ctypes, windll question

[Tzury]

I followed the tutorial about ctypes and I still cannot figure out how
to call a method of a calss within the dll.

For example:
a dll named 'foo' contain a class named 'bar' which expose a method
named 'baz'.

if I either do:

mydll = windll.foo
mycls = mydll.bar

or
mycls = windll.foo.bar

or
mycls = windll.foo.bar()

I get an erros: "function 'bar' not found " which is true since while
bar is a class. Yet, I need to know how to create an instance of this
inner class so I can access its public methods.
