netlbl_unlhsh_add_iface(9)

📦 version 7.3.1, in nixpkgs unstable

💖 netlbl_unlhsh_add_iface — like, the whole kernel API manual page, bestie 💖

okay so this is netlbl_unlhsh_add_iface(9) from the Kernel API Manual, and honestly? she's a little baby function with one job and she does it. no notes. 🎀

✨ NAME ✨

netlbl_unlhsh_add_iface — adds a brand new interface entry to the hash table. that's it, that's the whole vibe. 💅

🦋 SYNOPSIS 🦋

struct netlbl_unlhsh_iface * netlbl_unlhsh_add_iface (int ifindex );

like literally that's the whole signature, copy it exactly, no cap. ⭐

🌸 ARGUMENTS 🌸

  • ifindex — the network interface. yes bestie, the interface. that's the one. 🫶

👑 DESCRIPTION 👑

okay so here's the tea: this function adds a new, empty, interface entry into the unlabeled connection hash table. 🎀

on success you get a pointer back to that new interface entry — slay. 🔥

on failure? you get NULL. and not in a cute way. it's giving "nothing for you." 💀

no cap, that's the entire contract: success → pointer, failure → NULL. don't overthink her, she's an icon already.

🌈 SEE ALSO 🌈

the kernel file, first of all, because we stan source:

  • ./net/netlabel/netlabel_unlabeled.c

and then the whole friend group, fr fr — every single one, in order, because nobody gets left out of the group chat: 🧚

like, look at that list. twenty-six besties. main character energy across the entire unlabeled subsystem. 👑

and that's the page!! mwah 💜 this little angel lives in ./net/netlabel and the docs are dated October 2026 — screenshot it, cite it, love her. bye bestie!! 🍓✨
