Excluindo funções DDI para contextos adiados
Esta seção se aplica somente ao Windows 7 e posterior e ao Windows Server 2008 R2 e versões posteriores do sistema operacional Windows.
Quando o runtime do Microsoft Direct3D chama a função CreateDeferredContext do driver de exibição no modo de usuário para criar um contexto adiado, o driver fornece as funções que o runtime pode chamar para esse contexto adiado. O driver preenche membros da estrutura D3D11DDI_DEVICEFUNCS para a qual o membro p11ContextFuncs da estrutura D3D11DDIARG_CREATEDEFERREDCONTEXT aponta. O driver fornece apenas um subconjunto de funções para um contexto adiado, como o driver faz para um contexto imediato.
O driver exclui muitas funções para contextos adiados definindo os seguintes membros de D3D11DDI_DEVICEFUNCS ou D3D11_1DDI_DEVICEFUNCS como NULL:
