DEVICE_GET_DRIVER(9)

📦 version 15.1, in freebsd 14.5, freebsd 15.1, nixpkgs unstable

💅 DEVICE_GET_DRIVER 💅

okay bestie, so this one's from the Kernel Developer's Manual (section 9, the kernel-functions one, iykyk) and it's genuinely such a tiny little icon. like yes it's short, but it does exactly one thing and it does it flawlessly. main character energy fr fr.

✨ NAME ✨

device_get_driver — the way you get at the current driver that a device is vibing with 💖

🌸 SYNOPSIS 🌸

first you gotta bring in the headers, no cap:

#include <sys/param.h>
#include <sys/bus.h>

then the function itself, literally this:

driver_t *
device_get_driver(device_t dev);

🦋 DESCRIPTION 🦋

so like, you hand it a device and it gives you back the driver that's currently associated with that device. that's it. that's the whole thing. a little lookup, a little "who's your driver bestie", done. ✨

and if the device has no driver? it returns NULL. 🫶 which honestly is so valid of it — it's not gonna invent a driver for you, it's just gonna tell you the truth.

🎀 SEE ALSO 🎀

like, go read those too, they're the friends of this page and they're both iconic in their own right 💜
