💖 sd-device — bestie's guide to peeking at ur devices 💖

okay so real talk, this is SD-DEVICE(3), page three of the manual, and it's literally the whole sd-device situation. buckle up 🎀

✨ NAME ✨

sd-device — the API for enumerating and introspecting local devices. yes bestie, enumerating and introspecting. it's giving main character energy for your hardware 👑

🌸 SYNOPSIS 🌸

#include <systemd/sd-device.h>
pkg-config --cflags --libs libsystemd

like, that's it. that's the whole vibe check to get started 💅

🦋 DESCRIPTION 🦋

so sd-device.h is part of libsystemd(3) and it hands you an API to introspect and enumerate devices on the local system. think of it as your little backstage pass to the device world 🎟️

it's a programmatic interface to the database of devices and their properties managed by systemd-udevd.service(8). no cap, that's the whole point.

and the tea ☕: this API is a replacement for libudev(3) and libudev.h. out with the old, in with the new, periodt.

if you wanna know more about the functions available (and honestly why wouldn't you), go see:

they've got the details, iykyk 🫶

⭐ NOTES ⭐

okay important stuff, don't scroll past this one 🙈

  • Functions described here are available as a shared library, which can be compiled against and linked to with the libsystemd pkg-config(1) file.
  • The code described here uses getenv(3), which is declared to be not multi-thread-safe. so like, the code calling the functions described here must not call setenv(3) from a parallel thread. the recommendation is to only do calls to setenv() from an early phase of the program when no other threads have been started. fr fr, don't be messy about it 💀
honestly this is the "don't touch the stove while it's hot" of the whole page. respect the threads, bestie 🔥
