SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_SPEED_DOWNLOAD,
                           double *speed);

    /* Perform the request */
    result = curl_easy_perform(curl);

    if(result == CURLE_OK) {
      double speed;
      result = curl_easy_getinfo(curl, CURLINFO_SPEED_DOWNLOAD, &speed);
      if(result == CURLE_OK) {
        printf("Download speed %.0f bytes/secn", speed);
      }
