def sendUDP(datagram, address): (source)

Send a datagram to a certain address.

ParametersdatagramThe payload of a UDP datagram to send. (type: bytes)
addressThe destination to which to send the datagram. (type: tuple of (bytes, int))
ReturnsThe local address from which the datagram was sent. (type: tuple of (bytes, int))
def receiveUDP(fileno, host, port): (source)

Return a socket which can be used to receive datagrams sent to the given address.

ParametersfilenoA file descriptor representing a tunnel device which the datagram was either sent via or will be received via. (type: int)
hostThe IPv4 address at which the datagram will be received. (type: bytes)
portThe UDP port number at which the datagram will be received. (type: int)
ReturnsA socket.socket which can be used to receive the specified datagram.
