" 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"

" checking. Preprocessor configurations defined in\n"

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

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

" 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"

" * all\n"

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

" * style\n"

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