Elenco degli attributi
Gli attributi predefiniti inclusi in questo SDK vengono presentati alfabeticamente nella tabella seguente. Ogni attributo ha un nome, un identificatore globale e un tipo di dati definito dal membro appropriato dell'enumerazione WMT_ATTR_DATATYPE . Alcuni attributi non usano un tipo di dati semplice o vengono formattati in base a una struttura. Le voci per questi attributi elencano un nome di struttura nella colonna tipo di dati con il tipo di dati usato per impostare il valore nelle parentesi.
Nota
Vedere Elenco attributi DRM per una tabella di tutti gli attributi correlati a DRM.
Quando si esegue la programmazione con questi attributi, è consigliabile usare l'identificatore globale anziché usare il nome come valore letterale stringa. Usando l'identificatore globale, eventuali errori tipografici generano un errore in fase di compilazione.
