mitem_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).
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.
