View In Hierarchy

An interface for performing some basic kinds of I/O (particularly that I/O which might be useful for twisted.pair.tuntap-using code).

def sendUDP(datagram, address): (source)

Send a datagram to a certain address.

Parameters	datagram	The payload of a UDP datagram to send. (type: `bytes`)
	address	The destination to which to send the datagram. (type: `tuple` of (`bytes`, `int`))
Returns	The 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.

Parameters	fileno	A file descriptor representing a tunnel device which the datagram was either sent via or will be received via. (type: `int`)
	host	The IPv4 address at which the datagram will be received. (type: `bytes`)
	port	The UDP port number at which the datagram will be received. (type: `int`)
Returns	A `socket.socket` which can be used to receive the specified datagram.
