XSetAfterFunction()					   XSetAfterFunction()

Name
  XSetAfterFunction – set a function called after all Xlib functions.

Synopsis
  int (*XSetAfterFunction(display, procedure))()
	Display *display;
	int (*procedure)();

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

  procedure Specifies the user-defined function to be called  after  each
	    Xlib  function.   This  function is called with one argument,
	    the display pointer.

Returns
  The previous after function.

Description
  All Xlib functions that generate protocol requests call what	is  known
  as  an  after	 function  after completing their work (the default after
  function does nothing).  XSetAfterFunction()	allows	you  to	 write	a
  function  to be called.  XSetAfterFunction() returns the previous after
  function.

  XSynchronize() sets an after function to make sure that the  input  and
  request buffers are flushed after every Xlib routine.

  For  more  information,  see	Volume One, Chapter 15, Other Programming
  Techniques.
