SOCKADDR_IN6_PAIR structure

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.

Requirements
