遇到的问题:
(1)EnumProcessModulesEx 遇到有些进程会出错,错误码为299。
参考:http://blog.csdn.net/anycell/article/details/3505864
原因:PEB的地址被设置在PebBaseAddress中。但是64位进程的PEB头地址是保存在64位长度的地址中的(比如上面说道的系统进程Services.exe),而32位进程的PEB头地址只有32位长度。运行在64位系统上32位应用程序是如何将64位的PEB地址转换成32位地址的呢?如果64位PEB地址的高32位为0,则转换不会出现任何问题。但如果高32位也包含地址信息,那么WOW64(Windows 32-bit on Windows 64-bit,windows 64位系统上兼容32位应用程序的技术,作为由32位向64位程序的过渡方案)只是简单的将低32位的PEB地址赋给32位应用程序中的PebBaseAddress变量,当然就会发生错误了!于是Windows就会出发error 299并返回失败。
解决办法:将编译的程序由32位改为64位即可。
(2)有3个进程open不了,提升权限也无效(“System Idle Process(pid=0)”、”System(pid=4)”、”audiodg.exe(pid=336)”)
暂无解决办法
