All good points. I knew I’d end up needing to change all the stubs again.
I think the answer is yes to all.  The types (except const'ness) were just
following the types of the data which are being passed in from dl-load and
also the convention used for return types of other hooks.

If I change the type of len then I expect I should change the type of the
original variable in dl-load as well.
