2428 * WARNING: DO NOT COPY THIS CODE INTO YOUR APPLICATION
2430 * This code has a bug, which requires creating a separate
2431 * nl80211 socket to fix:
2432 * It is possible for a NL80211_CMD_NEW_SCAN_RESULTS or
2433 * NL80211_CMD_SCAN_ABORTED message to be sent by the kernel
2434 * before (!) we listen to it, because we only start listening
2435 * after we send our scan request.
2437 * Doing it the other way around has a race condition as well,
2438 * if you first open the events socket you may get a notification
2439 * for a previous scan.
2441 * The only proper way to fix this would be to listen to events
2442 * before sending the command, and for the kernel to send the
2443 * scan request along with the event, so that you can match up
2444 * whether the scan you requested was finished or aborted (this
2445 * may result in processing a scan that another application
2446 * requested, but that doesn't seem to be a problem).
2448 * Alas, the kernel doesn't do that (yet).
