Returns the base address in *pbase and size in *psize of the allocation by cuMemAlloc() or cuMemAllocPitch() that contains the input pointer dptr . Both parameters pbase and psize are optional. If one of them is NULL, it is ignored.
- Parameters:
-
| pbase | - Returned base address |
| psize | - Returned size of device memory allocation |
| dptr | - Device pointer to query |
- 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.
