You prefer structure with many-many fields to the long-long list of DPB
patrameters. This approach has one disadvantage - when you need to add more
members to such Init structure (i.e. more parameters to DPB), you need to
take care about backward compatibility. Here arrive sizeof(struct Init) as
it's first element (supposing new elements are added in the end of a
structure) or it's version, also stored in the begining of that structure.
All that doable, but on contrary with DPB forces you to have one more
action - initialize that first value. With existing DPB approach new
parameters are simply added - and that's all, people may use it.

From what language are you calling C API? There are many different wrappers,
making life easier - liek IBPP, for example.
