Parámetros
[in] pDevice
Tipo: IUnknown*
Especifica un dispositivo Direct3D 12 existente que se usará para la interoperabilidad de Direct3D 11. Puede que no sea NULL.
Flags
Tipo: UINT
Una o varias marcas OR bit a bit de D3D11_CREATE_DEVICE_FLAG. Estas son las mismas marcas que las usadas por D3D11CreateDeviceAndSwapChain. Especifica qué capas de tiempo de ejecución se van a habilitar. Las marcas deben ser compatibles con las marcas de dispositivo y nodeMask debe ser un subconjunto de NodeMask proporcionado a la API actual.
[in, optional] pFeatureLevels
Tipo: const D3D_FEATURE_LEVEL*
Matriz de cualquiera de las siguientes opciones:
- D3D_FEATURE_LEVEL_12_1
- D3D_FEATURE_LEVEL_12_0
- D3D_FEATURE_LEVEL_11_1
- 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
El primer nivel de característica menor o igual que el nivel de características del dispositivo Direct3D 12 se usará para realizar la validación de Direct3D 11. Se producirá un error en la creación si no se proporcionan niveles de características aceptables. Proporcionar NULL tendrá como valor predeterminado el nivel de características del dispositivo Direct3D 12.
FeatureLevels
Tipo: UINT
Tamaño de (es decir, el número de elementos de) la matriz pFeatureLevels .
[in, optional] ppCommandQueues
Tipo: IUnknown* const *
Matriz de colas únicas para que use D3D11On12. Las colas deben ser del tipo de cola de comandos 3D.
NumQueues
Tipo: UINT
Tamaño de (es decir, el número de elementos de) la matriz ppCommandQueues .
NodeMask
Tipo: UINT
Nodo del dispositivo Direct3D 12 que se va a usar. Solo se pueden establecer 1 bit.
[out, optional] ppDevice
Tipo: ID3D11Device**
Puntero al id3D11Device devuelto. Puede ser NULL.
[out, optional] ppImmediateContext
Tipo: ID3D11DeviceContext**
Puntero al id3D11DeviceContext devuelto. Puede ser NULL.
[out, optional] pChosenFeatureLevel
Tipo: D3D_FEATURE_LEVEL*
Puntero al nivel de característica devuelto. Puede ser NULL.
Valor devuelto
Tipo: HRESULT
Este método devuelve uno de los códigos de retorno de Direct3D 12 que se documentan para D3D11CreateDevice.
Este método devuelve DXGI_ERROR_SDK_COMPONENT_MISSING si especifica D3D11_CREATE_DEVICE_DEBUG en Marcas y la versión incorrecta de la capa de depuración está instalada en el equipo. Instale la versión más reciente de Windows SDK para obtener la versión correcta.
Comentarios
La firma de función PFN_D3D11ON12_CREATE_DEVICE se proporciona como definición de tipo, para que pueda usar técnicas de vinculación dinámica (GetProcAddress) en lugar de vincular estáticamente.
