I did get Eric's test case working last night with only an addition of one or two hundred lines of extra code. I ended up fixing a long-standing bug in fhandler_base::read, and found a strange problem where fd's are inexplicably changed to textmode. I haven't tracked that one down yet. Then, as I was drifting off to sleep, I realized that my fix only goes 75% of the way towards getting full fifo behavior. So, I probably still won't be checking anything in anytime soon. cgf (Mr. Fifo) -- 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
