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.

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

PROTOCOLS

       All

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 dl;
           res = curl_easy_getinfo(curl, CURLINFO_SIZE_DOWNLOAD, &dl);
           if(!res) {
             printf("Downloaded %.0f bytes\n", cl);
           }
         }
       }
