◆ ami_schedule()

nserror ami_schedule	(	int	t,
		void()(void p)	callback,
		void *	p
	)

Schedule a callback.

Parameters

t	interval before the callback should be made / ms
callback	callback function
p	user parameter, passed to callback function

Returns: NSERROR_OK on sucess or appropriate error on faliure

The callback function will be called as soon as possible after t ms have passed.
