Network Programming for Microsoft Windows (Microsoft Professional Series)
NCBDGSENDBC
This command sends a broadcast datagram to every host on the LAN. Only those machines with an outstanding receive datagram command get the message. Also, if the local adapter has a pending receive datagram command, it receives its own message. Broadcast datagrams have the same size limitation mentioned in the NCBDGSEND entry. Table 22-12 describes the characteristics of the NCBDGSENDBC command.
