C++ 20 (2a) New Features - Lightweight Access Coordination

The video tutorial introduces counting semaphores, a synchronization primitive added in C20. It explains their initialization and operations like acquire and release, which manage thread synchronization by controlling access to shared resources. The tutorial highlights that semaphores were not available in C until C20, and current major compilers may not support them. The next video will cover latches and barriers.

How does the semaphore ensure that only one thread is sleeping at a time?

What is the significance of the semaphore being a synchronization primitive in programming?
