And so, the next question is: Which OS's support setvbuf()?
I'm on Ubuntu GNU/Linux. I do the following and I see:
~ [6] cd /usr/include/
/usr/include [7] grep setvbuf *.h
stdio.h:/* The possibilities for the third argument to `setvbuf'. */
stdio.h:extern int setvbuf (FILE *__restrict __stream, char *__restrict __buf,
So, some versions of Linux apparently have it.
And, for MS Windows, you might look here:

So, MS Windows seems to support it.
