get_page_state_name(9)

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

Okay so real talk: this is get_page_state_name(9), straight out of the Kernel API Manual. It's a tiny little function with one job and honestly? It eats. 💖

---

✨ NAME ✨

get_page_state_name — returns the name of a page state. That's it, that's the whole gig. 👑

---

🌸 SYNOPSIS 🌸

const char * get_page_state_name (enum vdo_page_buffer_state state );

---

🎀 ARGUMENTS 🎀

• state — the page state you want described. Hand it over and it'll tell you what it's called, no cap.

---

🦋 DESCRIPTION 🦋

So like, here's the vibe: if the page state is invalid, you don't get silence, you get a static string back — and lowkey the invalid state gets logged too. 📝 So it's not just gonna ghost you, it's gonna tell on you to the log. Periodt.

---

⭐ RETURN ⭐

A pointer to a static page state name. Note the word static — that's the whole personality of the return value, bestie. 💅
