This structure contains data about the state of the loader page pool or the file page pool. It is used in conjunction with the NKPagePoolState structure and the IOCTL_KLIB_GET_POOL_STATE I/O control.

Syntax

typedef struct {
    DWORD CurrentSize;
    DWORD TrimCount;
    DWORD TrimTime;
    DWORD CriticalCount;
    DWORD CriticalTime;
    DWORD FailCount;
} PagePoolState;

Members

• CurrentSize
  Amount of memory, in bytes, currently in use by the pool.

• TrimCount
  Number of times the target was exceeded and the trimming thread ran.

• TrimTime
  Amount of time, in milliseconds, that the trimming thread has run.

• CriticalCount
