--- A Lock-Free Atomic Shared Pointer in Modern Cpp - Timur Doumler - CppCon 2022 std::shared_ptr is a standard smart pointer utility widely used in modern C . A commonly overlooked property of std::shared_ptr is that while its control block is thread-safe, the shared_ptr itself isn’t. To fix this, C 20 introduced std::atomic＜std::shared_ptr＞. However, existing implementations are typically not lock-free, rendering std::atomic＜std::shared_ptr＞ useless for low-latency and real-time applications. What would it take to implement a lock-free atomic shared_ptr? In this talk, we first discuss the motivation and use case, review how std::shared_ptr works and the history of std::atomic＜std::shared_ptr＞. We then look at existing implementations and different implementation strategies. Finally, we present a new implementation of a lock-free atomic shared_ptr which is portable to multiple platforms. --- Timur Doumler Timur Doumler is the Developer Advocate for C tools at JetBrains and an active member of the ISO C standard committee.
