rewind(stdin); ? Right or Wrong?

As fflush(stdin); is wrong. Some one suggests using rewind(stdin) to eliminate input buffer and also clear error state of the stream. Is that right?

I used Dev-C++ to compile this code, and it really works. Is it right to use rewind(stdin); ?

As for as I know, rewind(fp) is equivalent to fseek(fp, 0L, SEEK_SET); clearerr(fp). So I guess this is another wrong thing to clear input buffer.

It's recommended by Microsoft

So I'm tempted to say it's probably the wrong thing to do :)

Of course if stdin isn't a keyboard, you'd get "interesting" results.

You can't seek on console streams, so I dare say it's a wrong thing to do, unless stdin has been redirected to a file. There is no ISO C way of finding out whether this has happened, though I believe there's a POSIX way.

Hell no.

Calling rewind on stdin is perfectly legal. The behavior is erratic though, so it's not recommended in the general case.
