What are some advanced synchronization techniques in C programming?

Advanced synchronization techniques in C include mutexes, semaphores, condition variables, and read-write locks. Would you like to know more about any specific technique?

Can you explain how mutexes work?

Mutexes, or mutual exclusions, are used to prevent multiple threads from accessing a shared resource simultaneously. They ensure that only one thread can access the resource at a time, which helps avoid race conditions.

What is a race condition?

A race condition occurs when two or more threads access shared data and try to change it at the same time. If the threads are not properly synchronized, it can lead to inconsistent or unexpected results.

How do semaphores differ from mutexes?

Semaphores can allow multiple threads to access a resource up to a certain limit, while mutexes only allow one thread at a time. Semaphores are often used for signaling between threads.
