Summary
Microsoft has released lib0xc, an open-source C programming library designed to make C code safer for systems programming. The library provides a set of C standard library-adjacent APIs that help developers write more type-safe and bounds-safe code, addressing common vulnerabilities in C programming. While it cannot make C completely safe at the language level, it aims to reduce risks through stricter compilation warnings and safer utility functions. The project is hosted on GitHub and targets developers working on systems-level software who want to mitigate memory safety issues inherent in C.

"Make C safer" is a nebulous and amorphous goal, and it is more apt as a programming language design statement than a modest set of utilities.
lib0xc's goal is to make it possible for projects to turn on as many warnings as possible and to fail
