@roy : yes , kind of , i didnt know the exact technical term for it. Not exactly PCB but process can maintain a lookup table for all the shared variable and there corresposing threads . or for every thread the shared variable. or ,may be in the thread itself, you can have a linked list pointer which points to all the shared variable list. Before terminating , get that address. I mean it is imagination, i suggested some ways but i exactly dont know what Windows or Unix employs to do the task.
