Re: SetNamedPipeHandleState problems??

OK. Problem is you need a handle to a pipe, not a file. Yes, the doc states that it can be
used with a handle returned by CreateFile, but that's only because CreateFile can be used to
get a handle to the client end of a named pipe. Pipe != File.

Perhaps you should state what it is you're *actually* trying to accomplish? Or read more
about named (or anonymous) pipes. Or files.
