Description
int id3_get_version (string filename)id3_get_version() retrieves the version(s) of the ID3 tag(s) in the MP3 file. As a tag can contain ID3 v1.x and v2.x tags, the return value of this function should be bitwise compared with the predefined constants ID3_V1_0, ID3_V1_1 and ID3_V2.
Замечание: Instead of a filename you may also pass a valid stream resource.
