Determines whether the caller has the specified privileges
    or identifier. In addition to checking for a privilege or an
    identifier, the Check Privilege and Wait service determines if
    the caller's use of privilege needs to be audited.

    $CHECK_PRIVILEGEW completes synchronously; that is, it returns
    the final status to the caller only after receiving an explicit
    confirmation from the audit server that the associated audit, if
    enabled, has been performed.
