sockaddr_in

sockaddr_in (port, addr_string)

pack_sockaddr_in (port, addr_string)

• Takes a port number and a four-byte addr_string (as returned by inet_aton) and returns the socket address structure including those arguments packed with the AF_INET argument. This structure is normally what you need for the arguments in bind, connect, and send, and is also returned by getpeername, getsockname, and recv.
