How can I prevent deadlocks in C++?

How can I prevent deadlocks in C++?

To prevent deadlocks in C++, you can use several strategies such as avoiding nested locks, using a timeout for locks, or implementing a lock hierarchy.

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 lock hierarchy?

Sure! If you have two locks, A and B, always acquire lock A before lock B in your code. This way, you avoid situations where one thread holds A and waits for B while another holds B and waits for A.

What are some other strategies to avoid deadlocks?

Other strategies include using lock-free data structures, applying resource allocation graphs, and implementing deadlock detection algorithms.
