tiny.mprompt.init

1/// Initializes the runtime from `cfg`, or from the defaults when `cfg` is null, so a program calls2/// it once before creating any prompt to replace the default configuration. Only the first3/// initialization in a process takes effect: later calls return at once, and the first4/// `promptCreate` initializes with the defaults when `init` has not run. Initialization draws the5/// guard cookie from the clock and an address. Unless overcommit mode is on, initialization6/// installs a fault handler for stack growth and an alternate signal stack of 64 KiB for the7/// calling thread. The fault handler takes segmentation faults, and bus faults as well on platforms8/// other than Linux. The runtime keeps the fault handler that was installed before, passes it every9/// fault it cannot use for stack growth, and aborts the process when there was none. Initialization10/// uses plain process globals and no lock, so two threads that initialize at the same time race.11/// The program stops with a panic when the configuration leaves no usable stack or when a handler12/// or signal stack cannot be installed.13pub fn init(cfg: ?*const Config) void {14    ensureInitialized(cfg);15}
