12 * An additional locale model to support C++ Standard Library locale
13 model and probably more was implemented by Ulrich Drepper.
15 * Eric Youngdale and Ulrich Drepper implemented versioning of objects on
18 * Miles Bader provided the `argp' function family to support hierachical
19 command line argument parsing, layered on top of getopt.
21 * strtod accepts new hexadecimal floating-point format from ISO C 9X.
23 * printf has two new specifiers %a and %A to print hexadecimal flaoting-point
26 * scanf recognizes the %a and %A format for scanning floating point numbers.
28 * the new header <inttypes.h> from ISO C 9X provides information and
29 interfaces for the available integer types.
31 * the new header <complex.h> contains definitions of the complex math
32 functions from ISO C 9X.
34 * the new header <tgmath.h> defines generic macros to use complex or
35 real valued functions.
37 * Thorsten Kukuk provided an implementation for NIS+, securelevel 0, 1 and 2.
39 * Andreas Jaeger provided a test suite for the math library.
41 * Mark Kettenis implemented the utmpx interface and an utmp daemon.
43 * Ulrich Drepper added character conversion functions.
45 * Optimized string functions have been added.
47 * The localedata addon is now part of glibc.
53 * inet_ntoa is thread-safe
55 * updwtmp is moved from libutil to libc
57 * rewrite of cbrt function
59 * update of timezone data
75 * fix complex problems in Berkeley DB code
81 * fixed lots of header problems (especially Linux/GNU specific)
83 * dynamic loader preserves all registers
85 * Roland McGrath provided support for handling of auxiliary objects in
86 the ELF dynamic loader.
88 * support for parallel builds is improved
92 * GNU extensions are no longer declared by default. To enable them you
93 must define the macro `_GNU_SOURCE' in your program or compile with
96 * The library has changed from using GNU ld symbol aliases to using weak
97 symbols where available. The ELF object file format supports weak
98 symbols; GNU ld also supports weak symbols in the a.out format. (There
99 is also now support for other GNU ld extensions in ELF. Use the
100 `--with-elf' option to configure to indicate you have ELF, and
101 `--with-gnu-ld' if using GNU ld.) This change resulted in the deletion
102 of many files which contained only symbol aliases, reducing the size of
103 the source and the compiled library; many other files were renamed to
104 less cryptic names previously occupied by the symbol alias files.
105 There is a new header file <elf.h> for programs which operate on
106 files in the ELF format.
108 * Converted to Autoconf version 2, so `configure' has more options.
109 Run `configure --help' to see the details.
111 * The library can now be configured to build profiling, highly-optimized
112 (but undebuggable), and/or shared libraries (ELF with GNU ld only). The
113 `--enable-profile', `--enable-omitfp', and `--enable-shared' options to
114 `configure' enable building these extra libraries. The shared library is
115 built by default when using both ELF and GNU ld. When shared libraries
116 are enabled, the new library `-ldl' is available for arbitrary run-time
117 loading of shared objects; its interface is defined in <dlfcn.h>. The
118 new header file <link.h> gives access to the internals of the run-time
119 dynamic linker, `ld.so'. The shell script `ldd' is similar to the
120 application of same name on other systems and it provides information
121 about dynamically linked binaries.
123 * The C library now provides the run-time support code for profiling
124 executables compiled with `-pg'. Programs can control the profiling code
125 through the interface in <sys/gmon.h>. The `gmon.out' files written by
126 the GNU C library can be read only by GNU `gprof' (from GNU binutils);
127 the support for this file format was contributed by David Mosberger-Tang.
129 * The math code has been replaced with a math library based on fdlibm from
130 Sun, and modified by JT Conklin and Ulrich Drepper with i387 support, by
131 Ian Taylor with `float' functions and by Ulrich Drepper with `long double'
132 functions. The math functions now reside in a separate library, so
133 programs using them will need to use `-lm' their linking commands.
135 * John C. Bowman contributed optimized ix87 assembler inline functions.
