This data structure is identical to VRAMALLOCOUT structure except that it contains an additional field for the optional pointer to a system memory buffer and an expanded definition of the ulFlags field. The expanded definition indicates if a system memory buffer has been allocated instead of a VRAM buffer.

typedef struct _VRAMALLOCOUT2 {
  ULONG     ulLength;           /* length of this structure         */
  ULONG     ulFlags;            /* Returned flag work buffer        */
  ULONG     ulID;               /* Buffer ID                        */
  POINTL    ptlStart;           /* X and Y point offset into VRAM   */
  ULONG     ulSize;             /* Byte size allocated              */
  ULONG     ulScanLineBytes;    /* Number of bytes per scan line    */
  PVOID     pNewBuffer;         /* 32-bit linear ptr to new buffer  */
} VRAMALLOCOUT2;
