ir_setkeycode(9)

🌸 NAME 🌸

okay bestie, welcome to ir_setkeycode(9) — yes, that's the page title, and the manual is the Kernel API Manual. This icon is here to set a keycode in the scancode->keycode table, no cap.

✨ SYNOPSIS ✨

int ir_setkeycode (struct input_dev *idev , const struct
       input_keymap_entry *ke , unsigned int *old_keycode );

🎀 ARGUMENTS 🎀

• idev — the struct input_dev device descriptor. It's giving main-character device energy, honestly.
• ke — Input keymap entry. Your keymap moment, fr fr.
• old_keycode — result. The old keycode result lands here, bestie.

💅 DESCRIPTION 💅

This routine is used to handle evdev EVIOCSKEY ioctl. That's the whole vibe: it handles that ioctl, periodt.

🔥 RETURN 🔥

-EINVAL if the keycode could not be inserted, otherwise zero. So if the insert says nope, you get -EINVAL; otherwise it's zero. Slay.
