WNV_OBJECT_CHANGE_PARAM structure (wnvapi.h)

Specifies the parameters of an event that causes the Windows Network Virtualization (WNV) driver to generate a WnvObjectChangeType type of notification. If there is a pending call to the WnvRequestNotification function of this type, the WNV driver fills the buffer that is passed in the NotificationParam argument's WNV_NOTIFICATION_PARAM structure with one or more instances of this structure and completes the WnvRequestNotification function call.

Syntax

typedef struct _WNV_OBJECT_CHANGE_PARAM {
  WNV_OBJECT_TYPE ObjectType;
  union {
    WNV_PROVIDER_ADDRESS_CHANGE_PARAM ProviderAddressChange;
    WNV_CUSTOMER_ADDRESS_CHANGE_PARAM CustomerAddressChange;
  } ObjectParam;
} WNV_OBJECT_CHANGE_PARAM, *PWNV_OBJECT_CHANGE_PARAM;
