The + monitor object referenced must be one for which the calling thread + currently holds the lock. + + +Returns +~~~~~~~ + +The function returns one of the following values: + +- If successful, ``PR_SUCCESS``. +- If unsuccessful, ``PR_FAILURE``. + + +Description +----------- + +Notification of a monitor signals the change of state of some monitored +data. The changing of that data and the notification must all be +performed while in the monitor. When the notification occurs, the +runtime promotes a thread that is waiting on the monitor to a ready +state. If more than one thread is waiting, the selection of which thread +gets promoted cannot be determined in advance. This implies that all +threads waiting on a single monitor must have the same semantics. If no +thread is waiting on the monitor, the notify operation is a no-op. -- cgit v1.2.3
