		void *	location2
	)

Returns:

A negative value if the first pointer is in a lower memory address than the second, a positive value if the first pointer is in a higher memory address than the second, zero if they point to the same location.

int pointer_equal	(	void *	location1,
		void *	location2

Parameters:

	location1	The first pointer.
	location2	The second pointer.

Returns:

Non-zero if the pointers are equal, zero if they are not equal.
