was available.

if(curl) {
  CURLcode res;

  curl_easy_setopt(curl, CURLOPT_PROXY, "socks5://127.0.0.1");
  res = curl_easy_perform(curl);
  if(res == CURLE_PROXY) {
    long proxycode;
    res = curl_easy_getinfo(curl, CURLINFO_PROXY_ERROR, &proxycode);
    if(!res && proxycode)
      printf("The detailed proxy error: %ld\\n", proxycode);
  }
