in reply to Help on Win32::Perflib

According to this, the PERF_COUNTER_MULTI_BASE is the base required for calculations involving ERF_100NSEC_MULTI_TIMER_INV.

Ie. B = the value of PERF_COUNTER_MULTI_BASE.

However, the calculation shown here is somewhat different to the formula you have.

    BrowserUk,
    Thanks for your attention, I read on MS site about PERF_COUNTER_MULTI_BASE but I didn't understand how they works, how to get it, and I found no examples.
    Because this I moved to the next counter (PERF_RAW_FRACTION) and I could undestand that this base value are on same Perflib hash, I just have to continue looking for a BASE counter type. For example, I must to get the counter value of a PERF_RAW_FRACTION, then get the counter value of PERF_RAW_BASE (of course of same perf counter), and finally do the calculation. It's should be easier, but it's not !!! discovery that they work like PERF_100NSEC_MULTI_TIMER_INV. It's need a base too and discovery that I must
