void GCPP_try_path_from_dht(const struct GNUNET_DHT_PathElement *get_path, unsigned int get_path_length, const struct GNUNET_DHT_PathElement *put_path, unsigned int put_path_length)
Create a peer path based on the result of a DHT lookup.
struct CadetPeer * GCPP_get_peer_at_offset(struct CadetPeerPath *path, unsigned int off)
Obtain the peer at offset off in path.
unsigned int GCPP_get_length(struct CadetPeerPath *path)
Return the length of the path.
struct CadetPeerPath * GCPP_get_path_from_route(unsigned int path_length, const struct GNUNET_PeerIdentity *pids)
We got an incoming connection, obtain the corresponding path.
GNUNET_CONTAINER_HeapCostType GCPP_get_desirability(const struct CadetPeerPath *path)
Return how much we like keeping the path.
const char * GCPP_2s(struct CadetPeerPath *p)
Convert a path to a human-readable string.
struct CadetConnection * GCPP_get_connection(struct CadetPeerPath *path, struct CadetPeer *destination, unsigned int off)
Return connection to destination using path, or return NULL if no such connection exists.
void GCPP_del_connection(struct CadetPeerPath *path, unsigned int off, struct CadetConnection *cc)
Notify path that it is no longer used for connection cc which ended at the path's offset off.
void GCPP_release(struct CadetPeerPath *path)
The given peer cp used to own this path.
void GCPP_add_connection(struct CadetPeerPath *path, unsigned int off, struct CadetConnection *cc)
Notify path that it is used for connection cc which ends at the path's offset off.
unsigned int GCPP_find_peer(struct CadetPeerPath *path, struct CadetPeer *cp)
Find peer's offset on path.
static struct GNUNET_OS_Process * p
Helper process we started.
Definition: gnunet-uri.c:37
API to the DHT service.
uint64_t GNUNET_CONTAINER_HeapCostType
Cost by which elements in a heap can be ordered.
Low-level connection to a destination.
struct CadetPeerPath * path
Path we are using to our destination.
unsigned int off
Offset of our destination in path.
struct CadetPeer * destination
To which peer does this connection go?
Information regarding a possible path to reach a peer.
Peer description.
A (signed) path tracking a block's flow through the DHT is represented by an array of path elements,...
The identity of the host (wraps the signing key of the peer).
