Method

GckObjectcache_lookup

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.

Parameters

`attr_types`	An array of `gulong`
	The types of attributes to update.
	The length of the array is specified in the `n_attr_types` argument.
	The data is owned by the caller of the function.
`n_attr_types`	`gint`
	The number of attribute types.
`cancellable`	`GCancellable`
	Optional cancellation object.
	The argument can be `NULL`.
	The data is owned by the caller of the function.
`error`	`GError **`
	The return location for a `GError*`, or `NULL`.

Return value

Returns:	`GckAttributes`
	The attributes retrieved or `NULL` on failure.
	The caller of the method takes ownership of the data, and is responsible for freeing it.
