DD_FREEDRIVERMEMORYDATA structure (ddrawint.h)
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.
