For information on rulesets, refer to "Options for rulesets" section. The ruleset_files parameter specifies one or more semicolon-delimited ruleset files to use for analysis of external files. For example, code analysis analyzes external files and reports defects even when /external:W0 is specified. The /external:Wn option doesn't affect code analysis. Templates defined in external headers are treated as non-external by using the /external:templates- option. When the /analyze:external- option is set, code analysis skips any files specified as external, except templates from external files. By default, code analysis analyzes external header files just like other files. Then, use compiler option /analyze:plugin EspXEngine.dll to use the EspXEngine plug-in. If you're building in a developer command prompt window, first set the Esp.Extensions environment variable to specify the Concurrenc圜heck.dll extension: set Esp.Extensions=Concurrenc圜heck.dll These checks raise warnings in the C261XX range, such as C26100 through C26167. The EspXEngine.dll plug-in uses Concurrenc圜heck.dll to implement concurrency-related code analysis checks. You can use an absolute file path for an extension, or specify a relative path from the directory that contains EspXEngine.dll. Use a semicolon ( ) to delimit the extensions, as shown in the example. For example: set Esp.Extensions=Concurrenc圜heck.dll CppCoreCheck.dll When you build on the command line, you can use the Esp.Extensions environment variable to specify EspXEngine extensions. They check for defects for concurrency issues, CppCoreGuidelines violations, inappropriate uses of enum values as indexes, HRESULT values, or VARIANT values, respectively. Visual Studio includes these extensions for EspXEngine: Concurrenc圜heck.dll, CppCoreCheck.dll, EnumIndex.dll, HResultCheck.dll, and VariantClear.dll. Some plug-ins, like EspXEngine.dll, which ships with Visual Studio, employ extensions that can do further analysis. To use another plug-in with the code analysis engine, specify it by using the /analyze:plugin option. The code analysis engine comes with some built-in plug-ins that detect various defects. The code analysis engine uses plug-ins to help find specific categories of defects. Here's an example: /analyze:plugin"c:\path\to\Esp圎ngine.dll". However, if the path is enclosed in double-quotes, you can't have a space between /analyze:plugin and the file path. For example, you can write /analyze:plugin Esp圎ngine.dll. Space between /analyze:plugin and the plugin_dll file path is optional if the path doesn't require double-quotes ( "). Analysis plugin optionsĮnables the specified code analysis plug-in DLL for code analysis. For more information, see /WX (Warning level). Tells the compiler not to treat code analysis warnings as errors even when the /WX option is used. The number parameter specifies the size in bytes of the stack frame that generates warning C6262. Larger values cause more thorough checking, but the analysis might take longer. The number parameter specifies the maximum number of code paths to analyze. Turns off analysis output to the console or Visual Studio Output window. We recommend you use this option only if the code passes code-generation syntax checks without errors or warnings. If the program isn't free of code-generation warnings, analysis results might be unreliable. ![]() However, the compiler won't report other warnings that it might find during the code generation pass. Compiler errors still prevent code analysis from running. The /analyze:only option makes the compiler skip the code generation pass, and does code analysis directly. Code analysis also creates a log file named, where filename is the name of the analyzed source file.īy default, the compiler compiles the code to generate object files before code analysis runs. analyze- is the default behavior.īy default, analysis output goes to the console or the Visual Studio Output window like other error messages. Use /analyze- to explicitly turn off analysis. analyze:ruleset ruleset_files Arguments General analysis options analyze:rulesetdirectory ruleset_directories analyze:projectdirectory project_directory
