Memory Pools (mpool) are heap style objects that may be created on top of statically defined memory areas or by using memory pages obtained dynamically from the operating system. Standard heap type operations such as allocate, reallocate, and free are supported. An mpool may be created or destroyed at any time. Destroying an mpool is predicated upon no further references to mpool memory being possible.
