63 * Create a TCP socket bound to the requested host and port.
64 * If the host is "ANY" the receving address will be set to INADDR_ANY.
65 * If the port is 0 the caller must find out the returned port number
66 * using a call to getsockname.
68 * XXX! The owner of the socket will be root rather then the user. This
