Function Documentation

◆ attribute()

struct pq_array_header __attribute__ ( (packed) )

◆ GNUNET_PQ_event_reconnect_()

void GNUNET_PQ_event_reconnect_	(	struct GNUNET_PQ_Context *	db,
		int	fd
	)

Internal API.

Reconnect should re-register notifications after a disconnect.

Parameters

db	the DB handle
fd	socket to listen on
