igc_up(9)

💅 igc_up(9)

ok so this is a page from the Kernel API Manual, section 9, and it's about one little function that does a very big job. Strap in bestie 🎀

---

✨ NAME ✨

igc_up — opens the interface and gets it ready to handle traffic 🚦

Like, it literally wakes the NIC up and says "ok girl, go be a network card." Obsessed.

---

🌸 SYNOPSIS 🌸

void igc_up (struct igc_adapter *adapter );

that's it. that's the whole signature. no return value, no drama, no cap. 💅

---

🦋 ARGUMENTS 🦋

• adapter — the board private structure 🫶 this is the igc adapter's own little private stash of state, and you hand it over so the function has something to work with. main character energy fr.

🔥 SEE ALSO 🔥

ok so this is the part where the manpage lists, like, everyone igc has ever met. it's giving group chat with 85 members where everybody knows each other. 💀
