Re: Data migration

Thanks for the answer, Thats a very good pointer.


Instead of correcting it as soon as the data is recieved at the other,
I would like to do it as late as possible, to cut down on the initial
set up. So the way I am thinking is that I want to do it just before a
pointer dererefence.


correct(p)
*p++


The function would look up the current value of p, it will compare the
value with all the objects it can point to and find the object it is
pointing to. And then find the location of the object in the new
environment and do the appropriate correction. To enable the look up
using function correct(p), pointers wil be always be assigned
addresses from a hypothetical address space that is not used in any of
the address spaces.




My heap data is likely to be in a shared memory. So I dont have to
worry abt pointers to heap only data.




IS this somethng feasible ? if I assume ansi-aliasing conventions,
would that make this safe?
