CURLINFO_SIZE_DOWNLOAD_T3

Usage

#include <curl/curl.h>
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_SIZE_DOWNLOAD_T,
                           curl_off_t *dlp);

Overview

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

Examples

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode result;
    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
    /* Perform the request */
    result = curl_easy_perform(curl);
    if(result == CURLE_OK) {
      /* check the size */
      curl_off_t dl;
      result = curl_easy_getinfo(curl, CURLINFO_SIZE_DOWNLOAD_T, &dl);
      if(result == CURLE_OK) {
        printf("Downloaded %" CURL_FORMAT_CURL_OFF_T " bytes\n", dl);
      }
    }
  }
}

Return value

curl_easy_setopt(3) returns a CURLcode indicating success or error.

CURLE_OK (0) means everything was OK, non-zero means an error occurred, see libcurl-errors(3).
