To make the code position independent and to permit the executable to override symbols defined in the shared library, all global variables are accessed via a table of addresses (the Global Offset Table, or GOT) and all functions are called via a table of branches (the Procedure Linkage Table, or PLT). The dynamic linker initializes the GOT and PLT at runtime. The precise details depend on the platform. Ian
