[En-Nut-Discussion] fflush on input

[Brett Abbott]

Harald,

I use fflush to ensure the output goes to destination but I wouldnt want 
to lose incoming data already queued just because the output thread 
wanted to hurry up....  How should I be forcing output buffer to flush 
without affecting incoming stream data?

Many Thanks
Brett

Trevor,

fflush forces data output only. It does not flush the input
buffer, which is considered an error and will be changed.

fflush shall force output and discard the input.
