I think I finally have a grasp on the basics of the boost:interprocess library, and I've been using it successfully when dealing with relatively simple classes that contain a few member variables that are all standard data types.
However, I am now faced with the problem of pushing a rather complex class out into interprocess shared memory and I'm having no luck at all. I'm hoping someone here can help (or can steer me towards an alternate solution). Stripping it down to what I hope are the basics, I have something along these lines:
You can't share any structure that contains raw pointers, because shared memory is mapped in different address in each process. So you need to replace every member with boost.interprocess alternatives. And if those structures are filled by GNu Scientifice Library, pointers would point to process-local memory (malloc-heap) and that memory isn't shareable with other processes. Best, Ion
