UDPSendCommand

class

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, destAddr/destPort may be left blank (send()), otherwise it must contain the destination for the packet (sendto()).
