GioDBusMethodInvocationreturn_error

since: 2.26

Declaration [src]

void
g_dbus_method_invocation_return_error (
  GDBusMethodInvocation* invocation,
  GQuark domain,
  gint code,
  const gchar* format,
  ...
)

Description [src]

Finishes handling a D-Bus method call by returning an error.

See g_dbus_error_encode_gerror() for details about what error name will be returned on the wire. In a nutshell, if the given error is registered using g_dbus_error_register_error() the name given during registration is used. Otherwise, a name of the form org.gtk.GDBus.UnmappedGError.Quark... is used. This provides transparent mapping of GError between applications using GDBus.

If you are writing an application intended to be portable, always register errors with g_dbus_error_register_error() or use g_dbus_method_invocation_return_dbus_error().

This method will take ownership of invocation. See GDBusInterfaceVTable for more information about the ownership of invocation.

Since 2.48, if the method call requested for a reply not to be sent then this call will free invocation but otherwise do nothing (as per the recommendations of the D-Bus specification).

Available since: 2.26

This method is not directly available to language bindings.
