relay_buf_empty(9)

💅 relay_buf_empty(9) — a Kernel API Manual moment ✨

okay bestie, welcome to the Kernel API Manual, this is the page for relay_buf_empty(9) and it's honestly such a short little icon. like, blink and you'll miss her. but we're gonna give her the full main-character treatment anyway 🎀

---

✨ NAME ✨

relay_buf_empty — a boolean situation, lowkey: is the channel buffer empty or not? that's it, that's the whole vibe check 🦋

---

🫶 SYNOPSIS 🫶

int relay_buf_empty (struct rchan_buf *buf );

copy it exactly like that, spacing and all, no cap 💯

---

🌸 ARGUMENTS 🌸

• buf — the channel buffer in question. the one we're side-eyeing. the one we're asking "are you empty, queen?" 👑

---

💖 DESCRIPTION 💖

so here's the tea, and it's genuinely this simple: it returns 1 if the buffer is empty, and 0 otherwise. that's the whole function. not me getting emotional over a return value 😭

so like — 1 = empty, 0 = not empty. she's a boolean at heart, fr fr. tiny function, enormous slay ✨
