Arguments

 

barrier-id

   OpenVMS usage identifier
   type          longword (unsigned)
   access        read only
   mechanism     by reference
   Identifier of the barrier. The barrier-id argument is the address
   of the barrier identifier.

   Barrier-id is returned by PPL$CREATE_BARRIER.
 

quorum

   OpenVMS usage word_signed
   type          word (signed)
   access        read only
   mechanism     by reference
   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.
