression Ns = Ns Ar type
+Use
+.Ar type
+as compression method.
+Supported values are store (uncompressed) and deflate (gzip algorithm).
+.El
+If a provided option is not supported by any module, that
+is a fatal error.
+.It Fl P
+Preserve pathnames.
+By default, absolute pathnames (those that begin with a /
+character) have the leading slash removed both when creating archives
+and extracting from them.
+Also,
+.Nm
+will refuse to extract archive entries whose pathnames contain
+.Pa ..
+or whose target directory would be altered by a symlink.
+This option suppresses these behaviors.
+.It Fl p
+(x mode only)
+Preserve file permissions.
+Attempt to restore the full permissions, including owner, file modes, file
+flags and ACLs, if available, for each item extracted from the archive.
+By default, newly-created files are owned by the user running
+.Nm ,
+the file mode is restored for newly-created regular files, and
+all other types of entries receive default permissions.
+If
+.Nm
+is being run by root, the default is to restore the owner unless the
+.Fl o
+option is also specified.
+.It Fl q ( Fl -fast-read )
+(x and t mode only)
+Extract or list only the first archive entry that matches each pattern
+or filename operand.
+Exit as soon as each specified pattern or filename has been matched.
+By default, the archive is always read to the very end, since
+there can be multiple entries with the same name and, by convention,
+later entries overwrite earlier entries.
+This option is provided as a performance optimization.
+.It Fl S
+(x mode only)
+Extract files as sparse files.
+For every block on disk, check first if it contains only NULL bytes and seek
+over it otherwise.
+This works similiar to the conv=sparse option of dd.
+.It Fl -strip-components Ar count
+(x mode only)
+Remove the specified number of leading path elements.
+Pathnames with fewer elements will be silently skipped.
+Note that the pathname is edited after checking inclusion/exclusion patterns
+but before security checks.
+.It Fl s Ar pattern
+Modify file or archive member names according to
+.Pa pattern .
+The pattern has the format
+.Ar /old/new/ Ns Op gps
+where
+.Ar old
+is a basic regular expression,
+.Ar new
+is the replacement string of the matched part,
+and the optional trailing letters modify
+how the replacement is handled.
+If
+.Ar old
+is not matched, the pattern is skipped.
+Within
+.Ar new ,
+~ is substituted with the match, \1 to \9 with the content of
+the corresponding captured group.
+The optional trailing g specifies that matching should continue
+after the matched part and stopped on the first unmatched pattern.
+The optional trailing s specifies that the pattern applies to the value
+of symbolic links.
+The optional trailing p specifies that after a successful substitution
+the original path name and the new path name should be printed to
+standard error.
+.It Fl T Ar filename
+In x or t mode,
+.Nm
+will read the list of names to be extracted from
+.Pa filename .
+In c mode,
+.Nm
+will read names to be archived from
+.Pa filename .
+The special name
+.Dq -C
+on a line by itself will cause the current directory to be changed to
+the directory specified on the following line.
+Names are terminated by newlines unless
+.Fl -null
+is specified.
+Note that
+.Fl -null
+also disables the special handling of lines containing
+.Dq -C .
+.It Fl U
+(x mode only)
+Unlink files before creating them.
+Without this option,
+.Nm
+overwrites existing files, which preserves existing hardlinks.
+With this option, existing hardlinks will be broken, as will any
+symlink that would affect the location of an extracted file.
+.It Fl -use-compress-program Ar program
+Pipe the input (in x or t mode) or the output (in c mode) through
+.Pa program
+instead of using the builtin compression support.
+.It Fl v
+Produce verbose output.
+In create and extract modes,
+.Nm
+will list each file name as it is read from or written to
+the archive.
+In list mode,
+.Nm
+will produce output similar to that of
+.Xr ls 1 .
+Additional
+.Fl v
+options will provide additional detail.
+.It Fl -version
+Print version of
+.Nm
+and
+.Nm libarchive ,
+and exit.
+.It Fl w
+Ask for confirmation for every action.
+.It Fl X Ar filename
+Read a list of exclusion patterns from the specified file.
+See
+.Fl -exclude
+for more information about the handling of exclusions.
+.It Fl y
+(c mode only)
+Compress the resulting archive with
+.Xr bzip2 1 .
+In extract or list modes, this option is ignored.
+Note that, unlike other
+.Nm tar
+implementations, this implementation recognizes bzip2 compression
+automatically when reading archives.
+.It Fl z
+(c mode only)
+Compress the resulting archive with
+.Xr gzip 1 .
+In extract or list modes, this option is ignored.
+Note that, unlike other
+.Nm tar
+implementations, this implementation recognizes gzip compression
+automatically when reading archives.
