VSS Services API

[jmdharkness]

I am trying to extract data about the current Volume Shadow Copies generated on my machine through system restore points. I can get a nice output using VSSADMIN list shadows, however the tool I am currently working on would be better suited if the same information could be retrieved through API calls. Does anyone have experience in this area ? The output returned from VSSADMIN list shadows is:
