Does it have morphs for facial expression?  If so, you'll need to somehow export each of those as 3ds or obj and Load Morph Target one-by-one in Poser to add them to the imported original mesh.

Otherwise, you really shouldn't need any bones for the head - maybe the eyes as they are usually treated as separate body parts.

C makes it easy to shoot yourself in the foot. C++ makes it harder, but when you do, you blow your whole leg off.
