Definition: gnunet-rps.c:41
void RPS_sampler_update(struct RPS_Sampler *sampler, const struct GNUNET_PeerIdentity *id)
Update every sampler element of this sampler with given peer.
struct RPS_Sampler * RPS_sampler_init(size_t init_size, struct GNUNET_TIME_Relative max_round_interval)
Initialise a tuple of samplers.
void RPS_sampler_reinitialise_by_value(struct RPS_Sampler *sampler, const struct GNUNET_PeerIdentity *id)
Reinitialise all previously initialised sampler elements with the given value.
void RPS_sampler_resize(struct RPS_Sampler *sampler, unsigned int new_size)
Grow or shrink the size of the sampler.
void RPS_sampler_request_cancel(struct RPS_SamplerRequestHandle *req_handle)
Cancel a request issued through RPS_sampler_n_rand_peers_ready_cb.
void RPS_sampler_destroy(struct RPS_Sampler *sampler)
Cleans the samplers.
unsigned int RPS_sampler_get_size(struct RPS_Sampler *sampler)
Get the size of the sampler.
