STRUCT RFKILL_EVENT_EXT(9)

✨ NAME ✨

okay so this is the <pink>Kernel API Manual</pink> page for struct rfkill_event_ext — the struct that handles events for userspace on /dev/rfkill 💖

🎀 SYNOPSIS 🎀

struct rfkill_event_ext {
    __u32 idx;
    __u8 type;
    __u8 op;
    __u8 soft;
    __u8 hard;
    __u8 hard_block_reasons;
 };

that's the whole shape of it, bestie 🫶

💅 MEMBERS 💅

• idx — the index of the dev rfkill. like, which one it is ✨
• type — the type of the rfkill struct 🌸
• op — the operation code 💫
• soft — the soft state, and it's 0/1 only, no in-between 🎀
• hard — the hard state, also strictly 0/1 ⭐
• hard_block_reasons — this one only counts (valid) if hard is set, iykyk. it's one or several reasons, pulled from enum rfkill_hard_block_reasons 🔥

🌈 DESCRIPTION 🌈

so this structure? it's the one used for userspace communication on /dev/rfkill 💖 and it works both directions — it carries events from the kernel, and it carries control to the kernel. main character energy, honestly 👑

also: see the extensibility docs below 👇 (yes, for real, they're in the SEE ALSO, go look)

okay that's the whole page, no cap 🧚 this came to you straight from ./include/uapi/linux, dated October 2026 — and it's literally titled struct rfkill_event_ext(9), in case you forgot already 😭 go touch /dev/rfkill responsibly, love u, bye 💜