+.It Fl Z
+(c mode only)
+Compress the resulting archive with
+.Xr compress 1 .
+In extract or list modes, this option is ignored.
+Note that, unlike other
+.Nm tar
+implementations, this implementation recognizes compress compression
+automatically when reading archives.
+.El
+.Sh ENVIRONMENT
+The following environment variables affect the execution of
+.Nm :
+.Bl -tag -width ".Ev BLOCKSIZE"
+.It Ev LANG
+The locale to use.
+See
+.Xr environ 7
+for more information.
+.It Ev TAPE
+The default tape device.
+The
+.Fl f
+option overrides this.
+.It Ev TZ
+The timezone to use when displaying dates.
+See
+.Xr environ 7
+for more information.
+.El
+.Sh FILES
+.Bl -tag -width ".Ev BLOCKSIZE"
+.It Pa /dev/sa0
+The default tape device, if not overridden by the
+.Ev TAPE
+environment variable or the
+.Fl f
+option.
+.El
+.Sh EXIT STATUS
+.Ex -std
+.Sh EXAMPLES
+The following creates a new archive
+called
+.Ar file.tar.gz
+that contains two files
+.Ar source.c
+and
+.Ar source.h :
+.Dl Nm Fl czf Pa file.tar.gz Pa source.c Pa source.h
+.Pp
+To view a detailed table of contents for this
+archive:
+.Dl Nm Fl tvf Pa file.tar.gz
+.Pp
+To extract all entries from the archive on
+the default tape drive:
+.Dl Nm Fl x
+.Pp
+To examine the contents of an ISO 9660 cdrom image:
+.Dl Nm Fl tf Pa image.iso
+.Pp
+To move file hierarchies, invoke
+.Nm
+as
+.Dl Nm Fl cf Pa - Fl C Pa srcdir\ . | Nm Fl xpf Pa - Fl C Pa destdir
+or more traditionally
+.Dl cd srcdir \&; Nm Fl cf Pa -\ . | ( cd destdir \&; Nm Fl xpf Pa - )
+.Pp
+In create mode, the list of files and directories to be archived
+can also include directory change instructions of the form
+.Cm -C Ns Pa foo/baz
+and archive inclusions of the form
+.Cm @ Ns Pa archive-file .
+For example, the command line
+.Dl Nm Fl c Fl f Pa new.tar Pa foo1 Cm @ Ns Pa old.tgz Cm -C Ns Pa /tmp Pa foo2
+will create a new archive
+.Pa new.tar .
+.Nm
+will read the file
+.Pa foo1
+from the current directory and add it to the output archive.
+It will then read each entry from
+.Pa old.tgz
+and add those entries to the output archive.
+Finally, it will switch to the
+.Pa /tmp
+directory and add
+.Pa foo2
+to the output archive.
+.Pp
+An input file in
+.Xr mtree 5
+format can be used to create an output archive with arbitrary ownership,
+permissions, or names that differ from existing data on disk:
+.Pp
+.Dl $ cat input.mtree
+.Dl #mtree
+.Dl usr/bin uid=0 gid=0 mode=0755 type=dir
+.Dl usr/bin/ls uid=0 gid=0 mode=0755 type=file content=myls
+.Dl $ tar -cvf output.tar @input.mtree
+.Pp
+The
+.Fl -newer
+and
+.Fl -newer-mtime
+switches accept a variety of common date and time specifications, including
+.Dq 12 Mar 2005 7:14:29pm ,
+.Dq 2005-03-12 19:14 ,
+.Dq 5 minutes ago ,
+and
+.Dq 19:14 PST May 1 .
+.Pp
+The
+.Fl -options
+argument can be used to control various details of archive generation
+or reading.
+For example, you can generate mtree output which only contains
+.Cm type , Cm time ,
+and
+.Cm uid
+keywords:
+.Dl Nm Fl cf Pa file.tar Fl -format=mtree Fl -options='!all,type,time,uid' Pa dir
+or you can set the compression level used by gzip or xz compression:
+.Dl Nm Fl czf Pa file.tar Fl -options='compression-level=9' .
+For more details, see the explanation of the
+.Fn archive_read_set_options
+and
+.Fn archive_write_set_options
+API calls that are described in
+.Xr archive_read 3
+and
+.Xr archive_write 3 .
+.Sh COMPATIBILITY
+The bundled-arguments format is supported for compatibility
+with historic implementations.
+It consists of an initial word (with no leading - character) in which
+each character indicates an option.
+Arguments follow as separate words.
+The order of the arguments must match the order
+of the corresponding characters in the bundled command word.
