DestroyWindow function Null safety user32

int DestroyWindow(
  1. int hWnd
)

Destroys the specified window. The function sends WM_DESTROY and WM_NCDESTROY messages to the window to deactivate it and remove the keyboard focus from it. The function also destroys the window's menu, flushes the thread message queue, destroys timers, removes clipboard ownership, and breaks the clipboard viewer chain (if the window is at the top of the viewer chain).

BOOL DestroyWindow(
  HWND hWnd
);

  final _DestroyWindow = _user32.lookupFunction<Int32 Function(IntPtr hWnd),
      int Function(int hWnd)>('DestroyWindow');
