TrackPopupMenu has the wrong return type in certain context

[Craftplacer]

Actual behavior

CsWin32 generates the function signature for TrackPopupMenu and TrackPopupMenuEx as bool, which is correct for using no parameters. The "Return value" section however states that the return value will be an UINT_PTR (IntPtr, int?) when TPM_RETURNCMD has been passed.

Expected behavior

Our function sig that we have written is this:

[DllImport(nameof(User32))]
internal static extern int TrackPopupMenuEx(IntPtr hmenu, uint fuFlags, int x, int y, IntPtr hwnd, IntPtr lptpm);

Repro steps

1. NativeMethods.txt content:

TrackPopupMenu
TrackPopupMenuEx

3. Any of your own code that should be shared?

unsafe
{
    // this turns into a type compiler error
    int clickedItemId = PInvoke.TrackPopupMenuEx(_hMenu, (uint)TRACK_POPUP_MENU_FLAGS.TPM_RETURNCMD, x, y, hWnd);
}

Context

• CsWin32 version: 0.1.506-beta
• Target Framework: net5.0-windows

UINT_PTR translates to IntPtr.
