最近简单的学一下 Win32 编程
开始想着 WinMain 参数那么长，想用宏给它简化一下。

我是这么写的：

#define WinBegin(...) WINAPI WinMain(HINSTANCE hNowInstance, HINSTANCE hPrevInstance, PTCHAR lpCmdLine, int nShowCmd)

但编译时提示以下警告：
warning: in expansion of macro 'WinBegin'
这要怎么解决？

警告而已, 但你要保证调用的地方正确

先看看正确的声明
int WINAPI   WinMain( HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR l pCmdLine, int nShowCmd );
int WINAPI  wWinMain( HINSTANCE hInstance, HINSTANCE hPrevInstance, LPWSTR lpCmdLine, int nShowCmd );
int WINAPI _tWinMain( HINSTANCE hInstance, HINSTANCE hPrevInstance, LPTSTR lpCmdLine, int nShowCmd );

再看看你的
WINAPI WinMain(HINSTANCE hNowInstance, HINSTANCE hPrevInstance, PTCHAR lpCmdLine, int nShowCmd)
牛头不对马嘴，四不像呀

#include <windows.h>
#include <tchar.h>

#define WinBegin(...) WINAPI _tWinMain( HINSTANCE hNowInstance, HINSTANCE hPrevInstance, LPTSTR lpCmdLine, int nShowCmd )

int WinBegin(你声明了接受参数，却不使用)
{
    return 0;
}
