Declaration [src]
GckAttributes*
gck_object_cache_lookup (
  GckObject* object,
  const gulong* attr_types,
  gint n_attr_types,
  GCancellable* cancellable,
  GError** error
)
Description [src]
Lookup attributes in the cache, or retrieve them from the object if necessary.
If object is a GckObjectCache then this will lookup the attributes there
first if available, otherwise will read them from the object and update
the cache.
If object is not a GckObjectCache, then the attributes will simply be
read from the object.
This may block, use the asynchronous version when this is not desirable.
