As a "mod" I can safely say that any topic which discusses how not to use Cygwin can safely be considered to be off-topic. However, if you're talking about Cygwin's version of spawn which is (IMO misguidedly) intended to mimic the spawn* functions in Windows then, if you are trying to use pipes, you will probably need to investigate how to use close-on-exec to close one side of the pipe while passing the other to the subprocess. You should be able to play games with fds using dup2, dup, and close-on-exec to force a pipe to be the stdin or stdout of a subprocess. It would be tricky but doable. http://pubs.opengroup.org/onlinepubs/009695399/functions/fcntl.html http://pubs.opengroup.org/onlinepubs/009695399/functions/dup2.html http://msdn.microsoft.com/en-US/library/20y988d2%28v=vs.80%29.aspx -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
