💖 pack_fclose — the manual page, but make it cute 💖

okay so bestie, we're in the Allegro manual, section 3alleg4, and today's main character is pack_fclose. yes she's a little function, yes she's iconic, and yes she deserves your full attention. sit down, grab a boba, let's go 🧋✨

✨ NAME ✨

pack_fclose — closes a stream that was previously opened. Allegro game programming library. that's it. that's the whole vibe. she opens nothing, she starts nothing, she simply ends things, gracefully, like a queen exiting a group chat 💅

🌸 SYNOPSIS 🌸

#include <allegro.h>

int pack_fclose(PACKFILE *f);

look at her. one parameter. one return. no drama. we love a low-maintenance icon 🫶

🦋 DESCRIPTION 🦋

so what she does is: she closes the stream f that you previously opened with pack_fopen() or pack_fopen_vtable(). that's her whole job and she does it flawlessly, no cap ✨

⚠️ okay but listen, this part is important bestie: once you've closed the stream, doing anything to it afterwards will yield errors in your application — like, it could literally crash it — or it could even block your OS. not me being dramatic, that's fr fr in the docs. so like… don't touch it after she's gone. it's giving haunted house. it's giving do-not-perceive-me. 💀🙈

🎀 RETURN VALUE 🎀

she returns zero on success. that's the happy path, that's the slay, that's the green flag 💚

on error, she returns an error code, and that same error code is also stored in errno. so if you're nosy (you are, and valid), go check errno 👀

and here's the tea: this function can only fail when writing to files. if the file was opened in read mode, she will always succeed. always. no exceptions. periodt. 👑
