Boost C++ Libraries

...one of the most highly regarded and expertly designed C++ library projects in the world. — Herb Sutter and Andrei Alexandrescu, C++ Coding Standards

Header <boost/pool/pool.hpp>

Provides class pool: a fast memory allocator that guarantees proper alignment of all allocated chunks, and which extends and generalizes the framework provided by the simple segregated storage solution. Also provides two UserAllocator classes which can be used in conjuction with pool.

namespace boost {
  struct default_user_allocator_malloc_free;
  struct default_user_allocator_new_delete;
}
