How do I handle user login in a multithreaded application?

To handle user login in a multithreaded application, you need to ensure thread safety when accessing shared resources.

What are some common issues I might face with thread safety?

Common issues include race conditions, deadlocks, and inconsistent data states. Using locks or semaphores can help.

Can you give an example of using locks for user login?

Sure! You can use a mutex to lock the login function, ensuring that only one thread can process a login request at a time.

What if I want to allow multiple logins simultaneously?

In that case, consider using a thread-safe data structure to manage user sessions, allowing concurrent logins.
