    // The start line of an HTTP response, called the status line, contains the following information:
    // 
    //     The protocol version, usually HTTP/1.1.
    //     A status code, indicating success or failure of the request. Common status codes are 200, 404, or 302
    //     A status text. A brief, purely informational, textual description of the status code to help a human understand the HTTP message.
    // 
    // A typical status line looks like: HTTP/1.1 404 Not Found.

    // The ResponseStatusCode property contains the integer response code:
    wprintf(L"Response status code = %d\n",CkRestW_getResponseStatusCode(rest));

    // The ResponseStatusText property contains the text (if any) that follows the status code on the status line.
    wprintf(L"Response status text = %s\n",CkRestW_responseStatusText(rest));

    // In this case, the sample output is:
    // 
    // Response status code = 401
    // Response status text = Unauthorized
