💅 batadv_tt_tvlv_generate — the kernel API manual flex ✨

okay so bestie, welcome to the Kernel API Manual page for batadv_tt_tvlv_generate(9) — yes that's a whole mouthful, we're gonna get through it together 🫶

🌸 NAME 🌸

batadv_tt_tvlv_generate — fills the tvlv buffer with the tt entries from the specified tt hash 💖 (that's literally the whole vibe, no cap)

✨ SYNOPSIS ✨

u16 batadv_tt_tvlv_generate (struct batadv_priv *bat_priv , struct
batadv_hashtable *hash , void *tvlv_buff , u16 tt_len , bool
(*valid_cb)(const void *, const void *, u8 *flags) , void *cb_data );

🎀 ARGUMENTS 🎀

  • bat_priv — the bat priv holding all the mesh interface information, the whole group chat of the mesh basically 👑
  • hash — the hash table containing the tt entries, i.e. where all the lore lives
  • tvlv_buff — pointer to the buffer you're filling with the TT data, the little container you're packing 🎁
  • tt_len — the expected tvlv tt data buffer length, measured in number of bytes (bytes, bestie, not vibes)
  • valid_cb — function to filter tt change entries and to return TT flags; it's the bouncer at the door 🚪
  • cb_data — data passed to the filter function as argument, snacks for the bouncer fr fr

🦋 DESCRIPTION 🦋

Fills the tvlv buff with the tt entries from the specified hash 💫

and if valid_cb is not provided?? it literally becomes a no-op. nothing happens. it's giving main character who didn't show up 😭 so like, make sure you pass it.

🌈 RETURN 🌈

Remaining unused length in tvlv_buff — the leftover bytes, the crumbs at the bottom of the bag 🍓
