💌 send_ext_msg_udp(9) — Kernel API Manual ✨

okay bestie, this is the send_ext_msg_udp(9) page and it's lowkey a whole delivery-service vibe. Let's get into it 🫶

---

🎀 NAME 🎀

send_ext_msg_udp — send extended log message to target 💅

---

✨ SYNOPSIS ✨

       void send_ext_msg_udp (struct netconsole_target *nt , struct
       nbcon_write_context *wctxt );

---

💅 ARGUMENTS 💅

• nt — the target that's getting the message 🎯 like, literally the destination bestie.
• wctxt — the nbcon write context, and it's carrying the message plus metadata 📦✨.

---

🔥 DESCRIPTION 🔥

okay so send_ext_msg_udp transfers an extended log message to nt — that's the main character move, periodt. 💫

but here's the chunking tea: if the message is longer than MAX_PRINT_CHUNK, it does not just dump it all at once. it gets split and transmitted in multiple chunks, and the ncfrag header field gets added to identify them 🧩📬. so yes, it's giving organized multi-chunk delivery, no cap.
