推荐答案

当两个或多个线程需要访问共享资源时同时，系统需要一个同步机制来确保一次只有一个线程使用该资源。 Mutex是一个同步原语，它只允许对一个线程的共享资源进行独占访问。如果一个线程获得一个互斥锁，那么想要获取该互斥锁的第二个线程将被挂起，直到第一个线程释放该互斥锁。

Hi,

When two or more threads need to access a shared resource at the same time, the system needs a synchronization mechanism to ensure that only one thread at a time uses the resource. Mutex is a synchronization primitive that grants exclusive access to the shared resource to only one thread. If a thread acquires a mutex, the second thread that wants to acquire that mutex is suspended until the first thread releases the mutex.
