Why would you want to do this? It's easy enough to do with Carbon, or 
with a quick Cocoa wrapper around the relevant methods, or with 
CFURLCopyFSRef.

If you want to use FSRefs with straight Darwin, I'd recommend against 
it - FSRefs are designed for Mac GUI apps, and with plain old Darwin at 
the command line, files are probably much less likely to move around 
anyway, so you don't really need them.

At any rate, the only way you'll make an FSRef without Carbon is if you 
manage to crack the format, which is probably more trouble than it's 
worth.
