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

fn FdConfigFlags.from() FdConfigFlags

fn FdConfigFlags.zero() FdConfigFlags

fn FdEventType.from() FdEventType

fn FdEventType.zero() FdEventType

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
}
