CUresult cuMemcpyHtoAAsync ( CUarray  hDst,
unsigned int  dstOffset,
const void *  pSrc,
unsigned int  bytes,
CUstream  hStream 
)

Copies from host memory to a 1D CUDA array. hDst and dstOffset specify the CUDA array handle and starting index of the destination data. pSrc specifies the base address of the source. bytes specifies the number of bytes to copy.

cuMemcpyHtoAAsync() 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:
hDst - Destination array
dstOffset - Offset of destination array
pSrc - Source host pointer
bytes - 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.
