SECTION
Archives
DESCRIPTION
- Gumby, you promised to write this bit...
+ 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 that are considered its contents. These BFDs can
+ be manipulated 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; they will be handled correctly when the archive is closed.
+
+ Use <<bfd_openr_next_archived_file>> to step through
+ the contents of an archive opened for input. You don't
+ have to read the entire archive if you don't want
+ to! Read it until you find what you want.
+
+ A BFD returned by <<bfd_openr_next_archived_file>> can be
+ closed manually with <<bfd_close>>. If you do not close it,
+ then a second iteration through the members of an archive may
+ return the same BFD. If you close the archive BFD, then all
+ the member BFDs will automatically be closed as well.
+
+ Archive contents of output BFDs are chained through the
+ <<archive_next>> pointer in a BFD. The first one is findable
+ through the <<archive_head>> slot of the archive. Set it with
+ <<bfd_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; SunOS 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 case due to restrictions 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.
Archives are supported in BFD in <<archive.c>>.
- An archive is represented internally just like another BFD,
- with a pointer to a chain of contained BFDs. Archives can be
- created by opening BFDs, linking them together and attaching
- them as children to another BFD and then closing the parent
- BFD.

/* Assumes:
o - all arch headers are the same size (across architectures).

-/* $Id$ */
+/* 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.
+*/
+
+/* 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 spaces) 23 characters long,
+ BSD 4.4 style, full name follows header.
+ " 18 " - Long name 18 characters long, extended pseudo-BSD.
