MENU_ITEM_VALUE(3CURSES) Curses Library Functions MENU_ITEM_VALUE(3CURSES)
menu_item_value, set_item_value, item_value - set and get menus item
values
cc [ flag... ] file... -lmenu -lcurses [ library... ]
#include <menu.h>
int set_item_value(ITEM *item, int bool);
int item_value(ITEM *item);
Unlike single-valued menus, multi-valued menus enable the end-user to
select one or more items from a menu. set_item_value() sets the
selected value of the item -- TRUE (selected) or FALSE (not
selected). set_item_value() may be used only with multi-valued
menus. To make a menu multi-valued, use set_menu_opts or
menu_opts_off() to turn off the option O_ONEVALUE. (See
menu_opts(3CURSES)).
item_value() returns the select value of item, either TRUE (selected)
or FALSE (unselected).
set_item_value() returns one of the following:
E_OK
The routine returned successfully.
E_SYSTEM_ERROR
System error.
E_REQUEST_DENIED
The menu driver could not process the request.
