CUresult cuMemcpyDtoHAsync ( void *  dstHost, CUdeviceptr  srcDevice, size_t  ByteCount, CUstream  hStream   ) Copies from device to host memory. dstHost and srcDevice specify the base pointers of the destination and source, respectively. ByteCount specifies the number of bytes to copy. cuMemcpyDtoHAsync() is asynchronous and can optionally be associated to a stream by passing a non-zero hStream argument. It only works on page-locked memory and returns an error if a pointer to pageable memory is passed as input. Parameters: dstHost  - Destination host pointer srcDevice  - Source device pointer ByteCount  - Size of memory copy in bytes hStream  - Stream identifier Returns: CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUE Note: Note that this function may also return error codes from previous, asynchronous launches.
