  • Article

The VMEMHEAP structure contains information about the heap.

Syntax

typedef struct _VMEMHEAP {
  DWORD         dwFlags;
  DWORD         stride;
  LPVOID        freeList;
  LPVOID        allocList;
  DWORD         dwTotalSize;
  FLATPTR       fpGARTLin;
  FLATPTR       fpGARTDev;
  DWORD         dwCommitedSize;
  DWORD         dwCoalesceCount;
  HEAPALIGNMENT Alignment;
  DDSCAPSEX     ddsCapsEx;
  DDSCAPSEX     ddsCapsExAlt;
  LARGE_INTEGER liPhysAGPBase;
  HANDLE        hdevAGP;
  LPVOID        pvPhysRsrv;
  BYTE          *pAgpCommitMask;
  DWORD         dwAgpCommitMaskSize;
