seq_buf_pop(9)

💅 seq_buf_pop — like, the Kernel API Manual page you actually wanna read ✨

okay bestie, welcome to the Kernel API Manual entry for seq_buf_pop, and trust me, this one is short, sweet, and honestly kind of iconic 🎀

✨ NAME ✨

seq_buf_pop — pop off the last written character 🍓

---

🌸 SYNOPSIS 🌸

int seq_buf_pop (struct seq_buf *s );

---

🦋 ARGUMENTS 🦋

• s — the seq_buf handle 💖 like, the actual buffer you're messing with, no cap

---

👑 DESCRIPTION 👑

Removes the last written character from the seq_buf s. that's it. that's the whole job. she takes the last character you wrote and she pops it right off 💅

and then — Returns the last character or -1 if it is empty 😭 so yeah, if your buffer's got nothing in it, you get -1 back, which is lowkey the saddest little return value ever ngl

fr fr: empty buffer → -1. not empty → you get the character that got popped. no guessing, that's literally what the manpage says 🫶
