部分代码参考devcon,这个帖子的目的就是为了让大家少踩坑
这个代码是启用禁用的PCI网卡的设备,不要ctrl c, ctrl v,读懂可以自行修改,使用vs2010说找不到 cfgmgr32.lib,
正常的确实找不到,在 C:\windows\system32\cfgmgr32.dll 拷贝到一个目录
使用 pexports(mingw工具) :pexports -o cfgmgr32.dll > cfgmgr32.def
导出cfgmgr32.dll 的符号表def
然后使用 lib : lib /DEF:cfgmgr32.def /MACHINE:X64
OK,这样就生成了cfgmgr32.lib
编译的时候选上就ok了,把cfgmgr32.lib放在代码同一个目录
