Hi All,

Kindly find the code snippet

typedef struct pageInfo_t {
  char *data;
  int len;
} pageInfo_t;

static size_t HTTPData(void *buffer, size_t size, size_t nmemb, void
*userData)
 {
  int len = size * nmemb;
  pageInfo_t *page = (pageInfo_t *)userData;
  page->data = realloc(page->data,page->len + len +1);
//if(buffer && page->data && (page->len + len <(16 * 4096))) {
    memcpy(&page->data[page->len], buffer, len);
    page->len += len;
    page->data[page->len] = 0;
  //}
  return len;
}
 //Inteface funciton that will recieve web page fom Java
jstring Java_com_samsung_jnitest_MainActivity_JNIGetWebpage( JNIEnv*
env,jobject entryObject,jstring webpageJStr,jstring host, jint port
,jstring userid, jstring pass)
{
  pageInfo_t page;
  CURL *curl;
  CURLcode res;
  char *buffer;
int memorysize = 19189;
 page.data = (char *)malloc(16 * memorysize);
    page.len = 0;

if (page.data)
    memset(page.data, 32, 16 * memorysize);

  buffer = (char *)malloc(memorysize);

   curl = curl_easy_init();
  if(curl) {
    curl_easy_setopt(curl, CURLOPT_URL, webpage);
    gs_strLastResponse = "";
    curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, HTTPData);
    curl_easy_setopt(curl, CURLOPT_WRITEDATA, &page);
    res = curl_easy_perform(curl);

curl_easy_cleanup(curl);
    (*env)->ReleaseStringUTFChars(env, webpageJStr, webpage);
    if(res == 0) {
    if(response_code == 200) {
      if (buffer) {
       page.data[page.len] = '\0';
       //page.data[page.len < memorysize ? page.len : memorysize-1] = '\0';
      sprintf(buffer, "%ld:%s \n", response_code, page.data);
 //sprintf(buffer, "pagedata(%d): %s. done.\n", page.len, page.data);
        return (*env)->NewStringUTF(env, buffer);
      }
    }
  else {
    sprintf(buffer, "Else Result %ld", response_code);
    return (*env)->NewStringUTF(env, buffer);
     // return (*env)->NewStringUTF(env, "Unable to init cURL");
   }
}

 I have given my c code snippet in my last response , regarding the buffer
size and allocation. Kindly help to dynamically increase the buffer to
accomodate the big response data
