Try:

qdbc -dmme "select * from trksessionview"

Is there a list of fids output? If so, then assuming your tracksessionid is 3, you could do the following to get a list 
of fid,titles:

qdbc -dmme "select fid, title from library where fid IN (select fid from trksessionview where trksessionid=3"

You can so the same qdbc does in your C code.

You can extend the state to join with library_artists for example and also retrieve the artist name.

You will want to get an official release of the product.  If not sure how to do that then it's best to talk to your QNX 
sales rep.

This MME version above is experimental, where did you get this?

This is also experimental, it probably has a header file mismatch with the mme-generic, such that both are having 
communication problems.


Also, all of these are dated 2008, I wonder where they came from? Without knowing exactly where you got these from, all 
I can say is that you probably need to try to find a specific release (like Aviage 1.2) and take all of the binaries 
from there.
