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

okay bestie, welcome to the Allegro manual (section 3alleg4, iykyk) 🌸 this one's about a tiny little function with main character energy: pack_ungetc from the Allegro game programming library. she's small. she's powerful. she puts a character BACK. periodt. 💅

✨ NAME ✨

pack_ungetc</purpose> — moves one single character back to the input buffer. this is your Allegro game programming library girlie 🎀

🦋 SYNOPSIS 🦋

#include <allegro.h>

int pack_ungetc(int c, PACKFILE *f);

like. that's it. that's the whole vibe. no cap. ✨

🌸 DESCRIPTION 🌸

so here's the tea, bestie 🍓 — this function puts a character back into the file's input buffer. it's giving "jk, never mind, put it back" energy and honestly? iconic.

but listen — just like ungetc from libc, only a single push back is guaranteed. one. uno. a single. don't get greedy, she said what she said 💀

⚠️ note, and this one MATTERS: pack_fgets <highkey>internally uses</highkey> pack_ungetc, so never use pack_ungetc directly after using pack_fgets on a PACKFILE. like, just don't. that's the rule. respect it or things get weird 😭

👑 RETURN VALUE 👑

  • returns c on success 🫶 slay
  • or EOF on error 💀 rip
