What are the uses of semaphores in C++?

What are semaphores in C++ and how are they used?

Semaphores are synchronization primitives used to control access to a common resource in concurrent programming.

Can you explain how semaphores differ from mutexes?

Certainly! Semaphores allow multiple threads to access a resource, while mutexes provide exclusive access to a single thread.

What are some practical examples of using semaphores in C++?

You can use semaphores for managing access to a pool of resources, like database connections or thread pools.

Are there any libraries in C++ that provide semaphore functionality?

Yes, the C++11 standard library includes <semaphore> in the form of std::counting_semaphore and std::binary_semaphore.
