Dynamic memory management

在下面章节中，对它的"dynamic memory management"进行了论述。

II. Standard Contents # 4. Support # Dynamic Memory

In C++98 there are six flavors each of operator new and operator delete

NOTE:

主要讲述operator new、operator delete的API

II. Standard Contents # 6. Utilities # Memory

Memory contains three general areas.

First, function and operator calls via new and delete operator or member function calls.

Second, allocation via allocator.

Finally, smart pointer and intelligent pointer abstractions.

Extension Allocators

Table B.6. Extension Allocators

Allocator (3.4)	Header (3.4)	Allocator (3.[0-3])	Header (3.[0-3])
__gnu_cxx::new_allocator<T>	<ext/new_allocator.h>	std::__new_alloc	<memory>
__gnu_cxx::malloc_allocator<T>	<ext/malloc_allocator.h>	std::__malloc_alloc_template<int>	<memory>
__gnu_cxx::debug_allocator<T>	<ext/debug_allocator.h>	std::debug_alloc<T>	<memory>
__gnu_cxx::__pool_alloc<T>	<ext/pool_allocator.h>	std::__default_alloc_template<bool,int>	<memory>
__gnu_cxx::__mt_alloc<T>	<ext/mt_allocator.h>
__gnu_cxx::bitmap_allocator<T>	<ext/bitmap_allocator.h>

II. Standard Contents # 6. Utilities # Memory # Allocators

III. Extensions # 19. The mt_allocator

This allocator is tunable, very flexible, and capable of high-performance.

III. Extensions # 20. The bitmap_allocator

csdn gnu c++的allocator

1.gnu c++中的allocator类型

array_allocator

bitmap_allocator(和mfc中的bitmap无关)

malloc_allocator

mt_allocator(多线程)

new_allocator

extptr_allocator

debug_allocator

pool_allocator

throw_allocator

其中new_allocator与pool_allocator在STL内存分配allocator介绍过。
