TibrvQueueGroup::dispatch()
Method
Declaration
virtual TibrvStatus dispatch();
Purpose
Dispatch an event from a queue group; if no event is ready, block.
Remarks
If any queue in the group contains an event, then this call searches the queues in priority order, dispatches an event from the first non-empty queue that it finds, and then returns. If all the queues are empty, then this call blocks indefinitely while waiting for any queue in the group to receive an event.
When searching the group for a non-empty queue, this call searches according to the priority values of the queues. If two or more queues have identical priorities, subsequent dispatch and poll calls rotate through them in round-robin fashion.
