If you are trying to add functionality to cygwin to allow fd passing then you shouldn't be using this function. It is not intended for use with cygwin-specific things like unix-domain-sockets. Those really exist only in the cygwin domain and they are already associated with an fd. If you are attempting to do this as a user program rather than as a modification to the cygwin DLL, then you are probably out-of-luck. cgf -- 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/
