Windows驱动开发：取进程模块的函数地址源码
在笔者上一篇文章《Windows驱动开发：内核取应用层模块基地址》中简单为大家介绍了如何通过遍历PLIST_ENTRY32链表的方式获取到32位应用程序中特定模块的基地址，由于是入门系列所以并没有封装实现太过于通用的获取函数，本章将继续延申这个话题，并依次实现通用版GetUserModuleBaseAddress()取远程进程中指定模块的基址和GetModuleExportAddress()取远程进程中特定模块中的函数地址，此类功能也是各类安全工具中常用的代码片段。首先封装一个lyshark.h头文件，此类头文件中的定义都是微软官方定义好的规范，如果您想获取该结构的详细说明文档请参阅微软官方，此处不做过多的介绍。
