iv_examples – ivykis examples Exampleivykis is initialised by calling iv_init(3). This function is the first function to call when dealing with ivykis — it has to be called before registering file descriptors or timers. The ivykis main event loop is started by calling iv_main(3). This function generally does not return, except when iv_quit(3) is called…
