	)

List all attributes for a local identity.

This MUST lock the struct GNUNET_RECLAIM_Handle for any other calls than GNUNET_RECLAIM_get_attributes_next() and GNUNET_RECLAIM_get_attributes_stop. proc will be called once immediately, and then again after GNUNET_RECLAIM_get_attributes_next() is invoked.

On error (disconnect), error_cb will be invoked. On normal completion, finish_cb proc will be invoked.

Parameters

h	Handle to the re:claimID service
identity	Identity to iterate over
error_cb	Function to call on error (i.e. disconnect), the handle is afterwards invalid
error_cb_cls	Closure for error_cb
proc	Function to call on each attribute
proc_cls	Closure for proc
finish_cb	Function to call on completion the handle is afterwards invalid
finish_cb_cls	Closure for finish_cb

Returns

an iterator Handle to use for iteration

GNUNET_RECLAIM_ticket_iteration_start()

struct GNUNET_RECLAIM_TicketIterator* GNUNET_RECLAIM_ticket_iteration_start	(	struct GNUNET_RECLAIM_Handle *	h,

		GNUNET_RECLAIM_TicketCallback	proc,
		void *	proc_cls,
		GNUNET_SCHEDULER_TaskCallback	finish_cb,
		void *	finish_cb_cls
	)

Lists all tickets that have been issued to remote identites (relying parties)

Parameters

h	the identity provider to use
identity	the issuing identity
error_cb	function to call on error (i.e. disconnect), the handle is afterwards invalid
error_cb_cls	closure for error_cb
proc	function to call on each ticket; it will be called repeatedly with a value (if available)
proc_cls	closure for proc
finish_cb	function to call on completion the handle is afterwards invalid
finish_cb_cls	closure for finish_cb

Returns

an iterator handle to use for iteration

Parameters

h	the reclaim to use
identity	the issuing identity
error_cb	function to call on error (i.e. disconnect), the handle is afterwards invalid

void GNUNET_RECLAIM_cancel

(

struct GNUNET_RECLAIM_Operation *

Cancel an identity provider operation.

Note that the operation MAY still be executed; this merely cancels the continuation; if the request was already transmitted, the service may still choose to complete the operation.

Parameters

op	operation to cancel

Cancel an identity provider operation.

Note that the operation MAY still be executed; this merely cancels the continuation; if the request was already transmitted, the service may still choose to complete the operation.

Parameters

op	operation to cancel
