store_wakeup_protocols(9)

✨ store_wakeup_protocols(9) ✨

okay so bestie, welcome to the Kernel API Manual entry for store_wakeup_protocols — literally the glow-up button for your remote control's wakeup IR protocol(s) 💅

---

🎀 NAME 🎀

store_wakeup_protocols — changes the wakeup IR protocol(s). that's it. that's the whole vibe. 🔥

---

🦋 SYNOPSIS 🦋

ssize_t store_wakeup_protocols (struct device *device , struct
device_attribute *mattr , const char *buf , size_t len );

---

🌸 ARGUMENTS 🌸

• device — the device descriptor 🫶 like, the actual device we're talking about here
• mattr — the device attribute struct
• buf — a pointer to the input buffer, i.e. where the new protocol info is chilling
• len — length of the input buffer (how many bytes we're working with, no cap)

---

💖 DESCRIPTION 💖

so this routine is for changing the IR protocol type. it's triggered by writing to /sys/class/rc/rc?/wakeup_protocols — yep, that's the magic little path, write to it and this function wakes up and does its thing ✨

returns len on success, or a negative error code if it's giving flop energy 😭

dev->lock is taken to guard against races between store_wakeup_protocols and show_wakeup_protocols — like, they can't both be main characters at the exact same time, the lock keeps it cute and orderly 🔒👑
