> Check line 192 for a call to the WaitForAvailableConsoleInput function.
I guess they expect hFile to be a console handle (which IS waitable). And my guess that they added the Peek intentionally to prevent the WaitFor call from slipping through (as we've seen it does, otherwise) on things that weren't supposed to be there (such as pipes). They probably know of a side effect of peeking a pipe, which makes the WaitFor API block on them (thus, still create a good cancellation point for the thread) -- again, as they would not expect a pipe there (but a good console handle; and if it isn't -- well, it's by design). But I'm only speculating here. On the other hand, I would not be surprised to learn that one team in MS would not know how to deal with the pipes and introduced a bug, easily. MS is a large company, and I witnessed such things to happen in teams of a much smaller scale, from my own experience. In our apps we use the Peek everywhere for pipe polling, and do not rely on anything else. And from Cygwin point of view, I was trying to deal with mixing native Windows things and UNIX, and it seems to be a big no-no, from the entire design point -- Cygwin is not a tool for be-friending Windows and Unix, rather a way to run your beloved GNU tools on a Windows box.
