ssh_crc(9)

💅 ssh_crc(9) — the Kernel API Manual glow-up 🎀

okay so bestie, welcome to ssh_crc(9) from the Kernel API Manual — yes that's the manual name, we're not copying the header line, iykyk ✨

---

🌸 NAME 🌸

ssh_crc — literally just computes the CRC for SSH messages, no cap 💫

---

✨ SYNOPSIS ✨

u16 ssh_crc (const u8 *buf , size_t len );

like... two args, one lil return value, she's lowkey iconic 🫶

---

🦋 ARGUMENTS 🦋

• buf — the pointer that points at the data whose CRC you want computed. she's giving "here's my data, do ur thing" 💁‍♀️
• len — the length of that data, i.e. how much of it we're CRC-ing. length matters, periodt 📏

---

👑 RETURN 👑

returns the CRC computed on the data you handed over — specifically the kind used for SSH messages. that's it, that's the whole vibe check 🔥
