comedi_check...gger_arg_max(9)

💖 NAME 💖

okay bestie, welcome to comedi_check...gger_arg_max(9) from the Kernel API Manual — she’s the lowkey little validator with main character energy ✨. Her whole deal is to trivially validate a trigger argument max. No cap.

✨ SYNOPSIS ✨

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

🎀 ARGUMENTS 🎀

• arg — pointer to the trigger arg to validate. literally what it says 🫶
• val — the maximum value the argument should be. that’s the ceiling, bestie.

🦋 DESCRIPTION 🦋

She forces *arg to be no more than val, and if that means setting it to val, she does exactly that. It’s giving “boundary check but make it cute” 💅.

🌸 RETURN 🌸

• 0 — if *arg was already no more than val. slay, it passed ✨
• -EINVAL — if *arg was greater than val. nope, too big, invalid 💀
