  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.
