朋友的作品，linux下的结构化共享内存，数据结构的设计比较巧妙，学习共享内存和数据结构可参考-friend works, linux under the structure of shared memory, data structures rather clever design. Learning shared memory and data structures can refer to

指针是C和C++语言编程中最重要的概念之一，也是最容易产生困惑并导致程序出错的问题之一。利用指针编程可以表示各种数据结构, 通过指针可使用主调函数和被调函数之间共享变量或数据结构，便于实现双向数据通讯；并能像汇编语言一样处理内存地址，从而编出精练而高效的程序。指针极大地丰富了Ｃ和C++语言的功能。-Pointer is a C and C++ Language programming in the concept of one of the most important and most eas
