tb_sw_set_unplugged(9)

💅 tb_sw_set_unplugged(9) — like, the whole vibe ✨

okay so bestie, welcome to the Kernel API Manual, section 9. This is the page for tb_sw_set_unplugged and honestly it's a short one, but that doesn't mean we're skipping anything. 🎀

---

🌸 NAME 🌸

tb_sw_set_unplugged — sets is_unplugged on the switch and on all the downstream switches too 🫶

like, it's a chain reaction situation. one switch gets marked, the whole downstream fam gets marked. iconic.

---

✨ SYNOPSIS ✨

void tb_sw_set_unplugged (struct tb_switch *sw );

yep. that's the whole signature. void return, one argument, no notes. she's simple, she's efficient, she's that girl 💅

---

🦋 ARGUMENTS 🦋

• sw — the Router (a struct tb_switch *) that you're marking as unplugged. that's it. that's the argument. give her a switch and she'll flag it 🔥

so like, this is a one-argument function and the description of that argument is literally "Router to mark unplugged". the manpage is not beating the minimalist allegations today ngl 😭 but we respect it.

🫶 reminder bestie: when a manpage says SEE ALSO, that's your "go read these next" list. every single one of those (9) pages is a real cross-reference, so if you're deep in Thunderbolt driver land, you now have a whole reading list. slay.

🎀 the cute little sign-off 🎀

this page comes to you from ./drivers/thunderbolt (yep, that's the source/version bit, mwah) and it was dated October 2026 in the footer. so like, future-dated aesthetics, we love that for her. periodt. 💖🌈⭐

stay unplugged-ish (but like, only the is_unplugged flag, not your actual hardware, bestie 😭🔥) — mwah 💋
