NAME

       mitem_value - set and get menu item values


SYNOPSIS

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


DESCRIPTION

       If  you  turn  off  the menu option O_ONEVALUE (e.g., with
       set_menu_opts or menu_opts_off;  see  menu_opts(3x)),  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 dese-
       lect it (second argument FALSE).


RETURN VALUE

       The function set_item_value returns one of the following:

       E_OK The routine succeeded.

       E_SYSTEM_ERROR
            System error occurred (see errno).

       E_REQUEST_DENIED
            The menu driver could not process the request.

       The header file <menu.h> automatically includes the header
       file <curses.h>.
