How does thread synchronization work in the pthread library?
Thread synchronization in the pthread 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 coordination.
How do barriers work in thread synchronization?
Barriers synchronize a group of threads, ensuring that all threads reach a certain point before any can proceed.
