MIB_NOTIFICATION_TYPE enumeration (netioapi.h)

The MIB_NOTIFICATION_TYPE enumeration defines the notification type passed to a callback function when a notification occurs.

Syntax

typedef enum _MIB_NOTIFICATION_TYPE {
  MibParameterNotification,
  MibAddInstance,
  MibDeleteInstance,
  MibInitialNotification
} MIB_NOTIFICATION_TYPE, *PMIB_NOTIFICATION_TYPE;

Constants

MibParameterNotification A parameter was changed.
MibAddInstance A new MIB instance was added.
MibDeleteInstance An existing MIB instance was deleted.
MibInitialNotification A notification that is invoked immediately after registration for change notification completes. This initial notification does not indicate a change occurred to a MIB instance. The purpose of this initial notification type is to provide confirmation that the callback function is properly registered.

Remarks

The MIB_NOTIFICATION_TYPE enumeration is defined on Windows Vista and later.

On Windows Vista and later, new functions are provided to register to be notified when an IPv6 or IPv4 interface changes, a IPv6 or IPv4 unicast address changes, or an IPv6 or IPv4 route changes. These registration functions require a callback function be passed that is called when a change occurs. One of the parameters passed to the callback function when a notification occurs is a parameter containing a MIB_NOTIFICATION_TYPE that indicates the notification type.

Note that the Netioapi.h header file is automatically included in the Iphlpapi.h header file. The Netioapi.h header file should never be used directly.
