11.3.2: Receiving an Event Set

The rtems.event_receive directive is used by tasks to accept a specific input event condition. The task also specifies whether the request is satisfied when all requested events are available or any single requested event is available. If the requested event condition is satisfied by pending events, then a successful return code and the satisfying event set are returned immediately. If the condition is not satisfied, then one of the following situations applies:

By default, the calling task will wait forever for the event condition to be satisfied.
Specifying the RTEMS.NO_WAIT option forces an immediate return with an error status code.
Specifying a timeout limits the period the task will wait before returning with an error status code.
