pthread lock mutex

　　The Mutex (mutex) is the abbreviation for "Mutual exclusion". Mutexes are the primary way to implement thread synchronization and to protect simultaneous write-shared data.Mutex protection for shared data is like a lock. In Pthreads, only one

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

In gemfield's article "from pthread to qthread", we learned about the basic usage of threads, but most of the content was said to be discussed in this article, that is, thread synchronization. Gemfield has a metaphor in "from process to thread", so

Because pthread implements parallel computing based on shared memory, the use of shared variables in multiple threads has many synchronization problems. It may be okay to read the same variable in multiple threads, but it may cause inconsistency 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

Tian haili 2013-08-10 Android-encapsulated synchronization classes mainly include mutex (automutex) and condition. The previous article analyzes their external use. This article describes how they are implemented through encapsulation of pthread

When we need to control access to shared resources, we can use a simple lock-up method to control. We can create a read / write program that shares a shared buffer and uses a mutex to control access to the buffer. 　The function pthread_mutex_init ()
