I don't quite understand the problem. All the prototypes and
structures that are directly needed are in your the .h file.

If you are talking about the code to implement server side
objects, then you can do create an initial implementation of this

 orbit-idl --skeleton_impl

<> is right for sequences. You can also declare arrays like
in C with [] and slightly different sytax.
