πŸ’– nvme_submit_io_passthru64 πŸ’–

okay so bestie, welcome to the libnvme API manual, section 2 girlypop edition ✨ this one is literally nvme_submit_io_passthru64 and she is here to submit a 64-bit nvme passthrough command. that's the whole name, that's the whole vibe, and yes the 64 is load-bearing πŸ’…


🌸 SYNOPSIS 🌸

int nvme_submit_io_passthru64 (int fd , struct nvme_passthru_cmd64 *cmd
, __u64 *result );

like... three args, one int back. she's giving minimalism πŸ‘‘


πŸŽ€ ARGUMENTS πŸŽ€

  • fd β€” the file descriptor of your nvme device, aka your backstage pass to the drive 🫢
  • cmd β€” the nvme io command you're sending, the actual moment, the main character of this whole operation πŸ’«
  • result β€” an optional field that hands you back the result from the CQE DW0-1. optional bestie!! she can be skipped, no pressure πŸ™ˆ

πŸ¦‹ DESCRIPTION πŸ¦‹

under the hood this uses NVME_IOCTL_IO64_CMD for the ioctl request. that's it, that's the tea β˜• no extra steps, no sneaky behaviour, just the one ioctl. iykyk πŸ”₯


⭐ RETURN ⭐

she gives you the nvme command status if a response came back (peep enum nvme_status_field for the deets on that), or -1 with errno set if things went sideways 😭 so like, always check. always. fr fr.

not me reminding you to check for -1... but also literally check for -1 πŸ’€
