That's a nice trick: each time the write-end of the pipe is duplicated so is the handle to a named event created when the pipe was created; so, if you try and fail to open the event, all instances of the write-end have been closed. Very simple and it survives applications being killed via the task manager too. I'll see if I can use that trick to simplify the UNIX domain socket patch I submitted. I can't immediately see how, since I want the code to block until something in particular happens, but it would simplify the detection of the last close. Thanks, // Conrad p.s. I like the name of the event too: "stupid_pipe" ;-)
