child process

[karabaja4]

hello

i need some help with my program. here is the code i can't figure out:

int main() {

...

if ((pid[1] = fork()) == 0) {
     printf("Running...");
     system("<run some infinite program>");
     exit(0);
}

...

kill(pid[1], 9);
wait(NULL);
return 0;
}

child doesn't seem to end with kill(). at the end of program i get this on output:

... some program output...

sh: line 1:  <pid> Terminated              <child program>

what i don't understand is how to run infinite program as a child process and then end it clean with parent without any messages? thanks for your help.

btw, im using arch. on ubuntu, the "Terminated" message doesn't show up.

Make the child process fork() again and get it to write its PID into a known file. The parent can reap its child and kill the grandchild but sending the signal to the PID read from the file.
