I admit it gets a bit long, but maybe it should somehow
indicate that it returns a string?
Also, will there be some issues with memory (de-)allocation/ownership
handling for that string?

Hm, and this one is a number?
Possibly ugly and inconsistent, but I wonder if adding a _NR
to indicate that would make sense.
But either way this is kind of bikeshedding.
Also, it's only internal API anyway, so we can change it
any time, add what you think you need.
