mutex unlock

1. Synchronization of threads with mutex 1.1. Mutex for threadsA set of mutex functions specifically for thread mutexes is defined in the POSIX thread. A mutex is a simple locking method to control access to a shared resource, which has only two

Mutex lock mechanismMutual Exclusion (mutex) is a mechanism used in multi-threaded programming to prevent two threads from simultaneously reading and writing the same public resources (such as global variables. ToCodeSlice into one critical area

I. Use mutex lock 1. initialize mutex Pthread_mutex_t mutex = pthread_mutex_initializer; // static initialization mutex Int pthread_mutex_init (pthread_mutex_t * mutex, pthread_mutexattr_t * ATTR); // dynamically initialize mutex Int

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

I. mutex lock In essence, mutex is a lock that provides protection for access to shared resources. 1. Initialization: In Linux, the thread mutex data type is pthread_mutex_t. Before use, initialize it: For the mutex of static allocation, you can set

Critical Section) A convenient way to ensure that only one thread can access data at a certain time point. Only one thread is allowed to access Shared resources at any time. If multiple threads attempt to access the critical section at the same

Anyone who has worked on a slightly larger project knows that they strive for program stability and convenient scheduling and use a large number of threads. Almost every module has a dedicated thread processing function. The mutex and condition
