cudaError_t cudaD3D11GetDevices ( unsigned int *  pCudaDeviceCount, int *  pCudaDevices, unsigned int  cudaDeviceCount, ID3D11Device *  pD3D11Device, enum cudaD3D11DeviceList  deviceList   ) Returns in *pCudaDeviceCount the number of CUDA-compatible devices corresponding to the Direct3D 11 device pD3D11Device. Also returns in *pCudaDevices at most cudaDeviceCount of the the CUDA-compatible devices corresponding to the Direct3D 11 device pD3D11Device. If any of the GPUs being used to render pDevice are not CUDA capable then the call will return cudaErrorNoDevice. Parameters: pCudaDeviceCount  - Returned number of CUDA devices corresponding to pD3D11Device pCudaDevices  - Returned CUDA devices corresponding to pD3D11Device cudaDeviceCount  - The size of the output device array pCudaDevices pD3D11Device  - Direct3D 11 device to query for CUDA devices deviceList  - The set of devices to return. This set may be cudaD3D11DeviceListAll for all devices, cudaD3D11DeviceListCurrentFrame for the devices used to render the current frame (in SLI), or cudaD3D11DeviceListNextFrame for the devices used to render the next frame (in SLI). Returns: cudaSuccess, cudaErrorNoDevice, cudaErrorUnknown Note: Note that this function may also return error codes from previous, asynchronous launches.
