πŸ’– comedi_open(9) πŸ’–

okay so bestie, this one is from the Kernel API Manual β€” it’s the kernel-side glow-up for opening a COMEDI device, and we’re getting into it 🫢✨

🌸 NAME 🌸

comedi_open β€” Open a COMEDI device from the kernel

✨ SYNOPSIS ✨

struct comedi_device * comedi_open (const char *path );

πŸŽ€ ARGUMENTS πŸŽ€

  • path β€” the manual literally says -- undescribed --, and I’m not gonna invent lore for it, so that’s the whole tea πŸ™ˆ no cap.

πŸ¦‹ DESCRIPTION πŸ¦‹

So what it does: it converts filename to a COMEDI device number and "opens" it β€” but only if it exists and is attached to a low-level COMEDI driver. That’s the vibe check βœ… main character energy fr fr.

⭐ RETURN ⭐

  • On success: a pointer to the COMEDI device β€” slay πŸ’…πŸ‘‘
  • On failure: returns NULL β€” not slay, but facts are facts 😭
