In my old days of DOS programming there was a function called kbhit that did the
trick which returned TRUE if the
keyborad had been used. Now, that was C so you might need to add (prepend) an
underscore to be able to "see" it from C++
code ( _kbhit() ). And of course WinNT has nothing to do with DOS, right? but
then if I were to bet on it, I would say chances are
 pretty high it will work anyways

If Iīm not mistaking it, select should be available with winsockets but I donīt
know if the winsocket implementation is complete and
seamless enough to integrate with stdin (under BSD unixs is also a system call).
but may be someone may comment. It would
be nice for portability issues.

Well, I guess I have to admit it. I'm not writing this on an SGI. I'm on WinNT
using VC++ 6.0 and VegaNT.

I can't find anything on this machine that defines the select() function. And
the read() function still blocks until '\n' is entered. I did find an
_filelength() function which I thought might work, but it just returns an
error whether anything is on the input buffer or not.
