int main(void)

  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode res;
    /* set options */
    /* Perform the entire transfer */
    res = curl_easy_perform(curl);
    /* Check for errors */
    if(res != CURLE_OK)
      fprintf(stderr, "curl_easy_perform() failed: %s\n",
              curl_easy_strerror(res));
  }
}
~~~
