- SECTION
- Archives
-
- DESCRIPTION
- Archives are supported in BFD in <<archive.c>>.
-
- An archive (or library) is just another BFD. It has a symbol
- table, although there's not much a user program will do with it.
-
- The big difference between an archive BFD and an ordinary BFD
- is that the archive doesn't have sections. Instead it has a
- chain of BFDs considered its contents. These BFDs can be
- manipulated just like any other. The BFDs contained in an
- archive opened for reading will all be opened for reading; you
- may put either input or output BFDs into an archive opened for
- output; it will be handled correctly when the archive is closed.
-
- Use <<bfd_openr_next_archived_file>> to step through all
- the contents of an archive opened for input. It's not
- required that you read the entire archive if you don't want
- to! Read it until you find what you want.
-
- Archive contents of output BFDs are chained through the
- <<next>> pointer in a BFD. The first one is findable through
- the <<archive_head>> slot of the archive. Set it with
- <<set_archive_head>> (q.v.). A given BFD may be in only one
- open output archive at a time.
-
- As expected, the BFD archive code is more general than the
- archive code of any given environment. BFD archives may
- contain files of different formats (e.g., a.out and coff) and
- even different architectures. You may even place archives
- recursively into archives!
-
- This can cause unexpected confusion, since some archive
- formats are more expressive than others. For instance, Intel
- COFF archives can preserve long filenames; Sun a.out archives
- cannot. If you move a file from the first to the second
- format and back again, the filename may be truncated.
- Likewise, different a.out environments have different
- conventions as to how they truncate filenames, whether they
- preserve directory names in filenames, etc. When
- interoperating with native tools, be sure your files are
- homogeneous.
-
- Beware: most of these formats do not react well to the
- presence of spaces in filenames. We do the best we can, but
- can't always handle this due to restrctions in the format of
- archives. Many unix utilities are braindead in regards to
- spaces and such in filenames anyway, so this shouldn't be much
- of a restriction.
- */
-
- /* Assumes:
- o - all archive elements start on an even boundary, newline padded;
- o - all arch headers are char *;
- o - all arch headers are the same size (across architectures).
- */
-
- /* Some formats provide a way to cram a long filename into the short
- (16 chars) space provided by a bsd archive. The trick is: make a
- special "file" in the front of the archive, sort of like the SYMDEF
- entry. If the filename is too long to fit, put it in the extended
- name table, and use its index as the filename. To prevent
- confusion prepend the index with a space. This means you can't
- have filenames that start with a space, but then again, many unix
- utilities can't handle that anyway.
-
- This scheme unfortunately requires that you stand on your head in
- order to write an archive since you need to put a magic file at the
- front, and need to touch every entry to do so. C'est la vie.
-
- We support two variants of this idea:
- The SVR4 format (extended name table is named "//"),
- and an extended pseudo-BSD variant (extended name table is named
- "ARFILENAMES/"). The origin of the latter format is uncertain.
-
- BSD 4.4 uses a third scheme: It writes a long filename
- directly after the header. This allows 'ar q' to work.
- We current can read BSD 4.4 archives, but not write them.
- */
-
- /* Summary of archive member names:
-
- Symbol table (must be first):
- "__.SYMDEF " - Symbol table, Berkeley style, produced by ranlib.
- "/ " - Symbol table, system 5 style.
-
- Long name table (must be before regular file members):
- "// " - Long name table, System 5 R4 style.
- "ARFILENAMES/ " - Long name table, non-standard extended BSD (not BSD 4.4).
-
- Regular file members with short names:
- "filename.o/ " - Regular file, System 5 style (embedded spaces ok).
- "filename.o " - Regular file, Berkeley style (no embedded spaces).
-
- Regular files with long names (or embedded spaces, for BSD variants):
- "/18 " - SVR4 style, name at offset 18 in name table.
- "#1/23 " - Long name (or embedded paces) 23 characters long,
- BSD 4.4 style, full name follows header.
- Implemented for reading, not writing.
- " 18 " - Long name 18 characters long, extended pseudo-BSD.
