__gnu_cxx::__mt_alloc< _Tp, _Poolp > Class Template Reference

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). More...

Detailed Description

template<typename _Tp, typename _Poolp = __common_pool_policy<__pool, __thread_default>>
class __gnu_cxx::__mt_alloc< _Tp, _Poolp >

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).
