SOCKADDR_IN6_W2KSP1 structure (ws2ipdef.h)
The SOCKADDR_IN6 structure specifies a transport address and port for the AF_INET6 address family.
Syntax
typedef struct sockaddr_in6_w2ksp1 {
short sin6_family;
USHORT sin6_port;
ULONG sin6_flowinfo;
struct in6_addr sin6_addr;
ULONG sin6_scope_id;
} SOCKADDR_IN6_W2KSP1, *PSOCKADDR_IN6_W2KSP1, *LPSOCKADDR_IN6_W2KSP1;
Members
sin6_family
The address family for the transport address. This member should always be set to AF_INET6.
sin6_port
A transport protocol port number.
sin6_flowinfo
The IPv6 flow information.
sin6_addr
An IN6_ADDR structure that contains an IPv6 transport address.
sin6_scope_id
A ULONG representation of the IPv6 scope identifier that is defined in the sin6_scope_struct member.
Remarks
All of the data in the SOCKADDR_IN6 structure, except for the address family, must be specified in network-byte-order (big-endian).
The size of the SOCKADDR_IN6 structure is too large to fit in the memory space that is provided by a SOCKADDR structure. For a structure that is guaranteed to be large enough to contain a transport address for all possible address families, see SOCKADDR_STORAGE.
