sockaddr_in6(3type)

💖 sockaddr_in6 — the IPv6 socket address glow-up 💖

okay bestie, so this is the manual page for sockaddr_in6 (that's the man page name, sockaddr_in6(3type) if you're keeping score ✨). It's the 3type page, meaning it's all about types — the little structs you pass around when you're doing IPv6 socket things. Let's get into it, no cap.

🌸 NAME 🌸

sockaddr_in6, in6_addr — IPv6 socket address

---

📚 LIBRARY 📚

Standard C library (libc) — the classic, the icon, the one that's just there 🫶

---

✨ 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];
};

literally just two structs and a dream 💅

🦋 DESCRIPTION 🦋

• sockaddr_in6 — Describes an IPv6 Internet domain socket address. it's giving "here is where I live on the IPv6 internet, respectfully" 🏠✨
• in6_addr — Contains a 128-bit IPv6 address, stored in network byte order. yes bestie, network byte order, do NOT forget that or you will be sad 😭

👑 STANDARDS 👑

POSIX.1-2024. we're standardized, we're official, we're that girl 🎀

---

💫 HISTORY 💫

POSIX.1-2001. been iconic since the early 2000s, fr fr ⭐

🫶 reminder: all the literal stuff up there — the field names, the types, AF_INET6, uint8_t s6_addr[16] — is exactly what you type. don't freestyle it. iykyk 💀
