I totally agree using memset in this case would the correct approach. I came
to this sample program by simplifying my original program (that loop was
formatting the buffer before it was sent to the output file) so guess I
wasn't even concentrating on the loop but on the write function itself.

I guess my question is a hypothetical one...

Why does program that only uses an I/O function and does nothing but I/O
consume so much CPU?
