Declaration

function Seg(

var X

):LongInt;

Description

Seg returns the segment of the address of a variable. This function is only supported for compatibility. In Free Pascal, it returns always 0, since Free Pascal uses a flat 32/64 bit memory model. In such a memory model segments have no meaning.

Errors

None.
