It's ok as it is now. It was incorrect before. The connect doesn't return immediately and FD_ISSET (fd, &writefds) returns true when the connection is refused. See SUSv3: <quote http://www.opengroup.org/onlinepubs/007904975/functions/select.html> If a non-blocking call to the connect() function has been made for a socket, and the connection attempt has either succeeded or failed leaving a pending error, the socket shall be marked as writable. </quote> Corinna -- Corinna Vinschen Please, send mails regarding Cygwin to Cygwin Developer mailto:[EMAIL PROTECTED] Red Hat, Inc. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Bug reporting: http://cygwin.com/bugs.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
