mitem_value(3X) 														   mitem_value(3X)

NAME
mitem_value - set and get menu item values SYNOPSIS
#include <menu.h> int set_item_value(ITEM *item, bool value); bool item_value(const ITEM *item); DESCRIPTION
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). 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. SEE ALSO
curses(3X), menu(3X). 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. AUTHORS