137 * Ulrich Drepper has contributed support for an `/etc/nsswitch.conf'
138 mechanism similar to that found in Solaris 2. This is now used for the
139 group, passwd, hosts, networks, services, protocols, rpc, ethers,
140 shadow, netgroup, publickey, and alias databases. The `nsswitch.conf'
141 file controls what services are used for each individual database. This
142 works by loading shared libraries with names specified in `nsswitch.conf',
143 so service modules can be changed or added at any time without even
144 relinking any program. Currently there are the file, db, and NIS based
145 NSS services available.
147 * The new functions `strtoq' and `strtouq' parse integer values from
148 strings, like `strtol' and `strtoul', but they return `long long int' and
149 `unsigned long long int' values, respectively (64-bit quantities).
151 * The new functions `strtof' and `strtold' parse floating-point values from
152 strings, like `strtod', but they return `float' and `long double' values,
153 respectively (on some machines `double' and `long double' are the same).
155 * Ulrich Drepper has contributed new implementations of the floating-point
156 printing and reading code used in the `printf' family of functions and
157 `strtod', `strtof', and `strtold'. These new functions are perfectly
158 accurate, and much faster than the old ones.
160 * The implementation of the POSIX locale model was completely rewritten by
161 Ulrich Drepper. This includes the new programs `localedef' and `locale'
162 to compile the POSIX locale definition.
164 * The former dummy implementations of the strcoll and strxfrm function are
165 now replaced by fully functional code contributed by Ulrich Drepper. The
166 collation information comes from the POSIX locale definitions.
168 * The new header <langinfo.h> defines an interface for accessing
169 various locale-dependent data (using the locale chosen with `setlocale').
171 * Ulrich Drepper has contributed a new suite of functions for operation on
172 wide-character and multibyte-character strings, in <wchar.h>;
173 and classification and case conversion of wide characters, in <wctype.h>.
174 These new functions are conforming to the ISO C, Amendement 1 specification.
176 * There is now a second implementation of the standard I/O library available.
177 It comes from GNU libg++ as was written by Per Bothner, heavily modified
178 by Hongjiu Lu and made thread safe by Ulrich Drepper.
180 * You can now use positional parameter specifications in format strings
181 for the `printf' and `scanf' families of functions. For example,
182 `printf ("Number %2$d, Mr %1$s\n", "Jones", 6);'' prints
183 ``Number 6, Mr Jones''. This is mainly useful when providing different
184 format strings for different languages, whose grammars may dictate
185 different orderings of the values being printed. To support this
186 feature, the interface for `register_printf_handler' has changed; see
187 the header file <printf.h> for details.
189 * The `printf' and `scanf' families of functions now understand a new
190 formatting flag for numeric conversions: the ' flag (e.g. %'d or %'f) says
191 to group numbers as indicated by the locale; for `scanf' and friends, this
192 says to accept as valid only a number with all the proper grouping
193 separators in the right places. In the default "C" locale, numbers are
194 not grouped; but locales for specific countries will define the usual
195 conventions (i.e. separate thousands with `,' in the US locale).
197 * The pgrp functions have been regularized, slightly incompatibly but much
198 less confusingly. The core functions are now `getpgid' and `setpgid',
199 which take arguments for the PID to operate on; the POSIX.1 `getpgrp' (no
200 argument) and BSD `setpgrp' (identical to `setpgid') functions are
201 provided for compatibility. There is no longer an incompatible `getpgrp'
202 with an argument declared under _BSD_SOURCE; no BSD code uses it.
204 * The new header file <fts.h> and suite of functions simplify programs that
205 operate on directory trees. This code comes from 4.4 BSD.
207 * The resolver code has been updated from the BIND 4.9.5-P1 release.
208 Parts of the code were heavily modified by Ulrich Drepper to fit in the
209 NSS scheme used in glibc.
211 * The new function `malloc_find_object_address' finds the starting address
212 of a malloc'd block, given any address within the block;
213 `malloc_object_allocated_size' returns the size of an allocated block;
214 and `malloc_walk' lets you walk through all allocated blocks. These can
215 be useful for debugging; see <malloc.h> for the interfaces.
217 * There is a new malloc debugging hook `__memalign_hook'.
219 * There are new typedefs `ushort' for `unsigned short int' and `uint' for
220 `unsigned int' in <sys/types.h>. These are for compatibility only and
221 their use is discouraged.
223 * The `-lmcheck' library to enable standard malloc debugging hooks is now
224 done differently, so that it works even without GNU ld.
226 * New function `euidaccess' checks allowed access to a file like `access',
227 but using the effective IDs instead of the real IDs.
