CURLINFO_SIZE_DOWNLOAD_T - get the number of downloaded bytes

#include <curl/curl.h>

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

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 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.

All

  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 */
      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);
      }
    }
  }
