I think you'll find that this behavior is implementation defined. ALMOST
all versions I've used deleted the existing file and created a new,
empty file with the same name (or truncated the existing file to zero
bytes; I can't tell the difference :). Anyway, since you're creating an
implementation, you're free to decide what it does.
