The ev-io unblocked feature ensures efficient and non-blocking I/O handling within the context of event-driven programming with libraries like libev . void io_cb(EV_P_ struct ev_io *w, int revents) //

This example sets up an ev_io watcher for reading and writing on STDIN_FILENO . When the file descriptor becomes ready for reading or writing, io_cb is invoked. void io_cb(EV_P_ struct ev_io *w
