Hi,

I am working on a project, where the requirement is to share memory between processes. I have been reading at the boost::pool documentation.

But unfortunately I suspect that I can’t use it very easily.

Basically, what I want to do is pre-allocate a large fixed size memory segment using mmap, and hand that memory over to pool. The pool should allocate memory from this segment. However I can’t find such an interface for pool.

I know that you can write a UserAllocator, but, I can not write one for shared memory. Dynamic nature of UserAllocator would mean maintaining free block myself, which is precisely what I wanted to avoid at the first place.  

Is it possible to use the pool interface to achieve this?

If yes how? If not, can you suggest an alternate package or something?

Or, Am I missing something? Please help.

Regards,