229 * The time zone data files have been updated for the latest and greatest
230 local time conventions of the countries of the world.
232 * The new function `dirfd' extracts the file descriptor used by a DIR stream;
235 * The new functions `ecvt', `fcvt', and `gcvt' provide an obsolete interface
236 for formatting floating-point numbers. They are provided only for
237 compatibility; new programs should use `sprintf' instead. There are
238 also equivalent function for the `long double' floating-point type and
239 all functions also exist in a reentrant form.
241 * The new auxiliary library `-lutil' from 4.4 BSD contains various
242 functions for maintaining the login-record files (primarily of use to
243 system programs such as `login'), and convenient functions for
244 allocating and initializing a pseudo-terminal (pty) device.
246 * Ulrich Drepper has contributed new support for System V style
247 shared memory and IPC on systems that support it.
249 * Ulrich Drepper has contributed several miscellaneous new functions found
250 in System V: The `hsearch' family of functions provide an effective
251 implementation of hash tables; `a64l' and `l64a' provide a very simple
252 binary to ASCII mapping; `drand48' and friends provide a 48-bit random
255 * Ulrich Drepper has contributed new reentrant counterparts for the
256 `random' and `hsearch' families of functions; `random_r', `hsearch_r', etc.
258 * Ulrich Drepper has contributed new, highly-optimized versions of several
259 string functions for the i486/Pentium family of processors.
261 * Ulrich Drepper has updated the Linux-specific code, based largely
262 on work done in Hongjiu Lu's version of GNU libc for Linux.
263 The GNU library now supports Linux versions 2.0.10 and later,
264 using the ELF object file format (i[3456]86-*-linux).
266 * Andreas Schwab has ported the C library to Linux/m68k (m68k-*-linux).
268 * David Mosberger-Tang and Richard Henderson have ported the C library
269 to Linux/Alpha (alpha-*-linux). Richard Henderson contributed the
270 dynamic linking support for ELF/Alpha.
272 * Richard Henderson contributed several Alpha optimized assembler function
273 for arithmetic and string handling.
275 * Ulrich Drepper has contributed a new set of message catalog functions to
276 support multiple languages using the <libintl.h> interface, for use with
277 his new package GNU gettext. Translation volunteers have contributed
278 catalogs of the library's messages in Spanish, German, and Korean.
280 * For compatibility with XPG4, Ulrich Drepper has contributed the `gencat'
281 program and the `catgets' function for reading the catalog files it
282 creates. (The <libintl.h> interface is preferred; we include the
283 <nl_types.h> interface using `catgets' only for source compatibility with
284 programs already written to use it.)
286 * New header file <values.h> gives SVID-compatible names for <limits.h>
289 * Various new macros, declarations, and small header files for compatibility
292 * New function `group_member' is a convenient way to check if a process has
293 a given effective group ID.
295 * When using GCC 2.7 and later, the socket functions are now declared in a
296 special way so that passing an argument of type `struct sockaddr_in *',
297 `struct sockaddr_ns *', or `struct sockaddr_un *' instead of the generic
298 `struct sockaddr *' type, does not generate a type-clash warning.
300 * New function `error' declared in header file <error.h> is a convenient
301 function for printing error messages and optionally exiting; this is the
302 canonical function used in GNU programs. The new functions `err', `warn',
303 and friends in header file <err.h> are the canonical 4.4 BSD interface for
304 doing the same thing.
306 * The <glob.h> interface has several new flags from 4.4 BSD that extend the
307 POSIX.2 `glob' function to do ~ and {...} expansion.
309 * New function `unsetenv' complements `setenv' for compatibility with 4.4 BSD.
310 `clearenv' which is used in POSIX.9 is also available.
312 * New function `getsid' returns session ID number on systems that support it.
314 * We have incorporated the 4.4 BSD `db' library (version 1.85). New header
315 files <db.h> and <mpool.h> provide a rich set of functions for several
316 types of simple databases stored in memory and in files, and <ndbm.h> is
317 an old `ndbm'-compatible interface using the `db' functions. Link with
318 `-ldb' to get these functions.
320 * New macro `strdupa' copies a string like `strdup', but uses local stack
321 space from `alloca' instead of dynamic heap space from `malloc'.
