Description
XCheckTypedWindowEvent() searches first the event queue, then any events available on the server connection, for an event that matches the
specified window and the specified event type. Events searched but not matched are not discarded.
XCheckTypedWindowEvent(), if the event is found, removes the event from the queue, copies it into the specified XEvent structure, and
returns True. It flushes the request buffer and returns False if the event is not found.
