/**
 * udisks_daemon_util_check_authorization_sync:
 * @daemon: A #UDisksDaemon.
 * @object: (allow-none): The #GDBusObject that the call is on or %NULL.
 * @action_id: The action id to check for.
 * @options: (allow-none): A #GVariant to check for the <quote>auth.no_user_interaction</quote> option or %NULL.
 * @message: The message to convey (use N_).
 * @invocation: The invocation to check for.
 *
 * Checks if the caller represented by @invocation is authorized for
 * the action identified by @action_id, optionally displaying @message
 * if authentication is needed. Additionally, if the caller is not
 * authorized, the appropriate error is already returned to the caller
 * via @invocation.
 *
 * The calling thread is blocked for the duration of the authorization
 * check which could be a very long time since it may involve
 * presenting an authentication dialog and having a human user use
 * it. If <quote>auth.no_user_interaction</quote> in @options is %TRUE
 * no authentication dialog will be presented and the check is not
 * expected to take a long time.
 *
 * See <xref linkend="udisks-polkit-details"/> for the variables that
 * can be used in @message but note that not all variables can be used
 * in all checks. For example, any check involving a #UDisksDrive or a
 * #UDisksBlock object can safely include the fragment
 * <quote>$(drive)</quote> since it will always expand to the name of
 * the drive, e.g. <quote>INTEL SSDSA2MH080G1GC (/dev/sda1)</quote> or
 * the block device file e.g. <quote>/dev/vg_lucifer/lv_root</quote>
 * or <quote>/dev/sda1</quote>. However this won't work for operations
 * that isn't on a drive or block device, for example calls on the
 * <link linkend="gdbus-interface-org-freedesktop-UDisks2-Manager.top_of_page">Manager</link>
 * object.
 *
 * Returns: %TRUE if caller is authorized, %FALSE if not.
