Manpages - mitem_value.3x

set_item_value, item_value - set and get menu item values

#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.

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

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

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