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  simultane-
       ously 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).

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.

SEE ALSO
       curses(3X), menu(3X).

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.
