I was wrong. It looks like boost's development and my own development
simply overlap. It appears as though I merely reinvented the wheel on this one.
I often make this kind of mistake---charge ahead with my own
development before actually knowing what's there in the first place.
My methods simply parallel those of boost's fast_pool_allocator
(with a dummy Mutex template parameter) in combination with
boost's singleton_pool. So my code is very similar to boost's.
Sorry about that.
One other idea that may be of interest, though, is the concept
of "placing" a custom allocator and its associated pool at
a known physical address and granting these the one-shot allocation
character that you describe. I have used this technique in combination with
various sets of microcontroller registers to overly STL containers like a vector
on top of, say, the background readings from a hardware DMA.
In this way the DMA "fills up" your vector in a CPU-independent
fashion and the user can read the results from the underlying hardware
layer---properly packed in the container---with essentially zero cost.
I have not yet seen anyone else do this with the STL.
Best regards, Chris.
