How can I avoid deadlocks in C++11?

To avoid deadlocks in C++11, you can use several strategies such as using std::lock, avoiding nested locks, and implementing a timeout mechanism.

What is std::lock and how does it help?

std::lock is a function that locks multiple mutexes at once, preventing deadlocks by ensuring that all locks are acquired in a consistent order.

Can you give an example of using std::lock?

Sure! Here's a simple example:

#include <mutex>

std::mutex m1, m2;

void func() {
    std::lock(m1, m2);
    std::lock_guard<std::mutex> lg1(m1, std::adopt_lock);
    std::lock_guard<std::mutex> lg2(m2, std::adopt_lock);
    // critical section
}

What are some other strategies to prevent deadlocks?

Other strategies include using a lock hierarchy, avoiding holding locks while waiting for other resources, and using try-lock mechanisms.
