Sure, but René meant the opposite case: When fewer bytes than requested
were written, then you shouldn't retry to write more! That is, you should
exit the loop when write(fd, buf, n) does not return n.

I still find your code unnecessarily hard to read. In particular, you
should extract the non-problematic case out of the loop. If you followed
my suggestion elsewhere in the thread, you wouldn't have to write any
conditionals that 'break' out of a loop.
