Hello,

How many child processes are actually created when running this code ?

#include <signal.h>
#include <stdio.h>

int main () {
int i ;
setpgrp () ;
for (i = 0; i < 10; i++) {
if (fork () == 0) {
if ( i & 1 ) setpgrp () ;
printf ("Child id: %2d, group: %2d\n", getpid(), getpgrp()) ;
sleep (60) ;
exit (0) ;
}
}
kill (0, SIGINT) ;
return 0 ;
}
