fflush just cares about the buffer in libc, not about any buffering in
the OS (not that I am aware of that any OS buffers screen outputs,
though). if you just care about the libc buffer, there is no problem
with setvbuf, as this function is ANSI, and as it is just about when
libc passes the data to the OS, perfectly portable. I remember having
seen this function already in Turbo C 2.0 (And that is years before
Turbo C++ 2.0)
