int main(void)
{


  CURL *curl = curl_easy_init();


  if(curl) {


    CURLcode result;


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


    result = curl_easy_perform(curl);


    if(result == CURLE_OK) {


      long cseq;


      curl_easy_getinfo(curl, CURLINFO_RTSP_SERVER_CSEQ, &cseq);


    }


    curl_easy_cleanup(curl);


  }
