- /* An MRU is a list that cannot hold more than a certain number of */
- /* elements (`max_elements'). All elements in the list are sorted in */
- /* least-recently-used order, i.e., the `oldest' element is at the tail */
- /* of the list. */
- /* */
- /* When doing a lookup (either through `Lookup()' or `Lookup_Node()'), */
- /* the list is searched for an element with the corresponding key. If */
- /* it is found, the element is moved to the head of the list and is */
- /* returned. */
- /* */
- /* If no corresponding element is found, the lookup routine will try to */
- /* obtain a new element with the relevant key. If the list is already */
- /* full, the oldest element from the list is discarded and replaced by a */
- /* new one; a new element is added to the list otherwise. */
- /* */
- /* Note that it is possible to pre-allocate the element list nodes. */
- /* This is handy if `max_elements' is sufficiently small, as it saves */
- /* allocations/releases during the lookup process. */
