You are on the right track; there is nothing difficult here but merely a bunch of moving parts to keep track of and understanding how they interact with each other. The SO articles i linked to earlier are very relevant and you should follow other links from their pages. That said there is one other crucial point to keep in mind when calling C++ from C.
