The pfnReleaseSourceModeSet function releases a handle to a source mode set object.
hVidPn [in]A handle to the VidPN object that contains the source mode set object. The VidPN manager previously provided this handle to the display miniport driver by calling DxgkDdiEnumVidPnCofuncModality, DxgkDdiIsSupportedVidPn, or DxgkDdiRecommendFunctionalVidPn.
hVidPnSourceModeSet [in]The handle to be released.
The pfnReleaseSourceModeSet function returns one of the following values:
| Return code | Description |
|---|---|
| STATUS_SUCCESS | The function succeeded. |
| STATUS_GRAPHICS_INVALID_VIDPN | The handle supplied in hVidPn was invalid. |
| STATUS_GRAPHICS_INVALID_VIDPN_SOURCEMODESET | The handle supplied in hVidPnSourceModeSet was invalid. |
| STATUS_GRAPHICS_RESOURCES_NOT_RELATED | The VidPN identified by hVidPn does not contain the source mode set identified by hVidPnSourceModeSet. |
When you have finished using a handle that you obtained by calling pfnAcquireSourceModeSet, you must release the handle by calling pfnReleaseSourceModeSet.
If you obtain a handle by calling pfnCreateNewSourceModeSet and then pass that handle to pfnAssignSourceModeSet, you do not need to release the handle.
If you obtain a handle by calling pfnCreateNewSourceModeSet and then you decide not to assign the new source mode set to a source, you must release the newly obtained handle by calling pfnReleaseSourceModeSet.
The D3DKMDT_HVIDPN and D3DKMDT_HVIDPNSOURCEMODESET data types are defined in D3dkmdt.h.
