Gio.DBusProxy.prototype.call_with_unix_fd_list_sync

function call_with_unix_fd_list_sync(method_name: String, parameters: GLib.Variant, flags: Gio.DBusCallFlags, timeout_msec: Number(gint), fd_list: Gio.UnixFDList, cancellable: Gio.Cancellable): [return_value: GLib.Variant, out_fd_list: Gio.UnixFDList] {
    // Gjs wrapper for g_dbus_proxy_call_with_unix_fd_list_sync()
}

Like Gio.DBusProxy.prototype.call_sync but also takes and returns Gio.UnixFDList objects.

This method is only available on UNIX.

Since 2.30

method_name: Name of method to invoke.
parameters: A GLib.Variant tuple with parameters for the signal or null if not passing parameters.
flags: Flags from the Gio.DBusCallFlags enumeration.
timeout_msec: The timeout in milliseconds (with %G_MAXINT meaning "infinite") or -1 to use the proxy default timeout.
fd_list: A Gio.UnixFDList or null.
cancellable: A Gio.Cancellable or null.
return_value: null if @error is set. Otherwise a GLib.Variant tuple with return values. Free with GLib.Variant.prototype.unref.
out_fd_list: Return location for a Gio.UnixFDList or null.
