One possibility is to use a combination of real time signals (which queue) and signalfd to provide a select()'able interface to those signals. Early test code on Linux shows promise. I did a quick check and it doesn't appear that Cygwin supports the signalfd (or eventfd) interface. Are there any plans to include this? If not what should I look at that Cygwin does support that could provide similar functionality? Thanks in advance for all your answers. bob -- 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
