CURLINFO_SPEED_DOWNLOAD_T - Man Page

#include <curl/curl.h>

CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_SPEED_DOWNLOAD_T,
                           curl_off_t *speed);

Pass a pointer to a curl_off_t to receive the average download speed that curl measured for the complete download. Measured in bytes/second.

This functionality affects all supported protocols

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) {
      curl_off_t speed;
      res = curl_easy_getinfo(curl, CURLINFO_SPEED_DOWNLOAD_T, &speed);
      if(!res) {
        printf("Download speed %" CURL_FORMAT_CURL_OFF_T " bytes/sec\n",
               speed);
      }
    }
  }
}
