parity8(9)

🎀 NAME 🎀

parity8 — get the parity of an u8 value. This is the parity8(9) page from the Kernel API Manual, hiii bestie 💖

✨ SYNOPSIS ✨

int parity8 (u8 val );

🦋 ARGUMENTS 🦋

• val — the value to be examined 👀

🌸 DESCRIPTION 🌸

Okay so parity8() determines the parity of the u8 argument. That's the whole vibe: it tells you the parity of that value ✨

💫 RETURN 💫

• 0 for even parity
• 1 for odd parity

🔥 NOTE 🔥

This function informs you about the current parity. Example to bail out when parity is odd:

if (parity8(val) == 1) return -EBADMSG;

If you need to calculate a parity bit, you need to draw the conclusion from this result yourself. Example to enforce odd parity, parity bit is bit 7:

if (parity8(val) == 0) val ^= BIT(7);
