function calling

The last post talked about the optimization of the garbage collector. After a long time, I didn't continue to talk about finalize (in fact, this is a bit of a problem with GC ). Today, let's take a look at the performance topics related to finalize

Data Pointer In embedded system programming, it is often required to read and write content in a specific memory unit, and the compilation has a corresponding mov command, other programming languages except C/C ++ do not have the ability to directly

Functions in JavaScript are different from other languages. Each function is maintained and run as an object. Through the properties of function objects, you can easily assign a function to a variable or pass the function as a parameter. Before

Powershell function call problems and cause analysis... This code is used for testing and focuses on function calling... At first, I wrote it like this and found that no matter how the function returns 0, the function is as follows: The content

// This article is transferred from the Internet Several Concepts of function calling: _ stdcall, _ cdecl .... 1. _ stdcall is the default calling method of the PASCAL program. It is usually used in Win32 API. The function uses the stack pressure

Function parameters are the internal communication methods between the outside and the function. For a function with parameters, the function has a data transfer relationship during function calling. Check the Code: // Call a functionMax (5,

Essence of C/C ++ left (3) Conversion of left values   3. Conversion from function to pointer   The purpose of converting a function into a pointer is the same as that of converting an array to a pointer. It is used to convert a symbol into a

Implementation principle and performance analysis of PHP Functions Author: Baidu engineer hdk PrefaceIn any language, a function is the most basic component unit. What are the features of PHP functions? How is function calling implemented? What is

Call of common member functions Starting from this part, we will not only use memory information printing for exploration, but also track and observe the compilation code generated by the compiler to understand how the compiler implements these

Postscript Based on the previous discussion, we can see that as long as virtual inheritance is involved, the code generated when accessing the member variables of the parent class is quite inefficient, the address of the member variable needs to be

You do not need to know about the Function calling rules (call conventions) most of the time. However, if you need cross-language programming, such as calling a DLL written by VC using Delphi, you need to know. Microsoft's VC adopts the _ cdecl

Function call Method -- _ thiscall and _ cdecl ,__ stdcall First, __thiscall is a class call method. The biggest difference between it and other call methods is:_ Thiscall adds a class pointer parameter to each function.Class AA{Void BB (int cc

In terms of performance optimization, we always pay attention to the 80-20 principle, that is, 20% of the program consumes 80% of the running time. Therefore, to improve the efficiency, we mainly consider improving the 20% code. Do not optimize the
