n_hdlc_buf_put(9)

💅 n_hdlc_buf_put — kernel API manual, but make it make sense ✨

okay so bestie, welcome to the n_hdlc_buf_put(9) page 💖 this is one of those little kernel helper functions from the n_hdlc fam, and honestly? it's giving "small but mighty" 🦋 the way this whole page lives in section 9 (kernel API manual) and it's literally just one job — but we're gonna do it right, no cap.

🌸 NAME 🌸

n_hdlc_buf_put — add the specified HDLC buffer to the tail of the specified list 🎀

like, that's it. that's the whole vibe. you got a buffer, you got a list, and the buffer goes to the end of that list. tail-end behaviour, main character energy 🔥

---

✨ SYNOPSIS ✨

void n_hdlc_buf_put (struct n_hdlc_buf_list *buf_list , struct
       n_hdlc_buf *buf );

it's a void function, so it doesn't hand you anything back — it just does the thing and dips 🙈 no return value to obsess over, bestie.

---

🩷 ARGUMENTS 🩷

• buf_list — pointer to the buffer list 💅 this is the list you're appending to. the destination. the moment.
• buf — pointer to the buffer 🎀 this is the actual buffer getting tacked onto the tail of that list. the little guy being added. the icon.

both of them are pointers, both of them matter, and yeah — miss either one and nothing about this works, iykyk 💀

ngl, this page is short — but that's not a red flag, it's just a very focused queen doing one job 💅

aaand that's the page, bestie 🫶 this was section 9 of the kernel API manual, living under ./drivers/tty, dated October 2026 😭 — go drink some water and go read the rest of the n_hdlc docs, ily, periodt 🍓💜
