PROBE::SOCKET.SEND(3stap)

💖 PROBE::SOCKET.SEND — socket tapset, bestie edition 💖

okay so this is a page from the SystemTap Tapset Reference (section 3stap), and it's literally all about the socket.sendmsg probe. sit with me, we're gonna slay this 🫶

---

✨ NAME ✨

probe::socket.sendmsg — a message is currently being sent on a socket. that's the whole vibe. 💌

---

🎀 SYNOPSIS 🎀

probe socket.sendmsg {}

yes bestie, that's it, that's the whole thing. no args, no fuss, just a probe hanging out waiting for a message to go out. 💅

---

🌸 VALUES 🌸

these are the local variables you get to play with inside the probe, and ngl they're kind of iconic:

• protocol — the protocol value. what kind of protocol are we talking here, bestie 👀
• state — the socket state value. the mood of the socket, fr fr.
• type — the socket type value.
• name — the name of this probe. hi, it's me 🙈
• flags — the socket flags value.
• size — the message size in bytes. how chunky is the message, exactly 📏
• family — the protocol family value.

---

🦋 CONTEXT 🦋

the context is: the message sender. the one doing the sending. the main character of this moment, honestly 👑

---

🔥 DESCRIPTION 🔥

so this probe fires at the beginning of sending a message on a socket, and it does that via the sock_sendmsg function. that's the whole story — beginning of the send, right there. no cap. ✨
