__gnu_cxx::__mt_alloc< _Tp, _Poolp >(3cxx) __gnu_cxx::__mt_alloc< _Tp, _Poolp >(3cxx)

NAME

__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).

SYNOPSIS

#include <mt_allocator.h>

Inherits __gnu_cxx::__mt_alloc_base< _Tp >.
