It only works on page-locked memory and returns an error if a pointer to pageable memory is passed asinput.Parameters:dptr - Destination device pointersrc - Source host pointerbytes - Size of memory copy in byteshStream - Stream identifierReturns:Note:CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_-ERROR_INVALID_CONTEXT, CUDA_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, cuMemcpyDtoA, cuMemcpyDtoD, cuMemcpyDtoH, cuMemcpyDtoHAsync, cuMemcpyHtoA,cuMemcpyHtoAAsync, cuMemcpyHtoD, cuMemFree, cuMemFreeHost, cuMemGetAddressRange, cuMemGet-Info, cuMemHostAlloc, cuMemHostGetDevicePointer, cuMemsetD2D8, cuMemsetD2D16, cuMemsetD2D32,cuMemsetD8, cuMemsetD16, cuMemsetD323.25.2.26 CUresult cuMemFree (CUdeviceptr dptr)Frees the memory space pointed to by dptr, which must have been returned by a previous call to cuMemAlloc() orcuMemAllocPitch().Generated on Wed Apr 1 16:11:42 2009 for NVIDIA CUDA Library by Doxygen
