[pool] Does Simple Segregated Storage support arrays?
The documentation at file://localhost/C:/Boost/libs/pool/doc/concepts.html says: "Each of the chunks in any given block are always the same size. This is the fundamental restriction of Simple Segregated Storage: you cannot ask for chunks of different sizes." Okay, but can I ask for more than one chunk of the same size - for an array? Boris

With the boost interface you can use malloc_n(), though freelists aren't meant for arrays. In fact, malloc_n() will fail if it doesn't find an obviously contiguous chunk. Common usage of a freelist will make the freelist non-contiguous so you probably want to look elsewhere.

Thanks for your answer! I'm using boost::pool currently which doesn't provide malloc_n(). There is only ordered_malloc(n). But as I understand now from your answer it won't help much either as there is no support for arrays in Boost Pool. Is this correct? Boris
