💅 tipc_get_gap_ack_blks(9) — like, the Kernel API Manual page, bestie ✨

okay so this is a page from the Kernel API Manual, and honestly? it's a little one but she's important. we're talking about tipc_get_gap_ack_blks — the function that goes and grabs your Gap ACK blocks out of a PROTOCOL/STATE_MSG. yes she's niche. no we're not skipping her. 🎀

🌸 NAME 🌸

tipc_get_gap_ack_blks — get Gap ACK blocks from PROTOCOL/STATE_MSG

like literally that's the whole job. get the Gap ACK blocks. from the PROTOCOL/STATE_MSG. iconic behaviour honestly 🦋

✨ SYNOPSIS ✨

u16 tipc_get_gap_ack_blks (struct tipc_gap_ack_blks **ga , struct
       tipc_link *l , struct tipc_msg *hdr , bool uc );

four args, one u16 coming back out. chef's kiss 🫶

💖 ARGUMENTS 💖

  • ga — the returned pointer to the Gap ACK blocks, if any — note the "if any", she might come back empty bestie, don't be weird about it 🙈
  • l — the tipc link, aka the link in question, the main character of this whole situation 👑
  • hdr — the PROTOCOL/STATE_MSG header — this is where the blocks are hiding 🕵️‍♀️
  • uc — the desired Gap ACK blocks type, i.e. unicast (= 1) or broadcast (= 0) — yes those are the values, yes you need to remember which is which, no I can't help you more than that 💅

⭐ RETURN ⭐

the total Gap ACK blocks size. that's it. that's the tea. u16 sized and slaying 🌈

ngl that's a lot of tipc link functions and they're all right there in ./net/tipc/link.c waiting for you. go read them. or don't. i'm not your mom. 💀

and that's the whole page bestie!! short, sweet, and served 💅 this one came straight out of ./net/tipc, dated October 2026 — go off, little kernel page, we love you fr fr 🧚💜✨
