FIXME: Can someone provide a transliteration of this name into ASCII?

|
||
character set it is.

/* XCOFF archive support. The original version of this code was by
|
||
Damon A. Permezel. It was enhanced to permit cross support, and
|
||
writing archive files, by Ian Lance Taylor, Cygnus Support.
|
||
|
||
XCOFF uses its own archive format. Everything is hooked together
|
||
with file offset links, so it is possible to rapidly update an
|
||
archive in place. Of course, we don't do that. An XCOFF archive
|
||
has a real file header, not just an ARMAG string. The structure of
|
||
the file header and of each archive header appear below.
|
||
|
||
An XCOFF archive also has a member table, which is a list of
|
||
elements in the archive (you can get that by looking through the
|
||
linked list, but you have to read a lot more of the file). The
|
||
member table has a normal archive header with an empty name. It is
|
||
normally (and perhaps must be) the second to last entry in the
|
||
archive. The member table data is almost printable ASCII. It
|
||
starts with a 12 character decimal string which is the number of
|
||
entries in the table. For each entry it has a 12 character decimal
|
||
string which is the offset in the archive of that member. These
|
||
entries are followed by a series of null terminated strings which
|
||
are the member names for each entry.
|
||
|
||
Finally, an XCOFF archive has a global symbol table, which is what
|
||
we call the armap. The global symbol table has a normal archive
|
||
header with an empty name. It is normally (and perhaps must be)
|
||
the last entry in the archive. The contents start with a four byte
|
||
binary number which is the number of entries. This is followed by
|
||
a that many four byte binary numbers; each is the file offset of an
|
||
entry in the archive. These numbers are followed by a series of
|
||
null terminated strings, which are symbol names.
|
||
|
||
AIX 4.3 introduced a new archive format which can handle larger
|
||
files and also 32- and 64-bit objects in the same archive. The
|
||
things said above remain true except that there is now more than
|
||
one global symbol table. The one is used to index 32-bit objects,
|
||
the other for 64-bit objects.
|
||
|
||
The new archives (recognizable by the new ARMAG string) has larger
|
||
field lengths so that we cannot really share any code. Also we have
|
||
to take care that we are not generating the new form of archives
|
||
on AIX 4.2 or earlier systems. */
