Syntax

DXGKDDI_MONITORSOURCEMODESET_ACQUIREFIRSTMODEINFO DxgkddiMonitorsourcemodesetAcquirefirstmodeinfo;

NTSTATUS DxgkddiMonitorsourcemodesetAcquirefirstmodeinfo(
  IN_CONST_D3DKMDT_HMONITORSOURCEMODESET hMonitorSourceModeSet,
  DEREF_OUT_CONST_PPD3DKMDT_MONITOR_SOURCE_MODE ppFirstMonitorSourceModeInfo
)
{...}

Parameters

hMonitorSourceModeSet

[in] 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.

ppFirstMonitorSourceModeInfo

[out] 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 code Description
STATUS_SUCCESS The function succeeded.

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.
