curl_global_init(CURL_GLOBAL_ALL);
ctx = curl_easy_init();
curl_easy_setopt (ctx, CURLOPT_WRITEFUNCTION, write_callback);
curl_easy_setopt (ctx, CURLOPT_URL, "http://172.30.2.164/xxx/yyy/");
curl_easy_perform (ctx);

curl_easy_setopt (ctx, CURLOPT_READFUNCTION, read_callback);
curl_easy_perform (ctx);

Nothing happened.
