## Detailed Description

AuthObserver - An object used for authenticating connections.

The AuthObserver type provides a mechanism for participating in how a Server (or a Connection) authenticates remote peers. Simply instantiate an AuthObserver and connect to the signals you are interested in. Note that new signals may be added in the future.

For example, if you only want to allow D-Bus connections from processes owned by the same uid as the server, you would use a signal handler like the following:

bool on_authorize_authenticated_peer(
const Glib::RefPtr<const Gio::IOStream>&,
const Glib::RefPtr<const Gio::Credentials>& credentials)
{
bool authorized = false;
if (credentials)
{
Glib::RefPtr<Gio::Credentials> own_credentials = Gio::Credentials::create();
try
{
if (credentials->is_same_user(own_credentials))
authorized = true;
}
catch (const Gio::Error& ex)
{
std::cerr << "Gio::Error: " << ex.what() << std::endl;
}
}
return authorized;
}

## Member Function Documentation

bool Gio::DBus::AuthObserver::allow_mechanism | ( | const std::string & | mechanism | ) |

Emits the DBusAuthObserver::signal_allow_mechanism() signal on observer.

Since glibmm 2.34:

Parameters

  mechanism | The name of the mechanism, e.g. `DBUS_COOKIE_SHA1`.

Returns
  `true` if mechanism can be used to authenticate the other peer, `false` if not.

bool Gio::DBus::AuthObserver::authorize_authenticated_peer | ( | const Glib::RefPtr< const IOStream >& | stream,
|  | const Glib::RefPtr< const Credentials >& | credentials
| ) |  |

Emits the DBusAuthObserver::signal_authorize_authenticated_peer() signal on observer.

Since glibmm 2.26:

Parameters

  stream | A IOStream for the DBusConnection.
  credentials | Credentials received from the peer or `nullptr`.

Returns
  `true` if the peer is authorized, `false` if not.

Glib::SignalProxy< bool,const std::string& > Gio::DBus::AuthObserver::signal_allow_mechanism | ( |  | ) |

Slot Prototype:
  `bool on_my_allow_mechanism(const std::string& mechanism)`

Flags: Run Last

Emitted to check if mechanism is allowed to be used.

Since glibmm 2.34:

Parameters

  mechanism | The name of the mechanism, e.g. `DBUS_COOKIE_SHA1`.

Returns
  `true` if mechanism can be used to authenticate the other peer, `false` if not.

Glib::SignalProxy< bool,const Glib::RefPtr<const IOStream>&,const Glib::RefPtr<const Credentials>& > Gio::DBus::AuthObserver::signal_authorize_authenticated_peer | ( |  | ) |

Slot Prototype:
  `bool on_my_authorize_authenticated_peer(const Glib::RefPtr<const IOStream>& stream, const Glib::RefPtr<const Credentials>& credentials)`

Flags: Run Last

Emitted to check if a peer that is successfully authenticated is authorized.

Since glibmm 2.26:

Parameters

  stream | A IOStream for the DBusConnection.
  credentials | Credentials received from the peer or `nullptr`.

Returns
  `true` if the peer is authorized, `false` if not.

## Friends And Related Function Documentation

|  | bool | take_copy = `false`
| ) |  |
| related

A Glib::wrap() method for this object.

Parameters
