# Data Structures

`llfuse.``ENOATTR`

  This errorcode is unfortunately missing in the `errno` module, so it is provided by Python-LLFUSE instead.

`llfuse.``ROOT_INODE`

  The inode of the root directory, i.e. the mount point of the file system.

`llfuse.``default_options`

  This is a recommended set of options that should be passed to `llfuse.init` to get reasonable behavior and performance. Python-LLFUSE is compatible with any other combination of options as well, but you should only deviate from the defaults with good reason.

  (The `fsname=<foo>` option is guaranteed never to be included in the default options, so you can always safely add it to the set).

  New in version 0.42.
