ib_dispatch_event(9)

💅 ib_dispatch_event(9) — like, the kernel API manual bestie ✨

Okay so today we're learning about ib_dispatch_event, which lives in section 9 of the Kernel API Manual. Buckle up, it's literally a one-liner and yet somehow still iconic 🎀

---

🌸 NAME 🌸

ib_dispatch_event — dispatch an asynchronous event. That's it, that's the whole vibe check 💫

---

✨ SYNOPSIS ✨

void ib_dispatch_event (const struct ib_event *event );

Short, sweet, returns nothing, takes one thing. Main character energy fr fr 👑

---

🫶 ARGUMENTS 🫶

• event — the event you're dispatching. Yes bestie, that's the one. Hand it over 💖

---

🔥 DESCRIPTION 🔥

Okay so listen up, low-level driver besties, this part is for you:

When an asynchronous event happens, low-level drivers must call ib_dispatch_event to dispatch that event to all registered event handlers. All of them. Not some, not one, not "whoever's around" — all the registered event handlers get it. That's the whole job 🦋

Lowkey simple, highkey important — "must call" is not a suggestion, bestie 😭
