IP_ADAPTER_ANYCAST_ADDRESS_XP structure (iptypes.h)
The IP_ADAPTER_ANYCAST_ADDRESS structure stores a single anycast IP address in a linked list of addresses for a particular adapter.
Syntax
typedef struct _IP_ADAPTER_ANYCAST_ADDRESS_XP {
union {
ULONGLONG Alignment;
struct {
ULONG Length;
DWORD Flags;
};
};
struct _IP_ADAPTER_ANYCAST_ADDRESS_XP *Next;
SOCKET_ADDRESS Address;
} IP_ADAPTER_ANYCAST_ADDRESS_XP, *PIP_ADAPTER_ANYCAST_ADDRESS_XP;
Members
Alignment
Type: ULONGLONG
Reserved. Used by the compiler to align the structure.
Length
Type: ULONG
The length, in bytes, of this structure.
Flags
Type: DWORD
The flags for this anycast IP address.
The following table shows possible values. These constants are defined in the Iptypes.h header file.
| Value | Meaning |
|---|---|
|
The IP address is legal to appear in DNS. |
|
The IP address is a cluster address and should not be used by most applications. |
Next
Type: struct _IP_ADAPTER_ANYCAST_ADDRESS*
A pointer to the next anycast IP address structure in the list.
Address
Type: SOCKET_ADDRESS
The IP address for this anycast IP address entry. This member can be an IPv6 address or an IPv4 address.
Remarks
The IP_ADAPTER_ADDRESSES structure is retrieved by the GetAdaptersAddresses function. The FirstAnycastAddress member of the IP_ADAPTER_ADDRESSES structure is a pointer to a linked list of IP_ADAPTER_ANYCAST_ADDRESS structures.
The SOCKET_ADDRESS structure is used in the IP_ADAPTER_ANYCAST_ADDRESS structure. On the Microsoft Windows Software Development Kit (SDK) released for Windows Vista and later, the organization of header files has changed and the SOCKET_ADDRESS structure is defined in the Ws2def.h header file which is automatically included by the Winsock2.h header file. On the Platform Software Development Kit (SDK) released for Windows Server 2003 and Windows XP, the SOCKET_ADDRESS structure is declared in the Winsock2.h header file. In order to use the IP_ADAPTER_ANYCAST_ADDRESS structure, the Winsock2.h header file must be included before the Iphlpapi.h header file.
