DXGKDDI_VIDPNSOURCEMODESET_RELEASEMODEINFO callback function (d3dkmddi.h)
The pfnReleaseModeInfo function releases a D3DKMDT_VIDPN_SOURCE_MODE structure that the VidPN manager previously provided to the display miniport driver.
Syntax
DXGKDDI_VIDPNSOURCEMODESET_RELEASEMODEINFO DxgkddiVidpnsourcemodesetReleasemodeinfo;
NTSTATUS DxgkddiVidpnsourcemodesetReleasemodeinfo(
[in] IN_CONST_D3DKMDT_HVIDPNSOURCEMODESET hVidPnSourceModeSet,
[in] IN_CONST_PD3DKMDT_VIDPN_SOURCE_MODE_CONST pVidPnSourceModeInfo
)
{...}
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] pVidPnSourceModeInfo
A pointer to the D3DKMDT_VIDPN_SOURCE_MODE structure that is to be released.
Return value
The pfnReleaseModeInfo 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 pointer supplied in pVidPnSourceModeInfo was invalid. |
Remarks
When you have finished using a D3DKMDT_VIDPN_SOURCE_MODE structure that you obtained by calling any of the following functions, you must release the structure by calling pfnReleaseModeInfo.
If you obtain a D3DKMDT_VIDPN_SOURCE_MODE structure by calling pfnCreateNewModeInfo and then pass that structure to pfnAddMode, you do not need to release the structure.If you obtain a handle by calling pfnCreateNewModeInfo and then you decide not to add the new mode to a source mode set, you must release the newly created structure by calling pfnReleaseModeInfo.
The D3DKMDT_HVIDPNSOURCEMODESET data type is defined in D3dkmdt.h.
