Apparently it's also using ctypes to interface with the DLLs. I was rather close but was not aware of the magical '.value' extension that is required to access the contents of a char pointer. However I'm not interested in re-creating the wheel, so the fact that it's already out there saves me tons of time.
For those that use this though, I did have a problem actually with the example shown in the documention. The ARGetSchema helper function didn't work. First it's using the variable 'schema' and trying to reference it without a definition. And then some of the fields within the structure were being called with incorrect definitions. I started trying to fix the problems, but then wondered if maybe there's another file that I need to reference.
I don't need this function at the moment, but I'm worried that if there's another file that I don't have correctly configured I may have problems elsewhere. Did anyone else who uses pyARS have this problem?

Marc,
there is a python module called pyars that covers most of the ARS API and CMDB functions.
http://sourceforge.net/projects/pyars/
We use it for automizing migration stuff for ARS and find it quite useful and stable.
Cheers
Dirk
