       #include	<curl/curl.h>

       CURLcode	 curl_easy_getinfo(CURL	*handle, CURLINFO_CONTENT_LENGTH_DOWN-

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

	 /* Perform the	request	*/
	 res = curl_easy_perform(curl);

	 if(!res) {
	   /* check the	size */
	   double cl;
	   res = curl_easy_getinfo(curl, CURLINFO_CONTENT_LENGTH_DOWNLOAD, &cl);
	   if(!res) {
	     printf("Size: %.0f\n", cl);
	   }
	 }
       }
