int (*XESetCopyGC(display, extension, proc))()
      Display *display;
      int extension;
      int (*proc)();


display Specifies the connection to the X server.
extension Specifies the extension number.
proc Specifies the procedure to call when GC components are copied.


The XESetCopyGC() function defines a procedure to be called whenever a GC is copied. It returns any previously defined procedure, usually NULL.

When a GC is copied, your procedure is called with these arguments:

(*proc)(display, gc, codes)
	Display *display;
	GC gc;
	XExtCodes *codes;
