Variables Description
_data data The first int value of the list. ``_data'' is a union which actually contains a int value and a ``acl'' pointer. Usually, it is used to store the first item of a list. However, if an ``acl'' instance is deleted it is not actually removed but stored in a list of free ``acl'' instances. The ``acl'' pointer is used to maintain this list of unused ``acl'' instances.
