HMonitor undeclared in dxgi.h with WINAPI_FAMILY_GAMES macro

Question

code is as follows:

#pragma once  
#define WINAPI_FAMILY WINAPI_FAMILY_GAMES  
#define NOMINMAX  
#define NOKANJI  
#define WIN32_LEAN_AND_MEAN  
  
#include <windows.h>  
#include <dxgi.h>  
#include <d3d11.h>  

compilation results in E0020 identifier "HMONITOR" is undefined

looking into <dxgi.h> on line 210:

if !defined(HMONITOR_DECLARED) && !defined(HMONITOR) && (WINVER < 0x0500)  
#define HMONITOR_DECLARED  
#if 0  
typedef HANDLE HMONITOR;  
  
#endif  
DECLARE_HANDLE(HMONITOR);  
#endif  
typedef struct DXGI_OUTPUT_DESC  
    {  
    WCHAR DeviceName[ 32 ];  
    RECT DesktopCoordinates;  
    BOOL AttachedToDesktop;  
    DXGI_MODE_ROTATION Rotation;  
    HMONITOR Monitor;  
    } 	DXGI_OUTPUT_DESC;  

and <windef.h> on line 107:

#pragma region Application Family  
#if WINAPI_FAMILY_PARTITION(WINAPI_PARTITION_APP | WINAPI_PARTITION_SYSTEM)  
  
DECLARE_HANDLE(HMONITOR);  
  
#endif /* WINAPI_FAMILY_PARTITION(WINAPI_PARTITION_APP | WINAPI_PARTITION_SYSTEM) */  
#pragma endregion  

How do you resolve this without changing WINAPI_FAMILY to WINAPI_FAMILY_DESKTOP_APP?

Hello @jacob kristersson ,
Welcome to Microsoft Q&A!

You can modify the value of WINVER in the header file to make it less than 0x0500, like #define WINVER 0x0499

For details, please refer to this document Update WINVER and _WIN32_WINNT.

Thank you.
