π nct6694_read_msg(9) π
ok so this is a page from the Kernel API Manual, bestie β it's nct6694_read_msg(9) and it's literally the little function that goes and gets your data back from the NCT6694 chip. no cap, it's short, but it's iconic.
β¨ NAME β¨
nct6694_read_msg β Read message from NCT6694 device π«Ά
πΈ SYNOPSIS πΈ
int nct6694_read_msg (struct nct6694 *nct6694 , const struct
nct6694_cmd_header *cmd_hd , void *buf );
like, three args, in that exact order, okay? don't come for me. π
π ARGUMENTS π
nct6694β NCT6694 device pointer β¨ (yes it's the device, it's giving "who am I talking to")cmd_hdβ command header structure π (this is the ~ask~, the vibe you're sending over)bufβ buffer to store the response data π¦ (this is where the answer lands, bestie β you bring the bucket, the chip fills it)
π₯ DESCRIPTION π₯
okay so here's the tea: nct6694_read_msg sends a command to the NCT6694 device and reads the response back. fr fr, that's the whole job. π§
the command header you want is passed in through cmd_hd, and the response data gets stored in buf. literally send + receive, main character energy. π
β RETURN β
- Negative value on error π (it went wrong, that's the sad path)
0on success β¨ (slay, we got it)
lowkey important: it's negative on error, not positive. zero is the win. don't flip it, i'm begging. π
