TibrvQueue::poll()
Method
Declaration
virtual TibrvStatus poll ();
Purpose
Dispatch an event, if possible.
Remarks
If the queue is not empty, then this call dispatches the event at the head of the queue, and then returns. If the queue is empty, then this call returns immediately.
When the call dispatches an event, it returns the status code TIBRV_OK. When the call does not dispatch an event, it returns the status code TIBRV_TIMEOUT.
This call is equivalent to timedDispatch(0).
