Copies from one 1D CUDA array to host memory. dstHost specifies the base pointer of the destination. srcArray and srcOffset specify the CUDA array handle and starting offset in bytes of the source data. ByteCount specifies the number of bytes to copy.
- Parameters:
-
| dstHost | - Destination device pointer |
| srcArray | - Source array |
| srcOffset | - Offset in bytes of source array |
| ByteCount | - Size of memory copy in bytes |
- 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.
