◆ dht_connect_adapter()

static void* dht_connect_adapter ( void *  cls,
const struct GNUNET_CONFIGURATION_Handle cfg 
)
static

Adapter function called to establish a connection to the DHT service.

Parameters

cfgconfiguration of the peer to connect to; will be available until GNUNET_TESTBED_operation_done() is called on the operation returned from GNUNET_TESTBED_service_connect()
Returns
service handle to return in 'op_result', NULL on error
