wol_calc_crc(9)

wol_calc_crc(9) 💖

omg hi bestie 🫶 welcome to the Kernel API Manual page for wol_calc_crc(9) — yes, the manual name is folded right in near the top because we're cute like that. This is the WOL CRC situation and it's lowkey iconic. No cap.

🌸 NAME 🌸

wol_calc_crc — WOL CRC. That's the whole name. Short, sweet, and fully the vibe. 💅

✨ SYNOPSIS ✨

Here's the exact signature, copy-paste energy, no edits:

u16 wol_calc_crc (int size , u8 *pattern , u8 *mask_pattern );

🎀 ARGUMENTS 🎀

okay so the args are giving tiny but important:

• size — size of the wake mask. Like literally the size of the wake mask, bestie.
• pattern — data pattern. The data pattern in question.
• mask_pattern — mask. Yep, the mask. 🎀

💅 DESCRIPTION 💅

Compute the wake on lan crc hashes for the packet header we are interested in. That's the whole main character moment: it computes those WOL CRC hashes for the packet header you're interested in. No extra lore, no side quests, periodt. ✨
