PROCESS_MEMORY_COUNTERS_EX structure (psapi.h)
Contains extended memory statistics for a process.
Syntax
typedef struct _PROCESS_MEMORY_COUNTERS_EX {
DWORD cb;
DWORD PageFaultCount;
SIZE_T PeakWorkingSetSize;
SIZE_T WorkingSetSize;
SIZE_T QuotaPeakPagedPoolUsage;
SIZE_T QuotaPagedPoolUsage;
SIZE_T QuotaPeakNonPagedPoolUsage;
SIZE_T QuotaNonPagedPoolUsage;
SIZE_T PagefileUsage;
SIZE_T PeakPagefileUsage;
SIZE_T PrivateUsage;
} PROCESS_MEMORY_COUNTERS_EX;
Members
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 private memory that the memory manager has committed for a running process.
Windows 7 and Windows Server 2008 R2 and earlier: PagefileUsage is always zero. Check PrivateUsage instead.
PeakPagefileUsage
The peak value in bytes of the Commit Charge during the lifetime of this process.
PrivateUsage
Same as PagefileUsage. The Commit Charge value in bytes for this process. Commit Charge is the total amount of private memory that the memory manager has committed for a running process.
