Hmmm... both would be sufficient, of course. For just this single
purpose a callback could be less intrusive. But in general I like C APIs
where each(!) function stores detailed error information in the context
object and then just returns the numerical and less detailed return
code. The caller then can be happy just about the numerical return code
or call a getter to retrieve the detailed error message. So, in the
long-term I would like to see the second one also in POPT...
