iscsi_data_xmit(9)

💅 iscsi_data_xmit — Kernel API Manual, bestie edition ✨

Okay so this is iscsi_data_xmit(9), from the Kernel API Manual, and honestly? It's a little baddie of a function with one job and a whole lot of friends (you'll see the SEE ALSO, it's giving reunion episode). Let's get into it 🫶

---

🌸 NAME 🌸

iscsi_data_xmit — literally just xmit any command into the scheduled connection 💫 no cap, that's the whole vibe

---

✨ SYNOPSIS ✨

int iscsi_data_xmit (struct iscsi_conn *conn );

---

🎀 ARGUMENTS 🎀

• conn — the iscsi connection 🦋 that's it, that's the one thing you pass in, and she is the main character here

---

👑 NOTES 👑

So here's the tea, bestie ☕ — this function can return -EAGAIN, and if it does, the caller must re-schedule it again later or recover. Like, you cannot just ignore her, okay? She's saying "not right now, try again" and you gotta respect it 😭

A '0' return code means the xmit was successful — slay, we love a clean zero 💖 periodt.
