Function Documentation

add_fd_event()

void add_fd_event	(	event_system *	ev_sys,
		fd_event *	event,
		int	options
	)

Add a fd event to an event system. A event can only be in one event system at a time. (not thread safe)

Parameters

ev_sys	the event will be added to this event system
event	the event to add
options	set how the event should be triggered. (EV_READABLE | EV_WRITABLE | EV_CHANGE)

add_timed_event()

void add_timed_event	(	event_system *	ev_sys,
		timed_event *	event
	)

Add a timed event to an event system. A event can only be in one event system at a time. (not thread safe)

Parameters

ev_sys	the event will be added to this event system
event	the event to add

disable_fd_event()

void disable_fd_event

(

fd_event *

event

)

enables a fd event

Parameters

event

the event to enable

disable_timed_event()

void disable_timed_event

(

timed_event *

event

)

disables a timed event

Parameters

event

the event to disable

enable_fd_event()

void enable_fd_event

(

event

)

enables a fd event

Parameters

event

event	the event to add

remove_timed_event()

void remove_timed_event	(	event_system *	ev_sys,
		timed_event *	event
	)

Removes a timed event from its event system. (not thread safe)

Parameters

ev_sys	the event will be added to this event system
event	the event to add
