Thanks Pavel,

No, this is different.

I am a little confused. You mean this API provides commit change value if we
retrieve page file value from the dwAvailPhys member of MEMORYSTATUS?

I want to confirm with you about the term commit charge. It means actual
consumed RAM (physical memory) + paging file (disk), right?


regards,
George

Do you mean the demand for zero case? :-)

Yes, demand-zero pages.

"Paging File\% Usage" perf counter can be used for this.

There is another way.

No, this is different.

In almost all cases if you see "page file" in the name of some counter
you can substitute it with "commit charge". ullAvailPageFile is just
another example.

Paging File\% Usage on the other hand represents the actual amount
of data in the pagefile. It's a rarely used counter, and as far as I know
there is no other documented way to access it.
