24 @setfilename archive-info
29 An archive (or library) is just another BFD. It has a symbol
30 table, although there's not much a user program will do with it.
32 The big difference between an archive BFD and an ordinary BFD
33 is that the archive doesn't have sections. Instead it has a
34 chain of BFDs that are considered its contents. These BFDs can
35 be manipulated like any other. The BFDs contained in an
36 archive opened for reading will all be opened for reading. You
37 may put either input or output BFDs into an archive opened for
38 output; they will be handled correctly when the archive is closed.
40 Use <<bfd_openr_next_archived_file>> to step through
41 the contents of an archive opened for input. You don't
42 have to read the entire archive if you don't want
43 to! Read it until you find what you want.
45 Archive contents of output BFDs are chained through the
46 <<next>> pointer in a BFD. The first one is findable through
47 the <<archive_head>> slot of the archive. Set it with
48 <<bfd_set_archive_head>> (q.v.). A given BFD may be in only one
49 open output archive at a time.
51 As expected, the BFD archive code is more general than the
52 archive code of any given environment. BFD archives may
53 contain files of different formats (e.g., a.out and coff) and
54 even different architectures. You may even place archives
55 recursively into archives!
57 This can cause unexpected confusion, since some archive
58 formats are more expressive than others. For instance, Intel
59 COFF archives can preserve long filenames; SunOS a.out archives
60 cannot. If you move a file from the first to the second
61 format and back again, the filename may be truncated.
62 Likewise, different a.out environments have different
63 conventions as to how they truncate filenames, whether they
64 preserve directory names in filenames, etc. When
65 interoperating with native tools, be sure your files are
68 Beware: most of these formats do not react well to the
69 presence of spaces in filenames. We do the best we can, but
70 can't always handle this case due to restrictions in the format of
71 archives. Many Unix utilities are braindead in regards to
72 spaces and such in filenames anyway, so this shouldn't be much
75 Archives are supported in BFD in <<archive.c>>.
82 o - all archive elements start on an even boundary, newline padded;
83 o - all arch headers are char *;
84 o - all arch headers are the same size (across architectures).
87 /* Some formats provide a way to cram a long filename into the short
88 (16 chars) space provided by a BSD archive. The trick is: make a
89 special "file" in the front of the archive, sort of like the SYMDEF
90 entry. If the filename is too long to fit, put it in the extended
91 name table, and use its index as the filename. To prevent
92 confusion prepend the index with a space. This means you can't
93 have filenames that start with a space, but then again, many Unix
94 utilities can't handle that anyway.
96 This scheme unfortunately requires that you stand on your head in
97 order to write an archive since you need to put a magic file at the
98 front, and need to touch every entry to do so. C'est la vie.
100 We support two variants of this idea:
101 The SVR4 format (extended name table is named "//"),
102 and an extended pseudo-BSD variant (extended name table is named
103 "ARFILENAMES/"). The origin of the latter format is uncertain.
105 BSD 4.4 uses a third scheme: It writes a long filename
106 directly after the header. This allows 'ar q' to work.
109 /* Summary of archive member names:
111 Symbol table (must be first):
112 "__.SYMDEF " - Symbol table, Berkeley style, produced by ranlib.
113 "/ " - Symbol table, system 5 style.
115 Long name table (must be before regular file members):
116 "// " - Long name table, System 5 R4 style.
117 "ARFILENAMES/ " - Long name table, non-standard extended BSD (not BSD 4.4).
119 Regular file members with short names:
120 "filename.o/ " - Regular file, System 5 style (embedded spaces ok).
121 "filename.o " - Regular file, Berkeley style (no embedded spaces).
123 Regular files with long names (or embedded spaces, for BSD variants):
124 "/18 " - SVR4 style, name at offset 18 in name table.
125 "#1/23 " - Long name (or embedded spaces) 23 characters long,
126 BSD 4.4 style, full name follows header.
127 " 18 " - Long name 18 characters long, extended pseudo-BSD.
