How can we abstract these calls behind the Query API?
And what is the use case for these?

The use for this raw data is to calculate with them instead of using PdhCalculateCounterFromRawValue. See W2K3 SDK beginning at site 4629 for more example. I don't know whether it make sense to offer this API. In the example above i use PdhCalculateCounterFromRawValue which is in fact the same as PdhGetFormattedCounterValue i think.

jenkins, test it |
This PR adds functions to calculate performance counters from raw values. These functions should serve more as internal apis. For example needed here #3798. For using these functions see the added test.
