What are the best practices for synchronization in C++?

What are the best practices for synchronization in C++?

Some best practices include using mutexes for critical sections, avoiding deadlocks, and preferring higher-level abstractions like std::lock_guard.

Can you explain how to avoid deadlocks?

To avoid deadlocks, ensure that all threads acquire locks in a consistent order and use timeout mechanisms when trying to acquire locks.

What about using condition variables?

Condition variables are great for signaling between threads. Use them to wait for a condition to be true before proceeding.

Are there any performance considerations?

Yes, excessive locking can lead to performance bottlenecks. Minimize the scope of locks and consider lock-free data structures when possible.
