Description

The DXGKARG_CANCELFLIPS structure contains parameters for the driver's DXGKDDI_CANCELFLIPS callback function.

Members

`VidPnSourceId`

[in] A D3DDDI_VIDEO_PRESENT_SOURCE_ID value that identifies the VidPn source ID of the flip queue.

`PlaneCount`

[in] Number of planes with pending Presents to cancel; that is, the number of DXGK_CANCELFLIPS_PLANE structures in the array that ppPlanes points to.

`ppPlanes`

[in/out] Pointer to an array of DXGK_CANCELFLIPS_PLANE structures, each containing a per plane cancel request.

Remarks

Asynchronously cancelled PresentIds are reported via the VSync interrupt mechanism.

See Cancelling interlocked flips on multiple planes for more information.
