relay_flush(9)

💅 relay_flush(9) — from the Kernel API Manual, bestie

okay so picture this: you're deep in relay land, right? that's the kernel's whole buffered-channel situation. and relay_flush is the little function that says "wrap it up, we're done here." that's literally the whole page. short, sweet, iconic. let's get into it 🎀

---

✨ SYNOPSIS ✨

void relay_flush (struct rchan *chan );

no return value, no drama. it just does the thing and dips. 💅

---

🌸 ARGUMENTS 🌸

• chan — the channel 💖 that's it, that's the argument. the channel you're flushing. she's the main character here.

---

🦋 DESCRIPTION 🦋

so what does it actually do? it flushes all the channel buffers — every single one, no cap — which basically means it forces a buffer switch. 🔥

think of it like hitting "send" on the group chat: everything sitting in the buffers gets pushed along and the channel moves on to the next one. periodt. ✨

ngl, that's the entire description. the manpage is not long. she said what she said and left. 😭
