Create a parallel socket.
Connect to the named service at address addr. Use tcpwindowsize to specify the size of the receive buffer, it has to be specified here to make sure the window scale option is set (for tcpwindowsize > 65KB and for platforms supporting window scaling). Returns when connection has been accepted by remote side. Use IsValid() to check the validity of the socket. Every socket is added to the TROOT sockets list which will make sure that any open sockets are properly closed on program termination.
