SYNOPSIS
cc [flag . . .] file -lmenu -lcurses [library . . .]
#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
initialization 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 termination
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
