✨ rfkill_is_epo_lock_active 💅

okay bestie, welcome to the rfkill_is_epo_lock_active(9) page — it's living in the Kernel API Manual and honestly she's a short one but she's iconic 🎀

---

🌸 NAME 🌸

rfkill_is_epo_lock_active — returns true EPO is active ✨

---

🦋 SYNOPSIS 🦋

bool rfkill_is_epo_lock_active (void );

---

🎀 ARGUMENTS 🎀

• void — no arguments, periodt 💅 she takes nothing, she needs nothing, she's low-maintenance like that

---

🔥 DESCRIPTION 🔥

So here's the vibe check, bestie 👑 this function returns 0 (false) if there is NOT an active EPO condition, and 1 (true) if there is an active EPO condition — and that active EPO condition locks all radios into one of the BLOCKED states 🚫📻 like, all of them, no cap.

And the flex? She can be called in atomic context 😭🔥 which is genuinely giving main character energy, ngl.
