Use kill(). The syntax of the call is:

kill(pid, signum);

pid is the pid of the process to kill.  signum is how you want to signal the process.  If signum = 9, then it's an unconditional termination.  It's usually better to install a signal handler in your process so that it can terminate in an orderly fashion.
check out kill signum 3, 6, 9.
Basically it is safer to use the lower ones first rather then 9 straightaway.
