Syntax

DXGKDDI_MONITORSOURCEMODESET_ACQUIREFIRSTMODEINFO DxgkddiMonitorsourcemodesetAcquirefirstmodeinfo;

NTSTATUS DxgkddiMonitorsourcemodesetAcquirefirstmodeinfo(
  [in]  IN_CONST_D3DKMDT_HMONITORSOURCEMODESET hMonitorSourceModeSet,
  [out] DEREF_OUT_CONST_PPD3DKMDT_MONITOR_SOURCE_MODE ppFirstMonitorSourceModeInfo
)
{...}

Parameters

[in] hMonitorSourceModeSet

A handle to a monitor source mode set object. The display miniport driver previously obtained this handle by calling the pfnAcquireMonitorSourceModeSet function of the Monitor interface.

[out] ppFirstMonitorSourceModeInfo

A pointer to a variable that receives a pointer to a D3DKMDT_MONITOR_SOURCE_MODE structure. The structure contains a variety of information about the monitor source mode, including its ID and video signal characteristics.

Return value

The pfnAcquireFirstModeInfo function returns one of the following values:

Return code Description
STATUS_SUCCESS The function succeeded.
STATUS_GRAPHICS_INVALID_MONITOR_SOURCEMODESET The handle supplied in hMonitorSourceModeSet was invalid.

Remarks

When you have finished using the D3DKMDT_MONITOR_SOURCE_MODE structure, you must release the structure by calling pfnReleaseModeInfo.

You can enumerate all the modes that belong to a VidPN monitor source mode set object by calling pfnAcquireFirstModeInfo and then making a sequence of calls to pfnAcquireNextModeInfo.

The D3DKMDT_HMONITORSOURCEMODESET data type is defined in D3dkmdt.h.
