comedi_check...gger_arg_min(9)

🎀 comedi_check_trigger_arg_min — NAME 🎀

okay so bestie, welcome to the comedi_check_trigger_arg_min(9) page from the Kernel API Manual 💖 — this one is literally the tiniest little validator: comedi_check_trigger_arg_min — trivially validate a trigger argument min. yes, "trivially", the kernel devs said it themselves, it's giving humble icon behavior ✨

---

🦋 SYNOPSIS 🦋

int comedi_check_trigger_arg_min (unsigned int *arg , unsigned int val );

---

🌸 ARGUMENTS 🌸

• arg — pointer to the trigger arg you wanna validate 🫶 like, this is the thing being checked, not the thing doing the checking.
• val — the minimum value the argument should be. the floor. the bare minimum. we stan a boundary 💅

---

✨ DESCRIPTION ✨

so here's the whole vibe: it forces *arg to be at least val — and if *arg is being a little underachiever and is less than val, it just sets it to val for you. no cap, it will literally overwrite your value to lift it up to the minimum. main character energy, honestly 👑

---

💀 RETURN 💀

• 0 — slay, *arg was already at least val. nothing to do, we love a no-op 🎀
• -EINVAL — oop, *arg was less than val. it gets bumped up to val and you get handed an -EINVAL to deal with 😭
