◆ handle_room_message()

void handle_room_message	(	struct GNUNET_MESSENGER_Room *	room,

		const struct GNUNET_MESSENGER_Message *	message,
		const struct GNUNET_HashCode *	hash,
		enum GNUNET_MESSENGER_MessageFlags	flags

Handles a message with a given hash in a room for the client API to update members and its information.

The function also stores the message in map locally for access afterwards.

The contact of the message's sender could be updated or even created. It may not be freed or destroyed though! (The contact may still be in use for old messages...)

Parameters

[in,out]	room	Room
[in,out]	sender	Contact of sender
[in]	message	Message
[in]	hash	Hash of message
[in]	flags	Flags of message
