     called whenever the menu is posted and also just after the current item
     changes.  This is set by the set_item_init() call.  The item_term() func-
     tion returns a pointer to the function that will be called before the
     menu is unposted and just before the current item changes, this pointer
     is set by the set_item_term() call.  The menu_init() functions returns a
     pointer to the function that will be called just before the menu is
     posted to the screen.  This pointer is set by the set_menu_init() func-
     tion call.  The menu_term() function returns a pointer to the function
     that will be called just after the menu has been unposted, this pointer
     is set by the set_menu_term() function.
