header

struct GNUNET_MessageHeader TransportFragmentBoxMessage::header

Type is GNUNET_MESSAGE_TYPE_TRANSPORT_FRAGMENT.

Definition at line 532 of file gnunet-service-transport.c.

Referenced by check_fragment_box(), fragment_message(), and handle_fragment_box().

frag_off

uint16_t TransportFragmentBoxMessage::frag_off

Offset of this fragment in the overall message.

Definition at line 537 of file gnunet-service-transport.c.

Referenced by check_fragment_box(), fragment_message(), and handle_fragment_box().

msg_size

uint16_t TransportFragmentBoxMessage::msg_size

Total size of the message that is being fragmented.

Definition at line 542 of file gnunet-service-transport.c.

Referenced by check_fragment_box(), fragment_message(), and handle_fragment_box().

ack_uuid

struct AcknowledgementUUIDP TransportFragmentBoxMessage::ack_uuid

Unique ID of this fragment (and fragment transmission!).

Will change even if a fragment is retransmitted to make each transmission attempt unique! If a client receives a duplicate fragment (same frag_off for same msg_uuid, it must send GNUNET_MESSAGE_TYPE_TRANSPORT_RELIABILITY_ACK immediately.

Referenced by fragment_message(), and handle_fragment_box().

msg_uuid

struct MessageUUIDP TransportFragmentBoxMessage::msg_uuid

Original message ID for of the message that all the fragments belong to.

Must be the same for all fragments.

Definition at line 557 of file gnunet-service-transport.c.
