Function prototype: Intpthread_mutex_init (pthread_mutex_t * restrict_mutex, constpthread_mutextattr_t * restrictattr) this function is mainly used to initialize mutex locks in multiple threads. If attr is null, it is the default attribute, and the

Transferred fromHttp://weihe6666.iteye.com/blog/1170141 A condition variable is a mechanism for synchronizing global variables shared by threads. It mainly includes two actions: one thread waits for the condition variable to be established and

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

Implementation of thread mutex: Windows has two methods: mutex and critical section, and Linux has a mutex lock for the pthread library. Windows Thread Synchronization generally uses the critical section. This article mainly discusses the

Introduction POSIX thread is short for pthread, and POSIX thread isPOSIXStandard thread. This standard defines the internal API creation and thread manipulation.   Function The thread library implements the POSIX thread standard, usually

When multiple threads are interacting with an object, controls need to be in place to ensure that the threads don't adversely affect one another. this chapter deals with issues that can introduce subtle errors in your application. an application

Qt provides support for threads, the basic form includes platform-independent thread classes, thread-safe event transmission, and a global Qt library mutex, allowing you to call the Qt method from different threads. This document is provided to

Multithreading and network development for iOS: NSThread and iosnsthread Master haomeng is devoted to his contribution and respects the author's Labor achievements. Do not repost them. If the article is helpful to you, you are welcome to donate to

IOS development-thread security for multi-thread DevelopmentA resource may be shared by multiple threads, that is, multiple threads may access the same resource, for example, multiple threads access the same object, the same variable, the same file,

Troubleshooting of InnoDB database deadlocks and innodb database deadlocks Scenario Description DeadlockLoserDataAccessException exception (Deadlock found when trying to get lock; try restarting transaction...) occurs during table update

Introduction to the basic API of the multi-thread demo program for producer consumer in linux: intpthread_create (pthread * thread, pthread_attr_t * attr, void * (* start_routine) (* void ), void * arg); the first parameter is the second parameter

Innodb is a multi-thread concurrent storage engine. internal read/write operations are implemented using multiple threads. Therefore, innodb implements a highly efficient concurrency synchronization mechanism. Innodb does not directly use the latch

In Java multi-threaded programming, wait () is used to bring the current thread into the blocking state, and notify () is used to wake the current thread and continue execution. Although they control the thread status, they are actually all methods

Signal is a programming architecture designed by E. W. Dijkstra at the end of 1960s. Dijkstra's model is related to railway operations: assuming a railway is a single line, only one train is allowed at a time. The signal will be used to synchronize
