Get the constant buffers used by the domain-shader stage.
void DSGetConstantBuffers( UINT StartSlot, UINT NumBuffers, ID3D11Buffer **ppConstantBuffers );
Index into the device's zero-based array to begin retrieving constant buffers from (ranges from 0 to D3D11_COMMONSHADER_CONSTANT_BUFFER_API_SLOT_COUNT - 1).
Number of buffers to retrieve (ranges from 0 to D3D11_COMMONSHADER_CONSTANT_BUFFER_API_SLOT_COUNT - StartSlot).
Array of constant buffer interface pointers (see ID3D11Buffer) to be returned by the method.
Any returned interfaces will have their reference count incremented by one. Applications should call IUnknown::Release on the returned interfaces when they are no longer needed to avoid memory leaks.
