The GOT holds the address in the PLT to be executed.
The loader then gets:
- 24(15) = Pointer to the structure describing the object.
- 28(15) = Offset in symbol table
+ 48(15) = Pointer to the structure describing the object.
+ 56(15) = Offset in symbol table
The loader must then find the module where the function is
and insert the address in the GOT.
