For a pointer to an ordinary DJGPP variable, a call to _my_ds() will
get you the selector, and the offset is just the address itself.
However, AFAIK, almost no low-level programming requires to know the
selector of a pointer, so please explain more about what are you
trying to accomplish, because you might go in the wrong direction.
