shutdown(3) Arcan Lua API shutdown(3) NAME shutdown - Queue a shutdown event. SYNOPSIS nil shutdown( optmsg, optcode ) DESCRIPTION This function will shutdown the engine and terminate the process when deemed safe. This means that it will not happened immediately, but rather that an event will be queued internally in order to give frameservers and other pending-data related tasks time to clean-up. The system interpreta- tion of optcode varies with the underlying environment, though the EXIT_SUCCESS and EXIT_FAILURE constants are propagated and useful here. There is also a special constant, EXIT_SILENT that will return an EXIT_SUCCESS to the outer system, but only signal a 'display server lost' action to external clients, rather than asking them to shut down. NOTES 1 by default, the exit code corresponds to system EXIT_SUCCESS , but can be set to a custom value through optcode . 2 optmsg is filtered to only accept [a-Z,.0-9] and whitespace. EXAMPLE function shutdown0() return shutdown(); end EXAMPLE function shutdown1() return shutdown("giving up", -1); end system August 2026 shutdown(3)
