NETWORKINFO

The NETWORKINFO structure describes a NIC.

typedef struct _NETWORKINFO {
  BYTE PermanentAddr[6];
  BYTE CurrentAddr[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
  Current MAC address.

• OtherAddress
  Other address that support this (for example IP, IPX).

• LinkSpeed
  Link speed, in Mbps.

• MacType
  Media type.

• MaxFrameSize
  Maximum frame size allowed.

• Flags
  This parametere can be one of the following informational flags:

  Value	Meaning
  NETWORKINFO_FLAGS_PMODE_NOT_SUPPORTED	The network card does not support promiscuous mode, meaning that it will only capture traffic which is broadcast in nature or only involves the local machine.
  NETWORKINFO_FLAGS_RAS	This is a virtual network card that is a RAS (Remote Access Server) connection through a modem or another network card.
  NETWORKINFO_FLAGS_REMOTE_CARD	The network card is not on the local computer, but is capturing on a remote machine at the bequest of the local computer.
  NETWORKINFO_FLAGS_REMOTE_NAL	Obsolete; do not use.
  NETWORKINFO_FLAGS_REMOTE_NAL_CONNECTED	Obsolete; do not use.

• 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.

• PModeSupported
  NIC P-mode support indicator.

• Comment
  Adapter comment field.
