Killing a process that takes too long

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. If it takes less than 5 seconds, the program spits out a short message to standard out, then i'd like the script to stop normally.

Can a script help do this?, or am I going to have to rewrite the C program to handle this?

The problem is, it seems like i would need a multi-threaded shell script?...I'm really not sure how to go about doing this. Any help would be greatly appreciated. I'm running bash 3.00.15 on redhat.

Thanks

NAME
script - make record of a terminal session SYNOPSIS
script [-a] [filename] DESCRIPTION
The script utility makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the record is saved in the file typescript. See WARNINGS. The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends when the forked shell exits or when Control-d is typed. OPTIONS
The following option is supported: -a Appends the session record to filename, rather than overwriting it. NOTES
script places everything that appears on the screen in filename, including prompts. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ |CSI |Enabled | +-----------------------------+-----------------------------+ SEE ALSO
attributes(5) WARNINGS
script can pose a security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a privileged user, that is, root. Be sure that typescript is not a link before running script. SunOS 5.11 30 Jan 2004 script(1)
