I’ve worked with mutexes quite a bit when dealing with multi-threading, and they really are essential for keeping things running smoothly.
A mutex (short for mutual exclusion) is like a lock that ensures only one thread can access a shared resource at a time. When a thread locks the mutex, other threads trying to lock it have to wait until it’s released.
This prevents race conditions and data corruption when multiple threads try to modify the same data simultaneously. In short, they make sure threads don’t step on each other’s toes!
