NAME
     glutMenuDestroyFunc -- Destruction callback for menus.

LIBRARY
     OpenGLUT - menucallback

SYNOPSIS
     #include <openglut.h>

     void
     glutMenuDestroyFunc(void( *callback )( void ));

PARAMETERS
      callback	   Client menu destruction hook.

DESCRIPTION
     When a menu is destroyed, OpenGLUT will call this hook, if defined on that menu.

     This callback is  not   bound to any window.

     This callback  is	 bound to a specific menu.

CAVEATS
     For emphasis, we repeat: This callback does not bind to any window.

TODO
     What on Earth is rationale for this feature? Menus should only be destroyed when we ask them
     to be destroyed, or when their window is destroyed. In the former case, we already know that
     the menu is being destroyed because we requested it.  In the latter case, it is easy for the
     client to track that if they care, via window-destruction callbacks.
