		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
	)

(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
