Definition: gnunet-search.c:97
int GNUNET_CONTAINER_multishortmap_iterate(struct GNUNET_CONTAINER_MultiShortmap *map, GNUNET_CONTAINER_ShortmapIterator it, void *it_cls)
Iterate over all entries in the map.
#define GNUNET_log(kind,...)
static enum GNUNET_GenericReturnValue register_notify(void *cls, const struct GNUNET_ShortHashCode *sh, void *value)
Re-subscribe to notifications after disconnect.
Definition: pq_event.c:397
static void scheduler_fd_cb(void *cls, int fd)
Function called when the Postgres FD changes and we need to update the scheduler event loop task.
