Gio.DBusConnection.prototype.call_sync

function call_sync(bus_name: String, object_path: String, interface_name: String, method_name: String, parameters: GLib.Variant, reply_type: GLib.VariantType, flags: Gio.DBusCallFlags, timeout_msec: Number(gint), cancellable: Gio.Cancellable): GLib.Variant {
    // Gjs wrapper for g_dbus_connection_call_sync()
}
  

Synchronously invokes the method_name method on the interface_name D-Bus interface on the remote object at object_path owned by bus_name.

If connection is closed then the operation will fail with Gio.IOErrorEnum.closed. If cancellable is canceled, the operation will fail with Gio.IOErrorEnum.cancelled. If parameters contains a value not compatible with the D-Bus protocol, the operation fails with Gio.IOErrorEnum.invalid_argument.

If reply_type is non-null then the reply will be checked for having this type and an error will be raised if it does not match. Said another way, if you give a reply_type then any non-null return value will be of this type.

If the parameters GLib.Variant is floating, it is consumed. This allows convenient 'inline' use of GLib.Variant.new, e.g.: |[<!-- language="C" --> g_dbus_connection_call_sync (connection, "org.freedesktop.StringThings", "/org/freedesktop/StringThings", "org.freedesktop.StringThings", "TwoStrings", g_variant_new ("(ss)", "Thing One", "Thing Two"), NULL, G_DBUS_CALL_FLAGS_NONE, -1, NULL, &error); ]|

The calling thread is blocked until a reply is received. See Gio.DBusConnection.prototype.call for the asynchronous version of this method.
