item_value3menu
Set and get menu item values
Part of menu_value(3menu).
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:
|
The routine succeeded. |
|---|---|
|
System error occurred (see errno(3)). |
|
The menu driver could not process the request. |
Portability
These routines emulate the System V menu library. They were not supported on Version 7 or BSD versions.
