The logical extension of the concept ofpassing a pointer to a functionleads to passing aUnionpointer, i.e., the pointer of amulti-dimensional array, passing the pointer of aself-referential structure, etc., all these have important uses in different application areas such as complex data struct...
On x86 plaftorms, all arguments are widened to 32 bits when they are passed. Return values are also widened to 32 bits and returned in the EAX register, except for 8-byte structures, which are returned in the EDX:EAX register pair. Larger structures are returned in the EAX register as ...
