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 A BFD returned by <<bfd_openr_next_archived_file>> can be
44 closed manually with <<bfd_close>>. If you do not close it,
45 then a second iteration through the members of an archive may
46 return the same BFD. If you close the archive BFD, then all
47 the member BFDs will automatically be closed as well.
49 Archive contents of output BFDs are chained through the
50 <<archive_next>> pointer in a BFD. The first one is findable
51 through the <<archive_head>> slot of the archive. Set it with
52 <<bfd_set_archive_head>> (q.v.). A given BFD may be in only
53 one open output archive at a time.
55 As expected, the BFD archive code is more general than the
56 archive code of any given environment. BFD archives may
57 contain files of different formats (e.g., a.out and coff) and
58 even different architectures. You may even place archives
59 recursively into archives!
61 This can cause unexpected confusion, since some archive
62 formats are more expressive than others. For instance, Intel
63 COFF archives can preserve long filenames; SunOS a.out archives
64 cannot. If you move a file from the first to the second
65 format and back again, the filename may be truncated.
66 Likewise, different a.out environments have different
67 conventions as to how they truncate filenames, whether they
68 preserve directory names in filenames, etc. When
69 interoperating with native tools, be sure your files are
72 Beware: most of these formats do not react well to the
73 presence of spaces in filenames. We do the best we can, but
74 can't always handle this case due to restrictions in the format of
75 archives. Many Unix utilities are braindead in regards to
76 spaces and such in filenames anyway, so this shouldn't be much
79 Archives are supported in BFD in <<archive.c>>.
86 o - all archive elements start on an even boundary, newline padded;
87 o - all arch headers are char *;
88 o - all arch headers are the same size (across architectures).
91 /* Some formats provide a way to cram a long filename into the short
92 (16 chars) space provided by a BSD archive. The trick is: make a
93 special "file" in the front of the archive, sort of like the SYMDEF
94 entry. If the filename is too long to fit, put it in the extended
95 name table, and use its index as the filename. To prevent
96 confusion prepend the index with a space. This means you can't
97 have filenames that start with a space, but then again, many Unix
98 utilities can't handle that anyway.
100 This scheme unfortunately requires that you stand on your head in
101 order to write an archive since you need to put a magic file at the
102 front, and need to touch every entry to do so. C'est la vie.
104 We support two variants of this idea:
105 The SVR4 format (extended name table is named "//"),
106 and an extended pseudo-BSD variant (extended name table is named
107 "ARFILENAMES/"). The origin of the latter format is uncertain.
109 BSD 4.4 uses a third scheme: It writes a long filename
110 directly after the header. This allows 'ar q' to work.
113 /* Summary of archive member names:
115 Symbol table (must be first):
116 "__.SYMDEF " - Symbol table, Berkeley style, produced by ranlib.
117 "/ " - Symbol table, system 5 style.
119 Long name table (must be before regular file members):
120 "// " - Long name table, System 5 R4 style.
121 "ARFILENAMES/ " - Long name table, non-standard extended BSD (not BSD 4.4).
123 Regular file members with short names:
124 "filename.o/ " - Regular file, System 5 style (embedded spaces ok).
125 "filename.o " - Regular file, Berkeley style (no embedded spaces).
127 Regular files with long names (or embedded spaces, for BSD variants):
128 "/18 " - SVR4 style, name at offset 18 in name table.
129 "#1/23 " - Long name (or embedded spaces) 23 characters long,
130 BSD 4.4 style, full name follows header.
131 " 18 " - Long name 18 characters long, extended pseudo-BSD.
