'''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.'''
