llc_ui_send_data(9)

💅 llc_ui_send_data — the Kernel API Manual moment 🎀

okay so bestie, welcome to the llc_ui_send_data(9) page — yes it's a kernel API manual entry, yes it's about sending data over a reliable llc2 connection, and yes we're gonna get through it together ✨

---

🌸 NAME 🌸

llc_ui_send_data — send data via a reliable llc2 connection, fr fr 🦋

---

✨ SYNOPSIS ✨

int llc_ui_send_data (struct sock* sk , struct sk_buff *skb , int noblock );

---

🎀 ARGUMENTS 🎀

• sk — the connection that this socket is using 💫
• skb — the data the user wishes to send, like the actual goods 📦
• noblock — literally asking "can we block waiting for data?" like yes or no bestie, decide 😭

---

🫶 DESCRIPTION 🫶

So the whole vibe is: send data via a reliable llc2 connection. That's it, that's the job 💅

It returns 0 upon success, and non-zero if the action did not succeed — so 0 is the slay, anything else is the not-slay 🌈

⚠️ real talk: this function always consumes a reference to the skb. No cap. Every single time. So don't come for it later expecting that reference back, because it ate it 👑
