This method is only available on UNIX.

When designing D-Bus APIs that are intended to be interoperable, please note that non-GDBus implementations of D-Bus can usually only access file descriptors if they are referenced by a value of type G_VARIANT_TYPE_HANDLE in the body of the message.

Otherwise this method encodes the error in @self as a #GError using g_dbus_error_set_dbus_error() using the information in the DBusMessageHeaderField::ErrorName header field of @self as well as the first string item in @self’s body.

§Returns

true if @error was set, false otherwise.

source
