+/**
+ * Sets a flag indicating that the caller of the method is prepared
+ * to wait for interactive authorization to take place (for instance
+ * via Polkit) before the actual method is processed.
+ *
+ * The flag is #FALSE by default; that is, by default the other end is
+ * expected to make any authorization decisions non-interactively
+ * and promptly. It may use the error
+ * #DBUS_ERROR_INTERACTIVE_AUTHORIZATION_REQUIRED to signal that
+ * authorization failed, but could have succeeded if this flag had
+ * been used.
+ *
+ * For messages whose type is not #DBUS_MESSAGE_TYPE_METHOD_CALL,
+ * this flag is meaningless and should not be set.
+ *
+ * On the protocol level this toggles
+ * #DBUS_HEADER_FLAG_ALLOW_INTERACTIVE_AUTHORIZATION.
+ *
+ * @param message the message
+ * @param allow #TRUE if interactive authorization is acceptable
