3/26/2014

This structure stores an IP prefix.

Syntax

typedef struct _IP_ADAPTER_PREFIX {
  union {
    ULONGLONG Alignment;
    struct {
      ULONG Length;
      DWORD Flags;
    };
  };
  struct _IP_ADAPTER_PREFIX* Next;
  SOCKET_ADDRESS Address;
  ULONG PrefixLength;
} IP_ADAPTER_PREFIX, *PIP_ADAPTER_PREFIX;

Members

• Alignment

• Length
  Length of this structure.

• Flags
  Index of the IPv4 interface with which these addresses are associated. Contains zero if IPv4 is not available on the interface.
