Interfacing C library

Hello,

I am creating an ID3 tag editor in squeak smalltalk. There is a C library called id3lib that is capable of parsing and modifying id3tags.
I have been searching the squeak wiki but I do not understand how to interface smalltalk code with this library(looked at FFI,Named Primitives). Any help would be greatly appreciated.

Thanking you,
Karthic Kumaran

FFI is the way to go. For instructions on using it:
http://wiki.squeak.org/squeak/1414

Basically, you create a method that contains just a pragma
detailing the calling convention of your target C method

To get it, point Monticello at http://source.squeak.org/FFI, and
load
FFI-Pools
FFI-Kernel
FFI-Tests
FFI-Win32
FFI-Unix
FFI-MacOS

The tests and platform-specific bits have some good examples on
using it too
