What is a mutex"Mutex" is the abbreviated form of the term "mutually exclusive (mutually exclusive)", which is the mutex amount. The mutex is similar to the monitor mentioned in the critical section, where only the line friend with the mutex has

Differences between semaphore and mutex: ScopeSemaphore: process or thread (Linux only)Mutex lock: between threads LockSemaphores: as long as the semaphores value is greater than 0, other threads can successfully sem_wait, And the semaphores value

Thread Synchronization and mutex: mutex lockWhy do we need mutex lock? In a multitasking operating system, the same resource may be used for multiple tasks running simultaneously. This process is a bit similar. In the company department, while I was

Mutex is a simple form of synchronization (called mutex )). The mutex prohibits multiple threads from entering the protected code "critical section" at the same time ). Therefore, at any time, only one thread is allowed to enter such a code

Multi-threaded threads synchronize mutex (the function is the same as that of the criticalsection, which ensures that only one thread can access Shared resources at a certain time point, but is a kernel object. Therefore, the access speed is slower
