I believe your assumption is wrong.  CoreServices is not open source, 
and this looks like it confirms my suspicion:

(from <CoreFoundation/CFURL.h>)

#if !defined(DARWIN)

struct FSRef;

CF_EXPORT
CFURLRef CFURLCreateFromFSRef(CFAllocatorRef allocator, const struct 
FSRef *fsRef);

CF_EXPORT
Boolean CFURLGetFSRef(CFURLRef url, struct FSRef *fsRef);
#endif /* !DARWIN */
