seq_buf_can_fit(9)

💅 seq_buf_can_fit(9) — the Kernel API Manual, bestie edition 🎀

okay so picture this: you're deep in the kernel, you've got a seq_buf, and you're about to shove more data in there. but like… will it even fit?? that's the whole entire vibe of seq_buf_can_fit(9), and honestly it's giving main character energy. this page is from the Kernel API Manual (yes, the seq_buf_can_fit(9) one, scroll no further 💖).

✨ NAME ✨

seq_buf_can_fit — can the new data fit in the current buffer? 🫶

lowkey the most useful question you can ask before you commit. no cap.

---

🦋 SYNOPSIS 🦋

bool seq_buf_can_fit (struct seq_buf *s , size_t len );

that's it. that's the whole call. returns a bool, takes the descriptor and a length. iconic, honestly.

---

🌸 ARGUMENTS 🌸

• s — the seq_buf descriptor 💌 like, the buffer situation itself. you know her.
• len — The length to see if it can fit in the current buffer 📏 that's the amount of new data you're hoping to squeeze in there.

---

⭐ RETURN ⭐

true if there's enough unused space in the seq_buf buffer to fit the amount of new data according to len. 💀 and if it's false… bestie, it does not fit. do not pass go. do not write past the end. we don't do that here 🙈

ngl, checking first is the entire move. seq_buf_can_fit is your vibe check before the write. 🧚💜
