Lista de Atributos
Os atributos predefinidos incluídos com esse SDK são apresentados em ordem alfabética na tabela a seguir. Cada atributo tem um nome, um identificador global e um tipo de dados, conforme definido pelo membro apropriado da enumeração WMT_ATTR_DATATYPE . Alguns atributos não usam um tipo de dados simples ou são formatados de acordo com uma estrutura. As entradas para esses atributos listam um nome de estrutura na coluna de tipo de dados com o tipo de dados usado para definir o valor entre parênteses.
Observação
Consulte Lista de Atributos DRM para obter uma tabela de todos os atributos relacionados ao DRM.
Ao programar com esses atributos, você deve usar o identificador global em vez de usar o nome como um literal de cadeia de caracteres. Usando o identificador global, quaisquer erros tipográficos resultarão em um erro em tempo de compilação.
