Extending c bindings for extended ID3v2 tags?

[Jann Gobble]

What is the status of adding more helper methods to get extended tags such as: 
RVAD, RVA2, TALB, TCOM, TCON, TCOP, TFLT, TIME, TDRC, etc?

I would be happy if (as a non C++ programmer) there was a method to simply provide the fileref and the text tag name and get the content back as something that can then be converted (in Objective-C) to a NSString -- say char?

I am using TagLib in Objective-C using Nick Ludlam's XCode project (at https://github.com/nickludlam/TagLib.framework ) and am trying to figure out how to get extended tags back from the library.  I don't know much C++ and therefore am having a devil of a time figuring out how this might be done.  Even simple things that have libraries (APIC) included in TagLib have no non-C++ interface that I can find.

Any help?  Can anyone point me in the right direction?

Thanks!
