RT_TIMER_ADD(9) FreeBSD Kernel Developer's Manual RT_TIMER_ADD(9) 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. SEE ALSO route(4), route(9) FreeBSD 14.1-RELEASE-p8 June 20, 2023 FreeBSD 14.1-RELEASE-p8
