For the following program, (1) sketch the corresponding process tree being sure to indicate any outputs and synchronization points, if they exist — and (2) write down the output it will produce when executed. int done = 0; void handler (int sig) { printf ("0"); done = 1; } main() { } pid_t pid; int status; signal (SIGUSR1, handler); if ((pid = fork()) EB 0) { while (!done) ; printf("1"); exit (2) ; } else { printf("3"); kill (pid, SIGUSR1); if (wait (&status) > 0) printf ("%d", WEXITSTATUS (status)); } if (done) printf("4"); else printf("5"); For the following program, (1) sketch the corresponding process tree being sure to indicate any outputs and synchronization points, if they exist — and (2) write down the output it will produce when executed. int done = 0; void handler (int sig) { printf ("0"); done = 1; } main() { } pid_t pid; int status; signal (SIGUSR1, handler); if ((pid = fork()) EB 0) { while (!done) ; printf("1"); exit (2) ; } else { printf("3"); kill (pid, SIGUSR1); if (wait (&status) > 0) printf ("%d", WEXITSTATUS (status)); } if (done) printf("4"); else printf("5");
