📦 version 7.3.1, in nixpkgs unstable

✨ ccw_device_tm_intrg ✨

okay so bestie, welcome to the ccw_device_tm_intrg(9) page 💅 this is legit part of the Kernel API Manual, and we are about to make the interrogate function make sense, no cap 🫶

🌸 NAME 🌸

ccw_device_tm_intrg — perform interrogate function 🔍✨

like, that's the whole job. one function, one purpose. iconic behaviour honestly 👑

🎀 SYNOPSIS 🎀

int ccw_device_tm_intrg (struct ccw_device *cdev );

yep that's it. one argument, returns an int. short and sweet, we love to see it 💖

🦋 ARGUMENTS 🦋

  • cdev — the ccw device on which to perform the interrogate function. that's your main character right there, it's the device getting interrogated 👀🔎

💅 DESCRIPTION 💅

so what does it actually do? Perform an interrogate function on the given ccw device, periodt ✨

Return zero on success, non-zero otherwise. that's the whole vibe check — 0 means we ate, anything else means something went sideways 😭🔥

ngl, that's literally all the docs say, so don't come for me asking for more lore — this manpage is giving minimal and we respect it 🎀

🌈 SEE ALSO 🌈

okay so the kernel file in question lives here:

  • Kernel file ./drivers/s390/cio/device_ops.c 📁

and here's the whole friend group, the full squad of related calls — every single one, I'm not skipping anybody, we don't do that here 💜

and that's the page bestie!! 🧚‍♀️ this lil doc is signed off from ./drivers/s390/cio, dated October 2026, and it's living in the Kernel API Manual as ccw_device_tm_intrg(9) — go forth and interrogate responsibly 💖✨🎀
