       set_item_value, item_value - set and get menu item values

SYNOPSIS

       #include <menu.h>
       int set_item_value(ITEM *item, bool value);

DESCRIPTION

       If you turn off the menu option O_ONEVALUE (e.g., with set_menu_opts or menu_opts_off; see
       opts(3MENU)),  the  menu  becomes  multi-valued;  that  is,  more  than   one   item   may
       simultaneously be selected.

       In  a multi_valued menu, you can used set_item_value to select the given menu item (second
       argument TRUE) or deselect it (second argument FALSE).
