w1_triplet(9)

🎀 w1_triplet 🎀

Okay so this is w1_triplet(9), straight out of the Kernel API Manual, and it’s giving lowkey kernel triplet-search energy ✨. Bestie, the manpage says it does a triplet and that’s used for searching ROM addresses — iconic, honestly 💖.

✨ NAME ✨

• w1_triplet — * Does a triplet - used for searching ROM addresses.

💅 SYNOPSIS 💅

u8 w1_triplet (struct w1_master *dev , int bdir );

🦋 ARGUMENTS 🦋

• dev — the master device. Main-character device energy, no cap 👑.
• bdir — the bit to write if both id_bit and comp_bit are 0. Like, both of those are zero? Then this is the bit you write, bestie 💅.

🌸 DESCRIPTION 🌸

Okay so the return bits are literally:

• bit 0 = id_bit
• bit 1 = comp_bit
• bit 2 = dir_taken

⚠️ If both bits 0 & 1 are set, the search should be restarted. Not me warning you — the manpage is warning you 😭.

🔥 RETURN 🔥

Just bit fields, bestie — see above for the deets. Fr fr 👑.
