Note: This API doc is automatically generated from the current development version that you can get via Subversion or as a daily snapshot from http://mpg123.org/snapshot. There may be differences (additions) compared to the latest stable release. See NEWS.libmpg123 and the overall NEWS file on libmpg123 versions and important changes between them.
Let me emphasize that the policy for libmpg123 is to always stay backwards compatible -- only additions are planned (and it's not yet planned to change the plans;-).

Detailed Description

Data structure for storing IDV3v2 tags. This structure is not a direct binary mapping with the file contents. The ID3v2 text frames are allowed to contain multiple strings. So check for null bytes until you reach the mpg123_string fill. All text is encoded in UTF-8.
