Exclusion des fonctions DDI pour les contextes différés

Cette section s’applique uniquement à Windows 7 et versions ultérieures et Windows Server 2008 R2 et versions ultérieures du système d’exploitation Windows.

Lorsque le runtime Microsoft Direct3D appelle la fonction CreateDeferredContext du pilote d’affichage en mode utilisateur pour créer un contexte différé, le pilote fournit les fonctions que le runtime peut appeler pour ce contexte différé. Le pilote remplit les membres de la structure D3D11DDI_DEVICEFUNCS vers laquelle pointe le membre p11ContextFuncs de la structure D3D11DDIARG_CREATEDEFERREDCONTEXT . Le pilote fournit uniquement un sous-ensemble de fonctions pour un contexte différé, comme le pilote le fait pour un contexte immédiat.

Le pilote exclut de nombreuses fonctions pour les contextes différés en définissant les membres de D3D11DDI_DEVICEFUNCS ou D3D11_1DDI_DEVICEFUNCS suivants sur NULL :
