Can you make the curl command line tool to work? If so, then you know libcurl
works and downloads it fine if used correctly.

You really *SHOULD* see what return code you get from curl_easy_perform().
What if it returns an error? Then use the CURLOPT_ERRORBUFFER option to set a
error message buffer to get a descriptive message to read.

I could only see one immidiate minor problem:

This function should return 'write', the number of bytes that fwrite()
actually wrote, so that libcurl can properly bail out on write errors.
