💖 PROBE::STAPRUN.SEN 💖

okay bestie, so this is a page from the SystemTap Translator Tapset manual, section 3stap — and it's literally about one specific probe point. it's giving very niche, very powerful, and we're gonna walk through it together 🫶

---

✨ NAME ✨

probe::staprun.send_control_message — sending a control message 💌

like, that's the whole vibe. this probe is your girl for watching a control message get yeeted out into the world.

---

🌸 SYNOPSIS 🌸

probe staprun.send_control_message {}

no arguments, no parameters, just vibes and curly braces. she's simple like that. 💅

---

🦋 VALUES 🦋

these are the read-only little treats you get to peek at when this probe fires, bestie:

• data — a ptr to a binary blob of data, and that blob is literally the control message being sent out. like, the actual payload. 🎀
• len — the length, in bytes, of that data blob. so you know exactly how much data you're looking at. 📏
• type — the type of the message being sent. and plot twist: it's defined over in runtime/transport/transport_msgs.h. so if you need to know which flavor of message this is, that's where you go. iykyk 🔥

---

🌈 DESCRIPTION 🌈

so when does this bad boy fire? at the beginning of the send_request function. that's it, that's the moment. the very start of it — like when the function walks in, flips her hair, and before she does anything else, this probe is already watching. 👑
