How does synchronization work in the pthreads library?

Synchronization in the pthreads library is achieved using mutexes, condition variables, and barriers to manage access to shared resources.

Can you explain what a mutex is?

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

What are condition variables used for?

Condition variables are used to block a thread until a particular condition is met, allowing for efficient thread synchronization.

How do I implement a simple mutex in my code?

You can implement a mutex using pthread_mutex_t in C. Initialize it with pthread_mutex_init, lock it with pthread_mutex_lock, and unlock it with pthread_mutex_unlock.
