}
Returns the remote address of the socket as a sockaddr string.
Example
TCPServer.open("127.0.0.1", 1440) {|serv| c = TCPSocket.new("127.0.0.1", 1440) s = serv.accept p s.getpeername #=> "\x02\x00\x82u\x7F\x00\x00\x01\x00\x00\x00\x00\x00\x00\x00\x00" }
If Addrinfo object is preferred over the binary string, use BasicSocket#remote_address.
