DXGKDDI_CANCELFLIPS callback function (d3dkmddi.h)

In the hardware flip queue model, the OS calls a display miniport driver's DXGKDDI_CANCELFLIPS function to synchronously cancel previously queued flips.

Syntax

DXGKDDI_CANCELFLIPS DxgkddiCancelflips;

NTSTATUS DxgkddiCancelflips(
  IN_CONST_HANDLE hAdapter,
  INOUT_PDXGKARG_CANCELFLIPS pCancelFlips
)
{...}

Parameters

hAdapter

[in] Handle to a display adapter.

pCancelFlips

[in/out] Pointer to a DXGKARG_CANCELFLIPS structure containing the parameters for this function.

Return value

DXGKDDI_CANCELFLIPS returns an NTSTATUS code such as one of the following:

Return value	Meaning
STATUS_SUCCESS	The routine completed successfully.
STATUS_NOT_IMPLEMENTED	The driver does not implement support for this operation. For this return status, the OS will follow up with a call to DxgkDdiCancelQueuedFlips.

Remarks

Asynchronously cancelled PresentIds are reported via the VSync interrupt mechanism.

See Cancelling interlocked flips on multiple planes for more information.
