XNextEvent()															      XNextEvent()

Name
  XNextEvent - get the next event of any type or window.

Synopsis
  XNextEvent(display, event_return)
	Display *display;
	XEvent *event_return;

Arguments
  display   Specifies a connection to an X server; returned from XOpenDisplay().

  event_return
	    Returns the event removed from the event queue.

Description
  XNextEvent() removes an event from the head of the event queue and copies it into an XEvent structure supplied by the caller.  If the event
  queue is empty, XNextEvent() flushes the request buffer and waits (blocks) until an event is received.  Use  XCheckMaskEvent()  or  XCheck-
  IfEvent() if you do not want to wait.
