πŸ’– socket_mcloop6 πŸ’–

okay bestie, so we're looking at a page from the Library Functions Manual β€” it's socket_mcloop6(3), and she's a tiny little icon but she does exactly one thing and she does it flawlessly. no notes. πŸ’…


✨ NAME ✨

socket_mcloop6 β€” set multicast loopback πŸŽ€


🌸 SYNTAX 🌸

#include <libowfat/socket.h>

int socket_mcloop6(int s,char loop);

like yes, that's the whole thing, she's short and she knows it πŸ¦‹


πŸ’œ DESCRIPTION πŸ’œ

so here's the tea, bestie: socket_mcloop6 turns multicast loopback on for the socket s when loop is non-zero, and turns it off otherwise. that's it. that's the whole job. main character behaviour honestly πŸ‘‘

and what does loopback actually mean here? it means if it's activated, packets you send on this socket will be received on the same host. yes, you heard that right β€” you send it, you receive it, it's giving self-love, it's giving "i am my own audience" 🫢✨

if something goes wrong, socket_mcloop6 returns -1 and sets errno appropriately. so like, always check your errno, bestie, she's trying to tell you something 😭

not me being emotionally invested in a return value πŸ’€ but fr fr, -1 + errno is the whole error story here, don't sleep on it.
