ICONV_CLOSE(3P)

🎀 ICONV_CLOSE(3P) — the POSIX Programmer's Manual, bestie edition 🎀

okay so this page lives in the POSIX Programmer's Manual, and it's ICONV_CLOSE(3P) if you wanna look it up by name.

💖 PROLOG 💖

so like, heads up before we even start:

This manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (consult the corresponding Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.

translation: this is the POSIX tea ☕, not necessarily the Linux tea. check your local page. it might not even exist on your box. it's giving "it depends" ✨

✨ NAME ✨

iconv_close — codeset conversion deallocation function

aka the little cleanup fairy 🧚 that says bye-bye to your conversion descriptor.

---

🌸 SYNOPSIS 🌸

#include <iconv.h>

int iconv_close(iconv_t cd);

look at her. one include, one function, one argument. minimal. iconic. 💅

---

🦋 DESCRIPTION 🦋

okay so here's the whole vibe: iconv_close() shall deallocate the conversion descriptor cd, and every other associated resource that iconv_open() allocated. like, all of it. the whole little resource bundle. gone. freed. released into the void 🫶

and if a file descriptor is used to implement the type iconv_t, then that file descriptor shall be closed too. yes, literally closed. no leftovers, no crumbs, no cap. 🔥

---

⭐ RETURN VALUE ⭐

if everything goes slay: 0 is returned. 💖

if it does NOT go slay: -1 is returned, and errno gets set to tell you what went wrong. 😭

---

👑 ERRORS 👑

iconv_close() may fail if:

• EBADF — the conversion descriptor is invalid. like bestie, that descriptor is not real. it's not valid. we can't work with that. 💀

also just so you know: the following sections are informative. so they're the "for your reading pleasure" part, not the "you must obey" part. 🌈
