qla2x00_build_scsi_iocbs_64(9)

💖 NAME 💖

okay so bestie, this page is the Kernel API Manual moment for qla2x00_build_scsi_iocbs_64(9) — and what it does is literally right there in the name: it builds an IOCB command, but make it 64-bit-capable IOCB types, periodt. ✨

The way this function is described: "Build IOCB command utilizing 64bit capable IOCB types." No cap, that's the whole vibe. 💅

---

✨ SYNOPSIS ✨

void qla2x00_build_scsi_iocbs_64 (srb_t *sp , cmd_entry_t *cmd_pkt ,
       uint16_t tot_dsds );

Note the void up front, bestie — this one's not handing you a return value, it's just out here doing the work. 🫶

🌸 ARGUMENTS 🌸

Three lil' parameters, and they all matter, so let's give them their main character energy:

• sp — the SRB command to process 👑 like, this is the command that's getting processed, pls respect them.
• cmd_pkt — a Command type 3 IOCB 🎀 yes, type 3 specifically, don't come at me with other types.
• tot_dsds — Total number of segments to transfer 🔥 the full count, all the segments, every last one.
