16 The :mod:`dircache` module defines a function for reading directory listing
17 using a cache, and cache invalidation using the *mtime* of the directory.
18 Additionally, it defines a function to annotate directories by appending a

26 Resets the directory cache.
29 .. function:: listdir(path)
31 Return a directory listing of *path*, as gotten from :func:`os.listdir`. Note
32 that unless *path* changes, further call to :func:`listdir` will not re-read the
35 Note that the list returned should be regarded as read-only. (Perhaps a future
36 version should change it to return a tuple?)
39 .. function:: opendir(path)
41 Same as :func:`listdir`. Defined for backwards compatibility.
44 .. function:: annotate(head, list)
46 Assume *list* is a list of paths relative to *head*, and append, in place, a
47 ``'/'`` to each path which points to a directory.
