CURLINFO_SIZE_DOWNLOAD_T(3)                           Library Functions Manual

NAME
       CURLINFO_SIZE_DOWNLOAD_T - get the number of downloaded bytes

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_SIZE_DOWNLOAD_T,
                                  curl_off_t *dlp);

DESCRIPTION
       Pass a pointer to a curl_off_t to receive the total amount of bytes
       that were downloaded. The amount is only for the latest transfer and
       gets reset again for each new transfer. This counts actual payload
       data, what's also commonly called body. All meta and header data is
       excluded from this amount.

PROTOCOLS
       This functionality affects all supported protocols

EXAMPLE
       int main(void)
       {
         CURL *curl = curl_easy_init();
         if(curl) {
           CURLcode res;
           curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");

           /* Perform the request */
           res = curl_easy_perform(curl);

           if(!res) {
             /* check the size */
             curl_off_t dl;
             res = curl_easy_getinfo(curl, CURLINFO_SIZE_DOWNLOAD_T, &dl);
             if(!res) {
               printf("Downloaded %" CURL_FORMAT_CURL_OFF_T " bytes\n", dl);
             }
           }
         }
       }
