🦋 ARGUMENTS 🦋

• type — the type of event you're looking for, like literally the whole vibe check of what you want back 🔍

⭐ DESCRIPTION ⭐

So here's the tea: it returns an event of type type — and if there's nothing matching, you get NULL instead. no cap, that's it 😭

⚠️ big one: this is called with trace_event_read_lock held. so like, the lock is already on when you roll up. don't be the main character who forgets that, fr fr 🔥
