Linux Server Hacks, Volume Two: Tips & Tools for Connecting, Monitoring, and Troubleshooting
This command receives a datagram directed to the local name associated with the ncb_num value. If ncb_num is 0xFF, this command receives datagrams directed to any local name. The local name can be either a group name or a unique name. If no receive datagram command is pending when a datagram is sent, the data is lost. If the supplied buffer is too small, the message "incomplete error," NRC_INCOMP (0x06), occurs and the data is truncated to fill the buffer.
