NAME

CURLOPT_RANDOM_FILE - file to read random data from

SYNOPSIS

The application does not have to keep the string around after setting this option.

{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode res;
    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
    curl_easy_setopt(curl, CURLOPT_RANDOM_FILE, "junk.txt");
    res = curl_easy_perform(curl);
    curl_easy_cleanup(curl);
  }
}
