492 * Instead of a ldbm-style dn2id database, we use a hierarchical one. Each
493 * entry in this database is a struct diskNode, keyed by entryID and with
494 * the data containing the RDN and entryID of the node's children. We use
495 * a B-Tree with sorted duplicates to store all the children of a node under
496 * the same key. Also, the first item under the key contains the entry's own
497 * rdn and the ID of the node's parent, to allow bottom-up tree traversal as
498 * well as top-down. To keep this info first in the list, the nrdnlen is set
499 * to the negative of its value.
501 * The diskNode is a variable length structure. This definition is not
502 * directly usable for in-memory manipulation.
