Problem B. The program shown below uses the Pthreads API. What is the output from the program at LINE C and LINE P? Why? #include #include int value0 void *runner(void *param); /* the thread */ int main int argc, char argv]) pid _t pid; pthread t tid; pthread attr t attr pid = fork(); if (pid 0) { /* child process */ pthread_attr init(&attr); pthread create(&tid, &attr, runner, NULL); pthread_join(tid, NULL); printf"CHILD: value-%d", value):/* LINE C */ else if (pid >0) /*parent process* wait NULL); printf"PARENT: value d", value); /*LINE P*/ void *runner(void *param) { value 27, pthread_exit(0)
