This is what I'm doing but the parameter never makes it to the header
callback, it's null in the callback:

  config->curl = curl_easy_init();

  retcode = curl_easy_setopt(config->curl, CURLOPT_WRITEFUNCTION,
write_function);
  retcode = curl_easy_setopt(config->curl, CURLOPT_HEADERFUNCTION,
header_function);
  retcode = curl_easy_setopt(config->curl, CURLOPT_WRITEDATA, config);

  sprintf(url, "%s%s%s?feed=%s", FEED_SERVER, FEED_PREFIX,
FEED_REQUEST_POSITION, TEST_FEED_NAME);

  retcode = curl_easy_setopt(config->curl, CURLOPT_URL, strdup(url));

  retcode = curl_easy_perform(config->curl);

I'll probably do that if I can't get this working.

Thanks for the help!
