Yes, that's why I mentioned your name. >Ugly, only half-implemented, but better: a hook-based pseudoconsole >system for Windows. This is what I was holding out for. The last time it came up here, people seemed vehemently opposed to the idea since implementations that do this (like the Console app and a couple of libraries floating around) seem to have to poll the console looking for data and that could result in data loss. I have had code (not mine) sitting in my Cygwin directory for years which does this but I couldn't 100% convince myself that the detractors for this idea weren't right. Does your code work around this? 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
