Attribute List

The predefined attributes included with this SDK are presented alphabetically in the following table. Each attribute has a name, a global identifier, and a data type as defined by the appropriate member of the WMT_ATTR_DATATYPE enumeration. Some attributes do not use a simple data type, or are formatted according to a structure. Entries for these attributes list a structure name in the data-type column with the data type used to set the value in parentheses.

Note

See DRM Attribute List for a table of all the DRM-related attributes.

 

When you are programming with these attributes, you should use the global identifier rather than using the name as a string literal. By using the global identifier, any typographical errors will result in an error at compile time.
