    There are two processes... One process(process 1) has a pointer to a variable in the other process(process 2)... Now, can the variable be updated using this pointer in process 1?

    i f the processes do not have shared memory,then the variable cannot be updated through the pointer,

    Also, if they have shared memory than also pointer address has to be offset by certain number based on how "mmap" maps it in 2 different processes.
