# API documentation for libmpg123, libout123, and libsyn123

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, NEWS.libout123, NEWS.libsyn123, and the overall NEWS file on libmpg123 versions and important changes between them.
Let me emphasize that the policy for the lib*123 family is to always stay backwards compatible -- only additions are planned (and it's not yet planned to change the plans;-).

## Detailed Description

Sub data structure for ID3v2, for storing picture data including comment. This is for the ID3v2 APIC field. You should consult the ID3v2 specification for the use of the APIC field ("frames" in ID3v2 documentation, I use "fields" here to separate from MPEG frames).
