NAME

       atSaveCache, atCacheKey - derived object cache handling

SYNOPSIS

       #include <atfs.h>
       #include <atfstk.h>

       int  atSaveCache (Af_key *aso, Af_key *cachedAso, char *uniqAttribute, int storeType);

       char*atCacheKey (Af_key *aso);

DESCRIPTION

       atSaveCache  adds  the  given busy object aso to the current derived object cache. It does
       this by calling  af_savecache  (manual  page  af_cache(3)).  Prior  to  that,  atSaveCache
       attaches  a key attribute with the name __CacheKey__ to aso, by which the resulting cached
       object can be uniquely identified within the cache. Return values are  the  same  as  from
       af_savecache (manual page af_cache(3)).

       atCacheKey  returns  an attribute string consisting of the attribute name __CacheKey__ and
       an attribute value built of the aso modification date,  the  process  number  and  a  (per
       process  unique) serial number. This attribute can (and will) be used to uniquely identify
       attributed software objects in derived object caches.
