The Boost.Pool class describes a pool of buffer, pool whose size grows as needed.
This is very convenient but there usage cases where the pool should not perform any dynamic memory allocation, i.e. the maximum number of simultaneously required buffers is known at initialization. I have hence defined a simple class 'static_pool' (see below), which (i) allocate all requested buffers at initialization; (ii) fails (returns null) if more buffers are being asked for at runtime.
Does such a class has its place within the Boost Pool library ?

I also need entirely static pools that allocate memory at *compile* time via template parameter. I use this kind of pool as the basis for memory allocation in embedded microcontroller projects. So I would actually need one-shot allocation (as you describe) as well as compile-time allocation. I have always written my own pools for this. I might be nice to get one *off the rack* from boost. Good luck. Best regards, Chris.
