crc_itu_t(9)

💅 crc_itu_t(9)

okay so bestie, welcome to the Kernel API Manual entry for crc_itu_t — yes that's the manual name, yes it's giving official, and yes we're about to make CRC math feel like a group chat 💖

---

✨ NAME ✨

crc_itu_t — compute the CRC-ITU-T for the data buffer 🌸

Like, it crunches your buffer and hands you back a CRC-ITU-T value. That's the whole vibe. No cap.

---

✨ SYNOPSIS ✨

u16 crc_itu_t (u16 crc , const u8 *buffer , size_t len );

literally that's it, that's the signature, look at her go 👑

---

✨ ARGUMENTS ✨

• crc — the previous CRC value 🫶 yes, the one you already had. You're updating it, not starting from zero (unless you are, iykyk).
• buffer — data pointer 💫 it points at your data. Your data. Right there.
• len — number of bytes in the buffer 🎀 exactly how many bytes, no guessing, we respect the count in this house.

---

✨ DESCRIPTION ✨

Returns the updated CRC value ✨ that's the tea. You give it the previous CRC plus the buffer plus the length, and it gives you back the updated CRC value. Simple, iconic, does exactly what it says on the tin 💅
