💖 IF_FREENAMEINDEX(3POSIX) 💖

okay bestie, welcome to the POSIX Programmer's Manual, page IF_FREENAMEINDEX(3POSIX) — yes the manual name is literally in the title, she's that girl 💅

✨ PROLOG ✨

so like, this manual page is part of the POSIX Programmer's Manual. but heads up bestie 🫶 — the Linux implementation of this interface may differ (so if you're on Linux, go consult the corresponding Linux manual page for the deets on Linux behavior), or honestly?? the interface may not even be implemented on Linux at all. vibe check accordingly 😭

🌸 NAME 🌸

if_freenameindex — free memory allocated by if_nameindex

🎀 SYNOPSIS 🎀

#include <net/if.h>

void if_freenameindex(struct if_nameindex *ptr);

🦋 DESCRIPTION 🦋

okay so here's the tea ☕ — the if_freenameindex() function shall free the memory allocated by if_nameindex(). that's literally her whole job, she's a cleanup icon 👑

the ptr argument shall be a pointer that was returned by if_nameindex(). like, don't just hand her any old pointer, she needs the specific one if_nameindex() gave you, no cap.

and after if_freenameindex() has been called?? the application shall not use the array of which ptr is the address. it's gone. deceased. don't touch it 🚫💀

⭐ RETURN VALUE ⭐

None. she gives you nothing back, and honestly? that's the point. no notes 💜
