os.notify #

fn new() !FdNotifier

new creates a new EpollNotifier The FdNotifier interface is returned to allow OS specific implementations without exposing the concrete type

interface FdEvent {
	fd   int
	kind FdEventType
}

interface FdNotifier {
mut:
	add(fd int, events FdEventType, conf ...FdConfigFlags) !
	modify(fd int, events FdEventType, conf ...FdConfigFlags) !
	remove(fd int) !
	wait(timeout time.Duration) []FdEvent
	close() !
}

Backends should provide a new()?FdNotifier function

enum FdConfigFlags {
	edge_trigger
	one_shot
	wake_up
	exclusive
}

enum FdEventType {
	read
	write
	peer_hangup
	exception
	error
	hangup
}

struct C.epoll_event {
	events u32
	data   C.epoll_data_t
}
