Function Documentation

kl_event_init()

int kl_event_init

(

KlEventLoop *

loop

)

Initialize the platform event loop (epoll/kqueue/io_uring).

kl_event_add()

int kl_event_add	(	KlEventLoop *	loop,
		int	fd,
		KlEventMask	mask,
		void *	udata
	)

Register a file descriptor for events.

kl_event_mod()

int kl_event_mod	(	KlEventLoop *	loop,
		int	fd,
		KlEventMask	mask,
		void *	udata
	)

Modify the event mask for a registered fd.

kl_event_del()

int kl_event_del	(	KlEventLoop *	loop,
		int	fd
	)

Remove a file descriptor from the event loop.

kl_event_wait()

int kl_event_wait	(	KlEventLoop *	loop,
		KlEvent *	out,
		int	max,
		int	timeout_ms
	)

Wait for events.

Parameters

loop	Event loop instance.
out	Array to receive ready events.
max	Maximum events to return.
timeout_ms	Timeout in milliseconds (-1 for infinite).

Returns

Number of ready events, or -1 on error.

kl_event_close()

void kl_event_close

(

KlEventLoop *

loop

)

Close and clean up the event loop.
