c++ 32位 64位 获得进程peb的方法

基于上一篇文章，大概了解了peb的获取方法，但是那个方法只能获得当前进程的PEB，不能获得其他的进程的PEB。根据那个思想，获得其他进程PEB则需要注入，得到进程信息，然后进程间通信，将信息返回来，经过考虑，这个方法太复杂。

下面介绍的方法是 用了一个未公开的函数NtQueryInformationProcess，获得进程信息，然后去读对方进程ReadProcessMemory。

结构体是使用的一个模板，从别处借鉴的

    return 0;
}
有了PEB 则可以获得进程的各种信息，比如：模块、完整路径、命令行、环境变量、默认堆等等，参照结构体可得。

如何对PEB结构体不是很清楚，可以用windeg调试一下，attach到进程，然后使用!peb命令。
