The read failed with WSAECONNRESET, which I take as "will not work".

But I would be glad to hear, that it will work, and that I have to only find out what I did wrong.

Sorry I wasn't as clear as I could be, I'm only using sockets for what I would like to use named pipes for. I use regular win32 ReadFile in a thread currently to receive output on stdout/err and was hoping that this would fit nicely into the asio model too and let me remove this code and the neccessary synchronisation..
