STRUCT YNL_ERROR(9)

💅 struct ynl_error(9) — the Kernel API Manual, bestie edition 🎀

okay so picture this: it's a Kernel API Manual page, it's about struct ynl_error, and honestly? she's serving "tiny struct, big feelings." let's get into it ✨

---

🌸 NAME 🌸

struct ynl_error — the error you ran into while doing YNL stuff. yes, that error. 🫶

---

✨ SYNOPSIS ✨

like, here's literally the whole vibe:

struct ynl_error {
    enum ynl_error_code code;
    unsigned int attr_offs;
    char msg[512];
 };

three fields, no notes, periodt. 👑

---

🦋 Members 🦋

• code — your errno when it's a low value, or a YNL error code (that's the enum ynl_error_code, iykyk) 💀
• attr_offs — the offset of the bad attribute. this one is for the very advanced users only, like genuinely do not worry about her unless you know why you're here 🙈
• msg — the actual error message. the receipts. the "what happened" text 💌

---

💖 Description 💖

so this whole struct is just the error info for when YNL operations fail — that's the entire job, and she does it well. 🌈

⚠️ important bestie rule: users should interact with the err member of struct ynl_sock directly. do not go poking at this one on your own, fr fr.

the main exception to that rule? ynl_sock_create. that's the one place where you're allowed to color outside the lines. 🖍️✨

🔥 SEE ALSO 🔥

go read the kernel file ./tools/net/ynl/lib/ynl.h, and also these iconic little cross-references:

• struct ynl_family(9)
• struct ynl_sock(9)
• struct ynl_string(9)
• ynl_dump_empty(9)
• ynl_has_ntf(9)

that's the whole friend group, mwah 💋

and that's the page!! this came out of ./tools/net/ynl/lib — the source/version, October 2026 date and all — so big ups to the kernel, love that for us. bye bestie, go handle your errors responsibly 🧚💜