323 * New function `strnlen' is like `strlen' but searches only a given maximum
324 number of characters for the null terminator. `stpncpy', `strndup' and
325 `strndupa' are similar variants for the `stpcpy', `strdup' and `strdupa'
328 * New function `statfs' in header <sys/statfs.h>.
330 * The new <argz.h> and <envz.h> interfaces contributed by Miles Bader
331 provide convenient functions for operating on blocks of null-terminated
334 * A new suite of functions in <utmp.h> handle all the details of reading
335 and writing the utmp file.
337 * An implementation of the NIS/YP(tm) based NSS service was contributed by
340 * Paul Eggert and Ulrich Drepper modified the `strftime' function to be
341 completely POSIX compliant and also implemented the extended functionality
342 to handle alternate digit representation and alternate era date formats.
344 * Ulrich Drepper provided an implementation of the `strptime' function
345 defined in XPG4.2 which transforms a string into a `struct tm' value.
347 * Paul Eggert provided the tzselect shell script as part of the timezone
348 code. The shell script makes it easy to select the correct timezone
351 * The implementation of the malloc family of functions is completely replaced
352 by a new implementation by Doug Lea with many improvements by Wolfram Gloger.
353 The implementation uses the mmap function (if available) and it is
354 optimized for the use in multi threaded programs.
356 * Ulrich Drepper contributed a MD5 "encryption" for the crypt family of
357 functions. This new functionality is usable by specifying a special
358 salt string and it is compatible with implementation on *BSD systems.
360 * Lots of functions from the XPG4.2 standard were added by Ulrich Drepper:
361 `getsubopt' to handle second level command line options, `bsd_signal'
362 to access BSD style `signal' functionality, the obsolete `regexp' style
365 * the `lchown' function is available on system which support this
368 * The implementation of the shadow password handling function was contributed
371 * David Mosberger-Tang changed the SunRPC implementation to be 64bit safe.
373 * POSIX.1g support was added. The <sys/select.h> header is available,
374 `isfdtype' and `pselect' are implemented. Craig Metz contributed an
375 implementation of `getaddrinfo'.
379 * For cross-compilation you should now set `BUILD_CC' instead of `HOST_CC'.
381 * New header file <fstab.h> and new functions `getfsspec', `getfsent' and
382 friends, for parsing /etc/fstab. This code comes from 4.4 BSD.
384 * The new function `daemon' from 4.4 BSD is useful for server programs that
385 want to put themselves in the background.
387 * Joel Sherrill has contributed support for several standalone boards that
388 run without an operating system.
390 * `printf', `scanf' and friends now accept a `q' type modifier for long
391 long int as well as `ll'. Formats using these might be `%qu' or `%lld'.
393 * All of the code taken from BSD (notably most of the math and networking
394 routines) has been updated from the BSD 4.4-Lite release.
396 * The resolver code has been updated from the BIND-4.9.3-BETA9 release.
398 * The new functions `getdomainname' and `setdomainname' fetch or change the
399 YP/NIS domain name. These are system calls which exist on systems which
402 * The time zone data files have been updated for the latest international
405 * The SunRPC programs `portmap' and `rpcinfo' are now installed in
406 $(sbindir) (usually /usr/local/sbin) instead of $(bindir).
410 * The C library now includes support for Sun RPC, from Sun's free
411 RPCSRC-4.0 distribution. The `portmap', `rpcinfo', and `rpcgen' programs
412 are included. (There is still no support for YP.)
414 * Tom Quinn has contributed a port of the C library to SGI machines running
415 Irix 4 (mips-sgi-irix4).
417 * The new `lockf' function is a simplified interface to the locking
418 facilities of `fcntl', included for compatibility.
420 * New time functions `timegm', `timelocal', and `dysize' for compatibility.
422 * New header file <sys/timeb.h> and new function `ftime' for compatibility.
424 * New header files <poll.h> and <sys/poll.h> and new function `poll' for
427 * The error message printed by `assert' for a failed assertion now includes
428 the name of the program (if using GNU ld) and the name of the calling
429 function (with versions of GCC that support this).
431 * The `psignal' function is now declared in <signal.h>, not <stdio.h>.
433 * The library now includes the <sys/mman.h> header file and memory
434 management functions `mmap', `munmap', `mprotect', `msync', and
435 `madvise', on systems that support those facilities.
