recv_io()

Receive an IO object (i.e. a file descriptor) from this IO channel. This only works if this IO channel is a Unix socket.

Raises SystemCallError if something went wrong.

send_io(io)

Send an IO object (i.e. a file descriptor) over this IO channel. This only works if this IO channel is a Unix socket.

Raises SystemCallError if something went wrong.
