| 981 | * |
| 982 | * More sophisticated management can be enabled by the provision of a |
| 983 | * strategy routine with the table entry. This will be called before |
| 984 | * any automatic read or write of the data is performed. |
| 985 | * |
| 986 | * The strategy routine may return: |
| 987 | * <0: Error occurred (error is passed to user process) |
| 988 | * 0: OK - proceed with automatic read or write. |
| 989 | * >0: OK - read or write has been done by the strategy routine, so |
| 990 | * return immediately. |