437 * The interface for `mcheck' has changed slightly: the function called to
438 abort the program when an allocation inconsistency is detected now takes
439 an argument that indicates the type of failure. The new function
440 `mprobe' lets you request a consistency check for a particular block at
441 any time (checks are normally done only when you call `free' or `realloc'
444 * It is now possible to easily cross-compile the C library, building on one
445 system a library to run on another machine and/or operating system. All
446 you need to do is set the variable `HOST_CC' in `configparms' to the
447 native compiler for programs to run on the machine you are building on (a
448 few generator programs are used on Unix systems); set `CC' to the
451 * The new function `fexecve' (only implemented on the GNU system) executes
452 a program file given a file descriptor already open on the file.
456 * Brendan Kehoe has contributed most of a port to the DEC Alpha
457 running OSF/1 (alpha-dec-osf1). He says it is 75% complete.
459 * You can set the variable `libprefix' in `configparms' to specify a prefix
460 to be prepended to installed library files; this makes it easy to install
461 the GNU C library to be linked as `-lgnuc' or whatever.
463 * The new `stpncpy' is a cross between `stpcpy' and `strncpy': It
464 copies a limited number of characters from a string, and returns the
465 address of the last character written.
467 * You no longer need to check for whether the installed `stddef.h' is
468 compatible with the GNU C library. configure now checks for you.
470 * You can now define a per-stream `fileno' function to convert the
471 stream's cookie into an integral file descriptor.
473 * ``malloc (0)'' no longer returns a null pointer. Instead, it
474 allocates zero bytes of storage, and returns a unique pointer which
475 you can pass to `realloc' or `free'. The behavior is undefined if
476 you dereference this pointer.
478 * The C library now runs on Sony NEWS m68k machines running either
479 NewsOS 3 or NewsOS 4.
481 * The new `syscall' function is a system-dependent primitive function
482 for invoking system calls. It has the canonical behavior on Unix
483 systems, including unreliable return values for some calls (such as
484 `pipe', `fork' and `getppid').
486 * The error code `EWOULDBLOCK' is now obsolete; it is always defined
487 to `EAGAIN', which is the preferred name. On systems whose kernels
488 use two distinct codes, the C library now translates EWOULDBLOCK to
489 EAGAIN in every system call function.
493 * The GNU C Library Reference Manual is now distributed with the library.
494 `make dvi' will produce a DVI file of the printed manual.
495 `make info' will produce Info files that you can read on line using C-h i
496 in Emacs or the `info' program.
497 Please send comments on the manual to bug-glibc-manual@prep.ai.mit.edu.
499 * The library now supports SVR4 on i386s (i386-unknown-sysv4).
501 * Brendan Kehoe has contributed a port to Sun SPARCs running Solaris 2.
503 * Jason Merrill has contributed a port to the Sequent Symmetry running
504 Dynix version 3 (i386-sequent-dynix).
506 * The library has been ported to i386s running SCO 3.2.4 (also known as SCO
507 ODT 2.0; i386-unknown-sco3.2.4) or SCO 3.2 (i386-unknown-sco3.2).
509 * New function `memory_warnings' lets you arrange to get warnings when
510 malloc is running out of memory to allocate, like Emacs gives you.
512 * The C library now contains the relocating allocator used in Emacs 19 for
513 its editing buffers. This allocator (ralloc) minimizes allocation
514 overhead and fragmentation by moving allocated regions around whenever it
515 needs to. You always refer to a ralloc'd region with a "handle" (a
516 pointer to a pointer--an object of type `void **').
518 * There is a new `printf' format: `%m' gives you the string corresponding
519 to the error code in `errno'.
521 * In `scanf' formats, you can now use `%as' or `%a[' to do the normal `%s'
522 or `%[' conversion, but instead of filling in a fixed-sized buffer you
523 pass, the `a' modifier says to fill in a `char **' you pass with a
526 * The `fnmatch' function supports the new flag bits `FNM_LEADING_DIR' and
527 `FNM_CASEFOLD'. `FNM_LEADING_DIR' lets a pattern like `foo*' match a
528 name like `foo/bar'. `FNM_CASEFOLD' says to ignore case in matching.
