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(3CURSES)).
item_value() returns the select value of item, either TRUE (selected) or FALSE (unselected).
Return Values
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.
