What is Misra C 2012?




Misra C 2012 is a document that provides a set of rules and recommendations for writing safe and secure code in the C programming language. It covers various aspects of the language, such as syntax, semantics, data types, operators, expressions, control structures, functions, pointers, arrays, strings, preprocessor directives, libraries, and concurrency. The main goal of Misra C 2012 is to prevent errors and vulnerabilities that may arise from undefined or unspecified behavior, implementation-defined behavior, or non-portable constructs in the C language.


Why is Misra C 2012 important?




Misra C 2012 is important because it helps developers to write high-quality code that is consistent, readable, maintainable, testable, and compliant with industry standards and best practices. It also helps to avoid common pitfalls and bugs that may cause system failures, crashes, security breaches, or unexpected results. By following Misra C 2012 guidelines, developers can reduce the risk of introducing defects and increase the confidence in their code quality.


Misra C 2012 is especially relevant for critical systems, such as embedded systems, automotive systems, medical devices, aerospace systems, military systems, or industrial control systems. These are systems that have high requirements for safety, reliability, performance, or security. Any error or malfunction in these systems may have severe consequences for human lives, property, or the environment. Therefore, it is essential to use a rigorous and proven approach to ensure the correctness and robustness of the code.

  • Applying all applicable rules and directives from Misra C 2012, unless a deviation is justified and documented.



  • Using a consistent coding style and naming convention throughout the project.



  • Using comments and documentation to explain the purpose and functionality of the code.



  • Using modular and structured design and programming techniques.



  • Using appropriate data types and avoiding implicit conversions or casts.



  • Using defensive programming techniques and checking for error conditions.



  • Using static and dynamic analysis tools to verify and test the code.



  • Reviewing and auditing the code for quality and compliance.



What are the benefits of Misra C 2012?




Using Misra C 2012 can bring many benefits to your project, such as:


  • Improving the quality, reliability, and maintainability of your code.



  • Reducing the number of defects, bugs, and vulnerabilities in your code.



  • Increasing the confidence and trust in your code quality.



  • Facilitating code reuse and portability across different platforms and compilers.



  • Enhancing communication and collaboration among developers and stakeholders.



  • Satisfying regulatory or contractual requirements for safety or security standards.

What are the main features of Misra C 2012?




Misra C 2012 has several features that make it different from previous versions of Misra C and from the standard C language. Some of these features are:


  • Misra C 2012 is based on the ISO/IEC 9899:1999 (C99) standard, with some restrictions and extensions.



  • Misra C 2012 has three categories of rules: mandatory, required, and advisory. Mandatory rules must be followed without any deviation. Required rules should be followed unless there is a strong justification for deviation. Advisory rules are recommendations that may be ignored if there is a good reason.



  • Misra C 2012 has two categories of directives: mandatory and advisory. Mandatory directives must be followed without any deviation. Advisory directives are recommendations that may be ignored if there is a good reason.



  • Misra C 2012 has a set of decidable rules, which are rules that can be checked by a tool with no false positives or false negatives. These rules are marked with a D in the document.



  • Misra C 2012 has a set of undecidable rules, which are rules that cannot be checked by a tool with no false positives or false negatives. These rules are marked with a U in the document.



  • Misra C 2012 supports some features of the ISO/IEC 9899:2011 (C11) and ISO/IEC 9899:2018 (C18) standards, such as generic selection, static assertions, alignment specification, and atomic operations. These features are covered by an amendment document (MISRA C:2012 AMD4) [4].



  • Misra C 2012 provides a set of permits, which are predefined deviation permits for some rules in certain situations. These permits are published in a separate document (MISRA C:2012 Permits) [5].
