popen3 child_stdin

[ddoc]

It was brainfade.  
The function returns a tuple, of course.
It works, and solves one Linux task I had been contemplating for a while, 
but doesn't of itself accomplish a job I want to do in Windows

I should be able to automate a DOS program - or rather seize its interface 
and control what goes in as from a keyboard, and catch what comes out as if 
to the screen, thus programattically determining what gets typed to it and 
what gets shown to a notional user, but I suspect I need to use pipes 
rather than the popen setup.

Does anyone know an example of this being done (to a DOS/console program) 
that is available for inspection?
