cudaError_t cudaD3D9SetDirect3DDevice ( IDirect3DDevice9 *  pD3D9Device  ) 

Records pD3D9Device as the Direct3D device to use for Direct3D interoperability on this host thread. If the host thread has already initialized the CUDA runtime by calling non-device management runtime functions or if there exists a CUDA driver context active on the host thread, then this call returns cudaErrorSetOnActiveProcess.

Successful context creation on pD3D9Device will increase the internal reference count on pD3D9Device. This reference count will be decremented upon destruction of this context through cudaThreadExit().

Parameters:
pD3D9Device - Direct3D device to use for this thread
Returns:
cudaSuccess, cudaErrorInitializationError, cudaErrorInvalidValue, cudaErrorSetOnActiveProcess
Note:
Note that this function may also return error codes from previous, asynchronous launches.
