Yes. The documentation says:
"Boolean CFURLGetFileSystemRepresentation (
    CFURLRef url,
    Boolean resolveAgainstBase,
    UInt8 *buffer,
    CFIndex maxBufLen
);

No more than maxBufLen bytes are written to buffer. If url requires 
more than maxBufLen bytes to represent itself, including the 
terminating null byte, this function returns false. To avoid this 
possible failure, you should pass a buffer with size of at least the 
maximum path length for the file system in question."

So the loop will only exit when the full path (including the null byte) 
will fit.
