al_set_errno(3alleg5)

💖 al_set_errno — Allegro 5 API 💖

okay bestie, welcome to al_set_errno from the Allegro 5 manual, page 3alleg5 ✨ she's a tiny one but she's iconic, no cap.

---

🌸 SYNOPSIS 🌸

void al_set_errno(int errnum)

---

🦋 DESCRIPTION 🦋

Set the error number for the calling thread. 💅

that's it, that's the whole vibe. al_set_errno takes your errnum and pins it onto the thread you're currently running on — so if you're juggling multiple threads, each one gets to keep its own little error number, fr fr. 🫶

note: it's per-thread, not global. your other threads are NOT getting the memo. 🙈
