Description

The XCheckTypedEvent() function searches the event queue and then any events available on the server connection for the first event that matches the specified type. If it finds a match, XCheckTypedEvent() removes that event, copies it into the specified XEvent structure, and returns True . The other events in the queue are not discarded. If the event is not available, XCheckTypedEvent() returns False , and the output buffer will have been flushed.
