Cyclone: A Safe Dialect of C

Abstract

Cyclone is a safe dialect of C. It has been designed from the ground up to prevent the bu#er overflows, format string attacks, and memory management errors that are common in C programs, while retaining C's syntax and semantics. This paper examines safety violations enabled by C's design, and shows how Cyclone avoids them, without giving up C's hallmark control over low-level details such as data representation and memory management.
