🎀 NAME 🎀

socket_getifname — get interface name 💅

Okay bestie, this is the socket_getifname(3) page, living its best life in the Library Functions Manual. Let's get into it fr fr.

✨ SYNTAX ✨

#include <libowfat/socket.h>

const char* socket_getifname(uint32 interface);

🦋 DESCRIPTION 🦋

So socket_getifname is the function that returns the symbolic interface name for a network interface number. It's giving "what's your name, interface bestie?" 🫶

The returned char* is a static buffer in the libc. 🚨 Not me warning you: if you query the name for more than one interface, you have to save the name before calling socket_getifidx again. That buffer is shared, so it's not gonna stay cute forever.

If something goes wrong, socket_getifname returns "[unknown]". 😭

Save that name before you call again, periodt. The static buffer is not here to play. 💀

👑 SEE ALSO 👑

And that's the whole vibe, bestie. This page is socket_getifname(3), and the footer is just socket_getifname(3) — no extra source/version/date tea, just the name, iconic behavior only. 💖✨
