long verifyresult;
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
res = curl_easy_perform(curl);
if(res) {
printf("error: %s\n", curl_easy_strerror(res));
curl_easy_cleanup(curl);
return 1;
}
res = curl_easy_getinfo(curl, CURLINFO_SSL_VERIFYRESULT,
&verifyresult);
if(!res) {
printf("The peer verification said %s\n",
(verifyresult ? "bad" : "fine"));
