How do you C++ class into a python?

A newb programmer here
I have a project involving pedestrian simulation
I'm planning to use libpedsim.dll in python with Ctypes but so far I cannot make the functions working
Can anyone point out how to make use of this DLL?
Link for said library: http://pedsim.silmaril.org/

Thanks guys
You are really helpful
I finally manage to access the function usin dependency walker
It seems all the function name are mangled and I have to access it with something like getattr(pedsim, "??0Tagent@Ped@@QAE@ABV01@@Z")
