What are some common thread synchronization techniques in C++?

In C++, common thread synchronization techniques include mutexes, condition variables, and semaphores. Would you like to know more about any specific technique?

Can you explain how mutexes work?

Sure! A mutex (short for mutual exclusion) is a synchronization primitive that prevents multiple threads from accessing a shared resource simultaneously. When a thread locks a mutex, other threads trying to lock it will be blocked until the mutex is unlocked.

What about condition variables?

Condition variables are used to block a thread until a particular condition is met. They work with mutexes to allow threads to wait for certain conditions to be true before proceeding.

How do semaphores differ from mutexes?

Semaphores allow a certain number of threads to access a resource concurrently, while mutexes only allow one thread at a time. Semaphores can be used for signaling between threads as well.
