NAME
       sockaddr_in6, in6_addr - IPv6 socket address

LIBRARY
       Standard C library (libc)

SYNOPSIS
       #include <netinet/in.h>

       struct sockaddr_in6 {
           sa_family_t     sin6_family;    /* AF_INET6 */
           in_port_t       sin6_port;      /* Port number */
           uint32_t        sin6_flowinfo;  /* IPv6 flow info */
           struct in6_addr sin6_addr;      /* IPv6 address */
           uint32_t        sin6_scope_id;  /* Set of interfaces for a scope */
       };

       struct in6_addr {
           uint8_t   s6_addr[16];
       };
