Hello everyone,
I am trying to use cURL to apply request to twitter api. For example : https://api.twitter.com/1/users/lookup.json?screen_name=twitterapi,twitter

I want to save the return content (the json object) to memory, like a char* object. here's what I write:

  CURL *curl;
  CURLcode res;
  void* data;

  curl = curl_easy_init();
  if(curl) {
    curl_easy_setopt(curl, CURLOPT_URL, "https://api.twitter.com/1/users/lookup.json?screen_name=twitterapi,twitter");
        curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, &write_data);
        //curl_easy_setopt(curl, CURLINFO_PRIVATE, data);
        printf("before perform.\n");
    res = curl_easy_perform(curl);

        char *ct;
        curl_easy_getinfo(curl, CURLINFO_CONTENT_TYPE, &ct);
        printf("ct is : %s\n", ct);
        printf("data is : %s\n", (char*)data);
    /* always cleanup */
    curl_easy_cleanup(curl);
  }
  return 0;

However every time the JSON object is printed in stdout and I can't get it in memory.
Is there some method to solve this ?

Thanks.

LIU Liang
