Consider the following code:

1  int fork(void) {
2    struct proc *np;
3    struct proc *curproc = myproc();
4    np->pgdir = copyuvm(curproc->pgdir, curproc->sz);
5    *np->tf = *curproc->tf;
6    np->tf->eax = 0;
7    for(int i = 0; i < NOFILE; i++)
8      if(curproc->ofile[i])
9        np->ofile[i] = filedup(curproc->ofile[i]);
10    np->state = RUNNABLE;
11    return np->pid;
12 }
