3.9 IUsbTrace10 interface

The IUsbTrace10 interface is an additional interface for the UsbTrace object. It inherits and extends

some trace-related functionality exposed via the IUsbTrace9 interface.

IID : AC4DC05E-3B20-4233-BDE6-F92B3A185B28

3.9.1 IUsbTrace10::ExportTransactionsWithPacketsToCsv

HRESULT ExportTransactionsWithPacketsToCsv (

[in] BSTR file_name,

[in, defaultvalue(-1)] long unit_from,

[in, defaultvalue(-1)] long unit_to );

Exports the USB Transactions and packets level of the trace into a text file in CSV format and allows

exporting a range of packets.

Parameters

file_name String providing the full pathname of the trace export file

unit_from Beginning packet number when you are exporting a range of packets. Value –1

makes the first packet of the exported trace be the first packet of the trace.

unit_to Ending packet number when you are exporting a range of packets.

Value –1 makes the last packet of the exported trace be the last packet of the

trace.

Return values

ANALYZERCOMERROR_UNABLESAVE Unable to export trace file

Remarks

Use this method if you want to export a recorded or opened trace into a text file in CSV format. If display

options apply to this trace (see ITrace::ApplyDisplayOptions or

IAnalyzer::LoadDisplayOptions), then hidden units would not be exported.

If a unit range is specified and it is invalid (for example, unit_to is more than the last unit number in the

trace, or unit_from is less than first unit number in the trace, or unit_from is more then unit_to) then

unit range adjusts automatically.
