Ah ok, thanks for resending.
AFAIK only named pipes can be used/opened for win32 overlapped i/o.
In the entry for CreatePipe, MSDN says: Anonymous pipes are implemented using a named pipe with a unique name. Therefore, you can often pass a handle to an anonymous pipe to a function that requires a handle to a named pipe. I haven't tried it, however.
Is it possible to inherit sockets as stdin/out/err Handles for CreateProcess? I tried to write a small testcase yesterday, that 1. creates a connected socket pair, 2. derives a inheritable handle (DuplicateHandle) from the first socket, 3. closes the first socket, 4. creates a child process with the handle as stdout handle, 5. closes the handle, and 6. reads from the second socket.
The read failed with WSAECONNRESET, which I take as "will not work".
Yeah, I don't know the answer, sorry. You might try not closing the socket handles and see if that makes a difference. Cheers, Chris
