💅 rv_register_reactor(9) — from the Kernel API Manual, bestie 🎀

okay so like. picture this: it's giving kernel-internals era, and you've got a reactor that needs to be seen. this page is literally the glow-up ceremony for it ✨ (rv_register_reactor(9), if we're being formal — and we are, this is the Kernel API Manual, we have standards 🫶).

✨ NAME ✨

rv_register_reactor — register a rv reactor. that's it. that's the whole vibe. 🔥

---

🌸 SYNOPSIS 🌸

int rv_register_reactor (struct rv_reactor *reactor );

literally one function, one pointer, one int coming back atcha. clean. iconic. no notes. 👑

---

🦋 ARGUMENTS 🦋

• reactor — the rv_reactor to be registered. yes bestie, this is the one getting its moment. hand it over and let the kernel do its thing 💜

---

🎀 DESCRIPTION 🎀

Returns 0 if successful, error otherwise.

that's the whole story ngl — 0 means slay, anything else means something went sideways and you should probably look into it 😭. no cap, that's the entire contract.

• rv_unregister_reactor(9) — the breakup arc, for when the reactor's time is up 💀

iykyk, go read 'em all — the whole reactor friend group is tagged in this thing 🧚

fr fr: everything above is the source of truth, so don't go inventing extra behavior in your head. 0 = good, error = not good, and the reactor argument is the rv_reactor to be registered. periodt 💅
