socket_mcloop4(3)

💖 socket_mcloop4 — like, the multicast loopback girlie 💖

okay so bestie, we're in the Library Functions Manual section and today's main character is socket_mcloop4(3). she's tiny. she's iconic. she controls whether your multicast packets get to hang out with themselves on the same host. let's get into it 🫶

✨ NAME ✨

socket_mcloop4 — set multicast loopback

🌸 SYNTAX 🌸

#include <libowfat/socket.h>

int socket_mcloop4(int s,char loop);

🦋 DESCRIPTION 🦋

okay so here's the tea ☕ — socket_mcloop4 activates multicast loopback for the socket s when loop is non-zero, and deactivates it otherwise. that's it. that's the whole vibe.

and like, why do you care? because when loopback is activated, packets sent on this socket will be received on the same host. it's giving "she's her own audience" energy. no cap ✨

if something goes wrong, socket_mcloop4 returns -1, and it sets errno appropriately. so if you see that -1, don't panic, just check your errno and handle it, bestie 😭
