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.
