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

Type: 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 method.
n_attr_types

Type: gint

The number of attribute types.

cancellable

Type: GCancellable

Optional cancellation object.

The argument can be NULL.
The data is owned by the caller of the method.
error

Type: GError **

The return location for a recoverable error.

The argument can be NULL.
If the return location is not NULL, then you must initialize it to a NULL GError*.
The argument will be left initialized to NULL by the method if there are no errors.
In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.

Return value

Type: GckAttributes

The attributes retrieved or NULL on failure.

The caller of the method takes ownership of the returned data, and is responsible for freeing it.
