socket_broadcast(3)

✨ socket_broadcast — the manual page ✨

okay so this one lives in the Library Functions Manual, bestie, and it's genuinely so simple you're gonna slay it 💅

🌸 NAME 🌸

socket_broadcast — flip a UDP socket into broadcast mode 📣✨

🎀 SYNTAX 🎀

#include <libowfat/socket.h>

int socket_broadcast(int s);

💖 DESCRIPTION 💖

so socket_broadcast sets the UDP socket s to broadcast mode. that's the whole vibe. 🦋

and like, this part matters, okay? socket_send4 and socket_send6 will fail to send packets to the broadcast address unless you call socket_broadcast before. like, before before. no cap. 🙈

normally socket_broadcast returns 0. iconic. flawless. no notes. ✨

but if anything goes wrong, it returns -1 and sets errno appropriately. so check your return values, babe, i'm begging 😭

🌈 EXAMPLE 🌈

#include <libowfat/socket.h>

int s;

if ((s=socket_udp6())==-1)
  strerr_die2sys(111,FATAL,"unable to create UDP socket: ");
if (socket_broadcast(s) == -1)
  strerr_die2sys(111,FATAL,"unable to set broadcast mode: ");

look at you go, setting up a socket and enabling broadcast and handling your errors like a whole main character 👑💜
