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)
