PROBE::SOCKET.WRIT(3stap)

✨ PROBE::SOCKET.WRIT ✨

okay bestie, welcome to section 3stap of the manuals — this one's the SystemTap Tapset Reference page for a probe, and it's short but it's mighty. let's get into it 💅

---

🦋 NAME 🦋

probe::socket.writev — the probe that catches a message getting sent via socket_writev

---

🌸 SYNOPSIS 🌸

probe socket.writev {}

---

🎀 VALUES 🎀

every one of these is a lil variable you get to peek at. collect them all like they're stickers:

• type — the socket type value 🫶
• name — the name of this probe (yes, the probe knows its own name, main character behavior honestly)
• state — the socket state value
• protocol — the protocol value
• flags — the socket flags value
• size — the message size, in bytes 📏
• family — the protocol family value

---

🧚 CONTEXT 🧚

who's in this scene? the message sender. that's it, that's the context 💖

---

🔥 DESCRIPTION 🔥

so here's the tea: this probe fires at the beginning of sending a message on a socket via the sock_writev function. beginning of the send, before the message has gone anywhere — you're catching it right at the jump, no cap ✨
