Ion-

There is some missing documentation for shmem.
basic_named_shared_object is missing the member functions that are in
basic_named_object_impl. I wouldn't have brought this up except that
I've got a question about some of them. (Actually, Google's cache has
some documentation on some of this. Is that out of date?)

When you create a named_shared_object, your examples do so on the
stack in the creating (or opening) process. From looking at the code,
it appears that a named_shared_object::segment_manager is created in
the shared memory. These segment_managers are also undocumented, but
it appears that they do many (all?) of the things that can be done
through the named_shared_object.

I'm hoping to use one of these. I'm hoping to store an offset_ptr to
the segment_manager in a shared object that I'm creating. The object
would then be able to use the segment_manager to allocate and
deallocate shared memory.

Is that the correct use for these things? Am I going down the wrong
track somewhere?
