NAME
	  glXGetCurrentDisplay - get display for current context


     C SPECIFICATION
	  Display * glXGetCurrentDisplay( void )


     DESCRIPTION
	  glXGetCurrentDisplay returns the display for the current
	  context. If no context is current, NULL is returned.

	  glXGetCurrentDisplay returns client-side information.	It
	  does not make	a round	trip to	the server, and	therefore does
	  not flush any	pending	events.

     NOTES
	  glXGetCurrentDisplay is only supported if the	GLX version is
	  1.2 or greater.
