return value by do_fork()!!


hi all,

A small query.

I'm going through the code of do_fork().[kernel 2.4.16] fork.c

Since fork() returns the pid of child to parent when it returns & child get a
return value of zero.

After going through the code, its clear that the 'retval' is made equal to the
new pid (i.e of child)
=============
retval = p->pid;
=============
so that parent gets the pid of child.

But how does child gets a return value of zero?

I'm not clear about this...can anyone help me out.
 
TIA

Regards
Ketan
