SYNOPSIS

int set_item_value(ITEM *item, int bool);

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.
