NDIS_TAPI_GET_EXTENSION_ID (Windows Embedded CE 6.0)

1/6/2010

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.

Syntax

typedef struct _NDIS_TAPI_GET_EXTENSION_ID { 
  ULONG ulRequestID; 
  ULONG ulDeviceID; 
  LINE_EXTENSION_ID LineExtensionID; 
} 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
