Platform Independent layer between C++ and Objective C

[skooby]

I have my platform independent layer that I have done most of my coding in and want to port that to the iphone to offer a multi-platform environment. The difficulty I am having is sharing some of the objects between Objective C and C++.

For instance I have an abstracted platform independent layer like :
void VideoServices:: DrawPoly (...)
{
ExternDrawPoly_OPENGLES();
}

Which I would like to call the Objective C stuff for the lower implementation.

So in my ExternDrawPoly_OPENGLES() I call drawPoly() which is located in my .mm EAGLView.mm area.

Inside of my ExternDrawPoly(...) in EAGLView.mm I want to reference the EAGLView implementation object but it gives me a warning and then it crashes when the code is being run.

I imagine that my difficulty is getting a pointer to the EAGLView object, but not quiet sure how to get it.

Any help would be appreciated.

I don't remember its name but there is a guide on the iPhone Developer site from Apple that explains how to mix C++ and Objective-C with many examples. So you might want to check that out.
