OID_TAPI_GET_CALL_STATUS
The OID_TAPI_GET_CALL_STATUS OID requests the miniport driver to return the current status of the specified call.
Support for this request is mandatory.
This request uses an NDIS_TAPI_GET_CALL_STATUS structure, defined as follows:
typedef struct _NDIS_TAPI_GET_CALL_STATUS {
IN ULONG ulRequestID;
IN HDRV_CALL hdCall;
OUT LINE_CALL_STATUS LineCallStatus;
} NDIS_TAPI_GET_CALL_STATUS, *PNDIS_TAPI_GET_CALL_STATUS;
The members of this structure contain the following information:
ulRequestID
Reserved.hdCall
Specifies the miniport driver's handle to the call for which the current status should be returned.LineCallStatus
Specifies the virtual address of a variable-size structure of type LINE_CALL_STATUS. For more information, see ndistapi.h.The miniport driver fills this structure with call status information to complete this request successfully.
The structure at LineCallStatus has at least sizeof(LINE_CALL_STATUS) 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
