Walks the specified root path for all files and matches them to this
path-spec.
*root* (:class:`str`) is the root directory to search for files.
*on_error* (:class:`~collections.abc.Callable` or :data:`None`)
optionally is the error handler for file-system exceptions. See

*follow_links* (:class:`bool` or :data:`None`) optionally is whether
to walk symbolic links that resolve to directories. See

Returns the matched files (:class:`~collections.abc.Iterable` of
