CURLINFO_SIZE_DOWNLOAD_T - get the number of downloaded bytes
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_SIZE_DOWNLOAD_T,
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.
CURL *curl = curl_easy_init();
curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");
/* Perform the request */
res = curl_easy_perform(curl);
/* check the size */
res = curl_easy_getinfo(curl, CURLINFO_SIZE_DOWNLOAD_T, &dl);
printf("Downloaded %" CURL_FORMAT_CURL_OFF_T " bytes\n", dl);
