GetPhysicalMonitorsFromIDirect3DDevice9 function (physicalmonitorenumerationapi.h)

Retrieves the physical monitors associated with a Direct3D device.

Syntax

HRESULT GetPhysicalMonitorsFromIDirect3DDevice9(
  [in]  IDirect3DDevice9   *pDirect3DDevice9,
  [in]  DWORD              dwPhysicalMonitorArraySize,
  [out] LPPHYSICAL_MONITOR pPhysicalMonitorArray
);

Parameters

[in] pDirect3DDevice9

Pointer to the IDirect3DDevice9 interface of the Direct3D device.

[in] dwPhysicalMonitorArraySize

Number of elements in pPhysicalMonitorArray. To get the required size of the array, call GetNumberOfPhysicalMonitorsFromIDirect3DDevice9.

[out] pPhysicalMonitorArray

Pointer to an array of PHYSICAL_MONITOR structures. The caller must allocate the array.

Return value

If this function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

A single Direct3D device can be associated with more than one physical monitor. This function returns a handle and a text description for each physical monitor.

When you are done using the monitor handles, close them by passing the pPhysicalMonitorArray array to the DestroyPhysicalMonitors function.
