set_item_value, item_value - set and get menu item values

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).

E_OK
  The routine succeeded.
E_SYSTEM_ERROR

E_REQUEST_DENIED
  The menu driver could not process the request.
