An "object pool" framework for minimally-fragmenting interlaced dynamic allocation and deallocation of dynamic memory objects in C.
In embedded and small-memory systems, excessive use of dynamically allocated
objects can cause heap fragmentation such that, despite there being sufficient
free space in the heap for an object, calls to malloc() and related functions
fail because no single block is large enough to fulfill the desired request.
This library provides an implementation of a smarter memory pool manager that combats this problem by minimizing the number of interlaced allocations, deallocations and reallocations at a slight expense in memory and CPU overhead. It supplies a low level interface for building custom allocators in cases where fine control is needed, a high level interface for the most common and simple use cases, and a macro interface for the easiest use case.
