Private working set

To calculate this quantity, not present in PROCESS_MEMORY_COUNTERS_EX, call QueryWorkingSet() to read all the page entries into a buffer. Then count the number of entries where PSAPI_WORKING_SET_INFORMATION::WorkingSetInfo[nI].Shared is false. Multiply that by the bytes-per-page size (SYSTEM_INFO::dwPageSize) using GetSystemInfo() to get the total private working set (which is not the same as the committed private bytes PrivateUsage.

What would be the code implementation?
