python3 调用windowsAPI 获取网卡信息

Cool_Breeze

缺失4个字节 198. 和 255.
不知道哪里出了问题！
解决了 ('Description', ctypes.c_char*132),
将 132 改成 128 就好了
还是不对， mac地址不对了

终于解决了！

  typedef struct _IP_ADDR_STRING {
    struct _IP_ADDR_STRING *Next;  //1
    IP_ADDRESS_STRING IpAddress; //2
    IP_MASK_STRING IpMask; //3
    DWORD Context; //4
  } IP_ADDR_STRING,*PIP_ADDR_STRING;

我python里面定义的结构体顺序错了！（修改后正确）
