// The Darwin Notify Center is based on the <notify.h> API.

128
// (always "deliver immediately"). Other limitations in the <notify.h> API as described in
129

// - In the CFNotificationCallback, the 'object' and 'userInfo' parameters must be ignored.

// - CFNotificationCenterAddObserver(): the 'object' and 'suspensionBehavior' arguments are ignored.

// - CFNotificationCenterAddObserver(): the 'name' argument may not be NULL (for this center).

// The Darwin Notify Center has no notion of per-user sessions, all notifications are system-wide.

138
// common modes (usually kCFRunLoopDefaultMode) for Darwin-style notifications to be delivered.

// NOTE: NULL or 0 should be passed for all ignored arguments to ensure future compatibility.
