       Cppcheck is a command-line tool that tries to detect bugs that your
       C/C++ compiler doesn't see. It is versatile, and can check non-standard
       code including various compiler extensions, inline assembly code, etc.
       Its internal preprocessor can handle includes, macros, and several
       preprocessor commands. While Cppcheck is highly configurable, you can
       start using it just by giving it a path to the source code.

       Analyze given C/C++ files for common errors.

           Check Cppcheck configuration. The normal code analysis is disabled
           by this flag.

           Show information messages when library files have incomplete info.

           By default Cppcheck checks all configurations. Use -D to limit the
           checking. When -D is used the checking is limited to the given
           configuration. Example: -DDEBUG=1 -D__cplusplus

           By default Cppcheck checks all configurations. Use '-U' to
           explicitly hide certain #ifdef <id> code paths from checking.
           Example: '-UDEBUG'

           Enable additional checks. The available ids are:

               Enable all checks. It is recommended to only use --enable=all
               when the whole program is scanned, because this enables

               Enable warning messages

               Enable all coding style checks. All messages with the
               severities 'style', 'performance' and 'portability' are

               Enable performance messages

               Enable portability messages

               Enable information messages

               Check for unused functions. It is recommend to only enable this
               when the whole program is scanned

               Warn if there are missing includes. For detailed information
               use --check-config

           By default none of the additional checks are enabled. Several ids
           can be given if you separate them with commas, e.g.
           --enable=style,unusedFunction. See also --std

           If errors are found, integer <n> is returned instead of default 0.
           EXIT_FAILURE is returned if arguments are not valid or if no input
           files are provided. Note that your operating system can modify this
           value, e.g. 256 can become 0.

           Print a list of all possible error messages in XML format.

           Used when certain messages should be displayed but should not cause
           a non-zero exitcode.

           Specify the files to check in a text file. One filename per line.
           When file is -, the file list will be read from standard input.

       -f, --force
           Force checking of files that have a lot of configurations. Error is
           printed if such a file is found so there is no reason to use this
           by default. If used together with --max-configs=, the last option
           is the one that is effective.

       -h, --help
           Print help text.

       -I <dir>
           Give path to search for include files. Give several -I parameters
           to give several paths. First given path is searched for contained
           header files first. If paths are relative to source files, this is
           not needed.

           Specify directory paths to search for included header files in a
           text file. Add one include path per line. First given path is
           searched for contained header files first. If paths are relative to
           source files, this is not needed.

           Path (prefix) to be excluded from configuration checking.
           Preprocessor configurations defined in headers (but not sources)
           matching the prefix will not be considered for evaluation of
           configuration alternatives.

           A file that contains a list of config-excludes.

           Force inclusion of a file before the checked file. Can be used for
           example when checking the Linux kernel, where autoconf.h needs to
           be included for every file compiled. Works the same way as the GCC
           -include option.

       -i <dir>
           Give path to ignore. Give several -i parameters to ignore several
           paths. Give directory name or filename with path as parameter.
           Directory name is matched to all parts of the path.

           Allow that Cppcheck reports even though the analysis is
           inconclusive. There are false positives with this option. Each
           result must be carefully investigated before you know if it is good
           or bad.

           Enable inline suppressions. Use them by placing comments in the
           form: // cppcheck-suppress memleak before the line to suppress.

       -j <jobs>
           Start <jobs> threads to do the checking work.

       -l <load>
           Specifies that no new threads should be started if there are other
           threads running and the load average is at least <load> (ignored on
           non UNIX-like systems)

           Forces cppcheck to check all files as the given language. Valid
           values are: c, c++

           Use library configuration.

           Maximum number of configurations to check in a file before skipping
           it. Default is 12. If used together with --force, the last option
           is the one that is effective.

           Specifies platform specific types and sizes.The available platforms

               32 bit unix variant

               64 bit unix variant

               32 bit Windows ASCII character encoding

               32 bit Windows UNICODE character encoding

               64 bit Windows

           By default the platform which was used to compile Cppcheck is used.

       -q, --quiet
           Only print something when there is an error.

       -rp, -rp=<paths>, --relative-paths;, --relative-paths=<paths>
           Use relative paths in output. When given, <paths> are used as base.
           You can separate multiple paths by ';'. Otherwise path where source
           files are searched is used. E.g. if given value is test, when
           checking test/test.cpp, the path in output will be test.cpp instead
           of test/test.cpp. The feature uses string comparison to create
           relative paths, so using e.g. ~ for home folder does not work. It
           is currently only possible to apply the base paths to files that
           are on a lower level in the directory tree.

           Report progress when checking a file.

           Match regular expression to create your own checks. E.g. rule "/ 0"
           can be used to check division by zero. This command is only
           available if cppcheck was compiled with HAVE_RULES=yes.

           Use given rule XML file. See
           https://sourceforge.net/projects/cppcheck/files/Articles/ for more
           info about the syntax. This command is only available if cppcheck
           was compiled with HAVE_RULES=yes.

           Set standard. The available options are:

               POSIX compatible code

               C code is C89 compatible

               C code is C99 compatible

               C code is C11 compatible (default)

               C++ code is C++03 compatible

               C++ code is C++11 compatible (default)

           Example to set more than one standards: 'cppcheck --std=c99
           --std=posix file.cpp'

           Suppress a specific warning. The format of <spec> is: [error
           id]:[filename]:[line]. The [filename] and [line] are optional.
           [error id] may be * to suppress all warnings (for a specified file
           or files). [filename] may contain the wildcard characters * or ?.

           Suppress warnings listed in the file. Each suppression is in the
           format of <spec> above.

           Format the error messages. E.g.
           '{file}:{line},{severity},{id},{message}' or
           '{file}({line}):({severity}) {message}'. Pre-defined templates:
           gcc, vs

       -v, --verbose
           More detailed error reports

           Print out version information

           Write results in XML to error stream

           Select the XML file version. Currently versions 1 and 2 are
           available. The default version is 1.

       The program was written by Daniel Marjamaki and Cppcheck team. See
