OID_TAPI_GET_CALL_INFO

  • Article

The OID_TAPI_GET_CALL_INFO OID requests the miniport driver to return detailed information about the specified call.

Support for this request is mandatory.

This request uses an NDIS_TAPI_GET_CALL_INFO structure, defined as follows:

    typedef struct _NDIS_TAPI_GET_CALL_INFO {
         ULONG ulRequestID;
         IN HDRV_CALL hdCall;
         OUT LINE_CALL_INFO LineCallInfo;
 
    } NDIS_TAPI_GET_CALL_INFO, *PNDIS_TAPI_GET_CALL_INFO;

The members of this structure contain the following information:

  • ulRequestID
    Reserved.

  • hdCall
    Specifies the miniport driver's handle to the call for which it should return information.

  • LineCallInfo
    Specifies the virtual address variable-size data structure of type LINE_CALL_INFO. For more information, see ndistapi.h.

    The miniport driver fills this structure with call-related information to complete this request successfully.

    The structure at LineCallInfo has at least sizeof(LINE_CALL_INFO) bytes reserved.

The MiniportQueryInformationfunction can return one of the following:

NDIS_STATUS_SUCCESS

NDIS_STATUS_PENDING

NDIS_STATUS_TAPI_INVALCALLHANDLE

NDIS_STATUS_TAPI_RESOURCEUNAVAIL

NDIS_STATUS_FAILURE
