namespace remoting {
// An interface for enabling or disabling "curtain mode" on a Chromoting host.
// Curtain mode is designed to ensure privacy for remote users. It guarantees
// the following:
// 1. The local display of the host does not display the remote user's
// actions during the connection.
// 2. The local keyboard and mouse (and other input devices) do not interfere
// with the remote user's session.
// 3. When the remote session terminates, the host computer is left in a
// secure state (for example, locked).
class Curtain {
public:
virtual ~Curtain() { }
// Enable or disable curtain mode. This method is called with |enable| = true
// when a connection authenticates and with |enable| = false when a connection
// terminates (even if due to abnormal termination of the host process).
virtual void EnableCurtainMode(bool enable) = 0;
// Create the platform-specific curtain mode implementation.
// TODO(jamiewalch): Until the daemon architecture is implemented, curtain
// mode implementations that cannot easily be reset by the user should check
// to see if curtain mode is already enabled here and disable it if so. This
// is to provide an easy way of recovering if the host process crashes while
// a connection is active. Once the daemon architecture is in place, it will
// be responsible for calling EnableCurtainMode(false) as part of its crash
// recovery logic.
