PdhVbGetDoubleCounterValue function
The PdhVbGetDoubleCounterValue function returns the current value of the specified counter as a double-precision floating point value. You should check CounterStatus before using the returned number, because the counter may not be valid when it is read. To check the counter status, call the PdhVbIsGoodStatus function.
