seq_get_buf(9)

🦋 seq_get_buf(9) 🦋

okay so bestie, we’re in the Kernel API Manual and this one is literally about getting a buffer so you can write arbitrary data to it. lowkey iconic kernel behavior ✨

---

🌸 NAME 🌸

seq_get_buf — get buffer to write arbitrary data to 💅

---

🎀 SYNOPSIS 🎀

size_t seq_get_buf (struct seq_file *m , char **bufp );

---

💖 ARGUMENTS 💖

• m — the seq_file handle. main character energy 🫶
• bufp — the beginning of the buffer is stored here. yes, that exact beginning ✨

---

🌈 DESCRIPTION 🌈

So seq_get_buf returns the number of bytes available in the buffer. that’s the useful number, bestie 💖

If there’s no space? it returns zero. not a single byte available, zero, that’s the vibe check result 😭

no space means zero. that’s it. no cap.
