Hi,
I apologize for this message being Way Off Topic, but I'm at a loss for
how to continue.

The problem is, how do I test whether anything has been typed to stdin
without blocking the program if the input buffer is empty? Of course,
the simple things don't work. I've tried getc(), fgetc(), gets(),
scanf(), .... They all block until a '\n' is typed. I just want the test
to fail and continue if nothing is waiting in the buffer.

Any ideas from you C++ gurus out there?

TIA,
Thom
