memcpy函数测试，在linux和VC编译器下面运行，效果不一样（不能重叠copy）。linux内核memmove函数实现。-memcpy function tests, and VC compiler in linux running below, the effect is the same. linux kernel memmove function implementation.

很好用的很简单的张孝祥数据结构配套代码，直接复制粘贴到VC里边即可使用-Good use of a very simple data structure supporting Auspicious code, copy and paste directly to the VC can be used inside