+For example,
+.Dl Nm Cm tbf 32 Pa file.tar
+specifies three flags
+.Cm t ,
+.Cm b ,
+and
+.Cm f .
+The
+.Cm b
+and
+.Cm f
+flags both require arguments,
+so there must be two additional items
+on the command line.
+The
+.Ar 32
+is the argument to the
+.Cm b
+flag, and
+.Ar file.tar
+is the argument to the
+.Cm f
+flag.
+.Pp
+The mode options c, r, t, u, and x and the options
+b, f, l, m, o, v, and w comply with SUSv2.
+.Pp
+For maximum portability, scripts that invoke
+.Nm tar
+should use the bundled-argument format above, should limit
+themselves to the
+.Cm c ,
+.Cm t ,
+and
+.Cm x
+modes, and the
+.Cm b ,
+.Cm f ,
+.Cm m ,
+.Cm v ,
+and
+.Cm w
+options.
+.Pp
+Additional long options are provided to improve compatibility with other
+tar implementations.
+.Sh SECURITY
+Certain security issues are common to many archiving programs, including
+.Nm .
+In particular, carefully-crafted archives can request that
+.Nm
+extract files to locations outside of the target directory.
+This can potentially be used to cause unwitting users to overwrite
+files they did not intend to overwrite.
+If the archive is being extracted by the superuser, any file
+on the system can potentially be overwritten.
+There are three ways this can happen.
+Although
+.Nm
+has mechanisms to protect against each one,
+savvy users should be aware of the implications:
+.Bl -bullet -width indent
+.It
+Archive entries can have absolute pathnames.
+By default,
+.Nm
+removes the leading
+.Pa /
+character from filenames before restoring them to guard against this problem.
+.It
+Archive entries can have pathnames that include
+.Pa ..
+components.
+By default,
+.Nm
+will not extract files containing
+.Pa ..
+components in their pathname.
+.It
+Archive entries can exploit symbolic links to restore
+files to other directories.
+An archive can restore a symbolic link to another directory,
+then use that link to restore a file into that directory.
+To guard against this,
+.Nm
+checks each extracted path for symlinks.
+If the final path element is a symlink, it will be removed
+and replaced with the archive entry.
+If
+.Fl U
+is specified, any intermediate symlink will also be unconditionally removed.
+If neither
+.Fl U
+nor
+.Fl P
+is specified,
+.Nm
+will refuse to extract the entry.
+.El
+To protect yourself, you should be wary of any archives that
+come from untrusted sources.
+You should examine the contents of an archive with
+.Dl Nm Fl tf Pa filename
+before extraction.
+You should use the
+.Fl k
+option to ensure that
+.Nm
+will not overwrite any existing files or the
+.Fl U
+option to remove any pre-existing files.
+You should generally not extract archives while running with super-user
+privileges.
+Note that the
+.Fl P
+option to
+.Nm
+disables the security checks above and allows you to extract
+an archive while preserving any absolute pathnames,
+.Pa ..
+components, or symlinks to other directories.

+.St -p1003.1-2001 .
+The options used by this implementation were developed by surveying a
+number of existing tar implementations as well as the old POSIX specification
+for tar and the current POSIX specification for pax.
+.Pp
+The ustar and pax interchange file formats are defined by
+.St -p1003.1-2001
+for the pax command.
+.Sh HISTORY
+A
+.Nm tar
+command appeared in Seventh Edition Unix, which was released in January, 1979.
+There have been numerous other implementations,
+many of which extended the file format.
+John Gilmore's
+.Nm pdtar
+public-domain implementation (circa November, 1987)
+was quite influential, and formed the basis of GNU tar.
+GNU tar was included as the standard system tar
+in
+.Fx
+beginning with
+.Fx 1.0 .
+.Pp
+This is a complete re-implementation based on the
+.Xr libarchive 3
+library.
+.Sh BUGS
+This program follows
+.St -p1003.1-96
+for the definition of the
+.Fl l
+option.
+Note that GNU tar prior to version 1.15 treated
+.Fl l
+as a synonym for the
+.Fl -one-file-system
+option.
+.Pp
+The
+.Fl C Pa dir
+option may differ from historic implementations.
+.Pp
+All archive output is written in correctly-sized blocks, even
+if the output is being compressed.
+Whether or not the last output block is padded to a full
+block size varies depending on the format and the
+output device.
+For tar and cpio formats, the last block of output is padded
+to a full block size if the output is being
+written to standard output or to a character or block device such as
+a tape drive.
+If the output is being written to a regular file, the last block
+will not be padded.
+Many compressors, including
+.Xr gzip 1
+and
+.Xr bzip2 1 ,
+complain about the null padding when decompressing an archive created by
+.Nm ,
+although they still extract it correctly.
