/sys$common/syshlp/helplib.hlb System Services, $GETLKIW  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Returns information about the lock database on a system.

    The $GETLKIW service completes synchronously; that is, it returns
    to the caller with the requested information.

    For asynchronous completion, use the Get Lock Information
    ($GETLKI) service; $GETLKI returns to the caller after queuing
    the information request, without waiting for the information to
    be returned.

    In all other respects, $GETLKIW is identical to $GETLKI. For
    all other information about the $GETLKIW service, refer to the
    description of $GETLKI in this manual.

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