No, you need to look at the application-level return code as well. You also
need to look at the returned headers, because some servers won't support
ranges and won't return an error code.

You're right, the documentation isn't very clear on this point. IIUC,
CURLOPT_RESUME_FROM affects both ends of the transfer, while
CURLOPT_RANGE only specifies a range to the server.
