GetPhysicalMonitorsFromIDirect3DDevice9 function

-description

Retrieves the physical monitors associated with a Direct3D device.

-parameters

-param pDirect3DDevice9 [in]

Pointer to the IDirect3DDevice9 interface of the Direct3D device.

-param dwPhysicalMonitorArraySize [in]

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

-param pPhysicalMonitorArray [out]

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

-returns

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.
