  I some how fixed it after some research it should be the following way: I'm trying to access a c++ function from python using ctypes python code: policy_list = POINTER(c_char_p)() Handle = c_void_p() Getpolicy = lib.func() x = GetPolicy(Handle, policy_list) how to access it is policy_list[0], .....
