typedef struct _NETWORKINFO {
  BYTE PermanentAddr[6];

  ADDRESS OtherAddress;
  DWORD LinkSpeed;
  DWORD MacType;
  DWORD MaxFrameSize;
  DWORD Flags;
  DWORD TimestampScaleFactor;
  BYTE NodeName[32];
  BOOL PModeSupported;
  BYTE Comment[ADAPTER_COMMENT_LENGTH];
} NETWORKINFO, 
 *LPNETWORKINFO;

Members

  • PermanentAddr
    Permanent MAC address.

  • CurrentAddr

  • TimestampScaleFactor
    For example, a value of 1 indicates 1/1 ms, 10 indicates 1/10 ms, 100 indicates 1/100 ms, and so on.

  • NodeName
    Name of remote workstation.
