This message is an ao2 object, and must be ao2_cleanup()'ed when you are done with it. Messages are also immutable, and must not be modified after they are initialized. Especially the data in the message.

Parameters

type	Type of the message
data	Immutable data that is the actual contents of the message

Returns

New message

stasis_message_create_full()

struct stasis_message* stasis_message_create_full	(	struct stasis_message_type *	type,
		void *	data,
		const struct ast_eid *	eid
	)

Create a new message for an entity.

This message is an ao2 object, and must be ao2_cleanup()'ed when you are done with it. Messages are also immutable, and must not be modified after they are initialized. Especially the data in the message.

Parameters

type	Type of the message
data	Immutable data that is the actual contents of the message
eid	What entity originated this message. (NULL for aggregate)

Note

An aggregate message is a combined representation of the local and remote entities publishing the message data. e.g., An aggregate device state represents the combined device state from the local and any remote entities publishing state for a device. e.g., An aggregate MWI message is the old/new MWI counts accumulated from the local and any remote entities publishing to a mailbox.

Return values

New	message
