es58x_calculate_crc(9)

🎀 NAME 🎀

okay bestie, welcome to es58x_calculate_crc(9) from the Kernel API Manual 💖. This one is literally just: es58x_calculate_crc — Compute the crc16 of a given URB. That's the whole vibe: you hand it a URB, it gives you a crc16. Slay. ✨

🦋 SYNOPSIS 🦋

u16 es58x_calculate_crc (const union es58x_urb_cmd *urb_cmd , u16
       urb_len );

💅 ARGUMENTS 💅

• urb_cmd — The URB command for which we want to calculate the CRC. That's the main character here 👑.
• urb_len — Length of urb_cmd. Must be at least bigger than 4 (ES58X_CRC_CALC_OFFSET + sizeof(crc)) — yes, that's the actual rule, so don't come in under that, bestie 🫶.

🌈 RETURN 🌈

crc16 value. That's it, that's the tea ☕✨.
