You use int flags, but.. these are mutually exclusive operations, and
so flags is a misnomer. Just use an enum instead of a define, that way
we can use kdoc for documentation.

If no one is using these don't export them. I think you only use one of
these. In fact just remove the code from the ones which are not used.
