How can I prevent deadlocks in C++11?

To prevent deadlocks in C++11, you can use several strategies such as avoiding nested locks, using lock hierarchies, or employing timed locks.

What is a lock hierarchy?

A lock hierarchy is a method where you define a global order for acquiring locks. By always acquiring locks in a consistent order, you can prevent circular wait conditions that lead to deadlocks.

Can you give an example of using a timed lock?

Sure! You can use std::unique_lock with a timeout. For example:

std::unique_lock<std::mutex> lock(mutex, std::defer_lock);
if (lock.try_lock_for(std::chrono::seconds(1))) {
    // Lock acquired, proceed with work
} else {
    // Handle the timeout
}

Are there any libraries that help with deadlock prevention?

Yes, libraries like Boost provide advanced locking mechanisms that can help manage locks more effectively and reduce the risk of deadlocks.
