"Syntax:\n"

" cppcheck [OPTIONS] [files or paths]\n"

"\n"

"If a directory is given instead of a filename, *.cpp, *.cxx, *.cc, *.c++, *.c,\n"

"*.tpp, and *.txx files are checked recursively from the given directory.\n\n"

"Options:\n"

" --addon=<addon>\n"

" Execute addon. i.e. cert.\n"

" --cppcheck-build-dir=<dir>\n"

" Analysis output directory. Useful for various data.\n"

" Some possible usages are; whole program analysis,\n"

" incremental analysis, distributed analysis.\n"

" --check-config Check cppcheck configuration. The normal code\n"

" analysis is disabled by this flag.\n"

" --check-library Show information messages when library files have\n"

" incomplete info.\n"

" --config-exclude=<dir>\n"

" Path (prefix) to be excluded from configuration\n"

" checking. Preprocessor configurations defined in\n"

" headers (but not sources) matching the prefix will not\n"

" be considered for evaluation.\n"

" --config-excludes-file=<file>\n"

" A file that contains a list of config-excludes\n"

" --doc Print a list of all available checks.\n"

" --dump Dump xml data for each translation unit. The dump\n"

" files have the extension .dump and contain ast,\n"

" tokenlist, symboldatabase, valueflow.\n"

" -D<ID> Define preprocessor symbol. Unless --max-configs or\n"

" --force is used, Cppcheck will only check the given\n"

" configuration when -D is used.\n"

" Example: '-DDEBUG=1 -D__cplusplus'.\n"

" -U<ID> Undefine preprocessor symbol. Use -U to explicitly\n"

" hide certain #ifdef <ID> code paths from checking.\n"

" Example: '-UDEBUG'\n"

" -E Print preprocessor output on stdout and don't do any\n"

" further processing.\n"

" --enable=<id> Enable additional checks. The available ids are:\n"

" * all\n"

" Enable all checks. It is recommended to only\n"

" use --enable=all when the whole program is\n"

" scanned, because this enables unusedFunction.\n"

" * warning\n"

" Enable warning messages\n"

" * style\n"

" Enable all coding style checks. All messages\n"

" with the severities 'style', 'performance' and\n"

" 'portability' are enabled.\n"

" * performance\n"

" Enable performance messages\n"

" * portability\n"

" Enable portability messages\n"

" * information\n"

" Enable information messages\n"

" * unusedFunction\n"

" Check for unused functions. It is recommend\n"

" to only enable this when the whole program is\n"

" scanned.\n"

" * missingInclude\n"

" Warn if there are missing includes. For\n"

" detailed information, use '--check-config'.\n"

" Several ids can be given if you separate them with\n"

" commas. See also --std\n"

" --error-exitcode=<n> If errors are found, integer [n] is returned instead of\n"

" the default '0'. '" << EXIT_FAILURE << "' is returned\n"

" if arguments are not valid or if no input files are\n"

" provided. Note that your operating system can modify\n"

" this value, e.g. '256' can become '0'.\n"

" --errorlist Print a list of all the error messages in XML format.\n"

" --exitcode-suppressions=<file>\n"

" Used when certain messages should be displayed but\n"

" should not cause a non-zero exitcode.\n"

" --file-list=<file> Specify the files to check in a text file. Add one\n"

" filename per line. When file is '-,' the file list will\n"

" be read from standard input.\n"

" -f, --force Force checking of all configurations in files. If used\n"

" together with '--max-configs=', the last option is the\n"

" one that is effective.\n"
