What should be return value for WM_CONTEXTMENU?

I'm handling a WM_CONTEXTMENU to show a pop up menu.

According to docs there is no return value.

Return value
No return value.

https://learn.microsoft.com/en-us/windows/win32/menurc/wm-contextmenu

Instead the docs say this:

If a window does not display a shortcut menu it should pass this message to the DefWindowProc function

Therefor since I'm showing a pop up menu I should not call DefWindowProc, which means I should return a value from handler.
But that's an issue because the docs say there is no return value.

example:

case WM_CONTEXTMENU:
     // Show pop up menu
     OnContextMenu(WPARAM wParam, LPARAM lParam);
     return // what?

     // We handled WM_CONTEXTMENU therefore DefWindowProc must not be called
     // But there is no return value

default:
     DefWindowProc (msg, wParam, lParam);

Well I guess we could just return anything, but what is the correct way to handle this event?

I think you can simply return 0 😏

BTW: If you call DefWindowProc(), you should return its return value.

Yes it seems return value is not important but I'm unable to find some examples to see how others are handling this message.

I know, return DefWindowProc(), thanks for reminder.
