TibrvDispatchable::poll()
Method
Declaration
virtual TibrvStatus poll();
Purpose
Dispatch an event, if possible.
Remarks
If an event is ready to dispatch, then this call dispatches it, and then returns. If no events are waiting, then this call returns immediately.
When the call dispatches an event, it returns TIBRV_OK. When the call does not dispatch an event, it returns the status code TIBRV_TIMEOUT.
This call is equivalent to timedDispatch(0).
Both TibrvQueue and TibrvQueueGroup implement this method.
