This is an alternative to using a manual throw new Wire404Exception() and is recognized by PW as a front-end 404 where PagePathHistory (or potentially other modules) are still allowed to change the behavior of the request from a 404 to something else (like a 301 redirect).

Available since version 3.0.146.

Usage

// basic usage
wire404();

// usage with all arguments
wire404(string $message = '');
