socket_bind4(3)

💖 socket_bind4 — bestie's guide to claiming your spot on the network 💖

okay so this is a page from the Library Functions Manual, and it's all about socket_bind4(3). if you've ever wanted your socket to have a literal address, this is the function. main character energy for your local IP fr fr. 🫶

✨ NAME ✨

socket_bind4 — set the local IP address and port of a socket 🎀

---

✨ SYNTAX ✨

#include <libowfat/socket.h>

int socket_bind4(int s,char ip[4],uint16 port);

no cap, that's the whole signature. she's simple, she's iconic. 💅

---

✨ DESCRIPTION ✨

so socket_bind4 sets the local IP address and TCP/UDP port of a TCP/UDP socket s to ip and port respectively. like, you're telling the universe "this is where I live now." 🏡✨

if the IP address is 0.0.0.0, the operating system chooses a local IP address for you. and if port is 0, the operating system chooses a port. lowkey the OS is being your wingman there. 😌

normally socket_bind4 returns 0. but if anything goes wrong, she returns -1 and sets errno appropriately. so yeah, check that return value bestie, don't just vibe past it. 💀

fr fr, -1 means something went sideways. errno is holding the receipts.

✨ EXAMPLE ✨

okay so here's the whole thing in action, and yes I'm keeping it exactly as-is because copy-paste is self-care:

#include <libowfat/socket.h>

int s;
char ip[4];
uint16 p;

s = socket_tcp4();
socket_bind4(s,ip,p);
socket_connect4(s,ip,p);

look at her go. bind then connect. the way that she just does that. 🔥

✨ SEE ALSO ✨

and that's the whole page, babes. this came to you straight from the socket_bind4(3) corner of the Library Functions Manual — same name up top, same name at the bottom, iconic from start to finish. go bind something responsibly. 🌈💖✨
