                           long *result);

  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode result;
    long verifyresult;

    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
    curl_easy_setopt(curl, CURLOPT_PROXY, "https://proxy.example:443");

    result = curl_easy_perform(curl);
    if(result != CURLE_OK) {
      printf("error: %sn", curl_easy_strerror(result));
      curl_easy_cleanup(curl);
      return 1;
    }

    result = curl_easy_getinfo(curl, CURLINFO_PROXY_SSL_VERIFYRESULT,
                               &verifyresult);
    if(result == CURLE_OK) {
      printf("The peer verification said %sn",
             (verifyresult ? "bad" : "fine"));
    }
    curl_easy_cleanup(curl);
  }
}
