💅 hsi_claim_port — the kernel API manual, bestie edition ✨

okay so real talk, this is hsi_claim_port(9) from the Kernel API Manual and it's honestly icon behavior for such a tiny page 🎀

🌸 NAME 🌸

hsi_claim_port — claim the HSI client's port, like putting your name on the aux cord but for hardware 🎧

---

✨ SYNOPSIS ✨

int hsi_claim_port (struct hsi_client *cl , unsigned int share );

yep that's the whole vibe. two args, one int back. no cap. 💅

---

🦋 ARGUMENTS 🦋

• cl — the HSI client that wants to claim its port 🫶 literally the main character of this call.
• share — flag that says whether the client wants to share the port or not 🤝 so like... are we splitting custody or is this a solo era?

---

💖 DESCRIPTION 💖

Returns -errno on failure, 0 on success. that's it, that's the whole paragraph, and honestly? she keeps it short and slays 😭 no filler, no fluff, just return values periodt.

ngl, if you get -errno back you're in your flop era — check what went wrong. if you get 0, congratulations bestie, you ate 🔥
