Analyze function

  • Artikkeli

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 Analyze function is used to analyze an Event Tracing for Windows (ETW) trace obtained from MSVC while tracing a C++ build. The events in the ETW trace are forwarded sequentially to an analyzer group provided by the caller. This function supports multi-pass analyses that allow forwarding the event stream to the analyzer group multiple times in a row.

Syntax

template <typename... TAnalyzerGroupMembers>
RESULT_CODE Analyze(
    const char*                                   inputLogFile,
    unsigned                                      numberOfPasses,
    StaticAnalyzerGroup<TAnalyzerGroupMembers...> analyzerGroup);

template <typename... TAnalyzerGroupMembers>
RESULT_CODE Analyze(
    const wchar_t*                                inputLogFile,
    unsigned                                      numberOfPasses,
    StaticAnalyzerGroup<TAnalyzerGroupMembers...> analyzerGroup);

Parameters

TAnalyzerGroupMembers
This parameter is always deduced.

inputLogFile
The input ETW trace that you wish to read events from.

numberOfPasses
The number of analysis passes to run on the input trace. The trace gets passed through the provided analyzer group once per analysis pass.

analyzerGroup
The analyzer group used for the analysis. Call MakeStaticAnalyzerGroup to create an analyzer group. To use a dynamic analyzer group obtained from MakeDynamicAnalyzerGroup, first encapsulate it inside a static analyzer group by passing its address to MakeStaticAnalyzerGroup.

Return Value

A result code from the RESULT_CODE enum.
