Clean up the stream @var{stream} so that its buffer is empty. If
@var{stream} is doing output, force it out. If @var{stream} is doing
input, give the data in the buffer back to the system, arranging to

You need not clean a stream before using its descriptor for control
operations such as setting terminal modes; these operations don't affect
