Description

A GckEnumerator can be used to enumerate through PKCS#11 objects. It will automatically create sessions as necessary.

Use gck_modules_enumerate_objects() or gck_modules_enumerate_uri() to create an enumerator. To get the objects use gck_enumerator_next() or gck_enumerator_next_async() functions.

Details

struct GckEnumerator

struct GckEnumerator;

An object that allows enumerating of objects across modules, tokens.

gck_enumerator_next ()

GckObject *         gck_enumerator_next                 (GckEnumerator *self,
                                                         GCancellable *cancellable,
                                                         GError **error);

Get the next object in the enumerator, or NULL if there are no more objects.

NULL is also returned if the function fails. Use the error to determine whether a failure occurred or not.

self :

 The enumerator

cancellable :

 A GCancellable or NULL

error :

 A location to store an error on failure

Returns :

 The next object, which must be released using g_object_unref, or NULL. [transfer full][allow-none]

gck_enumerator_next_async ()

callback :

 Called when the result is ready

user_data :

Complete an operation to enumerate next objects.

NULL is also returned if the function fails. Use the error to determine whether a failure occurred or not.

self :

 An enumerator

result :

 The result passed to the callback

error :

 A location to raise an error on failure.

Returns :

 The list of objects, which should be freed with gck_list_unref_free(). [element-type Gck.Module][transfer full]

gck_enumerator_next_n ()

GList *             gck_enumerator_next_n               (GckEnumerator *self,

Get the next set of objects from the enumerator. The maximum number of objects can be specified with max_objects. If -1 is specified, then all the remaining objects will be returned.

NULL is also returned if the function fails. Use the error to determine whether a failure occurred or not.

self :

 An enumerator

max_objects :

 The maximum amount of objects to enumerate

cancellable :

 A GCancellable or NULL

error :

 A location to store an error on failure

Set the type of objects to be created by this enumerator. The type must always be either GckObject or derived from it.

If the GckObjectCache interface is implemented on the derived class and the attribute_types field is set, then the enumerator will retrieve attributes for each object.
