How can I flush pending input so that a user's typeahead isn't read at the next prompt? Will fflush(stdin) work?

fflush is defined only for output streams. Since its definition of ``flush'' is to complete the writing of buffered characters (not to discard them), discarding unread input would not be an analogous meaning for fflush on input streams.
