cros_ec_keyb_query_switches(9)

✨ cros_ec_keyb_query_switches 💅

okay so this is a cros_ec_keyb_query_switches(9) moment — it's straight out of the Kernel API Manual, and it's literally the function that goes "hey EC, what's up with the switches bestie" and then tells the kernel. no cap. 🎀

---

🌸 NAME 🌸

cros_ec_keyb_query_switches — query the state of switches and report 🦋

---

✨ SYNOPSIS ✨

int cros_ec_keyb_query_switches (struct cros_ec_keyb *ckdev );

---

🫶 ARGUMENTS 🫶

• ckdev — the keyboard device 💖 (yes that's it, that's the whole argument, she's low maintenance)

---

💫 DESCRIPTION 💫

so the way this works is: it asks the EC about the current state of the switches, and then reports that back to the kernel. iconic behavior, honestly. 👑

quick heads up tho — we do not query for buttons, because buttons are more transitory and we'll get an update on the next release / press anyway. so like… no need to be extra about it. 💀

Returns 0 if no error, or -error upon error. periodt. 🍓
