The pfnReleaseModeInfo function releases a D3DKMDT_MONITOR_SOURCE_MODE structure that the VidPN manager previously provided to the display miniport driver.

Syntax

DXGKDDI_MONITORSOURCEMODESET_RELEASEMODEINFO DxgkddiMonitorsourcemodesetReleasemodeinfo;

NTSTATUS DxgkddiMonitorsourcemodesetReleasemodeinfo(
  [in] IN_CONST_D3DKMDT_HMONITORSOURCEMODESET hMonitorSourceModeSet,
  [in] IN_CONST_PD3DKMDT_MONITOR_SOURCE_MODE_CONST pMonitorSourceModeInfo
)
{...}

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.

[in] pMonitorSourceModeInfo

A pointer to the D3DKMDT_MONITOR_SOURCE_MODE structure that is to be released.

Return value

The pfnReleaseModeInfo 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.
STATUS_GRAPHICS_INVALID_VIDEO_PRESENT_TARGET_MODE	The pointer supplied in pMonitorSourceModeInfo was invalid.

Remarks

When you have finished using a D3DKMDT_MONITOR_SOURCE_MODE structure that you obtained by calling pfnAcquireFirstModeInfo or pfnAcquireNextModeInfo, you must release the structure by calling pfnReleaseModeInfo.

The D3DKMDT_HMONITORSOURCEMODESET data type is defined in D3dkmdt.h.
