PROBE::SOCKET.AIO_(3stap)

💖 PROBE::SOCKET.AIO_WRITE.RETURN 💖

okay bestie, gather round, because this is a page from the Socket Tapset section of the SystemTap Tapset Reference and it's literally about catching the exact moment a socket send wraps up. no cap, it's giving "I watched your message leave the building" energy. 🦋

✨ NAME ✨

probe::socket.aio_write.return — the conclusion of a message send via sock_aio_write, aka the moment your socket send says "and that's a wrap" 💅

---

🌸 SYNOPSIS 🌸

probe socket.aio_write.return {}

that's it. that's the whole vibe. a probe with zero arguments living its best main character life. 🎀

---

👑 VALUES 👑

every one of these is handed to you when the probe fires, so let's go through them like we're unpacking a haul:

• protocol — the protocol value. which protocol, you ask? the protocol value. she's mysterious like that. 🫶
• state — the socket state value, i.e. what headspace your socket is currently in.
• name — the name of this probe. iconic self-introduction moment.
• type — the socket type value. yes queen, know your type.
• family — the protocol family value. it's all about family. 🌈
• success — was the receive successful? 1 = yes, 0 = no. a simple girl. binary. we stan.
• flags — the socket flags value, the little accessories your socket is wearing.
• size — the size of the message received, in bytes. OR, plot twist, it's the error code if success = 0. 😭 so like, check success first or you'll be reading a number that means something completely different. iykyk.

🧚 CONTEXT 🧚

the message receiver. that's the context. that's who we are in this moment. 🍓

---

💜 DESCRIPTION 💜

this probe fires at the conclusion of sending a message on a socket via the sock_aio_write function. so like, not the beginning, not the middle — the very end, the closing credits, the final bow. if you wanna know how the send went down, this is where you pull up. 🔥
