The C++ Build Insights SDK is compatible with Visual Studio 2017 and later. To see the documentation for these versions, set the Visual Studio Version selector control for this article to Visual Studio 2017 or later. It's found at the top of the table of contents on this page.

The TRACE_INFO_DATA structure describes a trace being analyzed or relogged.

Syntax

typedef struct TRACE_INFO_DATA_TAG
{
    unsigned long           LogicalProcessorCount;
    long long               TickFrequency;
    long long               StartTimestamp;
    long long               StopTimestamp;

} TRACE_INFO_DATA;

Members

Name Description
LogicalProcessorCount The number of logical processors on the machine where the trace was collected.
TickFrequency The number of ticks per second to use when evaluating a duration measured in ticks.
StartTimestamp This field is set to a tick value captured at the time the trace was started.
StopTimestamp This field is set to a tick value captured at the time the trace was stopped.

Remarks

Subtract StartTimestamp from StopTimestamp to obtain the number of ticks elapsed during the whole trace. Use TickFrequency to convert the resulting value into a time unit. For an example that converts ticks to time units, see EVENT_DATA.
