  • Article

The DD_FREEDRIVERMEMORYDATA structure contains the details of the free request.

Syntax

typedef struct _DD_FREEDRIVERMEMORYDATA {
  PDD_DIRECTDRAW_GLOBAL lpDD;
  PDD_SURFACE_LOCAL     lpDDSurface;
  HRESULT               ddRVal;
  VOID                  *FreeDriverMemory;
} *PDD_FREEDRIVERMEMORYDATA, DD_FREEDRIVERMEMORYDATA;

Members

lpDD

Points to the DD_DIRECTDRAW_GLOBAL structure that describes the driver's device.

lpDDSurface

Points to the DD_SURFACE_LOCAL structure representing the surface that Microsoft DirectDraw is attempting to allocate.

ddRVal

Specifies the location in which the driver writes the return value of the DdFreeDriverMemory callback. A return code of DD_OK indicates that the driver succeeded in freeing some space; otherwise, the driver should set this to be DDERR_OUTOFMEMORY. For more information, see Return Values for DirectDraw.

FreeDriverMemory

Used by the DirectDraw API and should not be filled in by the driver.
