I don't know of any official specifications of it, but it's common to
a cue called "Loop start", and a cue called "Loop End".
Well, I didn't find any way to use libsndfile to get the cue points.
They are displayed using sndfile-info, but I don't think you can get
via the libsndfile api without parsing the text output of the functions
It's simple to implement without libsndfile though. Just steal the code
from radium. :-)
