To make it explicit as question. You suggest to not use the C++ API at 
all in my application or just not for this use case?

Is it a good idea to mix usage of C and C++ API as long as it's not 
fully stable and then adapt later to full C++ usage? Do you know an 
example how to access the C API object?
