Procedure Linkage Table

The PLT is a kind of table holding the actual call code; by referencing its contents, _dl_runtime_resulve runs and the actual system library call is made.
(It serves to connect to the GOT; in the actual binary, too, the PLT is called instead of the address of the function/library you want to use.)
