allegro_404_char(3alleg4)

💖 allegro_404_char 💖

okay bestie, so this is a page from the Allegro manual — section 3alleg4, if you're keeping track — and it's all about one tiny lil global variable. her name is allegro_404_char and honestly? she's iconic.

✨ NAME ✨

allegro_404_char — the character Allegro pulls out when it literally cannot find a glyph. it's giving "substitute teacher energy" fr fr 🫶

🌸 SYNOPSIS 🌸

#include <allegro.h>

extern int allegro_404_char;

🎀 DESCRIPTION 🎀

so here's the tea ☕ — when Allegro goes looking for a glyph it needs inside a font and cannot find it, it does not just give up and cry (unlike me). nope. it just outputs whatever character is sitting in allegro_404_char instead. a little placeholder moment, we love a backup plan 💅

by default, that global is set to the caret symbol, '^'. but bestie, you are not stuck with the caret — it's a global, so you can swap it out for any other character you want. go off. make it yours. 🦋

example time:

/* Show unknown glyphs with an asterisk. */
allegro_404_char = '*';

look at her. one line. changing lives. 😭✨
