The pfnAcquireFirstModeInfo function returns a descriptor of the first mode in a specified VidPN target mode set.

Syntax


DXGKDDI_VIDPNTARGETMODESET_ACQUIREFIRSTMODEINFO pfnAcquireFirstModeInfo;

NTSTATUS APIENTRY pfnAcquireFirstModeInfo(
  _In_   const D3DKMDT_HVIDPNTARGETMODESET hVidPnTargetModeSet,
  _Out_  const D3DKMDT_VIDPN_TARGET_MODE **ppFirstVidPnTargetModeInfo
)
{ ... }

Parameters

hVidPnTargetModeSet [in]

[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]

[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.

Return codeDescription
STATUS_SUCCESS

STATUS_GRAPHICS_INVALID_VIDPN_TARGETMODESET

The handle supplied in hVidPnTargetModeSet was invalid.

 

Remarks

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.
