If I do not declare these functions, how do I call the Release method of
the appropriate interfaces?

Specifically, I started looking at the test for line.c - I believe that
if I create a mesh, I have to release it.

I have largely been learning from this page:
http://www.mvps.org/directx/articles/d3dxmesh.htm
(which is DirectX 8)
but it seems I have to somehow release the functions no?

Also, I'm probably going to start with the D3DXCreateBox function, as I
need to figure out exactly what's going on with the vertices before I
delve into something as complicated as spheres ;)

Thanks y'all :)

If it's just about releasing the interface, using the generic
IUnknown_Release macro should always work. The larger issue though is
that most (all?) of the d3dx9 interfaces don't have corresponding C
macros. That means you'll have to call those functions explicitly
through lpVtbl in C, but you'd have to do that when using the MS
headers as well.
