MISRA (Motor Industry Software Reliability Association).

MISRA C is a set of software development guidelines for the C programming language developed by MISRA (Motor Industry Software Reliability Association). Its aims are to facilitate code safetysecurityportability and reliability in the context of embedded systems, specifically those systems programmed in ISO C / C90 / C99.[1]
In the beginning "C" was considered unsuitable for safety critical and safety related systems, however, it was so used ...
In 1998, as a response to this situation, MISRA produced MISRA C, a set of guidelines to aid the development of safety related systems in "C" in the automotive world. Since then, MISRA C has been adopted by the wider embedded systems community and has become the dominant, international coding guidelines for the use of "C" in critical systems. The MISRA C guidelines are widely accepted as fulfilling the requirements for a language subset as required by both the 1994 MISRA Development guidelines for vehicle based software and IEC 61508.
Things move on, and now C++ is in the position once held by "C"; many people believe that it should not be used for critical systems, but its use within the field is growing and that growth is without a common set of guidelines.
MISRA has recently completed work on the production of a set of guidelines for the use of C++ in critical systems, the output of which will be a set of guidelines similar to those that were produced for "C".
The document, known as MISRA C++ Guidelines for the use of the C++ language in critical systems, was published and officially launched on 5 June 2008.
