1. What is a kernel object? The kernel object is a memory block allocated by the operating system. The memory block is a data structure used to manage various object information. When the application needs to interact with the system device, it will

We often want to open a program without opening another instance. After exploration, we found that there are two solutions available: One is through the process, and the other is through the mutex class.1. Using mutex, mutex has an output parameter

With the introduction of multithreading, you may feel that you need to understand some issues related to thread sharing resources. NET Framework provides many classes and data types to control access to shared resources.Consider a situation we often

There are four common methods for Thread Synchronization in a process: 1. The ccriticalsection can be used when multiple threads access a dedicated shared resource. A thread with a critical section can access protected resources or code segments. If

Let's say that a data structure means thread security means that only one thread can rewrite it at a time. In this way, even if multiple threads access it, it will not generate data that is very unexpected to the thread. Dictionary in C # Is Not

Chapter 1: Error Handling   Use the getlasterror function to obtain more error information, or use @ err and HR (vs2005) in the Monitoring Box to obtain error information, not just error numbers.   Chapter 2: character and string processing 　　 In an

The thread synchronization mechanism in user mode is highly efficient. If you need to consider thread synchronization, you should first consider the thread synchronization method in user mode. However, user-mode thread synchronization is limited.

Vs. Net multi-thread control statement mutex 1. Monitor. Enter and monitor. Exit The monitor class grants an object lock to a single thread to control access to the object. Object locks provide the ability to restrict access to code blocks (usually

When you need to create, open, and operate various kernel objects, the system needs to create and operate several types of kernel objects, such as access symbol object, event object, file object, file ing object, I/O completed port object, job

  Mutex is a class derived from waithandle, which ensures that multiple threads are mutually exclusive on a resource or code block. Mutex is defined as follows: Public sealed class mutex: waithandle { Public mutex (); Public mutex (bool

Mutex)   Mutex represents a mutex data structure and is also used as a binary signal lamp. A mutex is basically a multi-task sensitive binary signal. It can be used for synchronizing multiple tasks. It is often used to protect critical code
