Out of curiosity, for anyone out there who is using 3.3 Pro/INTRALINK Toolkit, are the PIVSession* functions available?
They are definately in 3.3, and I believe they existed all the way back to 3.0, but were part ofPTC's undocumented internal API.
You just needed the correct header files (which have changed over time) and then you could link and call these functions.
