This I had tried even before posting the question :)

In my original post I call:
As for the program based on SteveG's code, I tried to keep
his code as intact as possible, so I didn't close the input
handle in it.

Oh, I missed this. My WinApi program creates pipes with:
SECURITY_ATTRIBUTES.bInheritHandle = true;
in order for the handles to be properly inherited in the
child process. That must be my problem. The only other way
to do it is to use the DuplicateHandle function which will
create in inherarable duplicate of the original handle, that
can then be passed to the CreateProcess. The original handle
will remain non-inheritable and should trigger EOF on clo-
Thank you for your investigation. I'll try duplicating the
handles and report the results.
