Data Structures
struct	SubscriberList
	Lists of subscribers we manage for notifications. More...
struct	GNUNET_NotificationContext
	The notification context is the key datastructure for a convenience API used for transmission of notifications to the subscriber until the subscriber disconnects (or the notification context is destroyed, in which case we disconnect these subscribers). More...

Macros
#define	LOG(kind, ...)   GNUNET_log_from (kind, "util-nc", __VA_ARGS__)

Functions
static void	handle_mq_destroy (void *cls)
	Subscriber has disconnected, clean up.
struct GNUNET_NotificationContext *	GNUNET_notification_context_create (unsigned int queue_length)
	Create a new notification context.
void	GNUNET_notification_context_destroy (struct GNUNET_NotificationContext *nc)
	Destroy the context, force disconnect for all subscribers.
void	GNUNET_notification_context_add (struct GNUNET_NotificationContext *nc, struct GNUNET_MQ_Handle *mq)
	Add a subscriber to the notification context.
void	GNUNET_notification_context_broadcast (struct GNUNET_NotificationContext *nc, const struct GNUNET_MessageHeader *msg, int can_drop)
	Send a message to all subscribers of this context.
unsigned int	GNUNET_notification_context_get_size (struct GNUNET_NotificationContext *nc)
	Return active number of subscribers in this context.
