cvbres_t GSNRegisterEvent	(	GSNODE	Node,
		TGSNodeEvent	EventID,

		size_t &	CallbackID
	)

Registers the given EventID on the given Node.

Attention

Parameters

[in]	Node	Node to register event on.
[in]	EventID	Event type to get notified on.
[in]	Callback	Callback function to call in case of EventID.
[in]	pPrivate	Pointer to private data given as the Callback function's parameter (e.g. pointer to a class).

GSNRegisterEventWithStatus()

cvbres_t GSNRegisterEventWithStatus	(	GSNODE	Node,
		TGSNodeEvent	EventID,
		TFGEVSrvStatus	Callback,
		void *	pPrivate,
		size_t &	CallbackID
	)

Registers the given EventID on the given Node.

The difference to the GSNRegisterEvent function is that the Callback has an additional argument which references a status. With that status a callee can communicate an error to the remote client for read/write access.

As there can be multiple registered callees, best check the status before doing your own processing. If a status other than CVC_ERROR(CVC_E_OK) is set after all callees finished their processing, the value in the node map is rolled back and an appropriate error acknowledge is sent.

Attention

Keep the Node handle alive as long as the event is needed as the Callback is stored in the handle and not in the Server Node.

Parameters

[in]	Node	Node to register event on.
[in]	EventID	Event type to get notified on.
[in]	Callback	Callback function to call in case of EventID.
[in]	pPrivate	Pointer to private data given as the Callback function's parameter (e.g. pointer to a class).
[out]	CallbackID	Node and EventID wide unique callback ID used to unregister the Callback.
