int main(void)
{


  CURL *curl = curl_easy_init();


  if(curl) {


    CURLcode result;


    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");


    /* delegate if okayed by policy */


    curl_easy_setopt(curl, CURLOPT_GSSAPI_DELEGATION,


                     CURLGSSAPI_DELEGATION_POLICY_FLAG);


    result = curl_easy_perform(curl);
