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