The CONST_DDGFSFLAGS enumeration is used by the flags parameter of the DirectDrawSurface7.GetFlipStatus method to specify the type of flip status to obtain.
Enum CONST_DDGFSFLAGS
DDGFS_CANFLIP = 1
DDGFS_ISFLIPDONE = 2
End Enum
DDGFS_CANFLIP

DDGFS_ISFLIPDONE
Inquires whether the flip has finished, and returns DD_OK if the last flip on this surface has completed.
