mitem_value3menu

Set and get menu item values

Usage

#include <menu.h>
int set_item_value(ITEM *item, bool value);
bool item_value(const ITEM *item);

Overview

If you turn off the menu option O_ONEVALUE (e.g., with set_menu_opts or menu_opts_off; see opts(3MENU)), 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

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.
