This is not really related to your question, but your wording makes me
curious:  Is D on Windows somehow tied to DMC?  Is that different to
standard C?

You'd think that would be a common enough situation to warrant having a
function in the Windows API doing just that -- like POSIX' fdopen().  I
mean, isn't FILE* the de facto file handle standard in the C world?
