                             GError **error);

nm_device_wifi_request_scan has been deprecated since version 1.22 and should not be used in newly-written code.

Use nm_device_wifi_request_scan_async() or GDBusConnection.

Request NM to scan for access points on device . Note that the function returns immediately after requesting the scan, and it may take some time after that for the scan to complete.

Parameters

device	a NMDeviceWifi
cancellable	a GCancellable, or `NULL`
error	location for a GError, or `NULL`

Returns

TRUE on success, FALSE on error, in which case error will be set.

                                gpointer user_data);

Request NM to scan for access points on device . Note that callback will be called immediately after requesting the scan, and it may take some time after that for the scan to complete. This is the same as nm_device_wifi_request_scan_async except it accepts options for the scanning. The argument is the dictionary passed to RequestScan() D-Bus call. Valid options inside the dictionary are: 'ssids' => array of SSIDs (saay)

To complete the request call nm_device_wifi_request_scan_finish().
