class

Control info for connecting an UDP socket. To connect a socket, send a message to the Udp module with kind=UDP_C_CONNECT and an UdpConnectCommand attached. If the socket does not exist, it will be created.

Both the address and the port must be filled in.

// Control info for sending data via UDP. To send a packet, send it to
// the ~Udp module with kind=UDP_C_SEND and an ~UDPSendCommand attached.
//
// UDP_C_SEND/~UDPSendCommand models both the Unix send() and sendto() calls.
// If the socket is connected, tags not required, or destAddr/destPort may be left blank (send()),
// otherwise it must contain the destination for the packet (sendto()).
