D3DKMT_SETVIDPNSOURCEOWNER structure (d3dkmthk.h)
The D3DKMT_SETVIDPNSOURCEOWNER structure describes the parameters for setting or releasing the video present source in the path of a video present network (VidPN) topology that owns the VidPN.
Syntax
typedef struct _D3DKMT_SETVIDPNSOURCEOWNER {
[in] D3DKMT_HANDLE hDevice;
[in] const D3DKMT_VIDPNSOURCEOWNER_TYPE *pType;
[in] const D3DDDI_VIDEO_PRESENT_SOURCE_ID *pVidPnSourceId;
UINT VidPnSourceCount;
} D3DKMT_SETVIDPNSOURCEOWNER;
Members
[in] hDevice
A D3DKMT_HANDLE data type that represents a kernel-mode handle to the device that acquires or releases the VidPN source owner.
[in] pType
An array of owner types. Elements of the array can contain the following values from the D3DKMT_VIDPNSOURCEOWNER_TYPE enumeration type.
| Value | Meaning |
|---|---|
| D3DKMT_VIDPNSOURCEOWNER_UNOWNED (0) | No owner, or GDI is the owner. |
| D3DKMT_VIDPNSOURCEOWNER_SHARED (1) | A shared owner. That is, the owner can yield to any exclusive owner. This type is not available to legacy devices. |
| D3DKMT_VIDPNSOURCEOWNER_EXCLUSIVE (2) | An exclusive owner without shared GDI primary. |
| D3DKMT_VIDPNSOURCEOWNER_EXCLUSIVEGDI (3) | An exclusive owner with shared GDI primary. This owner must exclusively own all of the VidPn sources. This type is available only to legacy devices. |
[in] pVidPnSourceId
An array of zero-based identification numbers of the video present sources in paths of a video present network (VidPN) topology.
VidPnSourceCount
The number of valid entries in the array that pVidPnSourceId specifies.
