💖 batadv_tp_wait_available(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ — this one's a little function from the batman-adv kernel world and honestly? it's giving "patient bestie waiting for her turn at the mirror" 🪞💅

🌸 NAME 🌸

batadv_tp_wait_available — literally just wait until the congestion window becomes free or the timeout is reached, no cap 💀

🦋 SYNOPSIS 🦋

int batadv_tp_wait_available (struct batadv_tp_sender *tp_vars , size_t
plen );

🎀 ARGUMENTS 🎀

  • tp_vars — the private data of the current TP meter session 🫶 like, the little personal stash of info for the session you're working with rn
  • plen — size of the payload of a single message 📨 (yes it's a size_t, yes it matters)

⭐ RETURN ⭐

okay so the return values here are kind of a vibe check on how the wait ended, so pay attention bestie 👀

  • 0 — the condition evaluated to false after the timeout elapsed 😔 (time ran out, still not free)
  • 1 — the condition evaluated to true after the timeout elapsed ✅ (time ran out, but it did become free)
  • the remaining jiffies (at least 1) — the condition evaluated to true before the timeout elapsed 🔥 (iconic, early win, main character energy)
  • -ERESTARTSYS — it was interrupted by a signal 😭 rude, honestly
