rtrs_clt_change_state(9)

✨ rtrs_clt_change_state(9) ✨

okay so this is a page straight out of the Kernel API Manual and it's literally about flipping a session's state through the session state machine 🦋. it's giving tiny function, big responsibility, and honestly? we love her for it 💅

---

🌸 SYNOPSIS 🌸

bool rtrs_clt_change_state (struct rtrs_clt_path *clt_path , enum
       rtrs_clt_state new_state );

that's it, that's the whole vibe 🎀

---

💖 ARGUMENTS 💖

• clt_path — the client path you're changing the state of. like, this is the thing getting its glow-up 🔥
• new_state — the state you're changing it to. the destination. the final form. the main character energy ✨

---

🫶 DESCRIPTION 🫶

so bestie, here's what happens: it returns true if the session's state actually gets changed to the new state, otherwise it returns false 😭 (yes, that's the whole description, no cap).

Locks: the state_wq lock must be held 🔒 — like, do NOT come in here unlocked, that's not the move, fr fr 💀
