💅 comedi_put_is_subdevice_running(9) — Kernel API Manual 🎀

okay so bestie, welcome to the Kernel API Manual, we're literally in the kernel driver zone rn 💖

---

✨ NAME ✨

comedi_put_is_subdevice_running — basically you're dropping off the async command running thing on a subdevice, like "k bye, done with that reference" 🫶

---

🌸 SYNOPSIS 🌸

void comedi_put_is_subdevice_running (struct comedi_subdevice *s );

---

🦋 ARGUMENTS 🦋

• s — the COMEDI subdevice. like, the actual subdevice struct you're passing in, that one 👑

---

💫 DESCRIPTION 💫

so here's the tea ☕ — this function decrements the reference counter. and which reference counter, you ask? the exact one that got incremented when comedi_get_is_subdevice_running returned true. so if you called the getter and it said "yeah it's running," you gotta call this to put that reference back before you dip, no cap 🏃‍♀️💨

it's giving symmetry. get → put. iconic behavior fr fr ✨
