getsockname

See the current Perl documentation for getsockname.

Here is our local, out-dated (pre-5.6) version:

getsockname - retrieve the sockaddr for a given socket

getsockname SOCKET

Returns the packed sockaddr address of this end of the SOCKET connection.

    use Socket;
    $mysockaddr = getsockname(SOCK);
    ($port, $myaddr) = unpack_sockaddr_in($mysockaddr);
