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, "https://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);
           }
         }
       }
