Passes back the device pointer pdptr corresponding to the mapped, pinned host buffer p allocated by cuMemHostAlloc.
cuMemHostGetDevicePointer() will fail if the CU_MEMALLOCHOST_DEVICEMAP flag was not specified at the time the memory was allocated, or if the function is called on a GPU that does not support mapped pinned memory.
Flags provides for future releases. For now, it must be set to 0.
- Parameters:
-
| pdptr | - Returned device pointer |
| p | - Host pointer |
| Flags | - Options (must be 0) |
- 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.
