    //  The following comments apply to SharePoint Windows classic authentication.
    //  -------------------------------------------------------------------------
    //  For example, imagine our SharePoint endpoint is https://xyzoffice.mycompany.com/
    //  The SHAREPOINT_NTLM_DOMAIN would be "mycompany.com"
    //  The SHAREPOINT_HTTPS_DOMAIN would be "xyzoffice.mycompany.com"
    //  Also, the SHAREPOINT_USERNAME would be just the name, not a full email address.
    //  for example, "chilkat" instead of "chilkat@mycompany.com"

    CkHttpW http;

    //  If SharePoint Windows classic authentication is used, then set the
    //  Login, Password, LoginDomain, and NtlmAuth properties.
    http.put_Login(L"SHAREPOINT_USERNAME");
    http.put_Password(L"SHAREPOINT_PASSWORD");
    http.put_LoginDomain(L"SHAREPOINT_NTLM_DOMAIN");
    http.put_NtlmAuth(true);

    //  -------------------------------------------------------------------------
    //  The more common case is to use SharePoint Online authentication (via the SPOIDCRL cookie).
    //  If so, do not set Login, Password, LoginDomain, and NtlmAuth, and instead
    //  establish the cookie as shown at SharePoint Online Authentication

    //  This example downloads the file named "Domain Name created for Exchange.docx"

    //  Note: I was initially confused by the "$value" part of the URL.
    //  When I see something like $value, I immediately think that it's some sort of
    //  variable or placeholder to be replaced with an actual value.  In this case,
    //  the "$value" is literally part of the URL.  It's not replace with anything.

    const wchar_t *url = L"https://SHAREPOINT_HTTPS_DOMAIN/_api/web/GetFolderByServerRelativeUrl('/Documents')/Files('Domain Name created for Exchange.docx')/$value";
    const wchar_t *localFilePath = L"qa_output/x.docx";

    bool success = http.Download(url,localFilePath);
    if (success != true) {
        wprintf(L"%s\n",http.lastErrorText());
        return;
    }

    wprintf(L"File successfully downloaded from SharePoint.\n");
