MessageQueueTerminate Method

Terminates the message queue.

Any messages that are already in the queue when this method is called will be processed before the queue is terminated. This method initiates the termination and returns immediately; it does NOT wait for the termination to complete before returning. It is safe to call this method from any thread, including the thread that is processing the message queue. To wait for termination to complete, call TerminateAndWait instead. If the queue is not running when this method is called, the termination request will still be posted. That means that queue processing, once restarted, will terminate once it reaches this point in the queue.
