ustrcat(3alleg4)

💖 ustrcat — Allegro manual, bestie edition 💖

okay so you're in the Allegro game programming library section of the manual and you clicked on ustrcat(3alleg4). iconic of you. let's get into it 🎀

✨ SYNOPSIS ✨

#include <allegro.h>

char *ustrcat(char *dest, const char *src);

that's the whole vibe, no cap.

🌸 DESCRIPTION 🌸

so basically this function concatenates src to the end of dest. that's it. that's the function. short king behavior fr fr.

but bestie. listen. you should try to avoid this function because it is very easy to overflow the destination buffer. like, genuinely. it's giving danger. it's giving "why is my game crashing and also why is my neighbor's wifi password in my save file." use ustrzcat instead, that one actually checks stuff. periodt. 💅

not me being dramatic about it, the manpage literally says to avoid it. i'm just saying it louder. 🫶

👑 RETURN VALUE 👑

it returns the value of dest. so if you did char *result = ustrcat(dest, src); then result and dest are literally the same pointer. main character energy, no originality, but okay. ✨
