mutex

Sometimes, we need to run only one instance of our program, the author of their own procedures have such a situation, so I have to explore some. After a while, finally small harvest, do not dare to enjoy, in pole published for your reference. Since

Asp.net| Comparison | multithreading A more classic multithreaded learning code. 1, the use of multithreading synchronization problem.2, the use of the sequence of multithreading problems. If you are interested please read the following code

A condition variable compensates for the lack of a mutex by allowing the thread to block and wait for another thread to send a signal, which is often used in conjunction with a mutex lock. When used, a condition variable is used to block a thread,

This article mainly introduces the use of PowerShell mutex parameters, this article gives two code examples to solve the use of mutually exclusive parameters, the need for friends can refer to the Sometimes PowerShell functions need to be mutually

This article supporting source code Many programs, such as Winamp,ttplayer,realplayer, and so on are automatically activated before an instance of the function, in fact, this thing is very simple, in VB can be used app.hinstance to determine

Program As long as the main entrance in your program is as follows, your program can only have one instance of the program at a time when it is running, such as Winamp is this, when it is running, and then hit the program, it will not run an

As I said before, each thread has its own resources, but the code area is shared, that is, each thread can perform the same function. The problem with this may be that several threads execute a function at the same time, causing data chaos and

The 1.monitor.enter (object) method is to acquire the lock, the Monitor.Exit (object) method is to release the lock, which is the most commonly used two methods of Monitor, of course, in the use of the process in order to avoid acquiring the lock

Introduction A condition variable is a mechanism for synchronizing a global variable shared between threads, consisting mainly of two actions: one thread waits for the condition variable to hang (the CPU is no longer in use), and another thread

The main idea of Windows network user password guessing algorithm is to use Windows provided window enumeration function EnumWindows () to find the network login window. Use the child Window enumeration function enumchildwindows () or

1. The first definition of pthread_cond_wait is this The pthread_cond_wait () and pthread_cond_timedwait () functions are used to blocks on a condition variable. They are called with a mutex locked by the calling thread or undefined behaviour would

Commonly used to create multithreaded functions under Linux pthread_create (pthread_t * thread, pthread_attr_t * attr, void * (*start_routine) (void*), void *args); The first parameter is used to hold the thread information. The second parameter

Mutexes are mutexes that are widely used in multithreaded programming. In this paper, we discuss the implementation of the mutex of Doug Lea's concurrent Toolkit in a wide-flow case. In Doug Lea's concurrent toolkit, the mutex implements the sync

Author of the question: Zhou Xiang This is a program that I wrote in the semester of the operating system class and was organized into an article. I was posted on CSTC's Forum by my best friend Zeng: http://cstc.net.cn/bbs/viewtopic.php?t=457, here,

Some libraries may provide only asynchronous methods, and ASP.net is indeed synchronized, and this time there is a problem: the page will not perform the callback function until it is displayed. The process I need is to perform validation in the

/* Note at compile time, to manually connect the library * * #include #include #include #include static int value = 0; pthread_mutex_t Mutex; void func (void* args) {while (1) {pthread_mutex_lock (&mutex);

This article mainly introduces the initial introduction of Ruby multithreaded programming, thread is the focus of Ruby programming learning and difficult, the need for friends can refer to the A traditional program has a separate thread that

Cancelwaitabletimer This function is used to cancel a timer operation that can wait Callnamedpipe This function is called by a client process that wants to communicate through a pipeline Connectnamedpipe Instructs

When the thread calls fork, a copy of the entire process address space is created for the child process. The child processes inherit the state of all mutexes, read-write locks, and condition variables from the parent process by inheriting copies of

The singleton mode implemented by double detection lock (double-checked locking) has considerable value in multithreading application. The Ace_singleton template class is used extensively in the implementation of Aces to convert generic classes into
