fsm_getstate_str(9)

💅 fsm_getstate_str(9) — like, the Kernel API Manual, bestie 🎀

Okay so real talk, this is a page from the Kernel API Manual and it's about one tiny little function that's honestly kind of a vibe: fsm_getstate_str. It's the "what's my state called again?" girlie of the FSM world. Let's get into it ✨

---

🌸 NAME 🌸

fsm_getstate_str — retrieves the name of the current FSM state. That's it, that's the whole job, and she does it flawlessly. 👑

---

✨ SYNOPSIS ✨

const char * fsm_getstate_str (fsm_instance *fi );

Yep. One argument. One const char * coming back at you. Lowkey elegant, ngl. 🦋

---

🫶 ARGUMENTS 🫶

• fi — pointer to the FSM. That's your FSM instance bestie, literally just hand her over. 💖

---

⭐ RETURN ⭐

You get back the state name string 💫 — the name of the current state, as a string, ready to be printed or logged or whatever main character thing you're doing with it.

BUT — if the state is out of range, you don't get a name, you get the string "Invalid". No cap. That's the fallback and she said what she said. 😭

🌈 SEE ALSO 🌈

Okay that's the whole page bestie, mwah 💋 — this lil number lives over in ./drivers/s390/net and it's dated October 2026, so mark your calendar, and the manual name for the record is fsm_getstate_str(9). Slay, bye! 👋✨
