✨ NAME ✨

al_ustr_vappendf — Allegro 5 API 🎀

---

🌸 SYNOPSIS 🌸

#include <allegro5/allegro.h>

bool al_ustr_vappendf(ALLEGRO_USTR *us, const char *fmt, va_list ap)

---

💅 DESCRIPTION 💅

So it’s literally like al_ustr_appendf(3), except instead of passing the arguments themselves, you pass the variable argument list directly. The va_list is the main character here, no cap 👑.

Also lowkey important: peep al_ustr_newf(3) for the details about the %s and %c specifiers 🦋.

It returns true on success, and false on error. periodt 💅
