Typo in __init__.py

[WombakulusBenediktusXII]

In init.py is in line 74 in create_voidp() is in if kwarg instead of kwargs. This leads to a NameError that always occurs and thus the function is no longer properly usable.

Thanks for this, I was struggling for days on this one thing, and didn't understand why I was getting the NameError every time.
