From the original Amiga UNIX 2.1 manual. Some things it mentions may not be in this release.

NAME

menu_item_value: set_item_value, item_value - set and get menus item values

SYNOPSIS

#include <menu.h>

int set_item_value(ITEM *item, int bool);

int item_value(ITEM *item);

DESCRIPTION

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(3X)].

item_value returns the select value of item, either TRUE (selected) or FALSE (unselected).

RETURN VALUE

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.
