This is vaguely DEC Unix related and, yes, it is derived from a
homework question (my wife's not mine). But something _is_ going on
that, when answered, will further my knowledge so:
The subject is process synchronization. They have a simple program that
looks like this:
#include <stdio.h>
int main()
{
int x;
printf("PID %d initial process \n", getpid() );
x = fork();
printf("PID %d terminates.\n", getpid() );
}
Parent tells its pid, creates a child and then both child and parent
display their pid and exits.
When run on a Sun machine the parent doesn't exit until the child is
done. When I run it on Intel Linux, Alpha Tru64 and Alpha OpenBSD the
parent terminates before the child. What is the Sun doing
differently than the others?
