DEVCLASS_GET_DRIVERS(9)

💖 DEVCLASS_GET_DRIVERS 💖

okay bestie, welcome to the Kernel Developer's Manual corner of the internet — this one is devclass_get_drivers(9) and it's literally the "hey, who's in this club?" function for your devclass ✨

✨ NAME ✨

devclass_get_drivers — get a list of drivers in a devclass 🫶

🌸 SYNOPSIS 🌸

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

int
devclass_get_drivers(devclass_t dc, driver_t ***listp, int *countp);

💅 DESCRIPTION 💅

so basically? you hand it a devclass and it goes and collects a list of pointers to all driver instances currently in the devclass. iconic behaviour, no notes.

it drops that list into *listp 👑 and the number of drivers in the list into *countp 🌈

🚨 bestie listen — the memory allocated for the list needs to be freed with free(*listp, M_TEMP), and yes, even if *countp is 0. don't skip it just because the count is zero, that's the trap, that's the vibe check you fail 💀

⭐ RETURN VALUES ⭐

Zero is returned on success 💖 — otherwise, an appropriate error is returned. that's it, that's the deal, fr fr.
