Towards an Automotive ‘Safer Subset’ of C
The C programming language is becoming more and more widely used in the automotive industry for electronic control systems, some of which have safety-related aspects. This paper studies the use of the C language and the reasons for this use. Because of the safety concerns with the language, there is a need to provide guidance to the industry on its use. The paper describes the work that has been carried out under the auspices of the MISRA consortium to develop an automotive ‘safer subset’ of C. The rationale behind the work is presented, along with a brief description of the contents of the Guidelines produced.
