I forgot to add one bit of data. Unless you go out of your way to change it, Cygwin's select can't wait for an fd > 63. It's basically a bit mask. So, there are two limitations: 1) the number of handles that you can wait for with WaitForMultipleObjects() and 2) the size of Cygwin's fd_set. cgf -- 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
