Hi Denis, > I sent my own take on this. I was playing around with it yesterday. Which is the exact same thing as I first proposed in "[PATCH] genl: Add utility function no append nested attribute into a message" plus the nested of nested stuff I added in the other one via the fixed table I advised also (on which I am still waiting feedback). That's fine. But such API was requested to be moved into the "builder" type of thing like DBus does. > The only thing I'm not sure about is whether the nested message length > is aligned or not.

So guys what's the decision then: which API is the right one here? Can we clear this up once and for all? There are dependent code that cannot proceed until this is over. This is a show-stopper.
