Here's a C++ flavor of the accepted answer from alex-jasmin

#include 
#include 
#include 

size_t writefunc(void *ptr, size_t size, size_t nmemb, std::string *s) 
{
  s->append(static_cast(ptr), size*nmemb);
  return size*nmemb;
}

int main(void)
{
  CURL *curl = curl_easy_init();
  if (curl)
  {
    std::string s;

    curl_easy_setopt(curl, CURLOPT_URL, "curl.haxx.se");
    curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, writefunc);
    curl_easy_setopt(curl, CURLOPT_WRITEDATA, &s);

    CURLcode res = curl_easy_perform(curl);

    std::cout << s << std::endl;

    /* always cleanup */
    curl_easy_cleanup(curl);
  }
  return 0;
}
