| '''Low-level interface to the Linux inotify subsystem. |
| |
| The inotify subsystem provides an efficient mechanism for file status |
| monitoring and change notification. |
| |
| This package provides the low-level inotify system call interface and |
| associated constants and helper functions. |
| |
| For a higher-level interface that remains highly efficient, use the |
| inotify.watcher package.''' |
