Hi,

I am working on shared memory. I am successful in using it but I am trying
to optimize my code. I just want to know the differences between create_only
and open_or_create. As far as i know, create_only creates the shared memory
with given size, while open_or_create can open and create both. But If I use
open_or_create instead of create-only, i am getting interprocess exception.
Why?
Please help. Thanks in advance.
