Will you take a look at what I designed at that time?
You will most probably not like it entirely, but it might be a good
The strategy we used was to re-design everything in C++,
object-oriented, and then code the resulting "proyection" onto C. The
modules each take opaque "handles" and all parameters are passed around
in their native binary form ---as opposed to converting back and forth
Just tell me and I will fetch the interfaces and send them.

Indeed. My proposal, almost four years ago
librrd_compat, with a suitable alias for old applications (or just librrd)
