Pthread - 互斥量（Mutex） 和 条件变量（Condition variable）

Mutex

The mutex, officially known as mutual exclusion, serves as a mechanism for thread synchronization. In the context of accessing shared resources, the mutex functions similarly to a lock: only one thread can acquire the lock at any given time. This ensures that other threads must wait until the current thread releases the lock before attempting to acquire it again. Thus, the mutex enables multiple threads to access shared resources in a controlled manner. The common use case for mutex is in scenarios where multiple threads need to ac
