NDIS_WMI_EVENT_HEADER structure (ntddndis.h)

The NDIS_WMI_EVENT_HEADER structure provides information about a GUID event for WMI clients.

Syntax

typedef struct _NDIS_WMI_EVENT_HEADER {
  NDIS_OBJECT_HEADER Header;
  NET_IFINDEX        IfIndex;
  NET_LUID           NetLuid;
  ULONG64            RequestId;
  NDIS_PORT_NUMBER   PortNumber;
  ULONG              DeviceNameLength;
  ULONG              DeviceNameOffset;
  UCHAR              Padding[4];
} NDIS_WMI_EVENT_HEADER, *PNDIS_WMI_EVENT_HEADER;

Members

Header

The NDIS_OBJECT_HEADER structure for this NDIS_WMI_EVENT_HEADER structure. Set the Type member of NDIS_OBJECT_HEADER to NDIS_WMI_OBJECT_TYPE_EVENT, the Revision member to NDIS_WMI_EVENT_HEADER_REVISION_1, and the Size member to sizeof(NDIS_WMI_EVENT_HEADER).

IfIndex

The NDIS interface index of the NDIS miniport adapter interface that is associated with the GUID.

NetLuid

The NDIS network interface name of the miniport adapter.

RequestId

An identifier for the request. If a miniport driver must complete a request immediately and it completes the request with a status of NDIS_STATUS_INDICATION_REQUIRED, the miniport driver uses this RequestId value to set the RequestId member of the associated NDIS_STATUS_INDICATION structure.

NDIS or overlying drivers can also use the RequestId to cancel a request. When a miniport driver receives a cancellation request, the miniport driver cancels any pending requests with a matching RequestId. If RequestId is zero, the miniport driver can ignore this member.

For more information about this member, see NDIS_OID_REQUEST.

PortNumber

The miniport adapter port, if any. If the GUID is not specific to a port, PortNumber is zero.

DeviceNameLength

The length, in bytes, of the device name.

DeviceNameOffset

The offset, in bytes, to the beginning of the device name from the beginning of the NDIS_WMI_EVENT_HEADER structure.

Padding[4]

This member is reserved.

Remarks

NDIS translates NDIS status indications to WMI GUID event indications.

WMI GUID event indications that are specific to NDIS 6.0 and later versions include an NDIS_WMI_EVENT_HEADER structure that is followed by the GUID-specific data, if any.
