       int main(void)
       {
         CURL *curl = curl_easy_init();
         if(curl) {
           CURLcode res;
           curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
           curl_easy_setopt(curl, CURLOPT_SSLENGINE, "dynamic");
           curl_easy_setopt(curl, CURLOPT_SSLENGINE_DEFAULT, 1L);
           res = curl_easy_perform(curl);
           curl_easy_cleanup(curl);
         }
       }
