The pfnAcquireFirstModeInfo function returns a descriptor of the first mode in a specified VidPN target mode set.
hVidPnTargetModeSet [in]A handle to a VidPN target mode set object. The display miniport driver previously obtained this handle by calling the pfnAcquireTargetModeSet function of the DXGK_VIDPN_INTERFACE interface.
ppFirstVidPnTargetModeInfo [out]A pointer to a variable that receives a pointer to a D3DKMDT_VIDPN_TARGET_MODE structure. The structure contains a variety of information about the target mode, including its ID and video signal characteristics.
The pfnAcquireFirstModeInfo function returns one of the following values:
| Return code | Description |
|---|---|
| STATUS_SUCCESS | The function succeeded. |
| STATUS_GRAPHICS_INVALID_VIDPN_TARGETMODESET | The handle supplied in hVidPnTargetModeSet was invalid. |
When you have finished using the D3DKMDT_VIDPN_TARGET_MODE structure, you must release the structure by calling pfnReleaseModeInfo.
You can enumerate all the modes that belong to a VidPN target mode set object by calling pfnAcquireFirstModeInfo and then making a sequence of calls to pfnAcquireNextModeInfo.
