Function name decoration (decorated name) modeThe name decoration of a function (decorated name) is a string that the compiler creates during compilation to indicate the definition or prototype of a function. The link program or other tool sometimes needs to specify the function's name decoration to locate the correct position of the function. In most cases the programmer does not need to know the function's name decoration, and the link program or other tool will automatically differentiate the

stack top pointer is also modified. You can also remove the top stack from the stack, which is called pop. After the stack pops up, an element at the top of the stack changes to the top of the stack, and the top pointer of the stack changes accordingly. When a function is called, the caller pushes the parameter to the stack in sequence and then calls the function. After the function is called, the caller obtains data in the stack for calculation. After function compute is completed, the caller

makes the C function parameters in the stack order from right to left. The specific reason is: the C-mode parameter in the stack order (right-to-left) The advantage is that you can dynamically change the number of parameters. The stack analysis shows that the front parameters are pressed on the bottom of the stack, from left to right. Unless you know the number of arguments, the leftmost parameter cannot be obtained by relative displacement of the stack pointer (it is easy to locate the paramet

// 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 method from right to left and clears the stack when it exits. After compiling a function, VC adds an underline prefix to the function name, and adds "@" and the number of bytes of the parameter to the function name. 2. c call conventions (which are desc

The syntax of the programming language is rigorous. The function call Convention used is stdcall. In MicrosoftC ++ Series In C/C ++ compilers, PASCAL macros are often used to declare this call

communication between the host and workflow. As this is an important concept for building an interactive workflow, let's take a look at how it is designed into WF. In order to establish a user interaction model in WF, we must design the conventions used to provide many events and methods. Both the workflow and the host process should understand this agreement. The constructed Convention/interface must be marked with the [externaldataexchange ()]

convention. Because visual c ++ uses the _ cdecl call method by default, _ stdcall should be used to call DLL in VC. According to the C compilation method, the _ cdecl call Convention only underlines the output function name, such as _ functionname. (3) _ fastcall: The _ fastcall call is faster. It passes parameters through the internal registers of the CPU. (In fact, it uses ECx and EDX to transmit the fi

convention. If you use a variety of languages and different compilers, the problem of processing standards in different languages will arise. To enable programmers to handle multi-language mixed programming, Niu people have established rules to specify how to call functions and pass parameters. These rules are called call conventions. For example, a programmer writes a function named SQRT in Pascal. This function carries a floating point parameter

parameter in the stack order (right-to-left) The advantage is that you can dynamically change the number of parameters. The stack analysis shows that the front parameters are pressed on the bottom of the stack, from left to right. Unless you know the number of arguments, the leftmost parameter cannot be obtained by the relative displacement of the stack pointer. This becomes the number of left parameters is indeterminate, just as the number of dynamic parameters in the opposite direction.Theref
