10 * This file contains FPCatSearch implementation. FPCatSearch performs
11 * file/directory search based on specified criteria. It is used by client
12 * to perform fast searches on (propably) big volumes. So, it has to be
15 * This implementation bypasses most of adouble/libatalk stuff as long as
16 * possible and does a standard filesystem search. It calls higher-level
17 * libatalk/afpd functions only when it is really needed, mainly while
18 * returning some non-UNIX information or filtering by non-UNIX criteria.
20 * Initial version written by Rafal Lewczuk <rlewczuk@pronet.pl>
22 * Starting with Netatalk 2.2 searching by name criteria utilizes the
23 * CNID database in conjunction with an enhanced cnid_dbd. This requires
24 * the use of cnidscheme:dbd for the searched volume, the new functionality
25 * is not built into cnidscheme:cdb.
