💖 tb_switch_configure(9) 💖

okay so real talk, bestie — this is a page straight out of the Kernel API Manual, section 9, and it's all about one little function that has main character energy in the Thunderbolt world. buckle up 🎀

---

✨ NAME ✨

tb_switch_configure — the one that uploads configuration to the switch, no cap 💅

---

🌸 SYNOPSIS 🌸

int tb_switch_configure (struct tb_switch *sw );

---

🦋 ARGUMENTS 🦋

• sw — the switch we're configuring. that's it, that's the whole vibe. the switch to configure 🫶

---

⭐ DESCRIPTION ⭐

so here's the tea: call this function before the switch is added to the system. it uploads configuration to the switch and makes it available for the connection manager to use. like, it hands the switch its whole setup and says "go, be iconic" ✨

and the best part? you can call it on the switch again after resume from low power states to re-initialize it. wake up bestie, we're going again 🌈

---

🔥 RETURN 🔥

• 0 on success — slay 💖
• a negative errno otherwise — not slay, go check your errno 😭
