NAME

rt_timer_add, rt_timer_remove_all, rt_timer_get_expire, rt_timer_queue_init, rt_timer_queue_change, rt_timer_queue_flush, rt_timer_queue_count — route timer queues interface

SYNOPSIS

#include <net/route.h>

int
rt_timer_add(struct rtentry *rt, struct rttimer_queue *queue, u_int rtableid);

void
rt_timer_remove_all(struct rtentry *rt);

time_t
rt_timer_get_expire(const struct rtentry *rt);

void
rt_timer_queue_init(struct rttimer_queue *rtq, int timeout, void (*func)(struct rtentry *, u_int));

void
rt_timer_queue_change(struct rttimer_queue *rtq, int timeout);

void
rt_timer_queue_flush(struct rttimer_queue *rtq);

unsigned long
rt_timer_queue_count(struct rttimer_queue *rtq);

DESCRIPTION

The rt_timer subsystem queues routing-related functions for asynchronous execution in the future.

rt_timer_add() allocates an rttimer_queue rtq to be called on rt using the timeout of queue. If an action already exists, it will be replaced with the new one.

rt_timer_remove_all() removes all timeouts associated with rt from all routing timer queues.

rt_timer_get_expire() returns the current expiry time in seconds.

rt_timer_queue_init() creates a timer queue with a timeout of timeout seconds.

rt_timer_queue_change() sets the timeout for rtq to timeout seconds.

rt_timer_queue_flush() removes all timeouts from the routing timer queue rtq, executes their associated callback and destroys it.

rt_timer_queue_count() returns the number of timers present in the queue rtq.

CONTEXT

rt_timer_add(), rt_timer_remove_all(), rt_timer_get_expire(), rt_timer_queue_init(), rt_timer_queue_change(), rt_timer_queue_flush() and rt_timer_queue_count() can be called during autoconf, from process context, or from interrupt context.

ERRORS

rt_timer_add() may fail with ENOBUFS if memory could not be allocated for the timeout.
