But isn't that exactly what RPG does provide you? What big advantages 
brings a wrapper for these functions?

This means that you have at least two calls. And a lot of problems.

How would you pass the data? For performance reasons, a pointer would be 
best. For security reasons (you would have to re-build the 
CPF4131-protection), an external described data structure would be better.

I can't see the big advantage that would justify the work and overhead.
