The DemandInfoStruc structure contains information about pages that are subject to demand paging. The _GetDemandPageInfo service fills in the members of this structure.

DIPhys_Count

Specifies the total number of physical pages managed by the memory manager.

DIFree_Count

Specifies the number of pages currently in the free pool.

DIUnlock_Count

Specifies the number of pages that are currently unlocked. Free pages are always unlocked.

DILin_Total_Free

Total number of free virtual pages in the current memory context. This value includes only pages in the private arena, the linear address range controlled by the memory context services.

DIPagingFileMax

Current maximum size of the swap file, in pages. This member is zero if swapping is turned off.

DIPagingFileInUse

Number of swap file pages currently in use. This value reflects the number of pages by which physical memory is overcommitted. It is zero if swapping is turned off or if physical memory is available for all swappable pages.
