D3D11CreateDeviceAndSwapChain Function

Creates a device that represents the display adapter and a swap chain used for rendering.

Syntax

HRESULT D3D11CreateDeviceAndSwapChain(
  __in   IDXGIAdapter *pAdapter,
  __in   D3D_DRIVER_TYPE DriverType,
  __in   HMODULE Software,
  __in   UINT Flags,
  __in   const D3D_FEATURE_LEVEL *pFeatureLevels,
  __in   UINT FeatureLevels,

  __out  ID3D11DeviceContext **ppImmediateContext
);

Parameter

• pAdapter [in]
  Typ: IDXGIAdapter*

  A pointer to the video adapter to use when creating a device. Pass NULL to use the default adapter, which is the first adapter enumerated by IDXGIFactory1::EnumAdapters.

  Hinweis  Do not mix the use of DXGI 1.0 (IDXGIFactory) and DXGI 1.1 (IDXGIFactory1) in an application. Use IDXGIFactory or IDXGIFactory1, but not both in an application.

• DriverType [in]
  Typ: D3D_DRIVER_TYPE

  The D3D_DRIVER_TYPE, which represents the driver type to create.

• Software [in]
  Typ: HMODULE

  A handle to a DLL that implements a software rasterizer. If DriverType is D3D_DRIVER_TYPE_SOFTWARE, Software must not be NULL. Get the handle by calling LoadLibrary, LoadLibraryEx , or GetModuleHandle. The value should be non-NULL when D3D_DRIVER_TYPE is D3D_DRIVER_TYPE_SOFTWARE and NULL otherwise.

• Flags [in]
  Typ: UINT

  The runtime layers to enable (see D3D11_CREATE_DEVICE_FLAG); values can be bitwise OR'd together.

• pFeatureLevels [in]
  Typ: const D3D_FEATURE_LEVEL*

  A pointer to an array of D3D_FEATURE_LEVELs, which determine the order of feature levels to attempt to create. Use default parameters to get the greatest feature level available. If pFeatureLevels is set to NULL, the following array of feature levels will be used:

  
  {
      D3D_FEATURE_LEVEL_11_0,
      D3D_FEATURE_LEVEL_10_1,
      D3D_FEATURE_LEVEL_10_0,
      D3D_FEATURE_LEVEL_9_3,
      D3D_FEATURE_LEVEL_9_2,
      D3D_FEATURE_LEVEL_9_1,
  };
  
  

• FeatureLevels [in]
  Typ: UINT

  The number of elements in pFeatureLevels.

• SDKVersion [in]
  Typ: UINT

  The SDK version; use D3D11_SDK_VERSION.

• pSwapChainDesc [in]
  Typ: const DXGI_SWAP_CHAIN_DESC*

  A pointer to a swap chain description (see DXGI_SWAP_CHAIN_DESC) that contains initialization parameters for the swap chain.

• ppSwapChain [out]
  Typ: IDXGISwapChain**

  Returns the address of a pointer to the IDXGISwapChain object that represents the swap chain used for rendering.

• ppDevice [out]
  Typ: ID3D11Device**

  Returns the address of a pointer to an ID3D11Device object that represents the device created. Supply NULL as an input to return the highest supported feature level in pFeatureLevel.

• pFeatureLevel [out]
  Typ: D3D_FEATURE_LEVEL*

  Returns a pointer to a D3D_FEATURE_LEVEL, which represents the first element in an array of feature levels supported by the device.

• ppImmediateContext [out]
  Typ: ID3D11DeviceContext**

  Returns the address of a pointer to an ID3D11DeviceContext object that represents the device context.

Rückgabewert

Typ: HRESULT

This method returns one of the following Direct3D 11 Return Codes.

Hinweise

This entry-point is supported by the Direct3D 11 runtime, which is available on Windows 7, Windows Server 2008 R2, and as an update to Windows Vista (KB971644).

Also, see the remarks section in D3D11CreateDevice for details about input parameter dependencies. To create a device without creating a swap chain, use the D3D11CreateDevice function.

If you set the pAdapter parameter to a non-NULL value, you must also set the DriverType parameter to the D3D_DRIVER_TYPE_UNKNOWN value. If you set the pAdapter parameter to a non-NULL value and the DriverType parameter to the D3D_DRIVER_TYPE_HARDWARE value, D3D11CreateDeviceAndSwapChain returns an HRESULT of E_INVALIDARG.
