How do you ensure thread safety in a multi-threaded application?

How do you ensure thread safety in a multi-threaded application?

To ensure thread safety, you can use synchronization mechanisms like mutexes, semaphores, or locks to control access to shared resources.

Can you explain what a mutex is?

A mutex, or mutual exclusion, is a synchronization primitive that prevents multiple threads from accessing a shared resource simultaneously.

What are some common pitfalls when using mutexes?

Common pitfalls include deadlocks, where two or more threads are waiting on each other to release resources, and priority inversion.

How can I avoid deadlocks in my application?

To avoid deadlocks, you can implement a timeout mechanism, use a lock hierarchy, or avoid holding multiple locks at once.
