 quorum

    OpenVMS usage word_signed

    The number of participants required to terminate an active
    wait for this barrier. The quorum argument is the address of a
    signed word containing the quorum number. For example, a quorum
    value of 3 indicates that the first two callers of PPL$WAIT_
    AT_BARRIER specifying this barrier-id are blocked until a third
    participant calls PPL$WAIT_AT_BARRIER. At that point, all three
    are released for further processing. If you specify zero for
    quorum, the quorum is set to the number of processes currently in
    the application. The value of quorum must be positive or zero.
