The code below is not a typical way of handling fork() and pipe), but to test your understanding of their behaviors. The code works fully and you can try to run it.

int a = 0; int b = 0, intc, d;

int pfd[2]; // pipe file descriptor

void parent_function (int arg)

{ a = 2; b= 3; c=7; d= 8;

pipe (pfd):

if (arg I= 0) write (pfd[1], &c , sizeof(int)); else write (pfd[1]. &d sizeof(int)); printf ("parent: %d,%din", a, b);

close (pfd[1]);

read (pfdrOl. &b sizeof(int)). printf ("child:%d,%din", a, b);

close (ofdrOl):

void main ()

[int ret = fork 0);

parent_function (ret);

if (ret == 0) child_function ();

Give the outputs of the child process. Put each line of output in the corresponding box below. Your answer for each line should contain no space (e.g., parent:2,0), (e. g, child:2,0).
