💖 tipc_msg_build(9) 💖

okay so bestie, this page is from the Kernel API Manual, and it's all about tipc_msg_build — the function that creates a buffer chain containing the specified header and data. No cap.

✨ NAME ✨

tipc_msg_build — create buffer chain containing specified header and data.

🎀 SYNOPSIS 🎀

int tipc_msg_build (struct tipc_msg *mhdr , struct msghdr *m , int
       offset , int dsz , int pktmax , struct sk_buff_head *list );

🦋 ARGUMENTS 🦋

• mhdr — the message header, to be prepended to data 💅
• m — the user message 🫶
• offset — buffer offset for fragmented messages (FIXME) 😭 — yes, the original literally says FIXME, bestie.
• dsz — total length of user data 🔥
• pktmax — max packet size that can be used 👑
• list — buffer or chain of buffers to be returned to caller 🎀

🌸 DESCRIPTION 🌸

not me making a recursive call 😭 — but it's safe, bestie, because it can logically go only one further level down. periodt. ✨

⭐ RETURN ⭐

you get back the message data size or an errno: -ENOMEM, -EFAULT.
