Autoit DllCallbackRegister have a bug?

[GreenBox]

I'm sorry my english...

i try DllCallbackRegister($func, "ptr:cdecl", "ptr; ptr") but it's raise error when callback called.

only use can DllCallbackRegister($func, "ptr:cdecl", "ptr") but no idea how get param from python...

help please.

output:

E:\Users\EcmaXp\Desktop>python32 ./module1.py

['__doc__', '__name__', '__package__', 'hello'
<built-in function hello>
