+This example demonstrates how to wrap the Windows ``MessageBoxW`` function so
 that it supports default parameters and named arguments. The C declaration from
 the windows header file is this::
 
    WINUSERAPI int WINAPI

 Here is the wrapping with :mod:`ctypes`::
 
    >>> from ctypes import c_int, WINFUNCTYPE, windll
-   >>> from ctypes.wintypes import HWND, LPCSTR, UINT
-   >>> prototype = WINFUNCTYPE(c_int, HWND, LPCSTR, LPCSTR, UINT)

 A second example demonstrates output parameters.  The win32 ``GetWindowRect``
 function retrieves the dimensions of a specified window by copying them into
