Notification hub for the application.
public class CFNotificationCenter : CoreFoundation.NativeObjecttype CFNotificationCenter = class
inherit NativeObject- Inheritance
Remarks
The CFNotificationCenter is a hub that is used to listen to broadcast messages and post broadcast messages in an application. The messages that are posted are synchronous.
Posting a notification is a synchronous process, which means that invoking one of the Post messages on the notification center will block execution until all of the notification handlers have completed running.
While the NSNotificationCenter also provides a notification hub, they are separate from each other. The CFNotificationCenter provides three hubs: an application local hub, the Darwin hub (for OS-global notifications) and a distributed hub (only available on Mac).
