NAME
       CURLINFO_CONTENT_LENGTH_DOWNLOAD - get content-length of download

SYNOPSIS
       #include <curl/curl.h>

       CURLcode  curl_easy_getinfo(CURL *handle, CURLINFO_CONTENT_LENGTH_DOWN-
       LOAD,
                                  double *content_length);

DESCRIPTION
       Pass a pointer to a double to receive the content-length of  the  down-
       load.  This  is  the  value  read from the Content-Length: field. Since
       7.19.4, this returns -1 if the size isn't known.

       CURLINFO_CONTENT_LENGTH_DOWNLOAD_T(3)  is  a  newer  replacement   that
       returns a more sensible variable type.

EXAMPLE
       CURL *curl = curl_easy_init();
       if(curl) {
         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);
           }
         }
       }
