   Sorry, I don't understand.   
      
   First, I'm only interested in C90, so there's only the 3 handles   
   to be concerned with, and the concept already exists.   
      
   What I want to do is make use of existing practice to give   
   applications somewhere to write to.   
      
   It is my C library, PDPCLIB, that will do the actual writing.   
   Actual C90 applications will not be aware that a named   
   pipe is involved. There is no need to provide applications   
   with a GetStdHandle API or any such thing. It's all hidden   
   in the C library.   
      
   Existing practice is a "con" pipe that ends up on a DOS   
   window. That's an interesting setup.   
      
   But I only need to know the interface that the Windows   
   NE executable sees in such an arrangement.   
      
   I will be marrying the fairly-standard 16-bit Windows NE   
   executable up to something completely different.   
      
   Let's start with PDOS/PM16.   
      
   When operating in this "con pipe" mode, what does the   
   NE executable see/do? Does it call a DLL? What's the   
   name of the DLL?   
      
   PDOS/PM16 will provide an artificial DLL to satisfy that.   
      
   But what is the actual DLL call? Is it OpenFile("pipe:con")   
   or an INT 21H or what?

   Sure. Let me start with PM16 and I'll see if CM16 is   
   useful another day. At least I'll actually have something   
   to be backward-compatible with when I get there!   
      
   Thanks. Paul.
