| Function | recvmsg | Receive a message on a socket. |
| Function | getSocketFamily | Return the family of the given socket. |
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_

| 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 tuples
giving ancillary received data, and flags as an int
describing the data received. | |
Return the family of the given socket.
| Parameters | socket | The socket to get the family of. (type: socket.socket) |
| Returns | (type: int) | |
