DXGKDDI_VIDPNTARGETMODESET_ACQUIRENEXTMODEINFO callback function (d3dkmddi.h)

The pfnAcquireNextModeInfo function returns a descriptor of the next mode in a specified VidPN target mode set, given the current mode.

Syntax

DXGKDDI_VIDPNTARGETMODESET_ACQUIRENEXTMODEINFO DxgkddiVidpntargetmodesetAcquirenextmodeinfo;

NTSTATUS DxgkddiVidpntargetmodesetAcquirenextmodeinfo(
  [in]  IN_CONST_D3DKMDT_HVIDPNTARGETMODESET hVidPnTargetModeSet,
  [in]  IN_CONST_PD3DKMDT_VIDPN_TARGET_MODE_CONST pVidPnTargetModeInfo,
  [out] DEREF_OUT_CONST_PPD3DKMDT_VIDPN_TARGET_MODE ppNextVidPnTargetModeInfo
)
{...}

Parameters

[in] hVidPnTargetModeSet

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.

[in] pVidPnTargetModeInfo

A pointer to a D3DKMDT_VIDPN_TARGET_MODE structure that describes the current mode. The display miniport driver previously obtained this pointer by calling pfnAcquireFirstModeInfo or pfnAcquireNextModeInfo.

[out] ppNextVidPnTargetModeInfo

A pointer to a variable that receives a pointer to a D3DKMDT_VIDPN_TARGET_MODE structure that describes the next mode.

Return value

The pfnAcquireNextModeInfo function returns one of the following values:

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 particular target mode set object by calling pfnAcquireFirstModeInfo and then making a sequence of calls to pfnAcquireNextModeInfo.

The D3DKMDT_HVIDPNTARGETMODESET data type is defined in D3dkmdt.h.
