DEVICE_ENABLE(9)

💅 DEVICE_ENABLE(9) 💅

okay so bestie, we're in the Kernel Developer's Manual today and this page is literally about the three little functions that flip a device's enabled flag on and off. it's giving "tiny but powerful" energy. 🎀

---

✨ SYNOPSIS ✨

first things first, you gotta pull in the headers, no cap:

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

and then here are the three icons themselves:

void
device_enable(device_t dev);

void
device_disable(device_t dev);

int
device_is_enabled(device_t dev);

🌸 DESCRIPTION 🌸

okay so picture this: every single device out there has an enabled flag attached to it. that's just how it is. 💅

when a device gets created, it's enabled by default — like, automatically, no effort needed, main character energy from day one. ✨ but you can disable it, and honestly there are legit reasons to! for instance, to prevent a destructive or time consuming probe attempt. 😭 yeah. you don't want that happening.

so here's the vibe check on which function does what:

• device_disable() — call this one to disable a device. bye bestie 👋
• device_enable() — call this one to re-enable it. welcome back queen 👑
• device_is_enabled() — call this one to test whether a device is enabled or not. the vibe check function, fr fr 🦋

that's it. that's the whole thing. lowkey iconic.
