Checked C

Checked C is an extension to C that adds static and dynamic checking to detect or prevent common programming errors such as buffer overruns, out-of-bounds memory accesses, and incorrect type casts. This repo contains the specification for the extension, test code, and samples. For the latest version of the specification and the draft of the next version, see the Checked C releases page.

We are creating a modified version of LLVM/clang that supports Checked C. The code for the modified version of LLVM/clang lives in the Checked C clang repo and the Checked C LLVM repo.
