SOCKET_ACCEPT4_SETCLOSEONEXEC(3)

✨ socket_accept4_setcloseonexec — the "accept it AND make it close-on-exec" glow-up ✨

okay bestie, settle in, we're in the Library Functions Manual and this one is a lil function from libowfat that does exactly what its very long name says 💅

🌸 NAME 🌸

socket_accept4_setcloseonexec — accept an IPv4 TCP connection on a socket and set it to close on exec

🦋 SYNTAX 🦋

#include <libowfat/socket.h>

int socket_accept4_setcloseonexec(int s,char ip[4],uint16 *port);

💖 DESCRIPTION 💖

so here's the tea, bestie: this is functionally equivalent to calling socket_accept4 and then calling io_closeonexec on the socket that comes back. literally the same outcome, no cap.

but however — and this is the iconic part — it may save you a syscall or two, and in the process it avoids a race condition. like, she's doing the same thing but she's doing it smarter. main character energy fr fr 🔥

🎀 EXAMPLE 🎀

#include <libowfat/socket.h>

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

s = socket_tcp4();
socket_bind4(s,ip,p);
socket_listen(s,16);
socket_accept4_setcloseonexec(s,ip,&p);

look at her go 😭 setting up a socket, binding, listening, then accepting and setting close-on-exec in one lil move. obsessed.
