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

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

Handles a sent key message to ensure changes to the public key of the sending handle.

Parameters

[in,out]	room	Room of the message
[in,out]	handle	Sending handle
[in]	message	KEY-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 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

		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
