  event_return
	      Returns the matched event's associated structure into this client-supplied structure.

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.
