Hi,
Maybe this is a little bit stupid from me but it
appears I got some problem killing an innocent child
process (I show the code below ...)
Got Cygwin from cygwin.com about 15 days ago...running
on Windows2000
If I call from my parent process a simple kill(pid)
then it doesn't stop the child process at all, or
maybe after more than one minute but I don't think
so...
If I send from my parent process a kill(pid,x) where x
is 1 or 9, then when I wait after in parent for child
termination with waitfunction I have a segmentation
fault during wait...
PS if parent is killed with Ctrl-C, I can kill child
then from shell with kill pid
Thanks for your help
Pierre

int times = 10;
int i;
pid=fork();
if (pid < 0){
return 1;
}
else if (pid == 0){ //Child
while(1){
sleep(5);
printf("Child\n");fflush(stdout);
}
return 0;
}
else{//Parent
for(i=1;i<=times;i++){
sleep(1);
printf("Parent\n");fflush(stdout);
}
printf("Killing Child (pid %d)\n",pid);
kill(pid); //Or kill(pid,1)
printf("Waiting for child to terminate\n");
wait(); //Seg Fault if kill(pid,1)
//Wait till tomorrow if kill(pid)
printf("Exiting\n");fflush(stdout);
return 0;
}
}
