Comment on Tutorial : Using free() Function in C By Daniel Malcolm
Can you tell me what will happen when I use a free function call to release the memory allocated to a memory block on ONE of the MULTIPLE pointers pointing to that memory block, eg

void *ptr1,*ptr2,*ptr3;
ptr1=ptr2=ptr3=malloc(1000);
free(ptr1);

in this case, what will happen if I try to access ptr2 and ptr3, and for that matter, ptr1, before I have assigned NULL to them, and after the above code?
