### Property

# Gio DBusProxy:g-interface-info

since: 2.26

#### Declaration

    property g-interface-info: Gio.DBusInterfaceInfo [ read, write ]

#### Description

Ensure that interactions with this proxy conform to the given interface. This is mainly to ensure that malformed data received from the other peer is ignored. The given `GDBusInterfaceInfo` is said to be the “expected interface”.

The checks performed are: - When completing a method call, if the type signature of the reply message isn’t what’s expected, the reply is discarded and the `GError` is set to `G_IO_ERROR_INVALID_ARGUMENT`.

- Received signals that have a type signature mismatch are dropped and a warning is logged via g_warning().

- Properties received via the initial `GetAll()` call or via the `::PropertiesChanged` signal (on the org.freedesktop.DBus.Properties interface) or set using `g_dbus_proxy_set_cached_property()` with a type signature mismatch are ignored and a warning is logged via g_warning().

Note that these checks are never done on methods, signals and properties that are not referenced in the given `GDBusInterfaceInfo`, since extending a D-Bus interface on the service-side is not considered an ABI break.
