Miscellaneous Library Functions                     menu_hook(3X)



NAME
     menu_hook - set hooks for automatic invocation  by  applica-
     tions

SYNOPSIS
     #include 
     int set_item_init(MENU *menu, Menu_Hook func);
     Menu_Hook item_init(const MENU *menu);
     int set_item_term(MENU *menu, Menu_Hook func);
     Menu_Hook item_term(const MENU *menu);
     int set_menu_init(MENU *menu, Menu_Hook func);
     Menu_Hook menu_init(const MENU *menu);
     int set_menu_term(MENU *menu, Menu_Hook func);
     Menu_Hook menu_term(const MENU *menu);

DESCRIPTION
     These functions make it possible to set hook functions to be
     called  at  various  points  in  the automatic processing of
     input event codes by menu_driver.

     The function set_item_init sets  a  hook  to  be  called  at
     menu-post  time  and  each  time  the  selected item changes
     (after the change).  item_init returns the current item init
     hook, if any (NULL if there is no such hook).

     The function set_item_term sets  a  hook  to  be  called  at
     menu-unpost  time  and  each  time the selected item changes
     (before the change).  item_term  returns  the  current  item
     term hook, if any (NULL if there is no such hook).

     The function set_menu_init sets  a  hook  to  be  called  at
     menu-post  time  and  just  after  the  top  row on the menu
     changes once it is posted.  menu_init  returns  the  current
     menu init hook, if any (NULL if there is no such hook).

     The function set_menu_term sets  a  hook  to  be  called  at
     menu-unpost  time  and  just  before the top row on the menu
     changes once it is posted.  menu_term  returns  the  current
     menu term hook, if any (NULL if there is no such hook).

RETURN VALUE
     Routines that return pointers return NULL on  error.   Other
     routines return one of the following:

     E_OK The routine succeeded.

     E_SYSTEM_ERROR
          System error occurred (see errno).
