What happened to CINs? And how else can another language work with LabVIEW?

The vast majority of software developers are not graphical programmers.  I have been using LabVIEW for a long time, and am looking for better ways to integrate LabVIEW with software developed in other languages; and across operating systems.  For now, let's just talk C.

I'm well aware of LabVIEW's ability to integrate shared libraries:

But I wonder what happened to CINs?

Did they get dropped from support with LabVIEW 2009?  Or are they still kicking around somewhere?
