Hello,
I have a C program that takes anywhere from 5 to 100 arguments and I'd like to run it from a script that makes sure it doesnt take too long to execute. If the C program takes more than 5 seconds to execute, i would like the shell script to kill it and return a short message to the user. ... (3 Replies)

rt_timer_add
RT_TIMER(9) BSD Kernel Developer's Manual RT_TIMER(9)NAME
rt_timer, rt_timer_add, rt_timer_queue_create, rt_timer_queue_change, rt_timer_queue_destroy, rt_timer_remove_all -- route callout functions
SYNOPSIS
#include <net/route.h>
struct rttimer_queue *
rt_timer_queue_create(time_t timeout);
void
rt_timer_queue_change(struct rttimer_queue *q, time_t timeout);
void
rt_timer_queue_destroy(struct rttimer_queue *q, int destroy);
int
rt_timer_add(struct rtentry *rt, void(*f)(struct rtentry *, struct rttimer *), struct rttimer_queue *q);
void
rt_timer_remove_all(struct rtentry *rt);
DESCRIPTION
The rt_timer functions provide a generic route callout functionality. They allow a function to be called for a route at any time. This was
originally intended to be used to remove routes added by path MTU discovery code.
For maximum efficiency, a separate queue should be defined for each timeout period. For example, one queue should be created for the 10
minute path MTU discovery timeouts, another for 20 minute ARP timeouts after 20 minutes, and so on. This permits extremely fast queue manip-
ulations so that the timeout functions remain scalable, even in the face of thousands of route manipulations per minute.
It is possible to create only a single timeout queue for all possible timeout values, but doing so is not scalable as queue manipulations
become quite expensive if the timeout deltas are not roughly constant.
The rt_timer interface provides the following functions:
rt_timer_queue_create(time_t timeout)
This function creates a new timer queue with the specified timeout period timeout, expressed in seconds.
rt_timer_queue_change(rttimer_queue *q, time_t timeout)
This function modifies the timeout period for a timer queue. Any value, including 0, is valid. The next time the timer queue's
timeout expires (based on the previous timeout value), all entries which are valid to execute based on the new timeout will be exe-
cuted, and the new timeout period scheduled.
rt_timer_queue_destroy(rttimer_queue *q, int destroy)
This function destroys a timeout queue. All entries are removed, and if the destroy argument is non-zero, the timeout action is
performed for each entry.
rt_timer_add(struct rtentry *rt, void(*f)(struct rtentry *, struct rttimer *), struct rttimer_queue *q)
This function adds an entry to a timeout queue. The function f will be called after the timeout period for queue q has elapsed. If
f is NULL the route will be deleted when the timeout expires.
rt_timer_remove_all(struct rtentry *rt)
This function removes all references to the given route from the rt_timer subsystem. This is used when a route is deleted to ensure
that no dangling references remain.

The rt_timer interface appeared in NetBSD 1.4.
AUTHORS
This interface is roughly based on (but, alas, not compatible with) one designed by David Borman of BSDI. This implementation is by Kevin
Lahey of the Numerical Aerospace Simulation Facility, NASA Ames Research Center.
CODE REFERENCES
The rt_timer interface is implemented in sys/net/route.h and sys/net/route.c.
