What is synchronization in pthreads?

What is synchronization in pthreads?

Synchronization in pthreads refers to techniques used to control the access of multiple threads to shared resources, ensuring data consistency.

Why is synchronization important in multithreading?

It's crucial because without synchronization, multiple threads may read and write shared data simultaneously, leading to race conditions and unpredictable behavior.

Can you explain some common synchronization mechanisms in pthreads?

Sure! Common mechanisms include mutexes, condition variables, and semaphores, each serving different purposes for thread coordination.

How do I implement a mutex in my pthread program?

To implement a mutex, you need to initialize it with pthread_mutex_init, lock it with pthread_mutex_lock, and unlock it with pthread_mutex_unlock.

What happens if I forget to unlock a mutex?

If you forget to unlock a mutex, it can lead to deadlocks, where threads are waiting indefinitely for the mutex to be released.
