okay so bestie, welcome to the Kernel API Manual β yes, that's the manual name, and yes, we're doing this. today's main character is scsi_set_sense_field_pointer, a little function that's giving very specific energy: it sets the field pointer sense key specific information inside a formatted sense data buffer. π
literally that's the whole vibe. it goes into a sense data buffer you already built and drops the field pointer info where it belongs.
β¨ SYNOPSIS β¨
int scsi_set_sense_field_pointer (u8 *buf , int buf_len , u16 fp , u8 bp
, bool cd );
no cap, five args, and every single one of them matters. let's get into it π«Ά
πΈ ARGUMENTS πΈ
bufβ where you build the sense data. this is the formatted sense data buffer, your canvas, your stage. πbuf_lenβ the buffer length. gotta tell the function how much room it has to work with.fpβ the field pointer to be set. it's au16, it's important, it's the whole point. π₯bpβ the bit pointer to be set. au8, tiny but iconic.cdβ the command/data bit. it's abool, so it's living that true/false life. β
π¦ DESCRIPTION π¦
so what does it actually do? it sets the field pointer sense key specific information in a formatted sense data buffer. that's the tea. π
and the return value? bestie, it's simple and I respect it:
0on success π-EINVALfor invalid sense buffer length π (so like, check yourbuf_len, fr fr)
ngl, that -EINVAL is your little warning bell β a bad length and the function is not having it. no silent weirdness, just a clean error. π
π SEE ALSO π
the kernel file lives at ./drivers/scsi/scsi_common.c β that's home base. π§
