But once you have that, the copy of the declaration elements and the count variable used to create it would be redundant, since you could just call IDirect3DVertexDeclaration9::GetDeclaration().
Something else, for the error handling for vertex/index buffer creation, just a "FAILED(hr)" and a WARN should do. ERR should imply a bug in either Wine or the underlying system, not just an application giving us crap, they do that all the time.
