set_item_value, item_value - set and get menu item values

SYNOPSIS DESCRIPTION RETURN VALUE PORTABILITY AUTHORS SEE ALSO

#include <menu.h>

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

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).

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.

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