The pfnAcquireNextModeInfo function returns a descriptor of the next mode in a specified VidPN source mode set, given the current mode.
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.
pVidPnSourceModeInfo [in]A pointer to a D3DKMDT_VIDPN_SOURCE_MODE structure that describes the current mode. The display miniport driver previously obtained this pointer by calling pfnAcquireFirstModeInfo or pfnAcquireNextModeInfo.
ppNextVidPnSourceModeInfo [out]A pointer to a variable that receives a pointer to a D3DKMDT_VIDPN_SOURCE_MODE structure that describes the next mode.
The pfnAcquireNextModeInfo 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. |
When you have finished using the D3DKMDT_VIDPN_SOURCE_MODE structure, you must release the structure by calling pfnReleaseModeInfo.
You can enumerate all the modes that belong to a VidPN source mode set object by calling pfnAcquireFirstModeInfo and then making a sequence of calls to pfnAcquireNextModeInfo.
The D3DKMDT_HVIDPNSOURCEMODESET data type is defined in D3dkmdt.h.
