Cppcheck is a static analysis tool for C/C++ code.

Below is the list of options that are supported:
--append=<file> This allows you to provide information about functions by providing an implementation for them. --config-exclude=<dir> 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. --config-excludes-file=<file> A file that contains a list of config-excludes -D<ID> Define preprocessor symbol. Unless --max-configs or --force is used, Cppcheck will only check the given configuration when -D is used. Example: '-DDEBUG=1 -D__cplusplus'. -U<ID> Undefine preprocessor symbol. Use -U to explicitly hide certain #ifdef <ID> code paths from checking. Example: '-UDEBUG' --enable=<id> Enable additional checks. The available ids are: * all Enable all checks. It is recommended to only use --enable=all when the whole program is scanned, because this enables unusedFunction. * warning Enable warning messages * style Enable all coding style checks. All messages with the severities 'style', 'performance' and 'portability' are enabled. * performance Enable performance messages * portability Enable portability messages * information Enable information messages * unusedFunction Check for unused functions. It is recommend to only enable this when the whole program is scanned. * missingInclude Warn if there are missing includes. For detailed information, use '--check-config'. Several ids can be given if you separate them with commas. See also --std --file-list=<file> Specify the files to check in a text file. Add one filename per line. When file is '-,' the file list will be read from standard input. -f, --force Force checking of all configurations in files. If used together with '--max-configs=', the last option is the one that is effective. -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. --includes-file=<file> 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. --include=<file> 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 or file> Give a source file or source file directory to exclude from the check. This applies only to source files so header files included by source files are not matched. Directory name is matched to all parts of the path. --inconclusive 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. --inline-suppr Enable inline suppressions. Use them by placing one or more comments, like: '// cppcheck-suppress warningId' on the lines before the warning to suppress. --library=<cfg> Load file <cfg> that contains information about types and functions. With such information Cppcheck understands your code better and therefore you get better results. The std.cfg file that is distributed with Cppcheck is loaded automatically. For more information about library files, read the manual. --max-configs=<limit> 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. --platform=<type>, --platform=<file> Specifies platform specific types and sizes. The available builtin platforms are: * unix32 32 bit unix variant * unix64 64 bit unix variant * win32A 32 bit Windows ASCII character encoding * win32W 32 bit Windows UNICODE character encoding * win64 64 bit Windows * avr8 8 bit AVR microcontrollers * native Type sizes of host system are assumed, but no further assumptions. * unspecified Unknown type sizes --std=<id> Set standard. The available options are: * posix POSIX compatible code * c89 C code is C89 compatible * c99 C code is C99 compatible * c11 C code is C11 compatible (default) * c++03 C++ code is C++03 compatible * c++11 C++ code is C++11 compatible (default) * c++14 C++ code is C++14 compatible (default) More than one --std can be used: 'cppcheck --std=c99 --std=posix file.c' --suppress=<spec> Suppress warnings that match <spec>. The format of <spec> is: <error id>:<filename>:<line> The <filename> and <line> are optional. If <error id> is a wildcard '*', all error ids match. --suppressions-list=<file> Suppress warnings listed in the file. Each suppression is in the same format as <spec> above.
In addition to general severity levels, the following tool specific severity levels can be specified:
information(equivalent to general severity level
style(equivalent to general severity level
performance(equivalent to general severity level
portability(equivalent to general severity level
