Remarks
The CancelMibChangeNotify2 function deregisters a driver change notification previously requested for IP interface changes, IP address changes, or IP route changes on a local computer. These requests are made by calling NotifyIpInterfaceChange, NotifyRouteChange2, or NotifyUnicastIpAddressChange. The CancelMibChangeNotify2 function also cancels a previous request to retrieve the stable unicast IP address table on a local computer. This request is made by calling the NotifyStableUnicastIpAddressTable function.
The NotificationHandle parameter that is returned to these notification functions is passed to CancelMibChangeNotify2 to deregister driver change notifications or to cancel a pending request to retrieve the stable unicast IP address table.
