The input maxsize is written to outbuf+0. The total amount of data written to the output starting at offset 0x0, is written to outbuf+4. Outbuf+8 is zero when the buffer contains no actual received data, 1 otherwise. Therefore, when the output contains no actual received data the size value at outbuf+4 is set to 0xC.
This returns beacon data for all UDS wifi beacons received by this system, with the specified wlancommID+ID8. See also the scaninput struct.

Description

This returns beacon data for all UDS wifi beacons received by this system, with the specified wlancommID+ID8. See also the scaninput struct.

Official user processes create a new event handle which is then passed to this command. However, those user processes don't save that handle anywhere afterwards.

This command can only be used when not connected to a network.
