Objects of MyType should be shared between processes in shared memory. I have no problem to put and extract the objects from shared space. But I'm struggling with the const char* pointers.

Is there a reason that you are prefering 'const char *' over C++ strings (either std::string or, more to the point, boost::interprocess::string? The latter are explicitly designed to live in shared memory, while std::string makes assumptions which break when shared across different process address spaces.

We just recently had a very closely related thread on this topic; it might be helpful to you:

http://thread.gmane.org/gmane.comp.lib.boost.user/72140

I included some working code as well as specific links into the Boost.Interprocess documentation.

Hope this helps!
