That's the right approach. Presumably, you want to do something with those
first 100 bytes, and that's the function to do it in. Once you've received
all you want, just return 0 from that function and the transfer will
stop. You can also set a CURLOPT_RANGE that will work on certain protocols
with certain servers with certain URLs, but since there's no guarantee it
will work, you'll still need to count bytes in the writefunction.
