Queue.Poll
Method
Visual Basic
NotOverrideable Public FunctionPoll()
Implements IDispatchable.Poll
C#
public bool 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 true. When the call does not dispatch an event, it returns false.
This call is equivalent to TimedDispatch(0).
