IWMPPlaylist::get_attributeCount method (wmp.h)
[The feature associated with this page, Windows Media Player SDK, is a legacy feature. It has been superseded by MediaPlayer. MediaPlayer has been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer instead of Windows Media Player SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The get_attributeCount method retrieves the number of attributes associated with the playlist.

Because playlists can come from many different sources, they can have several different sets of properties. This method retrieves the total number of properties available so that the other methods of the Playlist object can access them.
