mutex release

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

Mutex is a key. When a person takes the key, they can enter a room. When they come out, the key is handed over to the first in the queue. Generally, this method is used to serialize the access to the critical section code to ensure that the Code is

. NET synchronous and asynchronous Mutex (12),. net synchronous mutex This essay continued: a set of. NET synchronization and asynchronous thread security (11) This article and the next two articles will introduce the last major knowledge point of

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

The mutex Kernel Object ensures that a thread exclusively accesses resources. The behavior characteristics of mutex kernel objects are similar to those of key code segments, but they are kernel objects, and key code segments are user mode objects,

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

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

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
