send_udp(9)

💌 send_udp(9) — like, the Kernel API Manual era ✨

Okay bestie, welcome to send_udp(9) — a whole little kernel API manual page from Kernel API Manual, and honestly? She's short, she's sweet, and she's doing exactly one job. Let's get into it 🎀

---

🦋 NAME 🦋

send_udp — a wrapper for netpoll_send_udp that also counts errors, because someone has to keep receipts 💅

---

✨ SYNOPSIS ✨

void send_udp (struct netconsole_target *nt , const char *msg , int len );

That's it. That's the whole signature. No cap 🫶

---

🍓 ARGUMENTS 🍓

• nt — the target you're sending the message to, bestie. This is who gets the vibes 📨
• msg — the actual message. The content. The main character 💖
• len — how long msg is. Gotta know the size, always 🎀

---

🌸 DESCRIPTION 🌸

So here's the tea, okay? send_udp calls netpoll_send_udp and then classifies the return value — like a vibe check on the result 😭

If an error happened, it increments the statistics in nt->stats accordingly. Errors get counted. She remembers everything. Iconic behavior tbh 👑

Heads up though: it only calls netpoll_send_udp if CONFIG_NETCONSOLE_DYNAMIC is disabled. So if that config is enabled? No call. That's just how it is, fr fr 🫶

🔥 SEE ALSO 🔥

• Kernel file ./drivers/net/netconsole.c
