DXGKDDI_VIDPNSOURCEMODESET_PINMODE callback function (d3dkmddi.h)
The pfnPinMode function pins a specified mode in a VidPN source mode set.
Syntax
DXGKDDI_VIDPNSOURCEMODESET_PINMODE DxgkddiVidpnsourcemodesetPinmode;
NTSTATUS DxgkddiVidpnsourcemodesetPinmode(
[in] IN_D3DKMDT_HVIDPNSOURCEMODESET hVidPnSourceModeSet,
[in] IN_CONST_D3DKMDT_VIDEO_PRESENT_SOURCE_MODE_ID VidPnSourceModeId
)
{...}
Parameters
[in] hVidPnSourceModeSet
A handle to a VidPN source mode set object. The display miniport driver previously obtained this handle by calling the pfnAcquireSourceModeSet function of the DXGK_VIDPN_INTERFACE interface.
[in] VidPnSourceModeId
An integer that identifies the mode to be pinned.
Return value
The pfnPinMode function returns one of the following values:
Return code | Description |
---|---|
STATUS_SUCCESS | The function succeeded. |
STATUS_GRAPHICS_INVALID_VIDPN_SOURCEMODESET | The handle supplied in hVidPnSourceModeSet was invalid. |
STATUS_GRAPHICS_INVALID_VIDEO_PRESENT_SOURCE_MODE | The mode identified by VidPnSourceModeId does not belong to the source mode set represented by hVidPnSourceModeSet. |
Remarks
VidPN source mode identifiers are assigned by the operating system. The pfnCreateNewModeInfo function generates a mode identifier, assigns the identifier to the Id member of a D3DKMDT_VIDPN_SOURCE_MODE structure, and returns the structure to the display miniport driver.
The D3DKMDT_HVIDPNSOURCEMODESET data type is defined in D3dkmdt.h.
