//1.对齐空间分配//alignment对齐边界 2的幂//size 字节数void* storage = boost::alignment::aligned_alloc(alignment, size);//释放空间boost::alignment::aligned_free(storage);//2.对齐分配器allocator//遵循over-alignment的分配std::vector<int128_t, boost::alignment::aligned_allocator<int128_t> > ...
二、基本原理 1. 动态分配 C++11为class类型添加了增长对齐类型(over-alignment),但是C++标准库中的new运算符、表达式和默认的分配器、std::allocator并不支持为over-aligned的数据动态分...猜你喜欢BOOST C++ 之内存管理 ...Boost asio入门学习笔记 Timer1:使用一个同步计时器 所谓的同步,就是指t.wait必须...
为了避免这个问题,可以在在应用程序中创建一个内存块供asio异步IO操作使用,异步IO操作通过自定义接口 asio_handler_allocate 和 asio_handler_deallocate 来使用该内存块。该例子中使用到了 boost::aligned_storage<1024> storage_ 来管理原始内存。 cpp03 1//2//server.cpp3//~~~4//5//Copyright (c) 2003-2...
