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 com-
     monly called body. All meta and header data are excluded and
     will not be counted in this number.

     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 */
         double dl;
         res = curl_easy_getinfo(curl, CURLINFO_SIZE_DOWNLOAD, &dl);
         if(!res) {
