NAME
       CURLINFO_SIZE_DOWNLOAD - get the number of downloaded bytes

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_SIZE_DOWNLOAD, double
       *dlp);

DESCRIPTION
       Pass a pointer to a double to receive the total amount of bytes that
       were downloaded.  The amount is only for the latest transfer and will
       be reset again for each new transfer. This counts actual payload data,
       what's also commonly called body. All meta and header data are excluded
       and will not be counted in this number.

       _SIZE_DOWNLOAD_T&section=3">CURLINFO_SIZE_DOWNLOAD_T(3) is a newer replacement that returns a more
       sensible variable type.

         res = curl_easy_perform(curl);

         if(!res) {
           /* check the size */
