C++函数调用约定
_cdecl约定:
参数:从右向左依次入栈
堆栈平衡:调用方平衡

#include "pch.h"
#include <iostream>

int __cdecl getMaxNumber(int a, int b, int c)
{
    int temp = a > b ? a : b;
    return temp > c ? temp : c;
}

int main()
{
    int iMax = 0;
    iMax = getMaxNumber(10, 30, 16);
    printf("iMAx = %d\n", iMax);
}

push 参数二

_stdcall约定:

堆栈平衡:被调用方自己平衡

#include "pch.h"

push 参数一 //参数入栈顺序:从右向左依次入栈
push 参数二
push 。。。
push edx
push ecx //寄存器传递
call Fun //调用函数,在函数内进行堆栈平衡,retn XX


naked约定:
参数:从右向左依次入栈
堆栈平衡:调用方平衡

push 参数一 //参数入栈顺序:从右向左依次入栈
push 参数二
push 。。。
push 参数N
call Fun //调用函数
add esp,XX //堆栈平衡

C++函数调用方式约定stdcall,cdecl,pascal,naked,thiscall,fastcall
