Basic Fork Question

["Asim Kadav" <linkasim@xxxxxxxxx>]

Hi,

Process A has a memory allocated and memory pointer x pointing to that memory.
I fork process B from a running process A.B gets a new copy of the
memory and the pointer.However, printing x in A and B points to the
same memory location(though actually differnt physical memory
locations).What is the concept of VM here.Can anyone kindly explain ?

=======================
For eg. :

[root@XXXXX]# cat test.c
#include <stdio.h>

main ()
{
        char a;
        a='b';
        fork();
        a='c';
        printf ("%x\n",&a);
}


[root@XXXXXX]# ./a.out
