but he doesn't want to append to the file if it exists and he doesn't want
to replace the file if it exists... which is (in this universe)
impossible. This isn't a windows program is it? cos that sounds like some
weird thing that they'd try :)
unless he's trying to overwrite the file (or parts of it)... in which case
just open it in append mode and seek to the start (or whereever). but i
can't think of a good reason to do that.
