💖 socket_mcjoin6(3) — bestie's guide to joining an IPv6 multicast group 💖

okay so literally welcome to socket_mcjoin6(3), from the Library Functions Manual, no cap. this is the lil function that gets you into an IPv6 multicast group, and honestly? it's giving main character energy. let's go. 🦋

✨ NAME ✨

socket_mcjoin6 — join a multicast group 💅

🌸 SYNTAX 🌸

bestie, you gotta include this first, fr fr:

#include <libowfat/socket.h>

int socket_mcjoin6(int s,const char groupip[16],uint32 interface);

like. that's the whole vibe. copy it exactly, don't be out here renaming stuff. 🙈

🎀 DESCRIPTION 🎀

so socket_mcjoin6 joins the IPv6 multicast group groupip on interface. that's it. that's the whole job. iconic behavior honestly. 🌈

if something goes wrong, socket_mcjoin6 returns -1, setting errno appropriately. so like, check your errno, bestie, it's literally telling you what happened. 💀

lowkey important: -1 is the "nope, didn't work" signal, and errno is the receipts. always peek at it. ✨

and that's the whole page, bestie. mwah. this lil beauty lives in the Library Functions Manual as socket_mcjoin6(3), so go forth and multicast responsibly. periodt. 💅🎀🦋
