150 Module Documentation3.25.2.18 CUresult cuMemcpyDtoA (CUarray hDst, unsigned int DstOffset, CUdeviceptr dptr, unsigned intNumBytes)Copies from device memory to a 1D <strong>CUDA</strong> array. hDst and DstOffset specify the <strong>CUDA</strong> array handle andstarting index of the destination data. dptr specifies the base pointer of the source. NumBytes specifies the numberof bytes to copy.Parameters:hDst - Destination arrayDstOffset - Offset of destination arraydptr - Source device pointerNumBytes - Size of memory copy in bytesReturns:Note:<strong>CUDA</strong>_SUCCESS, <strong>CUDA</strong>_ERROR_DEINITIALIZED, <strong>CUDA</strong>_ERROR_NOT_INITIALIZED, <strong>CUDA</strong>_-ERROR_INVALID_CONTEXT, <strong>CUDA</strong>_ERROR_INVALID_VALUESee also:Note that this function may also return error codes from previous, asynchronous launches.cuArray3DCreate, cuArray3DGetDescriptor, cuArrayCreate, cuArrayDestroy, cuArrayGetDescriptor, cuMemAlloc,cuMemAllocHost, cuMemAllocPitch, cuMemcpy2D, cuMemcpy2DAsync, cuMemcpy2DUnaligned,cuMemcpy3D, cuMemcpy3DAsync, cuMemcpyAtoA, cuMemcpyAtoD, cuMemcpyAtoH, cuMemcpyAto-HAsync, cuMemcpyDtoD, cuMemcpyDtoH, cuMemcpyDtoHAsync, cuMemcpyHtoA, cuMemcpyHtoAAsync,cuMemcpyHtoD, cuMemcpyHtoDAsync, cuMemFree, cuMemFreeHost, cuMemGetAddressRange, cuMemGet-Info, cuMemHostAlloc, cuMemHostGetDevicePointer, cuMemsetD2D8, cuMemsetD2D16, cuMemsetD2D32,cuMemsetD8, cuMemsetD16, cuMemsetD323.25.2.19 CUresult cuMemcpyDtoD (CUdeviceptr dst, CUdeviceptr src, unsigned int bytes)Copies from device memory to device memory. dst and src are the base pointers of the destination and source,respectively. bytes specifies the number of bytes to copy.
