◆ core_startup_cb()

static void core_startup_cb ( void *  cls,
const struct GNUNET_PeerIdentity my_identity 
)
static

Function called after GNUNET_CORE_connect() has succeeded (or failed for good).

Note that the private key of the peer is intentionally not exposed here; if you need it, your process should try to read the private key file directly (which should work if you are authorized...). Implementations of this function must not call GNUNET_CORE_disconnect() (other than by scheduling a new task to do this later).

Parameters
clsthe PooledConnection object
my_identityID of this peer, NULL if we failed

void *  cb_cls,
const struct GNUNET_PeerIdentity target,
GST_connection_pool_peer_connect_notify  connect_notify_cb,
void *  connect_notify_cb_cls 
)

Get a connection handle to service.

If the connection is opened before and the connection handle is present in the connection pool, it is returned through cb. peer_id is used for the lookup in the connection pool. If the connection handle is not present in the connection pool, a new connection handle is opened for the service using cfg. Additionally, target, connect_notify_cb can be specified to get notified when target is connected at service.

Note
connect_notify_cb will not be called if target is already connected service level. Use GNUNET_TRANSPORT_check_peer_connected() or a similar function from the respective service's API to check if the target peer is already connected or not. connect_notify_cb will be called only once or never (in case target cannot be connected or is already connected).
Parameters
peer_idthe index of the peer
cfgthe configuration with which the transport handle has to be created if it was not present in the cache
servicethe service of interest
cbthe callback to notify when the transport handle is available
cb_clsthe closure for cb
targetthe peer identify of the peer whose connection to our TRANSPORT subsystem will be notified through the connect_notify_cb. Can be NULL
connect_notify_cbthe callback to call when the target peer is connected. This callback will only be called once or never again (in case the target peer cannot be connected). Can be NULL
connect_notify_cb_clsthe closure for connect_notify_cb
Returns

◆ GST_connection_pool_get_handle_done()

void GST_connection_pool_get_handle_done ( struct GST_ConnectionPool_GetHandle gh)

Relinquish a GST_ConnectionPool_GetHandle object.

If the connection associated with the object is currently being used by other GST_ConnectionPool_GetHandle objects, it is left in the connection pool. If no other objects are using the connection and the connection pool is not full then it is placed in a LRU queue. If the connection pool is full, then connections from the LRU queue are evicted and closed to create place for this connection. If the connection pool if full and the LRU queue is empty, then the connection is closed.
