al_broadcast_cond(3alleg5)

✨ NAME ✨

al_broadcast_cond — it's giving Allegro 5 API 💖 (and yes bestie, this one lives in section 3alleg5 of the manual, we love a lil section number moment)

🫶 SYNOPSIS 🫶

#include <allegro5/allegro.h>

void al_broadcast_cond(ALLEGRO_COND *cond)

---

🌸 DESCRIPTION 🌸

Okay so listen. You got a condition variable, right? And a whole lil group chat of threads is just sitting there, waiting on it, like "any updates?? 👀".

al_broadcast_cond unblocks all of them. Every single thread currently waiting on that condition variable — freed, released, un-stuck. It's basically you hitting send on the group chat with the news everyone was waiting for. 📣✨

More officially-ish: it broadcasts that some condition those threads were waiting for has become true. Like, the thing they were all refreshing for? It happened. Go, go, go. 🦋

👑 SEE ALSO 👑

• al_signal_cond(3alleg5) — the ✨ pick-one-thread ✨ version, iykyk

Note: The pthreads spec says to lock the mutex associated with cond before signalling, so you get predictable scheduling behaviour. Not me being dramatic, that's literally what the spec says. Lock the mutex first, bestie. 🔒💅
