3.6 IusbTrace6 interface

The IUsbTrace6 interface is the sixth interface for the UsbTrace object. It inherits and extends some

trace-related functionality exposed via the IUsbTrace5 interface.

IID : A1F83FCC-265A-44E3-837F-42A8C27074C1

3.6.1 IUsbTrace6::IsLevelDecodeFinished

HRESULT IsLevelDecodeFinished(

[in] long level_id,

[out,retval] BOOL* decode_is_finished )

Retrieves progress status of decoding levels process. If level decoding is finished, returns true.

Parameters

level_id Desired level to retrieve decoding status like Transaction/Transfer

decode_is_finished Pointer to Boolean value that specifies decoding status

Return values

Remarks

After opening traces, decoding process of upper levels starts in background processes or through a

function call for higher levels. This decoding is time consuming process, however any other process on

desired level like transactions need to check of decoding finish before starting process.

The level ID parameter could be one of these values:

DECODE_LEVEL_PACKET = 0, // USB_TRA_LEVEL_PACKETS

DECODE_LEVEL_TRANSACTION = 1, // USB_TRA_LEVEL_TRANSACTIONS

DECODE_LEVEL_SPLIT = 2, // USB_TRA_LEVEL_SPLITS

DECODE_LEVEL_TRANSFER = 3, // USB_TRA_LEVEL_TRANSFERS

DECODE_LEVEL_PTP_TRANSACTION = 8, // USB_TRA_LEVEL_PTP_TRANSACTION

DECODE_LEVEL_PTP_OBJECT = 9, // USB_TRA_LEVEL_PTP_OBJECT

DECODE_LEVEL__PTP_SESSION = 10, // USB_TRA_LEVEL_PTP_SESSION

DECODE_LEVEL_SCSI = 11, // USB_TRA_LEVEL_SCSI_OPERATION

DECODE_LEVEL_PTP_GRP = 13, // USB_TRA_LEVEL_PTP_GROUP
