    im not 100% sure but if you are talking about your code and wanting it to work in windows, I think you have to add a windows header file to access that stuff. Havn't learned it myself yet but that will be to come.

    or probably this would be the answer to your mystical question,

    win32api is made using the c language, so by using these win32 functions, your c code becomes a win32 program,

    Code:
    #include <windows.h> 
    
    LRESULT CALLBACK WindowFunc(HWND, UINT, WPARAM, LPARAM); 
    char szWinName[] = "MyWin"; 
    
    int WINAPI WinMain(HINSTANCE hThisInst, HINSTANCE hPrevInst, 
    LPSTR lpszArgs, int nWinMode) 
    { 
            HWND hwnd; 
            MSG msg; 
            WNDCLASSEX wcl; 
    
            wcl.cbSize = sizeof(WNDCLASSEX); 
    
            wcl.hInstance = hThisInst; 
            wcl.lpszClassName = szWinName; 
            wcl.lpfnWndProc = WindowFunc; 
            wcl.style = 0; 
    
            wcl.hIcon = LoadIcon(NULL, IDI_APPLICATION); 
            wcl.hIconSm = NULL; 
            wcl.hCursor = LoadCursor(NULL, IDC_ARROW); 
    
            wcl.lpszMenuName = NULL; 
            wcl.cbClsExtra = 0; 
            wcl.cbWndExtra = 0; 
    
            if(!RegisterClassEx(&wcl)) return 0; 
    
            hwnd = CreateWindow( 
            szWinName, 
            "A Window", 
            WS_OVERLAPPEDWINDOW, 
            CW_USEDEFAULT, 
            CW_USEDEFAULT, 
            CW_USEDEFAULT, 
            CW_USEDEFAULT, 
            NULL, 
            NULL, 
            hThisInst, 
            NULL); 
    
            ShowWindow(hwnd, nWinMode); 
            UpdateWindow(hwnd); 
    
            while(GetMessage(&msg, NULL, 0, 0)) 
            { 
                    TranslateMessage(&msg); 
                    DispatchMessage(&msg); 
            } 
            return msg.wParam; 
    } 
    
    
    LRESULT CALLBACK WindowFunc(HWND hwnd, UINT message, 
    WPARAM wParam, LPARAM lParam) 
    { 
            switch(message) 
            { 
                    case WM_DESTROY: 
                    PostQuitMessage(0); 
                    break; 
                    default: 
                    return DefWindowProc(hwnd, message, wParam, lParam); 
            } 
    return 0; 
    }
