megaraid_mbox_app_hndl_show(9)

📦 version 7.3.1, in nixpkgs unstable

💅 megaraid_mbox_app_hndl_show(9) — from the Kernel API Manual, bestie

okay so picture this: it's a kernel API manual page, and the star of the show is megaraid_mbox_app_hndl_show. she's a sysfs show function and honestly she ate. let's get into it 🎀

✨ NAME ✨

megaraid_mbox_app_hndl_show — display application handle for this adapter 💫

the whole vibe: she shows you the handle. that's it. that's the post.

🌸 SYNOPSIS 🌸

ssize_t megaraid_mbox_app_hndl_show (struct device *dev , struct device_attribute *attr , char *buf );

literally three params, no cap. here's the tea on each one 👇

🦋 ARGUMENTS 🦋

  • dev — the class device object representation for the host. she's the main character device, the one we're talking about 🫶
  • attr — the device attribute. note that it's (unused) — she's just here for the vibes, not the function 💀
  • buf — the buffer to send data to. this is where the output goes to live ✨

💖 DESCRIPTION 💖

so what does she actually do? she displays the handle used by the applications while they're executing management tasks on the adapter. iconic behaviour honestly 👑

and here's the fun part: we don't talk to applications directly (ew, no, we don't interface with them like that 🙈). instead, we invoke a management module API to get the adapter handle. middle-man energy, but make it kernel. it's giving delegation, it's giving "let the module handle it", and honestly? slay.

🔥 SEE ALSO 🔥

bestie. buckle in. this list is long — grab a snack 🍓 — but every single one of these is in the kernel file ./drivers/scsi/megaraid/megaraid_mbox.c:

like I said. a lot of friends. iykyk 💜

okay that's the page!! tysm for reading, mwah 💋 — and before you go, the whole thing lives over in ./drivers/scsi/megaraid and it's dated October 2026, so jot that down bestie, it's part of the lore 🌈⭐
