I'm attempting to get some platform specific information from the struct SDL_SysWMinfo.

我正在尝试从结构SDL_SysWMInfo获取一些特定于平台的信息。

A minimal example that demonstrates the problem:

演示该问题的最小示例：

#include <SDL.h>
#include <SDL2/SDL_syswm.h>

void* getWindowHandle(SDL_Window* window)
{
    SDL_SysWMinfo wmi{};
    SDL_VERSION(&wmi.version);

    if (!SDL_GetWindowWMInfo(window, &wmi)) return nullptr;

    return wmi.info.win.window;
}

int test()
{
    if (SDL_Init(SDL_INIT_VIDEO) != 0) return 1;

    SDL_Window* window = SDL_CreateWindow("Test", 50, 50, 1024, 768, 0);

    if (window == nullptr) return 1;
    
    void* windowHandle = getWindowHandle(window);
    
    SDL_DestroyWindow(window);
    SDL_Quit();
}

I get these compile errors:

我得到以下编译错误：

I can't figure out why I'm seeing this. Including the windows header (i.e. #include <windows.h>) doesn't seem to help.

我不明白为什么我会看到这个。包括窗口标题(即#INCLUDE )似乎没有什么帮助。

I'm compiling on windows 10 64 bit, using Visual Studio build tools 2022.

我正在使用Visual Studio构建工具2022在Windows 10 64位上进行编译。

Would anyone have any idea what I'm doing wrong here?

有人知道我做错了什么吗？

Here is the compile command:
