Among all kernel objects, event kernel objects are the most basic objects. They containUsage count(Like all kernel objects), one is used to indicate that the event isAuto resetThe event is stillManual resetEventBoolean Value, And the other is used
Event objectThe time object also belongs to the kernel object, which contains a count, a Boolean value indicating whether the event is an automatic reset event or a manual reset event, another Boolean value indicating whether the event is in the
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
I. Overview
A thread is a discrete processing queue that allows different functions to be executed at the same time in the same program, this makes it very important for a function that carries out a special operation for a long time to be executed
Currently, the popular process thread synchronization and mutex control mechanism is actually implemented by the four most primitive and basic methods.
The combination of these four methods enables flexible and variable. NET and Java thread process

Differences between mutex critical section critical sessions in synchronization control
Win32 mutex is very similar to critical seciton. But He Increases elasticity at a sacrifice speed.
Control Methods for mutual exclusion of four processes or threads1. critical section: accesses public resources or code segments through multi-thread serialization, which is fast and suitable for controlling data access.2. mutex: designed to
Mutex: A Mutex object.
Mutex range: Mutex within a multi-process range can also be used for synchronization of multiple threads in the same process. If the application scenario is the Mutex of the same process class, Mutex is unnecessary, using Lock

C++11 the mutex of a threadWhy mutex is requiredIn a multitasking operating system, multiple tasks that run concurrently may require the same resource to be used. This process is a bit like, in the company department, I am using the printer while
Mutexes, as core objects of the system, can span processes (critical areas are not), and we can use mutexes to prevent programs from repeatedly booting.
Work idea:
Try to open a Mutex object with a custom name first with OpenMutex, and no such
A detailed explanation of conditional variables
At the end of the previous article, I described a more specific challenge: how it should handle the situation if a thread was waiting for a particular condition to occur. It can repeatedly lock and
The way and mechanism of process/thread synchronization, interprocess communicationOne, process/thread synchronization mechanism.Four ways of critical, mutex, event, SemaphoreDifferences between critical sections (Critical section), mutexes (mutexes)
Process is the soul of an operating system, and a software program is usually made up of several processes. Now the computer is generally used multi-channel program design and multiprocessor design (so-called 4-core, eight-core is actually referred
