OID_TAPI_GET_EXTENSION_ID uses the NDIS_TAPI_GET_EXTENSION_ID structure when it requests the miniport driver to return the extension identifier for the specified line device.

Support for this request is optional.

typedef struct _NDIS_TAPI_GET_EXTENSION_ID {   ULONGulRequestID;ULONGulDeviceID;LINE_EXTENSION_IDLineExtensionID;} NDIS_TAPI_GET_EXTENSION_ID, *PNDIS_TAPI_GET_EXTENSION_ID;

Members

  • ulRequestID
    [in] Reserved.

  • ulDeviceID
    [in] Specifies the link or data channel to be queried. This was set up in a preceding OID_TAPI_GET_ID request.

  • LineExtensionID
    [out] Pointer to a structure of type LINE_EXTENSION_ID.

    If the miniport driver supports device-specific extensions, it fills this structure with the extension identifier of these extensions. Otherwise, it fills this structure with zeros.

    For a bound protocol, a valid extension identifier cannot consist of all zeros.

Remarks

The MiniportQueryInformation function can return one of the following:

  • NDIS_STATUS_SUCCESS
  • NDIS_STATUS_PENDING
  • NDIS_STATUS_TAPI_RESOURCEUNAVAIL
  • NDIS_STATUS_FAILURE

Requirements

OS Versions: Windows CE .NET 4.0 and later.
Header: Ntddndis.h and Ndistapi.h.