+.Pp
+The compression and decompression is implemented internally, so
+there may be insignificant differences between the compressed output
+generated by
+.Dl Nm Fl czf Pa - file
+and that generated by
+.Dl Nm Fl cf Pa - file | Nm gzip
+.Pp
+The default should be to read and write archives to the standard I/O paths,
+but tradition (and POSIX) dictates otherwise.
+.Pp
+The
+.Cm r
+and
+.Cm u
+modes require that the archive be uncompressed
+and located in a regular file on disk.
+Other archives can be modified using
+.Cm c
+mode with the
+.Pa @archive-file
+extension.
+.Pp
+To archive a file called
+.Pa @foo
+or
+.Pa -foo
+you must specify it as
+.Pa ./@foo
+or
+.Pa ./-foo ,
+respectively.
+.Pp
+In create mode, a leading
+.Pa ./
+is always removed.
+A leading
+.Pa /
+is stripped unless the
+.Fl P
+option is specified.
+.Pp
+There needs to be better support for file selection on both create
+and extract.
+.Pp
+There is not yet any support for multi-volume archives or for archiving
+sparse files.
+.Pp
+Converting between dissimilar archive formats (such as tar and cpio) using the
+.Cm @ Ns Pa -
+convention can cause hard link information to be lost.
+(This is a consequence of the incompatible ways that different archive
+formats store hardlink information.)
+.Pp
+There are alternative long options for many of the short options that
+are deliberately not documented.

+ * This getopt implementation has two key features that common
+ * getopt_long() implementations lack.  Apart from those, it's a
+ * straightforward option parser, considerably simplified by not
+ * needing to support the wealth of exotic getopt_long() features.  It
+ * has, of course, been shamelessly tailored for bsdtar.  (If you're
+ * looking for a generic getopt_long() implementation for your
+ * project, I recommend Gregory Pietsch's public domain getopt_long()
+ * implementation.)  The two additional features are:
+ *
+ * Old-style tar arguments: The original tar implementation treated
+ * the first argument word as a list of single-character option
+ * letters.  All arguments follow as separate words.  For example,
+ *    tar xbf 32 /dev/tape
+ * Here, the "xbf" is three option letters, "32" is the argument for
+ * "b" and "/dev/tape" is the argument for "f".  We support this usage
+ * if the first command-line argument does not begin with '-'.  We
+ * also allow regular short and long options to follow, e.g.,
+ *    tar xbf 32 /dev/tape -P --format=pax
+ *
+ * -W long options: There's an obscure GNU convention (only rarely
+ * supported even there) that allows "-W option=argument" as an
+ * alternative way to support long options.  This was supported in
+ * early bsdtar as a way to access long options on platforms that did
+ * not support getopt_long() and is preserved here for backwards
+ * compatibility.  (Of course, if I'd started with a custom
+ * command-line parser from the beginning, I would have had normal
+ * long option support on every platform so that hack wouldn't have
+ * been necessary.  Oh, well.  Some mistakes you just have to live
+ * with.)
+ *
+ * TODO: We should be able to use this to pull files and intermingled
+ * options (such as -C) from the command line in write mode.  That
+ * will require a little rethinking of the argument handling in
+ * bsdtar.c.
+ *
+ * TODO: If we want to support arbitrary command-line options from -T
+ * input (as GNU tar does), we may need to extend this to handle option
+ * words from sources other than argv/arc.  I'm not really sure if I
+ * like that feature of GNU tar, so it's certainly not a priority.

+ *
+ * Someday, I want to convert the Win32 support to use newer

+ * This is a new directory-walking system that addresses a number
+ * of problems I've had with fts(3).  In particular, it has no
+ * pathname-length limits (other than the size of 'int'), handles
+ * deep logical traversals, uses considerably less memory, and has
+ * an opaque interface (easier to modify in the future).
+ *
+ * Internally, it keeps a single list of "tree_entry" items that
+ * represent filesystem objects that require further attention.
+ * Non-directories are not kept in memory: they are pulled from
+ * readdir(), returned to the client, then freed as soon as possible.
+ * Any directory entry to be traversed gets pushed onto the stack.
+ *
+ * There is surprisingly little information that needs to be kept for
+ * each item on the stack.  Just the name, depth (represented here as the
+ * string length of the parent directory's pathname), and some markers
+ * indicating how to get back to the parent (via chdir("..") for a
+ * regular dir or via fchdir(2) for a symlink).

+ *      package does use a chdir approach for logical traversals
+ *      and can therefore handle pathnames much longer than PATH_MAX.
+ *    * Supports deep physical traversals "out of the box."
