* @name IDirect3DDevice9::GetBackBuffer
* @implemented
*
* The function IDirect3DDevice9Base_GetBackBuffer retrieves the back buffer
* for the specified swap chain.
*
* @param LPDIRECT3D iface
* Pointer to the IDirect3DDevice9 object returned from IDirect3D9::CreateDevice().
*
* @param UINT iSwapChain
* Swap chain index to get object for.
* The maximum value for this is the value returned by IDirect3DDevice9::GetNumberOfSwapChains() - 1.
*
* @param UINT iBackBuffer
* Back buffer index to get object for.
* The maximum value for this is the the total number of back buffers - 1, as indexing starts at 0.
*
* @param IDirect3DSurface9** ppBackBuffer
* Pointer to a IDirect3DSurface9* to receive the back buffer object
*
* @return HRESULT
* If the method successfully sets the ppBackBuffer pointer, the return value is D3D_OK.
* If iSwapChain or iBackBuffer is out of range, Type is invalid or ppBackBuffer is a bad pointer,
* the return value will be D3DERR_INVALIDCALL.
