To clarify my position: I have done some general programming under DOS/Windows,
including stdio, in which I know it is easy to open and read "NUL:", but I have
less experience of the file-handle APIs that are (AFAIK) much more widely used,
and cannot definitively answer this question. From what little knowledge and
experience I have both as a programmer and as a user, my impression is that
devices (including NUL) would often not be supported.
I don't know what Branko's position of authority is on the matter. I reacted
based on the impression that he was as unqualified as I am; apologies if this
is not so.
