The DD_GETFLIPSTATUSDATA structure is passed to the DirectDraw hardware interface’s GetFlipStatus surface object callback.
Members
lpDD
Pointer to the DD_DIRECTDRAW_GLOBAL structure that describes the driver.
lpDDSurface
Pointer to the DD_SURFACE_LOCAL structure that describes the surface on which the flip status query should be made.
dwFlags
Flag that tells the driver what information is being requested about the flip. The DDGFS_Xxx bit fields, enumerated in ddraw.h, are:
Value | Meaning |
DDGFS_CANFLIP | Driver should determine whether it can perform a flip at this time. |
DDGFS_ISFLIPDONE | Driver should determine whether an initiated flip has completed. |
ddRVal
Location in which the driver returns a DirectDraw status return code. The status codes are defined in ddraw.h.
