Reclaiming Vertex Buffer memory
Author
Another noob directX question.
I am using directX 9.
Each object has a vertex buffer created using the CreateVertexBuffer method and then copying vertex information into it.
Everything works and it renders fine.
My question is, after I am done using the object (and the associated vertex buffer), I want to properly reclaim all
memory allocated to the object.
How do I reclaim the memory used by my vertexbuffer (LPDIRECT3DVERTEXBUFFER9)?
(is that what Release() does)
Thanks.

Thanks!
On a somewhat related topic, is there a similar method (is it FreePrivateData) to reclaim memory for a texture (IDirect3DTexture9 ) that is no longer in use.
Thanks again.

Use SAFE_RELEASE(object) macro to make sure that you are actually have a memory allocated before releasing. What it does is simply:
if(object) object->Release();
Ofcourse not all D3D objects have release methods so check beforehand.
if(object) object->Release();
Ofcourse not all D3D objects have release methods so check beforehand.

CComPtr<T> is a better choice.

There are some interfaces in the new Direct3D 10 effect framework that are not derives from IUnknown.
