int silc_net_create_connection(const char *local_ip, int port, 
                                   const char *host);

    Creates a connection (TCP/IP) to a remote host. Returns the connection
    socket or -1 on error. This blocks the process while trying to create
    the connection. If the `local_ip' is not NULL then this will bind
    the `local_ip' address to a port before creating the connection.  If
    it is NULL then this will directly create the connection.
