D3D10CreateDevice function (d3d10misc.h)

Create a Direct3D 10.0 device that represents the display adapter.

Syntax

HRESULT D3D10CreateDevice(
  [in]  IDXGIAdapter      *pAdapter,
  [in]  D3D10_DRIVER_TYPE DriverType,
  [in]  HMODULE           Software,
  [in]  UINT              Flags,
  [in]  UINT              SDKVersion,
  [out] ID3D10Device      **ppDevice
);

Parameters

[in] pAdapter

Type: IDXGIAdapter*

Pointer to the display adapter (see IDXGIAdapter) when creating a hardware device; otherwise set this parameter to NULL. If NULL is specified when creating a hardware device, Direct3D will use the first adapter enumerated by EnumAdapters.

[in] DriverType

Type: D3D10_DRIVER_TYPE

The device-driver type (see D3D10_DRIVER_TYPE). The driver type determines the type of device you will create.

[in] Software

Type: HMODULE

Reserved. Set to NULL.

[in] Flags

Type: UINT

Optional. Device creation flags (see D3D10_CREATE_DEVICE_FLAG) that enable API layers. These flags can be bitwise OR'd together.

[in] SDKVersion

Type: UINT

Bit flag that indicates the version of the SDK. Should always be D3D10_SDK_VERSION.

[out] ppDevice

Type: ID3D10Device**

Address of a pointer to the device created (see ID3D10Device Interface).

Return value

Type: HRESULT

This method returns one of the following Direct3D 10 Return Codes.

Remarks

This example creates a reference device.

ID3D10Device* g_pd3dDevice = NULL;
D3D10CreateDevice( NULL, D3D10_DRIVER_TYPE_REFERENCE, NULL, 0, 
    D3D10_SDK_VERSION, &g_pd3dDevice );             
      

To create a device and a swap chain at the same time, see D3D10CreateDeviceAndSwapChain.

The object returned by D3D10CreateDevice implements the IUnknown interface and can be queried for other interfaces the object supports. To retrieve the IDXGIDevice interface of the object the following code could be used.

IDXGIDevice * pDXGIDevice;
hr = g_pd3dDevice->QueryInterface(__uuidof(IDXGIDevice), (void **)&pDXGIDevice);
