◆ next

struct CadetReliableMessage* CadetReliableMessage::next

Double linked list, FIFO style.

◆ prev

struct CadetReliableMessage* CadetReliableMessage::prev

◆ ch

struct CadetChannel* CadetReliableMessage::ch

◆ qe

struct CadetTunnelQueueEntry* CadetReliableMessage::qe

◆ first_transmission_time

struct GNUNET_TIME_Absolute CadetReliableMessage::first_transmission_time

Time when we first successfully transmitted the message (that is, set num_transmissions to 1).

Referenced by data_sent_cb(), and handle_matching_ack().

◆ connection_taken

struct GNUNET_CADET_ConnectionTunnelIdentifier CadetReliableMessage::connection_taken

Identifier of the connection that this message took when it was first transmitted.

Only useful if num_transmissions is 1.

Definition at line 162 of file gnunet-service-cadet_channel.c.

Referenced by data_sent_cb(), and handle_matching_ack().

◆ num_transmissions

int CadetReliableMessage::num_transmissions

How often was this message transmitted? GNUNET_SYSERR if there was an error transmitting the message, GNUNET_NO if it was not yet transmitted ever, otherwise the number of (re) transmissions.
