NAME
     menu_hook:    set_item_init,    item_init,    set_item_term,
     item_term,    set_menu_init,    menu_init,    set_menu_term,
     menu_term  -  assign   application-specific   routines   for
     automatic invocation by menus

SYNOPSIS
     #include <menu.h>

     int set_item_init(MENU *menu, void (*func)(MENU *));
     void (*)(MENU *) item_init(MENU *menu);

     int set_item_term(MENU *menu, void (*func)(MENU *));
     void (*)(MENU *) item_term(MENU *menu);
     int set_menu_init(MENU *menu, void (*func)(MENU *));
     void (*)(MENU *) menu_init(MENU *menu);

     int set_menu_term(MENU *menu, void (*func)(MENU *));
     void (*)(MENU *) menu_term(MENU *menu);

DESCRIPTION
     set_item_init assigns the application-defined function to be
     called  when  the  menu is posted and just after the current
     item changes.  item_init returns a pointer to the item  ini-
     tialization  routine, if any, called when the menu is posted
     and just after the current item changes.

     set_item_term assigns an application-defined function to  be
     called when the menu is unposted and just before the current
     item changes.  item_term returns a pointer to  the  termina-
     tion  function, if any, called when the menu is unposted and
     just before the current item changes.

     set_menu_init assigns an application-defined function to  be
     called  when  the  menu is posted and just after the top row
     changes on a posted menu.  menu_init returns  a  pointer  to
     the  menu  initialization  routine,  if any, called when the
     menu is posted and just after  the  top  row  changes  on  a
     posted menu.

     set_menu_term assigns an application-defined function to  be
     called when the menu is unposted and just before the top row
     changes on a posted menu.  menu_term returns  a  pointer  to
     the  menu  termination routine, if any, called when the menu
     is unposted and just before the top row changes on a  posted
     menu.

RETURN VALUE
     Routines that return pointers always return NULL  on  error.
     Routines that return an integer return one of the following:
     E_OK           - The routine returned successfully.
     E_SYSTEM_ERROR - System error.
