system_collapse(3) Arcan Lua API system_collapse(3) NAME system_collapse - Collapse important subsystems, leaving only frameservers alive. SYNOPSIS nil system_collapse( applname, noadopt ) DESCRIPTION This function purges audio/video/events from everything not strictly re- lated to frameservers. Then, if applname was specified, it loads and runs applname and invokes an applname_adopt function for each frameserver re- lated VID , unless noadopt has been set to true. This enables recovery from bad system states switching to an app that can permit the user to clean-up and save important information that would otherwise be lost or simply to switch active scripts while keeping core services intact. If ap- plname is left undefined, the current namespaces and active scripts will be re-used but the scripting context will be reset. NOTES 1 frameservers existing in multiple context stack levels are collated down to a flat, new context. 2 if the number of running frameservers is higher than the current new context vobj limit, the vobj limit will be raised. 3 if there are more running frameservers in all contexts combined than what is permitted (compile-time) some frameservers will be truncated and deleted. (likely to hit system process and descriptor limits before that happens). 4 frameservers will have their order value set depending on the con- text they were previously allocated in. 5 the search space for applname is constrained to namespace defined by the APPLBASE namespace.
