PROBE::SOCKET.READ(3stap)

💖 probe::socket.readv.return — a Socket Tapset moment 💖

okay bestie, welcome to the PROBE::SOCKET.READ page from the Socket Tapset — yes that's the manual name, we're folding it in right here at the top like a lil name tag 🎀

---

✨ NAME ✨

probe::socket.readv.return — it's giving conclusion of receiving a message via sock_readv 🦋

---

✨ SYNOPSIS ✨

probe socket.readv.return {}

that's it. that's the whole vibe. no args, just vibes 🫶

---

✨ VALUES ✨

these are the lil goodies you get handed inside the probe, and ngl every single one of them is important:

• type — the socket type value 🔥
• name — the name of this probe, i.e. its whole identity, main character energy 👑
• protocol — the protocol value
• state — the socket state value
• flags — the socket flags value
• size — size of the message that got received, in bytes — OR the error code if success = 0 (so like, check success first bestie, don't be out here reading an error code as a byte count 😭)
• family — the protocol family value
• success — was the receive successful? 1 = yes, 0 = no. iconic binary behaviour 💅

---

✨ CONTEXT ✨

the message receiver. that's who's on stage here 💜

---

✨ DESCRIPTION ✨

so literally: this probe fires at the conclusion of receiving a message on a socket via the sock_readv function ✨ like it's the after-party of the readv, the credits rolling, the "we did it joe" moment 🎀
