menu_hook - set hooks for automatic invocation by applica-
tions
#include <menu.h>
int set_item_init(MENU *menu, void (*func)(MENU *));
void (*)(MENU *) item_init(const MENU *menu);
int set_item_term(MENU *menu, void (*func)(MENU *));
void (*)(MENU *) item_term(const MENU *menu);
int set_menu_init(MENU *menu, void (*func)(MENU *));
void (*)(MENU *) menu_init(const MENU *menu);
int set_menu_term(MENU *menu, void (*func)(MENU *));
void (*)(MENU *) menu_term(const MENU *menu);
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).
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).
curses(3), menu(3).

The header file <menu.h> automatically includes the header
file <curses.h>.
These routines emulate the System V menu library. They were
not supported on Version 7 or BSD versions.
