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

Using the following chars caused a compiler warning on HIUX (so I replaced
|
||
them with octal escapes), and isn't useful without an understanding of what
|
||
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
|
||

starts with a 12 character decimal string which is the number of

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. */
