GetAdaptersAddresse Subnetzmaske

Hi weiß jemand wo meine Subnetzmsake versteckt ist wenn ich von der Funktion eine IP_ADAPTER_ADDRESSES struktur bekommen habe?

Meine ip hab ich bei
PIP_ADAPTER_UNICAST_ADDRESS FirstUnicastAddress;

gefunden aber sehe irgendwie keine maske ??

hier ist die komplete Sturktur:

typedef struct _IP_ADAPTER_ADDRESSES {
  union {
    ULONGLONG Alignment;
    struct {
      ULONG Length;
      DWORD IfIndex;
    };
  };
  struct _IP_ADAPTER_ADDRESSES       *Next;
  PCHAR                              AdapterName;

  IF_LUID                            Luid;
  SOCKET_ADDRESS                     Dhcpv4Server;
  NET_IF_COMPARTMENT_ID              CompartmentId;
  NET_IF_NETWORK_GUID                NetworkGuid;

  PIP_ADAPTER_DNS_SUFFIX             FirstDnsSuffix;
} IP_ADAPTER_ADDRESSES, *PIP_ADAPTER_ADDRESSES;

Die Subnetmaske holst du am besten mit GetIpAddrTable.

Auf meiner Homepage unter http://members.inode.at/anton.zechner/az/index.html
findest du einen IpSwicher. http://members.inode.at/anton.zechner/az/IpSwitcher.htm

In der Bibliothek findes du die Dateien NetFunctions.cpp/.h, mit der
Funktion NetGetIpAddresses(...) das sollte alles sein was du suchts.
