A handle to the device.

`hContext`

A handle to the device context.

`BroadcastContextCount`

Specifies the number of contexts.

`BroadcastContext`

A D3DKMT_HANDLE data type that represents the broadcast context.

`VidPnSourceId`

The zero-based identification number of the video present source in a path of a video present network (VidPN) topology that the monitor is connected to.

`PresentCount`

The number of present operations that can be queued for the device that is specified by hDevice.

`FlipInterval`

A UINT value that specifies whether the display miniport driver natively supports the scheduling of a flip command to take effect after two, three or four vertical syncs occur.

`Flags`

Flag options.

`PresentPlaneCount`

The number of resources to pin.

`pPresentPlanes`
