The pfnReleaseTargetModeSet function releases a handle to a target mode set object.
Syntax
DXGKDDI_VIDPN_RELEASETARGETMODESET DxgkddiVidpnReleasetargetmodeset;
NTSTATUS DxgkddiVidpnReleasetargetmodeset(
[in] IN_CONST_D3DKMDT_HVIDPN hVidPn,
[in] IN_CONST_D3DKMDT_HVIDPNTARGETMODESET hVidPnTargetModeSet
)
{...}
Parameters
[in] hVidPn
A handle to a VidPN object that contains the target mode set object. The VidPN manager previously provided this handle to the display miniport driver by calling DxgkDdiEnumVidPnCofuncModality, DxgkDdiIsSupportedVidPn, or DxgkDdiRecommendFunctionalVidPn.
[in] hVidPnTargetModeSet
The handle to be released.
Return value
The pfnReleaseTargetModeSet 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_TARGETMODESET | The handle supplied in hVidPnTargetModeSet was invalid. |
| STATUS_GRAPHICS_RESOURCES_NOT_RELATED | The VidPN identified by hVidPn does not contain the target mode set identified by hVidPnTargetModeSet. |
Remarks
When you have finished using a handle that you obtained by calling pfnAcquireTargetModeSet, you must release the handle by calling pfnReleaseTargetModeSet.
If you obtain a handle by calling pfnCreateNewTargetModeSet and then pass that handle to pfnAssignTargetModeSet, you do not need to release the handle.
If you obtain a handle by calling pfnCreateNewTargetModeSet and then you decide not to assign the new source mode set to a source, you must release the newly obtained handle by calling pfnReleaseTargetModeSet.
The D3DKMDT_HVIDPN and D3DKMDT_HVIDPNTARGETMODESET data types are defined in D3dkmdt.h.
