Thank you for this.

As I recall, some posts to this list say that Windows provides
non-blocking i/o for sockets but not for files.

However, if non-blocking i/o for files were available, that
would be great.  Actually, all I care about is input.

Can anyone provide a definite answer to this question?

And please, if the answer is YES (hope it is), with
working sample code.


The threaded approach does not help me.  If the read blocks,
I do not know what to write.  (I am responding to a command
line prompt - I have to read it first.)
