batadv_mcas..._shrink_fill(9)

📦 version 7.3.1, in nixpkgs unstable

💅 batadv_mcast_forw_shrink_fill(9) — like, welcome to the Kernel API Manual bestie

okay so picture this: you're deep in the Kernel API Manual, section 9, and you've found batadv_mcast_forw_shrink_fill 🎀. That's the whole title, we're not abbreviating, the truncation in the header is just the terminal being dramatic. Strap in, this one's a little swap-and-fill situation and honestly it's giving "tiny function, big responsibility" 👑

✨ SYNOPSIS ✨

bool batadv_mcast_forw_shrink_fill (u8 *slot , u16 num_dests_slot );

that's it. that's the whole signature. no cap, she's compact 🫶

🌸 ARGUMENTS 🌸

  • slot — the zero-MAC destination entry in a tracker TVLV that we're trying to fill, like it's an empty seat at the function and we're the friend who's scouting the room for someone to sit in it 💺
  • num_dests_slot — how many entries are left in the tracker TVLV from the slot and including the slot itself. yes, inclusive. yes, that matters. count it right or don't count at all 🙈

🦋 DESCRIPTION 🦋

so what she actually does: she goes hunting 🔍. Starting after the slot pointer you handed her, she searches the tracker TVLV for the next destination entry that does not have a zero MAC.

and if she finds one? she swaps it. 🔁 She takes that non-zero destination entry and trades places with the zero-MAC destination entry that slot is pointing at. The empty seat gets filled, the good entry moves up, everybody claps 👏✨

if she doesn't find one — nothing happens, no swap, no drama, we just move on 💀

🥺 RETURN 🥺

  • true — the slot got swapped/filled successfully, slay 💖
  • false — it didn't, and that's okay, we're still proud of her
