# mitem_value 3x

## 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.

## NOTES

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

## PORTABILITY

           These  routines  emulate  the System V menu library.  They
           were not supported on Version 7 or BSD versions.
