✨ comedi_is_subdevice_running ✨

okay so bestie, welcome to the Kernel API Manual page for comedi_is_subdevice_running — she's a tiny little kernel function with one job and honestly? she ate. 💅

🌸 NAME 🌸

comedi_is_subdevice_running — literally just checks if an async command is running on a subdevice. that's it. that's the whole vibe check. 🎀

---

🦋 SYNOPSIS 🦋

bool comedi_is_subdevice_running (struct comedi_subdevice *s );

like, look at her. one argument, returns a bool, no drama. main character energy fr fr. ✨

💖 ARGUMENTS 💖

• s — a COMEDI subdevice (struct comedi_subdevice *). this is the cutie you're asking about. 🫶

🔥 RETURN 🔥

She hands back true if an asynchronous COMEDI command is active on the subdevice — and false if it isn't. no in-between, no "it's complicated", just straight yes-or-no. iconic. 👑
