al_ustr_insert(3alleg5)

💖 al_ustr_insert — Allegro 5 API 💖

okay bestie, welcome to the al_ustr_insert(3alleg5) page, straight out of the Allegro reference manual ✨ this one is short and sweet and honestly iconic.

🌸 SYNOPSIS 🌸

#include <allegro5/allegro.h>

bool al_ustr_insert(ALLEGRO_USTR *us1, int pos, const ALLEGRO_USTR *us2)

---

🦋 DESCRIPTION 🦋

so here's the vibe: this function inserts us2 into us1, and it starts doing that at the byte offset pos. that's it, that's the whole job 💅

okay but here's the tea about pos, bestie, listen up:

• pos cannot be less than 0. like, that's just not a thing. no cap.
• if pos is past the end of us1? then the gap between the end of the string and pos gets padded with NUL ('\0') bytes. yep, it just fills that space with NULs. it's giving "making room" energy. 🫶

if you need it, go use al_ustr_offset(3alleg5) to find the byte offset for a given code point index — that's literally what it's for, iykyk. 🧚

and the return value? it returns true on success and false on error. that's the whole vibe check. ✅

lowkey important: pos has to be 0 or more, and if you go past the end you're getting NUL padding whether you asked for it or not. 🌈
