    curl_easy_setopt(curl, CURLOPT_URL, \"http://www.google.com\");

Answer 1

I use Joachim Isaksson's answer with a modern C++ adaptation of CURLOPT_WRITEFUNCTION.

No nagging by the compiler for C-style casts.

static auto WriteCallback(char* ptr, size_t size, size_t nmemb, void* userdata) -> size_t {
  static_cast(userdata)->append(ptr, size * nmemb);
  return size * nmemb;
}
