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


DESCRIPTION

       Pass a pointer to a null-terminated string as parameter. It will be
       used as the identifier for the crypto engine you want to use for your
       private key.

       this option.

       if(curl) {
         curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
         curl_easy_setopt(curl, CURLOPT_SSLENGINE, "dynamic");
         ret = curl_easy_perform(curl);
         curl_easy_cleanup(curl);
       }

       Only if the SSL backend is OpenSSL built with engine support.


RETURN VALUE

       CURLE_OK - Engine found.

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

       CURLE_SSL_ENGINE_INITFAILED - Engine found but initialization failed.
