PROCESS_MEMORY_COUNTERS structure (psapi.h)

Contains the memory statistics for a process.

typedef struct _PROCESS_MEMORY_COUNTERS {
  DWORD  cb;
  DWORD  PageFaultCount;
  SIZE_T PeakWorkingSetSize;
  SIZE_T WorkingSetSize;
  SIZE_T QuotaPeakPagedPoolUsage;
  SIZE_T QuotaPagedPoolUsage;

} PROCESS_MEMORY_COUNTERS;

cb

The size of the structure, in bytes.

PageFaultCount

The number of page faults.

PeakWorkingSetSize

The peak working set size, in bytes.

WorkingSetSize

The current working set size, in bytes.

QuotaPeakPagedPoolUsage

The peak paged pool usage, in bytes.

QuotaPagedPoolUsage

The current paged pool usage, in bytes.

QuotaPeakNonPagedPoolUsage

The peak nonpaged pool usage, in bytes.

QuotaNonPagedPoolUsage

The current nonpaged pool usage, in bytes.

PagefileUsage

The Commit Charge value in bytes for this process. Commit Charge is the total amount of memory that the memory manager has committed for a running process.

PeakPagefileUsage

The peak value in bytes of the Commit Charge during the lifetime of this process.
