Hook functions on Windows using `MinHook `_.

Quick Start:

.. code-block:: python

    import ctypes

    import ctypes.wintypes

    import cyminhook

    import win32api

    import win32con

    class MessageBoxExWHook(cyminhook.MinHook):

        signature = ctypes.WINFUNCTYPE(

            ctypes.c_int,

            ctypes.wintypes.HWND,

            ctypes.wintypes.LPCWSTR,

            ctypes.wintypes.LPCWSTR,

            ctypes.wintypes.UINT,

            ctypes.wintypes.WORD,

            use_last_error=True,

        )

        target = ctypes.windll.user32.MessageBoxExW

        def detour(self, hWnd, lpText, lpCaption, uType, langId):

            return self.original(hWnd, "Hooked", "Hooked", uType, langId)

    with MessageBoxExWHook() as hook:

        hook.enable()

        win32api.MessageBox(None, "Hello, World!", "Python", win32con.MB_OK)
