board_assembly_show(9)

💖 board_assembly_show(9) 💖

okay so bestie, welcome to the Kernel API Manual — yes we're reading kernel docs together, this is our bonding time 🫶 this one's about board_assembly_show, which is literally the board assembly name getter. slay.

✨ SYNOPSIS ✨

ssize_t board_assembly_show (struct device *cdev , struct
device_attribute *attr , char *buf );

🎀 ARGUMENTS 🎀

• cdev — pointer to the embedded class device. yeah. that one. 👑
• attr — ? … and no, that's not me being mysterious, that's genuinely all the docs say 😭 the manpage itself is out here like "?". iconic honestly.
• buf — the buffer returned 💫 this is where the goods come out.

🌸 DESCRIPTION 🌸

A sysfs 'read-only' shost attribute. that's the whole thing. short queen behavior 💅 read-only means read-only, so don't come for her trying to write, ngl.

so there's a lot of family here, and we're not skipping a single one, because that would be rude 🍓 piling them all into the group chat:

quick vibe check bestie: attr really is documented as ? in the original, so if you're confused — same. don't guess at behavior, just go read the source 😌
