Declaration

func CFNotificationCenterPostNotificationWithOptions(_ center: CFNotificationCenter!, _ name: CFNotificationName!, _ object: UnsafeRawPointer!, _ userInfo: CFDictionary!, _ options: CFOptionFlags)

Parameters

• center:

  The notification center to post the notification.

• name:

  The name of the notification to post. This value must not be NULL.

• object:

  The object posting the notification. If NULL, the notification is sent only to observers that are observing all objects. In other words, only observers that registered for the notification with a NULL value for object will receive the notification.

  If you want to allow your clients to register for notifications using Cocoa APIs (see Notificationcenter), then object must be a Core Foundation or Cocoa object.

  For distributed notifications, object must be a CFString object.

  If center is a Darwin notification center, this value is ignored.

• userInfo:

  A dictionary to pass to observers. You populate this dictionary with additional information describing the notification. For distributed notifications, the dictionary must contain only property list objects. Can be NULL. If center is a Darwin notification center, this value is ignored.

• options:

  Specifies if the notification should be posted immediately, or to all sessions. See 1569610 Notification Posting Options for possible values.

  If center is a Darwin notification center, this value is ignored.
