Creates a DXGI 1.0 factory that you can use to generate other DXGI objects.
- riid [in]
The globally unique identifier (GUID) of the IDXGIFactory object referenced by the ppFactory parameter.
- ppFactory [out]
Address of a pointer to an IDXGIFactory object.
Returns S_OK if successful; otherwise, returns one of the following DXGI_ERROR.
If the CreateDXGIFactory function succeeds, the reference count on the IDXGIFactory interface is incremented. To avoid a memory leak, when you finish using the interface, call the IDXGIFactory::Release method to release the interface.
Note Starting with Windows 8, all DXGI factories (regardless if they were created with CreateDXGIFactory or CreateDXGIFactory1) enumerate adapters identically. The enumeration order of adapters, which you retrieve with IDXGIFactory::EnumAdapters or IDXGIFactory1::EnumAdapters1, is as follows:
- Adapter with the output on which the desktop primary is displayed. This adapter corresponds with an index of zero.
- Adapters with outputs.
- Adapters without outputs.
The CreateDXGIFactory function does not exist for Windows Store apps. Instead, Windows Store apps use the CreateDXGIFactory1 function.
Creating a DXGI 1.0 Factory
The following code example demonstrates how to create a DXGI 1.0 factory. This example uses the __uuidof() intrinsic to obtain the REFIID, or GUID, of the IDXGIFactory interface.
IDXGIFactory * pFactory; HRESULT hr = CreateDXGIFactory(__uuidof(IDXGIFactory), (void**)(&pFactory) );
