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.

    /* 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);
