       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSLENGINE, char *id);

DESCRIPTION
       Pass a pointer to a null-terminated string as parameter. It will be

       private key.

         curl_easy_setopt(curl, CURLOPT_SSLENGINE, "dynamic");
         ret = curl_easy_perform(curl);
         curl_easy_cleanup(curl);
       }

       CURLE_SSL_ENGINE_NOTFOUND - Engine not found, or OpenSSL was not built
       with engine support.
