TagsReader.ID3V2_UniqueFramesCountGet method

Previous pageReturn to chapter overviewNext page



Obtains the number of unique frames found inside the ID3V2 tag. The identifier of each unique frame can be obtained through the TagsReader.ID3V2_UniqueFramesIdGet method.


Certain ID3V2 frames, for example APIC or COMM, can be available in multiple instances inside the same ID3V2 tag: when this method is called, the enumeration will not keep count of multiple instances of a specific frame but will only report the availability of the frame itself; once the availability of a specific frame is known, single specific frames can be enumerated using the TagsReader.ID3V2_FrameCountGet method.


For further details about methods related to tags reading refer to the TagsReader object.

For details about the reading of tags see the How to read TAG information in sound files tutorial.
