ir_setkeytable(9)

✨ ir_setkeytable(9) ✨

okay so bestie, welcome to the ir_setkeytable page — it lives in the Kernel API Manual and honestly it's a whole vibe. it's part of the kernel's remote-control (rc) fam and it's way less scary than the name makes it sound. let's get into it 🫶

---

🌸 NAME 🌸

ir_setkeytable — sets several entries in the scancode->keycode table 💅

like, yes, plural. several. it's the batch girlie of table-setting. ✨

---

🎀 SYNOPSIS 🎀

int ir_setkeytable (struct rc_dev *dev , const struct rc_map *from );

that's it. two args, one int coming back at you. slay. 💖

---

🦋 ARGUMENTS 🦋

• dev — the struct rc_dev device descriptor. the main character, basically 👑
• from — the struct rc_map you're copying entries from. it's giving "source of truth" energy 🌈

---

💜 DESCRIPTION 💜

no cap, this routine is used to handle table initialization. that's the whole job description and she executes it flawlessly. 🧚

when you need to fill up the scancode->keycode table, ir_setkeytable is the one you call. periodt.

---

⭐ RETURN ⭐

• -ENOMEM — returned if all keycodes could not be inserted 😭 like, it ran out of memory mid-way and didn't get everyone in. tragic.
• otherwise zero — everything made it in. iconic. 🔥

real talk: -ENOMEM literally means not all of them landed, so don't go assuming a partial failure is a full success. she told you. 🙈
