def sendmsg(socket, data, ancillary=[], flags=0): (source)

Send a message on a socket.

Parameters	socket	The socket to send the message on. (type: `socket.socket`)
	data	Bytes to write to the socket. (type: bytes)
	ancillary	Extra data to send over the socket outside of the normal datagram or stream mechanism. By default no ancillary data is sent. (type: `list` of `tuple` of `int`, `int`, and `bytes`.)
	flags	Flags to affect how the message is sent. See the `MSG_` constants in the sendmsg(2) manual page. By default no flags are set. (type: `int`)
Returns	The return value of the underlying syscall, if it succeeds.

def recvmsg(socket, maxSize=8192, cmsgSize=4096, flags=0): (source)

Receive a message on a socket.

Parameters	socket	The socket to receive the message on. (type: `socket.socket`)
	maxSize	The maximum number of bytes to receive from the socket using the datagram or stream mechanism. The default maximum is 8192. (type: `int`)
	cmsgSize	The maximum number of bytes to receive from the socket outside of the normal datagram or stream mechanism. The default maximum is 4096. (type: `int`)
	flags	Flags to affect how the message is sent. See the `MSG_` constants in the sendmsg(2) manual page. By default no flags are set. (type: `int`)
Returns	A named 3-tuple of the bytes received using the datagram/stream mechanism, a `list` of `tuple`s giving ancillary received data, and flags as an `int` describing the data received.

def getSocketFamily(socket): (source)

Return the family of the given socket.

Parameters	socket	The socket to get the family of. (type: `socket.socket`)
Returns	(type: `int`)

Function	sendmsg	Send a message on a socket.
Function	recvmsg	Receive a message on a socket.
Function	getSocketFamily	Return the family of the given socket.
