Complete Modern C++ - Propagating Exceptions Across Threads

The video tutorial explains how promises can be used to propagate exceptions between threads. It covers setting exceptions in promises using try-catch blocks and the creation of exception pointers for sharing exceptions across threads. The tutorial demonstrates exception propagation from the main thread to a task and vice versa, highlighting the automatic creation of exception pointers by the runtime. It concludes by emphasizing the utility of promises for data sharing between threads without manual synchronization.
