Wireless Netlink

The nl80211 module provides functions for interacting with the nl80211 netlink interface for wireless networking configuration and management.

Functions can be individually imported and directly accessed using the named import syntax:

import { error, request, listener, waitfor, const } from 'nl80211';

// Send a nl80211 request
let response = request(const.NL80211_CMD_GET_WIPHY, 0, { wiphy: 0 });

// Create a listener for wireless events
let wifiListener = listener((msg) => {
    print('Received wireless event:', msg, '\n');
}, [const.NL80211_CMD_NEW_INTERFACE, const.NL80211_CMD_DEL_INTERFACE]);

// Wait for a specific nl80211 event
let event = waitfor([const.NL80211_CMD_NEW_SCAN_RESULTS], 5000);
if (event)
    print('Received scan results:', event.msg, '\n');

Alternatively, the module namespace can be imported using a wildcard import statement:

import * as nl80211 from 'nl80211';

// Send a nl80211 request
let response = nl80211.request(nl80211.const.NL80211_CMD_GET_WIPHY, 0, { wiphy: 0 });

// Create a listener for wireless events
let listener = nl80211.listener((msg) => {
    print('Received wireless event:', msg, '\n');
}, [nl80211.const.NL80211_CMD_NEW_INTERFACE, nl80211.const.NL80211_CMD_DEL_INTERFACE]);

Additionally, the nl80211 module namespace may also be imported by invoking the ucode interpreter with the -lnl80211 switch.
