NAME         top

       set_item_value, item_value - set and get menu item values

SYNOPSIS         top

       #include <menu.h>

       int set_item_value(ITEM *item, bool value);
       bool item_value(const ITEM *item);

DESCRIPTION         top

       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 deselect it (second
       argument FALSE).

RETURN VALUE         top

       The function set_item_value returns one of the following:

       E_OK The routine succeeded.

       E_SYSTEM_ERROR
            System error occurred (see errno(3)).

       E_REQUEST_DENIED
            The menu driver could not process the request.

SEE ALSO         top

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

NOTES         top

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

PORTABILITY         top

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