		struct callback *	cb
	)

References event_methods::add_idle, event_idle::cb, and require_method2.

event_add_timeout()

struct event_timeout* event_add_timeout	(	int	timeout,
		int	multi,
		struct callback *	cb
	)

Add an event timeout

Parameters

the	timeout itself in msec
multi	0 means that the timeout will fire only once, 1 means that it will repeat
the	callback to call when the timeout expires

Returns

the result of the event_methods.add_timeout() call
