c调用方式

#include "stdafx.h" #include <iostream> using namespace std; int __cdecl fun1(int a, int b) { cout << "param1: " << a << "\t" << "param2: " << b << endl; return a+b; } int __stdcall fun2(int a, int b) { cout << "param1: " << a << "\t" << "param2: " << b << endl; return a+b; } /*int __pascal fun3(int a, int b) { cout << "param1: " << a << '\t' << "param2: " << b << endl; return a + b; }*/ int __cdecl fun4(int a, ...) { cout << "resutl = " << a << endl; return a; } int main(int argc, char* argv[]) { __asm { push 1 //__cdecl的调用约定, 1入栈等同于b=1 push 2 //接着是2入栈等同于a=2 call fun1 //调用函数 add esp,8 //返回main push 10 push 20 call fun2; /*push 100 push 200 call fun3;*/ } fun4(111, 222); cout << "fun exexute finished..." << endl; return 0; }
