ad_marker_send(9)

👑 ad_marker_send — like, the whole page, bestie 💅

Okay so this is a page from the Kernel API Manual, and we're talking about ad_marker_send(9). Buckle up, it's a short one but it's iconic. ✨

---

🌸 NAME 🌸

ad_marker_send — bestie, this is the one that sends marker information/response on a given port. That's it, that's the vibe. 🎀

---

🦋 SYNOPSIS 🦋

int ad_marker_send (struct port *port , struct bond_marker *marker );

No cap, that's the whole signature. She takes two pointers and returns an int. Simple. Elegant. Main character energy. 👑

---

💖 ARGUMENTS 💖

• port — the port we're looking at. Like, literally the actual port we're clocking rn. 👀
• marker — the marker data to send. This is the payload, the moment, the whole reason we're here. 🫶

---

⭐ RETURN ⭐

• 0 on success 🎉
• < 0 on error 😭

That's the entire contract. Zero means slay, anything negative means it's giving "something went wrong" — periodt.
