CancelIPChangeNotify function

The CancelIPChangeNotify function cancels notification of IPv4 address and route changes previously requested with successful calls to the NotifyAddrChange or NotifyRouteChange functions.

  _In_  LPOVERLAPPED notifyOverlapped
);

Parameters

notifyOverlapped [in]

A pointer to the OVERLAPPED structure used in the previous call to NotifyAddrChange or NotifyRouteChange.

Remarks

The CancelIPChangeNotify function deregisters for a change notification previously requested for IPv4 address or route changes on a local computer. These requests to register for notification are made by calling the NotifyAddrChange or NotifyRouteChange functions.

The OVERLAPPED structure used in the previous call to one of these notification functions is passed to CancelIPChangeNotify function in the notifyOverlapped parameter to deregister for notifications.

The CancelIPChangeNotify can return FALSE if no notification request was found or an invalid notifyOverlapped parameter was passed.
