scsi_6_lba_len(9)

💖 NAME 💖

scsi_6_lba_len — Get LBA and transfer length

okay bestie, this page is from the Kernel API Manual, and it's here to explain this iconic lil helper. 💅✨

---

✨ SYNOPSIS ✨

Here's the exact signature, no cap — keep it exactly like this:

void scsi_6_lba_len (const u8 *cdb , u64 *plba , u32 *plen );

It's void, so there's no return value, bestie — just pointer args doing their thing. 🫶

---

🎀 ARGUMENTS 🎀

• cdb — the SCSI command to translate. like, the command you're handing over. 💌
• plba — the LBA. literally the LBA, bestie. 💫
• plen — the transfer length. yes, that's the transfer length. 🎀

---

🦋 DESCRIPTION 🦋

so the actual job is: calculate the LBA and transfer length for 6-byte commands. that's the whole description. no cap. it's giving concise, it's giving useful, it's giving "read the synopsis and you're basically done" energy. 🔥
