DXGK_VIDPNSOURCEMODESET_INTERFACE::pfnAcquireNextModeInfo routine

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

Syntax


DXGKDDI_VIDPNSOURCEMODESET_ACQUIRENEXTMODEINFO pfnAcquireNextModeInfo;

NTSTATUS APIENTRY pfnAcquireNextModeInfo(
  _In_  const D3DKMDT_HVIDPNSOURCEMODESET     hVidPnSourceModeSet,
  _In_  const D3DKMDT_VIDPN_SOURCE_MODE CONST *pVidPnSourceModeInfo,
  _Out_ const D3DKMDT_VIDPN_SOURCE_MODE       **ppNextVidPnSourceModeInfo
)
{ ... }

Parameters

hVidPnSourceModeSet [in]

[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]

[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]

[out] A pointer to a variable that receives a pointer to a D3DKMDT_VIDPN_SOURCE_MODE structure that describes the next mode.

Return value

The pfnAcquireNextModeInfo function returns one of the following values:

Return codeDescription
STATUS_SUCCESS

The function succeeded.

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.

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.
