Overview

A collection of useful libraries written in C++ for embedded systems.

Remarks

qLibs++ complies with most of the Motor Industry Software Reliability Association (MISRA) MISRA-C++:2008 and the SEI CERT C coding standards in order to provide a safe, reliable, and secure foundation for embedded applications.
