Function Documentation

dpl_callout_init()

static void dpl_callout_init ( struct dpl_callout *  c, struct dpl_eventq *  q, dpl_event_fn *  e_cb, void *  e_arg  )

inlinestatic

Initialize a callout.

Callouts are used to schedule events in the future onto an event queue. Callout timers are scheduled using the dpl_callout_reset() function. When the timer expires, an event is posted to the event queue specified in dpl_callout_init(). The event argument given here is posted in the ev_arg field of that event.

Parameters

[out]	c	callout to initialize
[in]	q	event queue to queue event in
[in]	e_cb	callback function
[in]	e_arg	callback function argument
