Fields

PageInCount: Specifies the number of pages that have been swapped into physical memory.
PageOutCount: Specifies the number of pages that have been swapped out of physical memory.
SwapResvCount: Specifies the number of pages that are reserved within the swap files.
SwapPageCount: Specifies the number of swap pages currently in use.
SwapFreeCount: Specifies the number of swap pages currently free.
PageFaultCount: Specifies the number of times a page was not currently in physical memory and had to be swapped in for a process to continue.
freeCachePages: Specifies the number of swapped pages that are waiting in cache to be written to disk.
freeCleanPages: Specifies the number of pages that are free and have been cleared of all old data.
freeDirtyPages: Specifies the number of pages that are free but still retain old data.
VMPhysicalPageCount: Specifies the total number of pages allocated for virtual memory.
reserved: Reserved for future use.

Remarks

Since the fields in this structure are long long (or 64-bit), use the ll length modifier with printf-type functions to display the values. For example:

  printf("Page In Count:     %lld\n"
