What are the best practices for multithreading in C++11?

What are the best practices for multithreading in C++11?

Some best practices include using std::thread for thread management, avoiding data races with mutexes, and using condition variables for synchronization.

Can you explain how to use mutexes effectively?

Certainly! Use std::mutex to protect shared data. Always lock the mutex before accessing the data and unlock it afterward. Consider using std::lock_guard for automatic locking.

What about using atomic variables?

Atomic variables, like std::atomic, allow for lock-free programming. They ensure that operations on the variable are performed atomically, which can improve performance in certain scenarios.

Are there any common pitfalls to avoid?

Yes, common pitfalls include deadlocks, race conditions, and overusing locks. Always analyze your locking strategy and prefer finer-grained locks when possible.
