__gnu_cxx::__mt_alloc(3cxx)

__gnu_cxx::__mt_alloc3cxx

This is a fixed size (power of 2) allocator which - when compiled with thread support - will maintain one freelist per size per thread plus a global one. steps are taken to limit the per thread freelist sizes (by returning excess back to the global list).

Usage

#include <mt_allocator.h>

Inherits __gnu_cxx::__mt_alloc_base< _Tp >.
