DXGKDDI_CANCELQUEUEDFLIPS callback function (d3dkmddi.h)
In the hardware flip queue model, the OS calls a display miniport driver's DXGKDDI_CANCELQUEUEDFLIPS function to synchronously cancel previously queued flips. This function was superseded by DXGKDDI_CANCELFLIPS starting in WDDM 3.0.
Syntax
DXGKDDI_CANCELQUEUEDFLIPS DxgkddiCancelqueuedflips;
NTSTATUS DxgkddiCancelqueuedflips(
IN_CONST_HANDLE hAdapter,
INOUT_PDXGKARG_CANCELQUEUEDFLIPS pCancelQueuedFlips
)
{...}
Parameters
hAdapter
[in] Handle to a display adapter.
pCancelQueuedFlips
[in/out] Pointer to a DXGKARG_CANCELQUEUEDFLIPS structure containing the parameters for this function.
Return value
DXGKDDI_CANCELQUEUEDFLIPS returns STATUS_SUCCESS. The driver should always return a success code.
Remarks
Asynchronously cancelled PresentIds are reported via the VSync interrupt mechanism.
