Function Documentation

send_message_join()

void send_message_join	(	struct GNUNET_MESSENGER_SrvRoom *	room,
		struct GNUNET_MESSENGER_SrvHandle *	handle,
		const struct GNUNET_MESSENGER_Message *	message,
		const struct GNUNET_HashCode *	hash
	)

Handles a sent join message to ensure growth of the decentralized room structure.

(if the service provides a peer message for this room currently, it will be forwarded)

Parameters

	[in/out]	room Room of the message
	[in/out]	handle Sending handle
[in]	message	JOIN-Message
[in]	hash	Hash of the message

send_message_peer()

void send_message_peer	(	struct GNUNET_MESSENGER_SrvRoom *	room,
		struct GNUNET_MESSENGER_SrvHandle *	handle,
		const struct GNUNET_MESSENGER_Message *	message,
		const struct GNUNET_HashCode *	hash
	)

Handles a sent peer message to update the rooms peer message of this service.

(a set peer message indicates this service being a part of the decentralized room structure)

Parameters

	[in/out]	room Room of the message
	[in/out]	handle Sending handle
[in]	message	PEER-Message
[in]	hash	Hash of the message

send_message_id()

void send_message_id	(	struct GNUNET_MESSENGER_SrvRoom *	room,
		struct GNUNET_MESSENGER_SrvHandle *	handle,
		const struct GNUNET_MESSENGER_Message *	message,
		const struct GNUNET_HashCode *	hash
	)

Handles a sent id message to update the handles member id in the room.

(changing member id is useful to prevent collisions)

Parameters

	[in/out]	room Room of the message
	[in/out]	handle Sending handle
[in]	message	ID-Message
[in]	hash	Hash of the message

		struct GNUNET_MESSENGER_SrvHandle *	handle,
		const struct GNUNET_MESSENGER_Message *	message,
		const struct GNUNET_HashCode *	hash
	)

Handles a sent request message to trigger the request operation for this service.

(the request operation will deactivate the possibility of spamming requests)

Parameters

	[in/out]	room Room of the message
	[in/out]	handle Sending handle
[in]	message	PEER-Message
[in]	hash	Hash of the message
