ntmp_ett_update_entry(9)

📦 version 7.3.1, in nixpkgs unstable

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

okay so this is a page from the Kernel API Manual (section 9, the big-leagues kernel dev section, iykyk) and it's about one very specific little function called ntmp_ett_update_entry. it's giving "glow-up for a table entry" energy ✨

🌸 NAME 🌸

ntmp_ett_update_entry — updates the configuration element data of the entry you point at. literally: you pick the entry, it gets the new cfge data. no cap 🫶

✨ SYNOPSIS ✨

int ntmp_ett_update_entry (struct ntmp_user *user , u32 entry_id , const
struct ett_cfge_data *cfge );

three args, one int coming back at you. simple. iconic. 💅

🦋 ARGUMENTS 🦋

  • user — the target struct ntmp_user 🫶 this is the one you're working on
  • entry_id — the entry ID, aka which entry we're updating (u32, bestie, not a guess)
  • cfge — the configuration element data (const struct ett_cfge_data *) — this is the new glow-up getting applied

👑 RETURN 👑

0 on success. anything else? negative error code, so keep an eye out 💀

fr fr, check that return value. 0 = slay, negative = go read the errors.

🎀 SEE ALSO 🎀

the kernel file lives at ./drivers/net/ethernet/freescale/enetc/ntmp.c — that's the main character's home address 🏠

and here's the whole friend group, all of them, in the order the page gives them:

add / update / delete / set / search, the whole roster 😭 they really did that

🌈 tiny reminder: nothing here is "figure it out yourself" territory — the args, the return, and that exact file path are all straight from the page. if you change the vibe you do not get to change the facts, periodt.

✨ mwah, that's the page ✨ brought to you by the source path ./drivers/net/ethernet/freesca... (she got cut off mid-path, tragic 🙈) and dated October 2026, closing out with the one and only ntmp_ett_update_entry(9) 🧚‍♀️💜 stay slay, bestie, and may your return values always be 0 🌸
