How the BrdRecvScanner is
Initialized
The device-independent scan task initialization is outlined in Device-Independent
Scan Task Initialization§
. The initialization is performed on
startup of the scan task. The following initialization is specific to the
BrdRecvScanner:
- reads in debug device and opens file pointer to it.
- opens a socket connection to the specified port number (see service
name).
- sets the socket option for re-use. This allows other programs running
on the same system to receive the IP multicast datagrams as well.
- joins the specified IP multicast group (see hostname).
