PROBE::STAPIO.RECE(3stap)

💖 PROBE::STAPIO.RECEIVE_CONTROL_MESSAGE 💖

okay bestie so this one lives in the SystemTap Translator Tapset and it's the 3stap girlies' section, section 3, you know the vibe ✨

---

🌸 NAME 🌸

probe::stapio.receive_control_message — Received a control message 📨

---

🎀 SYNOPSIS 🎀

probe stapio.receive_control_message {}

literally that's it, that's the whole probe. no args, no drama, just vibes 💅

---

🦋 VALUES 🦋

okay so when this probe fires you get handed three lil cuties to play with:

• type — the type of message being send 👀 (yep, "send", we said what we said), and it's defined over in runtime/transport/transport_msgs.h 📂
• len — the length, in bytes, of the data blob 🧮
• data — a ptr to a binary blob of data that got sent as the control message 🫧

---

✨ DESCRIPTION ✨

This probe fires just after a message was received and before it gets processed 🎯

so like… it's the little moment in between?? the pause between the text arriving and you actually reading it?? iconic behavior honestly 😭 the message is there, the processing hasn't happened yet, and this probe gets the front-row seat 👑

ngl this is the spot if you wanna peek at a control message while it's still fresh and unprocessed 🍓
