DXGKDDI_VIDPNSOURCEMODESET_ACQUIREPINNEDMODEINFO callback function

Description

The pfnAcquirePinnedModeInfo function returns a descriptor of the pinned mode in a specified VidPN source mode set.

Parameters

hVidPnSourceModeSet [in]

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.

ppPinnedVidPnSourceModeInfo [out]

A pointer to a variable that receives a pointer to a D3DKMDT_VIDPN_SOURCE_MODE structure. The structure contains a variety of information about the pinned mode, including its ID, type, and rendering format. If the source mode set identified by hVidPnSourceModeSet has no pinned mode, then this variable receives a NULL pointer.

Return value

The pfnAcquirePinnedModeInfo function returns one of the following values:

Return code Description
STATUS_SUCCESS The function succeeded by doing one of the following:
1. Setting ppPinnedVidPnSourceModeInfo to the address of D3DKMDT_VIDPN_SOURCE_MODE structure that describes the pinned mode.
2. Setting ppPinnedVidPnSourceModeInfo to NULL to indicate that the source mode set has no pinned mode.
STATUS_GRAPHICS_INVALID_VIDPN_SOURCEMODESET The handle supplied in hVidPnSourceModeSet was invalid.

Remarks

When you have finished using the D3DKMDT_VIDPN_SOURCE_MODE structure, you must release the structure by calling pfnReleaseModeInfo.

The D3DKMDT_HVIDPNSOURCEMODESET data type is defined in D3dkmdt.h.
