C++ 20 (2a) New Features - Efficient Atomic Waiting

The video tutorial discusses the use of atomic bool variables and threads, focusing on the lock wait function. It explains how threads can be notified using a lock, similar to a condition variable but more lightweight. The method is efficient for a large number of threads but cannot be compiled on major compilers yet. The next video will cover lightweight access coordination.

What are the implications of using atomic variables instead of mutexes in multi-threading?

Discuss the limitations mentioned regarding the compilation of the code on major compilers.
