glutMenuStatusFunc(3GLUT)	     GLUT	     glutMenuStatusFunc(3GLUT)

NAME
       glutMenuStatusFunc - sets the global menu status	callback.

SYNTAX
       void glutMenuStatusFunc(void (*func)(int	status,	int x, int y));
       void glutMenuStateFunc(void (*func)(int status));

ARGUMENTS
       func	 The new menu status (or state)	callback function.

DESCRIPTION
       glutMenuStatusFunc  sets	the global menu	status callback	so a GLUT pro-
       gram can	determine when a menu is in use	or not.	 When  a  menu	status
       callback	  is   registered,   it	  will	 be   called  with  the	 value
       GLUT_MENU_IN_USE	for its	value parameter	when pop-up menus are  in  use
       by   the	 user;	and  the  callback  will  be  called  with  the	 value
       GLUT_MENU_NOT_IN_USE for	its status parameter when pop-up menus are  no
       longer  in  use.	The x and y parameters indicate	the location in	window
       coordinates of the button press that caused the menu to go into use, or
       the  location  where the	menu was released (may be outside the window).
       The func	parameter names	the callback function.	Other  callbacks  con-
       tinue  to operate (except mouse motion callbacks) when pop-up menus are
       in use so the menu status callback allows a program to  suspend	anima-
       tion  or	other tasks when menus are in use. The cascading and unmapping
       of sub-menus from an initial pop-up menu	does not generate menu	status
       callbacks. There	is a single menu status	callback for GLUT.

       When  the  menu status callback is called, the current menu will	be set
       to  the	initial	 pop-up	 menu  in  both	  the	GLUT_MENU_IN_USE   and
       GLUT_MENU_NOT_IN_USE  cases. The	current	window will be set to the win-
       dow from	which the initial menu was popped up from, also	in both	cases.

       Passing NULL to glutMenuStatusFunc disables the generation of the  menu
       status callback.

       glutMenuStateFunc  is  a	 deprecated  version of	the glutMenuStatusFunc
       routine.	The only difference is	glutMenuStateFunc  callback  prototype
       does not	deliver	the two	additional x and y coordinates.
