Exception Handling in C++ Multithreading

Learn how to safely handle exceptions in multithreaded C++ programs — and why forgetting this can crash your entire application. In this video, we walk through the rules of exception propagation across threads, how to communicate failures using std::promise, std::exception_ptr, and modern C++20 tools like std::jthread. 🔹 Why exceptions don't cross thread boundaries 🔹 Catching exceptions inside threads the right way 🔹 std::promise & std::future: One-shot exception channels 🔹 std::exception_ptr: The safe way to transfer and rethrow 🔹 RAII + locking: Prevent leaks when exceptions occur We’ll also cover: What happens when exceptions escape threads (hint: std::terminate) Structured error handling in thread pools using central queues Visual stack diagrams and thread-safe exception propagation Perfect for C++ developers writing robust, modern multithreaded code in C++17/20. 📌 Full code and diagrams included. 📘 Requires C++11 or newer (C++20 for jthread). 🔔 Subscribe for more modern C++ deep dives.
