原创 程序入口函数和glibc及C++全局构造和析构
1，程序入口函数和初始化 操作系统在装载可执行文件后，将把控制权交付给运行库的程序入口函数。 因此，程序首先运行的代码并不是main函数，而是负责为main函数执行创造环境，并负责调用main的入口函数（Entry Point）。main函数返回的值也会被这个入口函数所记录，然后调用atexit注册的函数，最终结束进程。 这样，程序的执行流程如下所示： 1，操作系统内核加载

转载在http://hi.baidu.com/darks00n/blog/item/4c019ec42ad0cdcad00060b1.html下面是一段win32 console程序(Debug版)的反汇编代码，很程式化的东西。本文不讨论这段码的具体作用，而是来学习下stos指令。stos((store into String)，意思是把eax的内容拷贝到目的地址。用法：stos dst，dst是一个目的地址，例如：stos dword ptr es:[edi]。dword ptr前缀告诉stos，一次拷贝
