SOCKADDR_IN6_PAIR structure (ws2ipdef.h)
The SOCKADDR_IN6_PAIR structure contains pointers to a pair of IP addresses that represent a source and destination address pair.
Syntax
typedef struct _sockaddr_in6_pair {
PSOCKADDR_IN6 SourceAddress;
PSOCKADDR_IN6 DestinationAddress;
} SOCKADDR_IN6_PAIR, *PSOCKADDR_IN6_PAIR;
Members
SourceAddress
A pointer to an IP source address represented as a SOCKADDR_IN6 structure. The address family is in host byte order and the IPv6 address, port, flow information, and zone ID are in network byte order.
DestinationAddress
A pointer to an IP source address represented as a SOCKADDR_IN6 structure. The address family is in host byte order and the IPv6 address, port, flow information, and zone ID are in network byte order.
Remarks
The SOCKADDR_IN6_PAIR structure is defined on Windows Vista and later.
Any IPv4 addresses in the SOCKADDR_IN6_PAIR structure must be represented in the IPv4-mapped IPv6 address format which enables an IPv6 only application to communicate with an IPv4 node. For more information on the IPv4-mapped IPv6 address format, see Dual-Stack Sockets.
The SOCKADDR_IN6_PAIR structure is used by the CreateSortedAddressPairs function.
Note that the Ws2ipdef.h header file is automatically included in Ws2tcpip.h header file, and should never be used directly.
