the interesting stuff happens. But there are also plenty of exciting things happening on the error handling flow, too. Although not universally loved/used, exceptions are a powerful mechanism of maneuvering crash. We'll poke into these mechanisms and see how we can leverage them in our application error handling. Did I mention threads? Routing exceptions between threads... oh my! ## S Advanced Installer stuff happens ## Exceptional C++ But there are also plenty of exciting things happening on the error handling flow, too ## Exceptional C++ Although not universally loved, exceptions are a powerful mechanism
