22 @setfilename archive-info
27 An archive (or library) is just another BFD. It has a symbol
28 table, although there's not much a user program will do with it.
30 The big difference between an archive BFD and an ordinary BFD
31 is that the archive doesn't have sections. Instead it has a
32 chain of BFDs that are considered its contents. These BFDs can
33 be manipulated like any other. The BFDs contained in an
34 archive opened for reading will all be opened for reading. You
35 may put either input or output BFDs into an archive opened for
36 output; they will be handled correctly when the archive is closed.
38 Use <<bfd_openr_next_archived_file>> to step through
39 the contents of an archive opened for input. You don't
40 have to read the entire archive if you don't want
41 to! Read it until you find what you want.
43 Archive contents of output BFDs are chained through the
44 <<next>> pointer in a BFD. The first one is findable through
45 the <<archive_head>> slot of the archive. Set it with
46 <<bfd_set_archive_head>> (q.v.). A given BFD may be in only one
47 open output archive at a time.
49 As expected, the BFD archive code is more general than the
50 archive code of any given environment. BFD archives may
51 contain files of different formats (e.g., a.out and coff) and
52 even different architectures. You may even place archives
53 recursively into archives!
55 This can cause unexpected confusion, since some archive
56 formats are more expressive than others. For instance, Intel
57 COFF archives can preserve long filenames; SunOS a.out archives
58 cannot. If you move a file from the first to the second
59 format and back again, the filename may be truncated.
60 Likewise, different a.out environments have different
61 conventions as to how they truncate filenames, whether they
62 preserve directory names in filenames, etc. When
63 interoperating with native tools, be sure your files are
66 Beware: most of these formats do not react well to the
67 presence of spaces in filenames. We do the best we can, but
68 can't always handle this case due to restrictions in the format of
69 archives. Many Unix utilities are braindead in regards to
70 spaces and such in filenames anyway, so this shouldn't be much
73 Archives are supported in BFD in <<archive.c>>.
78 o - all archive elements start on an even boundary, newline padded;
79 o - all arch headers are char *;
80 o - all arch headers are the same size (across architectures).
83 /* Some formats provide a way to cram a long filename into the short
84 (16 chars) space provided by a BSD archive. The trick is: make a
85 special "file" in the front of the archive, sort of like the SYMDEF
86 entry. If the filename is too long to fit, put it in the extended
87 name table, and use its index as the filename. To prevent
88 confusion prepend the index with a space. This means you can't
89 have filenames that start with a space, but then again, many Unix
90 utilities can't handle that anyway.
92 This scheme unfortunately requires that you stand on your head in
93 order to write an archive since you need to put a magic file at the
94 front, and need to touch every entry to do so. C'est la vie.
96 We support two variants of this idea:
97 The SVR4 format (extended name table is named "//"),
98 and an extended pseudo-BSD variant (extended name table is named
99 "ARFILENAMES/"). The origin of the latter format is uncertain.
101 BSD 4.4 uses a third scheme: It writes a long filename
102 directly after the header. This allows 'ar q' to work.
103 We currently can read BSD 4.4 archives, but not write them.
106 /* Summary of archive member names:
108 Symbol table (must be first):
109 "__.SYMDEF " - Symbol table, Berkeley style, produced by ranlib.
110 "/ " - Symbol table, system 5 style.
112 Long name table (must be before regular file members):
113 "// " - Long name table, System 5 R4 style.
114 "ARFILENAMES/ " - Long name table, non-standard extended BSD (not BSD 4.4).
116 Regular file members with short names:
117 "filename.o/ " - Regular file, System 5 style (embedded spaces ok).
118 "filename.o " - Regular file, Berkeley style (no embedded spaces).
120 Regular files with long names (or embedded spaces, for BSD variants):
121 "/18 " - SVR4 style, name at offset 18 in name table.
122 "#1/23 " - Long name (or embedded paces) 23 characters long,
123 BSD 4.4 style, full name follows header.
124 Implemented for reading, not writing.
125 " 18 " - Long name 18 characters long, extended pseudo-BSD.
