“WINAPI"是什么?在主函数中是什么意思?

2021-12-05 00:00:00 windows c winapi c++ winmain

你能解释一下 WinMain() 函数中的 WINAPI 词吗?

Could you please explain to me the WINAPI word in the WinMain() function?

以最简单的方式.. 

#include <windows.h>

int -->WINAPI<-- WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, 
    LPSTR lpCmdLine, int nCmdShow)
{
    MessageBox(NULL, "Goodbye, cruel world!", "Note", MB_OK);
    return 0;
}

这只是一些 Windows 时髦模式吗?

Is it just some Windows funky mode?

它有什么作用?或者更确切地说，我还没有遇到过这个 C++ 特性是什么?

What does it do? Or rather what is this C++ feature I haven't encountered yet?

推荐答案

WINAPI 是一个宏，其计算结果为 __stdcall，Microsoft 特定的关键字，指定被调用者清理堆栈的调用约定.函数的调用者和被调用者需要就调用约定达成一致，以避免破坏堆栈.

WINAPI is a macro that evaluates to __stdcall, a Microsoft-specific keyword that specifies a calling convention where the callee cleans the stack. The function's caller and callee need to agree on a calling convention to avoid corrupting the stack.