530 * `mkstemp' is a traditional Unix function to atomically create and open a
531 uniquely-named temporary file.
535 * The standard location for the file that says what the local timezone is
536 has changed again. It is now `/usr/local/etc/localtime' (or more
537 precisely, `${prefix}/etc/localtime') rather than `/etc/localtime'.
539 * The distribution no longer contains any files with names longer than 14
542 * `struct ttyent' has two new flag bits: TTY_TRUSTED and TTY_CONSOLE.
543 These are set by the new `trusted' and `console' keywords in `/etc/ttys'.
545 * New functions `ttyslot' and `syslog' from 4.4 BSD.
549 * The configuration process has changed quite a bit. The `configure'
550 script is now used just like the configuration scripts for other GNU
551 packages. The `sysdeps' directory hierarchy is much rearranged.
552 The file `INSTALL' explains the new scheme in detail.
554 * The header files no longer need to be processed into ANSI C and
555 traditional C versions. There is just one set of files to install, and
556 it will work with ANSI or old C compilers (including `gcc -traditional').
558 * Brendan Kehoe and Ian Lance Taylor have ported the library to the
559 MIPS DECStation running Ultrix 4.
561 * The Sun 4 startup code (crt0) can now properly load SunOS 4 shared libraries.
562 Tom Quinn contributed the initial code. The GNU C library can NOT yet be
563 made itself into a shared library.
565 * Yet further improved support for the i386, running 4.3 BSD-like systems
566 (such as Mach 3 with the Unix single-server), or System V.
568 * New function `strncasecmp' to do case-insensitive string comparison
571 * New function `strsep' is a reentrant alternative to `strtok'.
573 * New functions `scandir' and `alphasort' for searching directories.
575 * New function `setenv' is a better interface to `putenv'.
577 * Ian Lance Taylor has contributed an implementation of the SVID `ftw'
578 function for traversing a directory tree.
580 * The GNU obstack package is now also part of the C library.
581 The new function `open_obstack_stream' creates a stdio stream that
582 writes onto an obstack; `obstack_printf' and `obstack_vprintf' do
583 formatted output directly to an obstack.
585 * Miscellaneous new functions: reboot, nice, sigaltstack (4.4 BSD only),
586 cfmakeraw, getusershell, getpass, swab, getttyent, seteuid, setegid.
588 * `FNM_FILE_NAME' is another name for `FNM_PATHNAME', used with `fnmatch'.
590 * The new functions `strfry' and `memfrob' do mysterious and wonderful
591 things to your strings.
593 * There are some new test programs: test-fseek, testmb, and testrand.
595 * Some work has been done to begin porting the library to 4.4 BSD and Linux.
596 These ports are not finished, but are a good starting place for really
597 supporting those systems.
599 * `/etc/localtime' is now the standard location for the file that says what
600 the local timezone is, rather than `/usr/local/lib/zoneinfo/localtime'.
601 This follows the general principle that `/etc' is the place for all local
604 * The C library header files now use `extern "C"' when used by the C++
605 compiler, so the C library should now work with C++ code.
607 * The header file <bstring.h> is gone. <string.h> now declares bcopy,
608 bcmp, bzero, and ffs.
610 * Mike Haertel (of GNU e?grep and malloc fame) has written a new sorting
611 function which uses the `merge sort' algorithm, and is said to be
612 significantly faster than the old GNU `qsort' function. Merge sort is
613 now the standard `qsort' function. The new algorithm can require a lot
614 of temporary storage; so, the old sorting function is called when the
615 required storage is not available.
617 * The C library now includes Michael Glad's Ultra Fast Crypt, which
618 provides the Unix `crypt' function, plus some other entry points.
619 Because of the United States export restriction on DES implementations,
620 we are distributing this code separately from the rest of the C library.
621 There is an extra distribution tar file just for crypt; it is called
622 `glibc-VERSION-crypt.tar.Z', e.g. `glibc-1.04-crypt.tar.Z'. You can just
623 unpack the crypt distribution along with the rest of the C library and
624 build; you can also build the library without getting crypt. Users
625 outside the USA can get the crypt distribution via anonymous FTP from
626 ftp.uni-c.dk [129.142.6.74], or another archive site outside the U.S.
628 * The code and header files taken from 4.4 BSD have been updated with the
629 latest files released from Berkeley.
