Hello guys, it's been a while, but...
> What's bugging me is that 0 and O_EXCL give the same answer, and > O_TRUNC and O_TRUNC | O_EXCL give the same answer, This is ok, as (iirc) O_EXCL only has effect in the presence of O_CREAT. (a comment to this effect would help here, as well as perhaps links to the CreateFile and open specs) > but O_CREAT and O_CREAT | O_EXCL give different answers, > as do O_CREAT | O_TRUNC and O_CREAT | O_TRUNC | O_EXCL. See above. > I'm also pretty suspicious of both O_CREAT | O_EXCL and > O_CREAT | O_TRUNC | O_EXCL giving the same answer. O_CREAT | O_EXCL is effectively "create, but fail if the file exists", which is the behaviour specified by CREATE_NEW. Adding O_TRUNC to this combination, which can only apply to a successfully opened existent file, can have no impact afaics.
