gui_strlen(3)

✨ gui_strlen ✨

okay bestie, welcome to the gui_strlen page from the Allegro manual 💖 it's a tiny lil function from the Allegro game programming library and honestly? she's short but she's mighty. let's get into it 🎀

🌸 NAME 🌸

gui_strlen — literally just returns the length of a string in pixels 🦋

and yeah, she's part of the Allegro game programming library, no cap 💅

🎀 SYNOPSIS 🎀

#include <allegro.h>

int gui_strlen(const char *s);

that's it. that's the whole vibe. one header, one function, one const char *s 🫶

💖 DESCRIPTION 💖

so gui_strlen is a helper function for use by the GUI routines ✨ she's the bestie that the GUI code calls when it needs to know stuff.

what she does: returns the length of a string in pixels 👑

⚠️ important detail, don't sleep on it: she measures in pixels, not characters. so it's giving actual on-screen width, not "how many letters are in there" 💀

and the lil plot twist 🌈 — she ignores & characters when she's measuring. like, those lil ampersands? not invited to the measurement party. they don't count toward the length, periodt.
