I'm not sure I'd describe this behaviour as "inconsistent".
It's not uncommon to use the same parameter in both directions,
so passing the buffer length in, and the actual length back is
not unreasonable.

I'd say that the basic problem here is that the behaviour is not
documented properly.  (Like so much else!)
I'd suggest that:

Robert> adding one line before the read will fix your problem:
Robert>         len = sizeof(value);

this is the correct approach, and we just need to document it.
