πŸ’– socket_bind4_reuse(3) πŸ’–

okay bestie, so this is a page from the Library Functions Manual and it's all about socket_bind4_reuse β€” yes the whole thing, we're doing this, grab a lil snack πŸ“


✨ NAME ✨

socket_bind4_reuse β€” set the local IP address and port of a socket

like... it literally just tells a socket "hey, this is your address and this is your port" πŸ’…


🌸 SYNTAX 🌸

first things first, you gotta pull in the header, no cap:

#include <libowfat/socket.h>

int socket_bind4_reuse(int s,char ip[4],uint16 port);

so it takes a socket s, an ip that's a char array of 4 (that's your IPv4 vibe, 4 bytes, iconic), and a port that's a uint16, and it hands you back an int. periodt.


πŸ¦‹ DESCRIPTION πŸ¦‹

so what does it do, you ask? socket_bind4_reuse sets the local IP address and TCP/UDP port of a TCP/UDP socket s to ip and port respectively. that's it. that's the job. main character energy fr fr.

now here's the cute part πŸ‘‘ β€” 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. so you can just vibe and let the OS handle it, no stress 🫢

normally socket_bind4_reuse returns 0. if anything goes wrong, it returns -1 and sets errno appropriately, so you can go peek at what happened. πŸ’€

and here's the tea β˜• β€” unlike socket_bind4, this function will also tell the operating system that the address is to be reused soon, which turns off the normal pause before this IP and port can be bound again. so it's like the same thing but speedier, iykyk πŸ”₯

🌈 EXAMPLE 🌈

here's how you'd actually use it, bestie:

#include <libowfat/socket.h>

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

s = socket_tcp4();
socket_bind4_reuse(s,ip,p);
socket_connect4(s,ip,p);

make a TCP4 socket, bind it with reuse, connect it. slay. ✨
