atcache(3)
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.
