Every BSD manpage for three-argument open() I've seen doesn't show the
third argument as optional.  (BSD not to be confused with, for example,
Sun, which does show the third argument as optional.)  You'll normally
get away with omitting it (when not including O_CREAT), but that
doesn't make it optional.

Or is it supposed to be optional and the manpage is wrong?
