Function check_for_hostspec

options.c:3130–3156

Look for a HOST specification of the form "HOST:PATH", "HOST::PATH", or * "rsync://HOST:PORT/PATH". If found, *host_ptr will be set to some allocated * memory with the HOST. If a daemon-accessing spec was specified, the value * of *port_ptr will contain a non-0 port number, otherwise it will be set to * 0. The return value is a pointer to the PATH. Note that the HOST spec can * be an IPv6

 * be an IPv6 literal address enclosed in '[' and ']' (such as "[::1]" or
 * "[::ffff:127.0.0.1]") which is returned without the '[' and ']'. */
