Returns information about the lock database on a system.

    The $GETLKI service completes asynchronously; for synchronous
    completion, use the Get Lock Information and Wait ($GETLKIW)
    service.

    The $GETLKI, $GETLKIW, $ENQ, $ENQW, and $DEQ services together
    provide the user interface to the Lock Management facility.
