...Global Offset Table... It's one of those things that most people know but find it hard to describe, so there's little documentation lying about the Web. This article ( http://www.linuxjournal.com/article.php?sid=1052 ) makes some mention of it and describes it as well as I could hope: "The library image contains the actual executable functions used by binary programs. The image also contains two tables of particular note: the jump table and the global offset table (GOT). The jump table contains eight-byte entries which redirect a call to a shared function from the jump table to the real function. The jump table exists to provide a method for creating compatible replacement libraries. Since each function has an entry of fixed size in the jump table, the jump table can provide an entry point for these functions at a location that remains constant between revisions of a library. This allows previously linked executables to continue to function without recompilation. The global offset table functions for global variables as the jump table does for library functions." Hope that helps. -- { IRL(Jeremy_Stanley); PGP(9E8DFF2E4F5995F8FEADDC5829ABF7441FB84657); SMTP([EMAIL PROTECTED]); IRC([EMAIL PROTECTED]); ICQ(114362511); AIM(dreadazathoth); YAHOO(crawlingchaoslabs); FINGER([EMAIL PROTECTED]); MUD([EMAIL PROTECTED]:2325); WWW(http://fungi.yuggoth.org/); }
