Sometimes, you need to manipulate low-level functionality (C APIs, etc) from high-level languages (Python).
Eg. Force the low-level side calls directly to your own Python override functions. This repo will help you do that.

To hook & unhook a function, you only need to write codes as the following

import ctypes
from PyHooking import PyHooking, load_external_shared_library, arch, bits

# define the hook function

mylib = load_external_shared_library(f"Examples/mylib_{arch}_{bits}")

@PyHooking.CPrototype(ctypes.CFUNCTYPE(None, ctypes.c_char_p))
def hk_print_message(message):
    message = f"Invoked `hk_print_message('{message.decode('utf-8')}')`"
    PyHooking().invoke(mylib.print_message, message.encode())

# perform hooking

PyHooking().hook(mylib.print_message, hk_print_message)

mylib.print_message(b"This is a string from Python code")
mylib.c_invoke_print_message()

# perform unhooking

PyHooking().unhook(mylib.print_message)

mylib.print_message(b"This is a string from Python code")
mylib.c_invoke_print_message()

# result

'''
Invoked `hk_print_message('This is a string from Python code')`
Invoked `hk_print_message('This is a string from C code')`
This is a string from Python code
This is a string from C code
