GetFlipStatus

DWORD GetFlipStatus(
    PDD_GETFLIPSTATUSDATA  lpGetFlipStatus
);

GetFlipStatus queries the driver for its flip status.

Parameters

lpGetFlipStatus

Pointer to a DD_GETFLIPSTATUSDATA structure that contains the information required to perform the flip status query.

Return Value

GetFlipStatus returns a DDHAL_DRIVER_Xxx callback code that indicates how the driver handled the call. These return codes are defined in ddrawint.h.

Comments

The driver should report its flip status based on the flag set in the dwFlags member of lpGetFlipStatus. If the driver is busy and cannot otherwise perform a flip at this time, it should set the ddRVal member to DDERR_WASSTILLDRAWING; otherwise, the driver should set ddRVal to DD_OK.
