I remember writing a HOOK API article (C/C ++ HOOK API (in-depth analysis of the principle-loadlibrarya). The main principle of this article is to construct a code byte, modify the first 16 bytes of the loadlibrarya function, and then jump to the custom function. When you call a normal function, unhook it again. In this way, when you call a function again, the unhook and

I often encounter hooks when I look at the phpwind source code, but after searching for it for a long time, I still have a clue about it. I don't want to know this. The predecessors can give me a more detailed explanation or relevant links. when phpwind source code is used, hook is often encountered.
But after searching for a long time, I still have no clue about this.
I hope the predecessors who know this can give a more detailed explanation or relat

The WIN32 subsystem must be notified about the creation of the new process.To ensure the success of any of these steps, all of its preceding steps must be successful (you cannot create an executable process object without a handle to the executable area; You cannot map an executable area without a file handle, and so on). Therefore, if we decide to quit any of these steps, all subsequent steps wi
Method swizzling Principle
Calling a method in Objective-c is actually sending a message to an object, and the only way to find the message is by selector's name. By using the dynamic characteristics of objective-c, we can realize the corresponding method of selector in the Run-time, so as to hook up the method.Each class has a list of methods that store the selector name and the mapping relationship of the method implementation. IMP is a bit like a
Some time ago I have written a "use of the underlying keyboard hook screen any button", and put it on my blog. The title of this article has changed "shielding" to "intercept", which is obviously stronger than the previous version. For the DLL that was written previously, there's a less-than-ideal place where you can only mask. If you want to add some "little gestures" before masking, you can only modify DLLs, add code to the LowLevelKeyboardProc func
Describes how to use the Hook technique in Python development and the pythonhook technique.
What is a Hook is to add some hooks to an existing method so that some additional processing is performed before or after the method is executed, so what is the function of the Hook technique and why we need to use it? In fact, if a project has sufficient considerations in
This article mainly introduces how to use Hook to interpret the source code of the CI framework. the Function Extension Method of PHP files is analyzed. The Hook principle and the related skills of extending the CI framework are analyzed. If you need a friend, refer to the example in this article to describe how to use the Hook to interpret the source code of the

My first essay, a brief introduction to the classic inline hook technology.Hook-and-take (hooking) is a technique for intercepting information, changing the flow of a program, and adding new features. Hook-and-take technology is diverse, with the hook-and-Win32 API technology known as API Hook-and-take. It is commonly

It is possible that this thief is specialized in such intelligence, thieves know, often in the window know before take action!
And the thief will take different action plan for different news, and its action plan is usually already prepared;
Of course, the thief is not interested in any news, the information is not interested in the need to develop a corresponding action plan.
Summary: This "thief" is the
See the source, Runtime.getruntime () Addshutdownhook (Shutdownhook);
Google what it means: Add a closed hook in the JVM, and when the JVM shuts down, it executes all the hooks that have been set up in the system by means of Addshutdownhook, and the JVM shuts down when the system finishes executing the hooks. So these hooks can be used for memory cleanup, object destruction, and so on when the JVM shuts down.
Before you know how to close the
