tb_domain_event(9)

💅 tb_domain_event(9) 💅

okay so bestie, welcome to the Kernel API Manual — this one's tb_domain_event, and it's genuinely such a little icon. small function, big job: it's the one that tells userspace "hey girl, something happened" 🎀

---

✨ NAME ✨

tb_domain_event — Notify userspace about an event in domain

like literally, that's the whole assignment. notifying. serving cunt. keeping userspace in the loop 🫶

---

🌸 SYNOPSIS 🌸

void tb_domain_event (struct tb *tb , char *envp[] );

no cap, that's the entire signature. she takes two things and returns void, because she's not here for your return values, she's here to communicate 💅

---

🦋 ARGUMENTS 🦋

• tb — Domain where event occurred. this is the domain, the moment, the main character of the whole situation 👑
• envp — Array of uevent environment strings (can be NULL). yeah bestie, NULL is allowed here, she's flexible like that 🙈

---

⭐ DESCRIPTION ⭐

okay so real talk: this function provides a way to notify userspace about any events that take place in the domain. any events. all the events. she does not gatekeep, she does not play favourites, she simply delivers the news 📣✨

think of her as the group chat announcement for kernel-land: something happens in the domain, and tb_domain_event is the one sliding into userspace's DMs to be like "bestie, heads up" 😭

it's giving messenger energy. it's giving "I'm just the middleman and I'm thriving." periodt 💖
