FUNCTION
Compares two Locks. Returns LOCK_SAME if they are on the same object, LOCK_SAME_VOLUME if on different objects on the same volume, and LOCK_DIFFERENT if they are on different volumes. Always compare for equality or non-equality with the results, in case new return values are added.
INPUTS
RESULT
- value
-
LOCK_SAME, LOCK_SAME_VOLUME, or LOCK_DIFFERENT
BUGS
Should do more extensive checks for NULL against a real Lock, checking to see if the real Lock is a Lock on the root of the boot volume.
In V36, it would return LOCK_SAME_VOLUME for different volumes on the same handler. Also, LOCK_SAME_VOLUME was LOCK_SAME_HANDLER (now an obsolete #define, see dos/dos.h).
