CFStringRef and NSString are tool-free bridged

you can do this:

CFURLRef url = CFCreateURLWithString(kCFAllocatorDefault, 
(CFStringRef)filePath, NULL);
And you must release it when done (even with GC)
CFRelease(url);

and NSURL and CFURL are tool free bridged, so can do this:

CFURLGetFSRef((CFURLRef)[NSURL URLWithString:filePath], &output);
